In recent years, the sanitization of environments, devices, and objects has become mandatory to improve human and environmental safety, in addition to individual protection and prevention measures. International studies considered ozone one of the most useful and easy sanitization methods for indoor environments, especially hospital environments that require adequate levels of disinfection. The purpose of this work was to evaluate the microclimate influence on sanitizing procedure for indoor settings with ozone, to prevent infections and ensure the safe use of the environments. The concentration of ozone was measured during sanitization treatment and estimation of microorganisms’ survival on the air and different contaminated plates after the sanitization operations were performed. The results demonstrated a significant reduction in the microbial count that always fell below the threshold value in different conditions of distance, temperature, and relative humidity.

The growing demand to reduce chlorine usage and control disinfection byproducts increased the development of new strategies in wastewater treatments. Organic peracids are increasingly attracting interest in disinfection activities as a promising alternative to chlorine and chlorine-based agents. In this study, we assessed the antimicrobial properties against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) of a new organic peracid, permaleic acid (PMA) compared with the reference peracetic acid (PAA). Disinfectant properties were evaluated by i) disk diffusion agar, ii) broth microdilution, iii) antibiofilm properties. PMA demonstrated a 10- and 5-fold decrease in the microbial inhibitory concentration (MIC) value against E. coli and S. aureus respectively, compared to PAA. Results showed greater efficacy of PMA regarding wastewater (WW) and treated wastewater (TWW) disinfection at low concentrations. Furthermore, the biofilm degradation ability was only observed following PMA treatment, for both strains. Bacterial regrowth from biofilm matrix after PAA and PMA disinfection, in the absence and presence of organic matter, was evaluated. PMA was more efficient than PAA to prevent the regrowth of planktonic cells of S. aureus and E. coli. After PAA and PMA treatment, in the presence of organic matter, the bacterial regrowth inhibition was maintained up to 10 and 5 g/L, respectively. Based on these results, PMA could be used as a valid alternative to the currently used disinfection methods.

In this paper, we analysed the efflorescences present in the frescos of a monumental complex named S. Pietro a Corte situated in the historic centre of Salerno (Campania, Italy). The groundwater of the historic centre is fed by two important streams (the Rafastia and the Fusandola) that can be the sources of water penetration. The aims of this work are to (i) identify the stream that reaches the ancient frigidarium of S. Pietro a Corte and (ii) characterize the efflorescences on damaged frescos in terms of chemical nature and sources. In order to accomplish the first aim, the water of the Rafastia river (7 samples) and the water of the Fusandola river (7 samples) were analysed and compared with the water of a well of the Church (7 samples). The ionic chromatography measurements on the water samples allowed us to identify the Rafastia as the river that feeds the ancient frigidarium of S. Pietro a Corte. To investigate the nature and the origin of the efflorescences (our second aim), anionic chromatography analyses, X-ray diffraction measurements, and the isotopic determination of nitrogen were performed on the efflorescences (9 samples) and the salts recovered from the well (6 samples). Results of these analyses show that efflorescences are mainly made of potassium nitrate with a δ15N value of + 9.3 ± 0.2‰. Consequently, a plausible explanation for their formation could be the permeation of sewage water on the walls of the monumental complex.

Several studies indicate that semen quality has strongly declined in the last decades worldwide. Air pollution represents a significant co-factor with the COVID-19 impact and has negative effects on the male reproductive system, through pro-oxidant, inflammatory and immune-dysregulating mechanisms. It has recently been reported that chronic exposure to PM2.5 causes overexpression of the alveolar ACE2 receptor, the entry route of SARS-CoV-2 into the organism shared by the lungs and testis where expression is highest in the body. In the testis, the ACE2/Ang-(1–7)/MasR pathway plays an important role in the regulation of spermatogenesis and an indirect mechanism of testicular damage could be due to the blockade of the ACE2 receptor by SARS-CoV-2. This prevents the conversion of specific angiotensins, and their excess causes inflammation with the overproduction of cytokines. PM2.5-induced overexpression of the alveolar ACE2 receptor, in turn, could increase local viral load in patients exposed to pollutants, producing ACE2 receptor depletion and compromising host defenses. By presenting an overall view of epidemiological data and molecular mechanisms, this manuscript aims to interpret the possible synergistic effects of both air pollution and COVID-19 on male reproductive function, warning that the spread of SARS-CoV-2 in the fertile years may represent a significant threat to global reproductive health. All of this should be of great concern, especially for men of the age of maximum reproductive capacity, and an important topic of debate for policy makers. Altered environmental conditions, together with the direct and indirect short- and long-term effects of viral infection could cause a worsening of semen quality with important consequences for male fertility, especially in those areas with higher environmental impact.

