Acid mine drainage (AMD) occurs naturally in abandoned coal mines, and it contains hazardous toxic elements in varying concentrations. In the present research, AMD samples collected from an abandoned mine were treated with fly ash samples from four thermal power plants in Singrauli Coalfield in the proximate area, at optimized concentrations. The AMD samples were analyzed for physicochemical parameters and metal content before and after fly ash treatment. Morphological, geochemical and mineralogical characterization of the fly ash was performed using SEM, XRF and XRD. This laboratory-scale investigation indicated that fly ash had appreciable neutralization potential, increasing AMD pH and decreasing elemental and sulfate concentrations. Therefore, fly ash may be effectively used for AMD neutralization, and its suitability for the management of coalfield AMD pits should be assessed further.

Biosolids made from municipal sludge are an attractive solution instead of chemical fertilization. Nevertheless, their effects on the ecosystem should always be considered. In the present study, anaerobically digested sludge was subjected to two leaching methods (EN 12457-2 and NEN 7341) and the main physicochemical parameters were measured in the leachates. The aquatic organisms Daphnia magna and Vibrio fischeri were exposed to the leachates in order to test for adverse effects. Mixtures of biosolid/solid, simulating the high dose of 80 tn/ha, were also created, and the same parameters were measured for EN 12457-2 leachates. The results show a strong seasonal variation for the results for the municipal sludge, even though the sludge did not originate from a touristic area. The biosolid/solid mixtures did not produce toxic responses to the organism tested. Nevertheless, the parameters nitrites and nitrates in the leachates were increased in relation to control and they continued to increase even at Day 40 post-application. This increase was soil-type-dependent. The biosolids in question could be used for field fertilization, however measures should be taken against underground water nitrate pollution.

Sludge-based biosolids can be used for crop fertilization and for soil enrichment with organic matter. The prerequisites for their application are laid out in 86/278/EEC which sets limits for metals of toxicological concern in the biosolid and in the recipient soil. In this context, three kinds of sludge-based biosolids from a municipal wastewater treatment plant were submitted to the leaching tests EN 12457-2 and ΝΕΝ 7341. The leachates were examined for their physicochemical, chemical, and ecotoxicological characteristics four times within a year. Even in the more aggressive metal leaching method (ΝΕΝ 7341), results were much lower than the limits set in Council Directive 86/278/EEC. Correlations were noted between numerous parameters and principal component analysis grouped them in 3 components explaining 76% of total variation. These leaching tests were also performed on soil-biosolid samples from another investigative research in which two of the three kinds of biosolids had been incorporated in corn fields at doses 0, 20, and 40 tn/ha. EN 12457-2 leaching tests indicated that Ni and Cd leaching was affected by biosolid incorporation in soil, in relation to the type of the receiving soil (clay or sand). The leachates from the soil-biosolid mixtures were practically not toxic for the organisms tested (D. magna, V. fischeri, higher plants). In summary the biosolids were considered of low environmental risk when utilized in the field. A detailed risk assessment encompassing both chemical and ecotoxicological analysis is necessary for integrated evaluation of biosolids.

The status of waste of electrical and electronic equipment (WEEE) recycling in a middle-sized industrialized city in Greece has been investigated, through the application of structured questionnaires to 310 citizens from the municipal units of Volos and Nea Ionia, asking for their habits and opinions on this kind of recycling. The underlying factors affecting the intention of these citizens to perform WEEE recycling were investigated, applying aspects of the Theory of Planned Behavior (TPB). Results show that there is an underperformance of WEEE recycling with 57% of the sample answering that they have never participated in WEEE recycling. A number of behavioral factors, based on TPB predictors, affect the intention of these citizens to participate in WEEE recycling schemes, namely total attitude, willingness to pay, information status regarding WEEE recycling and subjective norm. These findings may aid in improving marketing strategies for WEEE recycling of the general public. Investigation into pro-environmental incentives in Greece and in other countries with similar WEEE recycling management is urgently needed.

Wastewater is not a waste but a valuable resource that should be reused. Nevertheless, it should be devoid of physical, chemical, and microbiological parameters that can harm the consumer. Along with the multitude of possible pollutants found in wastewater treatment plants (WWTPs), emerging pollutants, such as Personal Care Products (PCPs), have arisen. The present research examines some of the main ingredients commonly found in PCPs, focusing on their toxicological profile on their occurrence in WWTPs influents and effluents worldwide and on their persistence and biodegradability. A small-scale market sampling of PCPs was performed in Athens, Greece, in June 2019, and their individual ingredients were recorded, coded according to their main activity, scanned for the presence of ingredients of important toxicological profile, and finally analyzed for the presence of other candidates of toxicological interest. Results show that some ingredients of concern (i.e., parabens and triclosan) are a decreasing trend. On the other hand, information on the presence of synthetic musks and perfume synthesis is scarce and encumbered by brand protection. Finally, UV filters are numerous, and they are used in various combinations, while other ingredients of toxicological interest are also present. Since the reclaimed water may well be used to cover irrigation needs in Greek areas with water deficiency or to enrich bodies of surface water, it is important to know what PCP ingredients are on the rise in the market, to monitor their presence in WWTPs influents and effluents and to extend research on their environmental fate and behavior.

The constant increase of municipal solid wastes (MSW) as well as their daily management pose a major challenge to European countries. A significant percentage of MSW originates from household activities. In this study we calculate the costs of setting up and running a zero-waste mortar-producing (ZWMP) process utilizing MSW in Northern Greece. The process is based on a thermal co-processing of properly dried and processed MSW with raw materials (limestone, clay materials, silicates and iron oxides) needed for the production of clinker and consequently of mortar in accordance with the Greek Patent 1003333, which has been proven to be an environmentally friendly process. According to our estimations, the amount of MSW generated in Central Macedonia, Western Macedonia and Eastern Macedonia and Thrace regions, which is conservatively estimated at 1,270,000 t/y for the year 2020 if recycling schemes in Greece are not greatly ameliorated, may sustain six ZWMP plants while offering considerable environmental benefits. This work can be applied to many cities and areas, especially when their population generates MSW at the level of 200,000 t/y, hence requiring one ZWMP plant for processing.

The valuable 2-(tert-butyldisulfanyl)heterocycles were effectively synthesized from 2-mercaptoheterocycles and tert-butanesulfinamide via unusual condensation. The reaction between 2-mercapto sulfur-containing heterocycles and tert-butanesulfinamide was performed under ligand-free CuI-catalyzed conditions. The synthetic processes described herein are simple, cost-efficient, and practical. Furthermore, a plausible mechanism is proposed for this transformation.

Polycyclic aromatic hydrocarbons (PAH) are broad environmental contaminants, which, due to their lipophilic profile, tend to be absorbed on particles and finally accumulate in marine environments. Due to their cumulative power of adsorption, bivalves are major bioindicators of PAH pollution. Substantial research has been performed on the effects of PAH pollution on marine bivalves. Here we review PAH analysis using bivalves and effects of PAH on bivalves. Specific focus is given on: (1) PAH analytical methodologies and their performance, (2) levels of marine PAH as measured through bivalves within the last decade; current pollution status and (3) health effects of PAH on bivalves.

Persistent chemicals and emerging pollutants are continuously detected in marine waters and biota. Out of these, polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCs) are significant contaminants with decades of presence in the marine environment. The Mediterranean Sea is an ecosystem directly affected by a variety of anthropogenic activities including industry, municipal, touristic, commercial and agricultural. The Mediterranean mussel (Mytilus galloprovincialis) is a filter feeder, which presents wide distribution. In this regard, the specific organism was used as a biological indicator for the monitoring and evaluation of pollution in the studied areas with focus on the mentioned chemical groups. Pristine Turkish sites with minimum effect from anthropogenic activities, in contrast with Greek sites which were subjected to heavy industrial and shipping activity, were selected. A gas chromatographic tandem mass spectrometric method (GC-MS/MS) was developed and validated to monitor 34 compounds (16 EPA priority PAHs and 18 OCs). Analyses of mussel samples in 2011 from sites with the limited anthropogenic pollution shores have shown the occurrence of 11 pollutants (6 PAHs, 5 OCs), while in the samples from sites with intensive activity and expected pollution, 12 PAHs and 6 OCs were detected. Biochemical and biological responses studied only in mussels samples from the sites with the highest contamination showed a situation that was under strong seasonal influence. The intensity of the response was also influenced by deployment duration. Noteworthy correlations were detected among biochemical/biological effects and between mussel body burden and these effects. Continuous monitoring of priority pollutants of East Mediterranean Sea is vital both for ecological and human risk assessment purposes.