In this study, we used, for the first time, disinfectant in the vapour phase to treat fabrics and textiles. The methodology was applied to disinfect fabrics with different origins, such as cotton, linen, silk, wool, polyester, viscose, which are the most common raw materials used in clothing products. We vaporized three solutions based on ethanol, hydrogen peroxide, benzalkonium chloride, at different concentrations (1.5–0.05 - 0.01 mg/m3) to simulate the traditional disinfection processes (laundry washing, scrubbing, and surface cleaning) and at three different exposure times (1 -5- 10 min). Experimental results demonstrated that vapour phase disinfection could be a suitable alternative to the traditional processes, with very good efficiency in reducing microbial load. The main advantage of using vapour phase methodologies is related to cheapness, water consumption reduction, and easy-to-operate method in comparison to traditional methodologies such as the water-based. Moreover, there is no damage or lightning to the colour of the disinfected textiles.

The objectives of this study were to evaluate the psychological factors of health perception, mistrust, anxiety, fear, and indecision of Italians vaccinated against COVID-19, and conduct an analysis of the relationships between these factors and other variables: sex, vaccine priority ministerial categories, and the type and dose of vaccine. The participants included 1564 subjects who joined the vaccination campaign at the COVID-19 Vaccination Center in Salerno, Italy. A survey was conducted in the reference period March–April 2021 using a brief anamnestic questionnaire. In addition, the following standardized scales were used: the State–Trait Anxiety Inventory (STAI-Y) and the Short Form Health Survey (SF-12). The results showed that, in terms of the type of vaccine received, the interviewees felt more confident in having received the Comirnaty (Pfizer-BioNTech, 23.5%) and Vaxzevria (AstraZeneca, 18.6%) vaccines—feeling less tense (2.1%; Vaxzevria (AstraZeneca) = 3.2%), frightened (1%; Vaxzevria (AstraZeneca) = 1.4%), not at all nervous (61.1%; Vaxzevria (AstraZeneca), 43.6%), and not at all/undecided (67.9%; Vaxzevria (AstraZeneca), 58.6%). Regarding the mood and psychological states considered at the different vaccine administration times, other important differences emerged as the interviewees reported higher levels of tension, nervousness, and fear during the first phase of vaccine administration. Specifically, 40.7% (second dose, 32.7%) felt somewhat tense at the first dose, 26.4% felt frightened (second dose, 21.8%), and 33.8% felt nervous (second dose, 26.8%). The perceived state of health also increased at the end of the vaccination cycle, as, at the second dose, 15.4% of the sample reported an evaluation of “excellent” (first dose, 12.4%).

The epidemic of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has impacted worldwide with its infectious spread and mortality rate. Thousands of articles have been published to tackle this crisis and many of these have indicated that high air pollution levels may be a contributing factor to high outbreak rates of COVID-19. Atmospheric pollutants, indeed, producing oxidative stress, inflammation, immuno-unbalance, and systemic coagulation, may be a possible significant co-factor of further damage, rendering the body prone to infections by a variety of pathogens, including viruses. Spermatozoa are extremely responsive to prooxidative effects produced by environmental pollutants and may serve as a powerful alert that signals the extent that environmental pressure, in a specific area, is doing damage to humans. In order to improve our current knowledge on this topic, this review article summarizes the relevant current observations emphasizing the weight that environmental pollution has on the sensitivity of a given population to several diseases and how semen quality, may be a potential indicator of sensitivity for virus insults (including SARS-CoV-2) in high polluted areas, and help to predict the risk for harmful effects of the SARS-CoV-2 epidemic. In addition, this review focused on the potential routes of virus transmission that may represent a population health risk and also identified the areas of critical importance that require urgent research to assess and manage the COVID-19 outbreak.

Endocrine-disrupting compounds (EDCs) as emerging contaminants have accumulated in the aquatic environment at concentration levels that have been determined to be significant to humans and animals. Several compounds belong to this family, from natural substances (hormones such as estrone, 17-estradiol, and estriol) to synthetic chemicals, especially pesticides, pharmaceuticals, and plastic-derived compounds (phthalates, bisphenol A). In this review, we discuss recent works regarding EDC occurrence in the aquatic compartment, strengths and limitations of current analytical methods used for their detection, treatment technologies for their removal from water, and the health issues that they can trigger in humans. Nowadays, many EDCs have been identified in significant amounts in different water matrices including drinking water, thus increasing the possibility of entering the food chain. Several studies correlate human exposure to high concentrations of EDCs with serious effects such as infertility, thyroid dysfunction, early puberty, endometriosis, diabetes, and obesity. Although our intention is not to explain all disorders related to EDCs exposure, this review aims to guide future research towards a deeper knowledge of EDCs’ contamination and accumulation in water, highlighting their toxicity and exposure risks to humans.

The most important parameter to obtain an appropriate preservation condition of museum environments concerns the indoor air quality. The exposure of artwork and materials to gaseous and particulate pollutants introduced by visitors and either indoor or outdoor sources contributes to their decay. In this work, we evaluated the possible monitoring of the visitors’ influence using the stable carbon isotopic ratio of CO2 and the concentration of NH3 as a real-time tool. The study was done in the Refectory of Santa Maria delle Grazie (Milan, Italy) which houses one of the most important paintings of Leonardo da Vinci, the Last Supper, and had more than 400,000 visitors in 2019. The results confirmed a good correlation between the presence of tourists inside the museum and the variation of δ13C value during the visits and the closure of the museum. The variation of indoor atmospheric δ13C was influenced by the presence of visitors in the Refectory and delineates the way done from the entrance to the exit. In the same way, the concentration of NH3 was influenced by the presence of visitors and confirmed the role of this one on preservation methodology for indoor air quality in the museum. This new methodology can be used as a supplemental and non-invasive tool to help in calibrating microclimatic conditions through the ventilation rate and air filtration systems in the museum and to manage the number of visitors per turn.

Microplastics (MP) have recently been considered as emerging contaminants in the water environment. In the last number of years, the number of studies on MP has grown quickly due to the increasing consciousness of the potential risks for human health related to MP exposure. The present review article discusses scientific literature regarding MP occurrence and accumulation on the aquatic compartment (river, lake, wastewater, seafood), the analytical methods used to assess their concentration, their fate and transport to humans, and delineates the urgent areas for future research. To better analogize literature data regarding MP occurrence in the aquatic compartment we subdivided papers based on sampling, analytical methods, and concentration units with the aim to help the reader identify the similarities and differences of the considered research papers, thus making the comparison of literature data easier and the individuation of the most relevant articles for the reader’s interests faster. Furthermore, we argued about several ways for MP transport to humans, highlighting some gaps in analytical methods based on the reviewed publications. We suggest improving studies on developing standardized protocols to collect, process, and analyze samples.

Chemical risk in hospital settings is a growing concern that health professionals and supervisory authorities must deal with daily. Exposure to chemical risk is quite different depending on the hospital department involved and might origin from multiple sources, such as the use of sterilizing agents, disinfectants, detergents, solvents, heavy metals, dangerous drugs, and anesthetic gases. Improving prevention procedures and constantly monitoring the presence and level of potentially toxic substances, both in workers (biological monitoring) and in working environments (environmental monitoring), might significantly reduce the risk of exposure and contaminations. The purpose of this article is to present an overview on this subject, which includes the current international regulations, the chemical pollutants to which medical and paramedical personnel are mainly exposed, and the strategies developed to improve safety conditions for all healthcare workers.

Background: The safety of healthcare workers exposed to formaldehyde remains a great matter of concern for healthcare management units. This work aimed at describing the results of a combined monitoring approach (environmental and biological) to manage occupational exposure to formaldehyde in a hospital setting.Design and Methods: Environmental monitoring of working spaces and biological monitoring of urinary formaldehyde in 16 exposed healthcare workers of the Anatomic Pathology Unit of a University Hospital in Southern Italy was performed on a four-year timescale (2016-2019).Results: Values of aero-dispersed formaldehyde identified were on average low; although workers' urinary formaldehyde levels were also minimal, the statistical analysis highlighted a slight weekly accumulation.Conclusions: Our data confirm that both environmental and biological monitoring are important to identify risk situations, in particular when values of hazardous compounds are below the accepted occupational exposure levels.

In this study, we evaluated indoor air quality to highlight the effects of environmental pollution in the field of cultural heritage. In particular, two important archeological places in the old part of the city of Salerno, Italy, were analyzed: Fruscione Palace and S. Pietro a Corte. The work focused on the influence of tourists on environmental pollution correlated to indoor air quality during some social and cultural events. Moreover, we focused on the possible use of the carbon isotopic composition of CO2 as a tool for environmental studies in the field of cultural heritage. The results showed a good relationship between the isotopic composition of CO2 and the variation of pollutants concentration in the air, demonstrating that it is a valid tool and non-invasive marker to monitor environmental pollution of museums and cultural heritage sites.

In this work permaleic acid (PMA) was investigated as possible disinfecting agent and compared to peracetic acid (PAA) in real tap water and wastewater. Preliminary tests in lysogeny broth (LB) were also performed. PMA was synthesized from maleic anhydride and hydrogen peroxide and, for the first time, its antimicrobial activity was evaluated with respect to the growth inhibition of E. coli. The effect of the pH and bivalent ions, typically occurring in real water matrices (namely, Mg2+ and Ca2+), was also investigated. pKa values for PMA were calculated for the first time by DFT calculations. The concentration of bivalent ions strongly affected disinfection efficiency with PMA (Ca2+=0.33 mgL−1 and Mg2+=0.35 mgL−1: 100% E. coli reduction > log 5; Ca2+=13.3 mg L−1 and Mg2+=25.6 mg L−1: E. coli reduction < log 1, after 60 min), and such results were supported by DFT modelling outcomes (pKa2 of PMA 7.3) and disinfection tests in presence of EDTA chelating agent. More alkaline pH conditions drastically decreased PMA disinfection (pH = 5: > log 5 E.coli reduction; pH = 9: < log 1 E.coli reduction, after 60 min). PMA disinfection efficiency is strongly affected by the target water quality, the concentration of metal bivalent ions and the initial pH.

Bloodstream infections (BSIs) are among the leading causes of morbidity and mortality worldwide, among infectious diseases. Local knowledge of the main bacteria involved in BSIs and their associated antibiotic susceptibility patterns is essential to rationalize the empiric antimicrobial therapy. The aim of this study was to define the incidence of infection and evaluate the antimicrobial resistance profile of the main pathogens involved in BSIs. This study enrolled patients of all ages and both sexes admitted to the University Hospital “San Giovanni di Dio e Ruggi d’Aragona”, Salerno, Italy between January 2015 to December 2019. Bacterial identification and antibiotic susceptibility testing were performed with Vitek 2. A number of 3.949 positive blood cultures were included out of 24,694 total blood cultures from 2015 to 2019. Coagulase-negative staphylococci (CoNS) were identified as the main bacteria that caused BSI (17.4%), followed by Staphylococcus aureus (12.3%), Escherichia coli (10.9%), and Klebsiella pneumoniae (9.4%). Gram-positive bacteria were highly resistant to Penicillin G and Oxacillin, while Gram-negative strains to Ciprofloxacin, Cefotaxime, Ceftazidime, and Amoxicillin-clavulanate. High susceptibility to Vancomycin, Linezolid, and Daptomycin was observed among Gram-positive strains. Fosfomycin showed the best performance to treatment Gram-negative BSIs. Our study found an increase in resistance to the latest generation of antibiotics over the years. This suggests an urgent need to improve antimicrobial management programs to optimize empirical therapy in BSI.

Background and objectives: Ozone has been one of the most investigated and discussed sanitization methods. This paper reports a procedure to sanitize air hospital environments, in particular chirurgical surgery rooms that require high levels of disinfection. The purpose of this work was the development and implementation of a cleansing and sanitizing procedure for critical clinical settings with ozone, to prevent hospital infections by the elimination of all toxic and harmful microorganisms in the air, and ensure safe use for operators and patients. Materials and Methods: The protocol for the study involved a structured selection of a representative environment of healthcare structures such as high, medium, and low-risk settings in air and examples of hospital furniture. Results: The concentration of ozone was measured during sanitization treatment and the estimation of the total microbial count in the air and on different surfaces before and after the sanitization operations was performed. The results demonstrated a significant reduction in the microbial count that always fell below the threshold value. Conclusions: Currently, there are no air treatment strategies available for inactivating airborne organisms during hospital outbreaks, which is most probably due to the lack of approved protocols.

The increasing emergence and spread of multiresistant microorganisms in hospital wards is a serious concern. Traditional protocols are often not sufficient to protect patients susceptible to serious and life-threatening infections, therefore new strategies for decontaminating hospital environments are crucial to reducing microbial transmission and the spread the nosocomial infections. The adoption of modern technologies is indicated to supplement traditional methods and to improve desired levels of surface disinfection. This work aims to report the development, implementation, and validation of cleansing and sanitizing procedure for critical clinical settings through the innovative use of disposable cloths pre-impregnated with solutions containing different active formulations and biocidal agents, relating to the areas to be treated (low, moderate, high-risk). The implementation and validation of the sanitizing system were conducted in different wards of two healthcare structures. The protocol for the study involved a structured selection of representative surfaces, such as the floor, bathroom, desk, and beds. Microbiological analyses were performed according to ISO 4833-1:2013. The efficiency of the proposed system was measured through the estimation of total microbial count values on the different surfaces before and after the sanitization operations by traditional methods and by the system described here. The results demonstrated a significant reduction in the microbial count that always fell below the threshold value. For the analyzed surfaces such as shower tray, bathroom floor, toilet edge, the traditional system had an effectiveness of less than 10%, whereas pre-impregnated cloths succeed to eliminate about 90% of the bacteria present. As an example, on the floor we observed a microbial count reduction from >42 to 10 CFU/11 cm2 with the new method (76% of colonies were destroyed), while with the traditional one we have a reduction from >42 to 28 CFU/11 cm2 (33% of microbial colonies). Moreover, the advantages of using this sanitization system are not limited to disinfecting surfaces and limiting cross-contamination but involve all activities related to the cleaning and disinfection operations, including the training and education of the operators and traceability of the operations. The innovative disinfection and cleaning protocol used in the present study proved to be a highly valuable alternative to the traditional cleaning procedures in healthcare settings for the sanitizing process of all kinds of surfaces. All tools were specifically designed to improve disinfection efficiency and to reduce the problems associated with traditional methods, such as preventing cross-contamination events, limiting the physical efforts of operators, and avoiding incorrect practices. Our findings add support to the knowledge that an effective sanitization procedure is critical in minimizing microorganisms' transmission and cross-contamination.

Here we report the results obtained for a strain isolated from a polluted site and classified as Azospira sp. OGA 24. The capability of OGA24 to utilize perchlorate and nitrate and the regulation of pathways were investigated by growth kinetic studies and analysis of messenger RNA (mRNA) expression of the genes of perchlorate reductase alpha subunit (pcrA), chlorite dismutase (cld), and periplasmic nitrate reductase large subunit (napA). In aerobic conditions and in a minimal medium containing 10 mM acetate as carbon source, 5.6 ± 0.34 mmol L−1 perchlorate or 9.7 ± 0.22 mmol L−1 nitrate were efficiently reduced during the growth with 10 mM of either perchlorate or nitrate. In anaerobiosis, napA was completely inhibited in the presence of perchlorate as the only electron acceptor, pcrA was barely detectable in nitrate-reducing conditions. The cell growth kinetics were in accordance with expression data, indicating a separation of nitrate and perchlorate respiration pathways. In the presence of both compounds, anaerobic nitrate consumption was reduced to 50% (4.9 ± 0.4 vs. 9.8 ± 0.15 mmol L−1 without perchlorate), while that of perchlorate was not affected (7.2 ± 0.5 vs. 6.9 ± 0.6 mmol L−1 without nitrate). Expression analysis confirmed the negative effect of perchlorate on nitrate respiration. Based on sequence analysis of the considered genes and 16S ribosomal gene (rDNA), the taxonomic position of Azospira sp. OGA24 in the perchlorate respiring bacteria (PRB) group was further defined by classifying it in the oryzae species. The respiratory characteristics of OGA24 strain make it very attractive in terms of potential applications in the bioremediation of environments exposed to perchlorate salts.

This study focuses on the application of stable carbon isotope analysis to determine the origin of commercial surfactants and cleaning products, especially used in quality process by chemical companies. The δ13C value was applied to commercial surfactants, such as ethoxylate alcohol, sodium lauryl sulfate, alkyl polyglucoside with different origin, that are the most common raw materials used in cleaning products. In this study, the isotopic analysis was performed on mixtures of commercial surfactants to simulate the commercial detergent formulations (handwashing, multisurface cleaner and degreaser) and then on bulk professional cleaning products to match relationship between isotope carbon composition and concentration of surfactants in real samples. This study demonstrated that δ13C was correlated to the origin of surfactants. In particular we analyzed five samples of biobased surfactants, with δ13C value from −22,6‰ to −28,0‰, and six samples from carbon fossil raw material, with δ13C value from −28,5‰ to −32,0‰, which were the most common raw material used in commercial cleaning products. Isotope carbon composition was also applied on mixtures of biobased and fossil surfactants to simulate and perform the method for stable carbon isotope analysis of commercial cleaning products. Furthemore the results assessed the relationship between stable carbon isotope ratio values and surfactant concentration in mixtures: for example in 50% mixtures of biobased (δ13C −22,6‰) and synthetic surfactant (δ13C −32,5‰), we found a δ13C value −28,00‰. The main advantage in using δ13C analysis is related to cheapness and easy-to-operate method in comparison to radiocarbon methodology.