Polycyclic aromatic hydrocarbons (PAHs) are broad environmental contaminants which due to their lipophilic profile tend to be absorbed on particles and finally accumulate in marine environments. Analysis of PAHs is conducted in various commodities, such as water, sediment and in organisms, with bivalves possessing a predominant role due to their cumulative for organic contaminants and PAHs profile. Substantial research has been performed on the effects of PAHs pollution on the bioindicator itself, the marine bivalve, in matters of subcellular, cellular, tissue or organ alterations. Taking into account the persistence of these compounds, their ubiquity and the variety of health effects they may elicit to invertebrates, it is imperative to focus on biomarkers assessment after acute or subchronic exposure to PAHs. Nowadays, a tiered approach in Mussel Watch Programs is followed with chemical analysis of PAHs in mussel tissues being accompanied by detection of effects at subcellular, cellular, tissue, organ or organism level. This combined methodology serves on a number of levels-it measures with precision current PAHs pollution status and it links this pollution to possible health effects on bivalve populations This review aspires to consolidate knowledge on PAHs analysis and the biological effects that they elicit in bivalves. In this context, it is provided an overview on PAHs pollution as monitored with the use of bivalves. Specific focus is given on: (1) PAHs analytical methodologies and their performance (2) levels of marine PAHs as measured through bivalves within the last decade; current pollution status and (3) health effects of PAHs on bivalves as shown from field studies and laboratory experiments.

A battery of ecotoxicological assays of different trophic chain levels has been performed for water and sediment samples of two Greek vulnerable freshwater ecosystems (Karla Lake in Thessaly Region and Koronia Lake in Central Macedonia Region, respectively). These lakes, despite remediation programs, are still characterized by varied water quality. Furthermore, the quality of aquatic reservoirs aimed for human consumption as well as this of treated and untreated wastewater samples was also assessed through these bioassays. The outcome of the present research shows that condition of the studied lake ecosystems is still poor and intervention is needed for rectification of their continuous decline. Samples from treated municipal wastewater from the same regions were of medium to satisfactory quality, as measured by ecotoxicological assays. Despite causative relationships between burdened physicochemical parameters and increased toxicity, this toxicity could not always be attributed to these parameters. Results of bioassays in combination with standard physicochemical measurements of water samples may aid the integrated assessment of environmental risk arising from presence or release of these water samples in the ecosystem.

Chios mastic gum (CMG), a resin derived from Pistacia lentiscus var. chia, is known since ancient times for its pharmacological activities. CYP1A1 and CYP1A2 enzymes are among the most involved in the biotransformation of chemicals and the metabolic activation of pro-carcinogens. Previous studies referring to the modulation of these enzymes by CMG have revealed findings of unclear biological and toxicological significance. For this purpose, the modulation of CYP1A1 and CYP1A2 enzymes in the liver of male Wistar rats following oral administration of CMG extract (CMGE), at the levels of mRNA and CYP1A1 enzyme activity, was compared to respective enzyme modulation following oral administration of a well-known bioactive natural product, caffeine, as control compound known to involve hepatic enzymes in its metabolism. mRNA levels of Cyp1a1 and Cyp1a2 were measured by reverse transcription real-time polymerase chain reaction and their relative quantification was calculated. CYP1A1 enzyme induction was measured through the activity of ethoxyresorufin-O-deethylase (EROD). The results indicated that administration of CMGE at the recommended pharmaceutical dose does not induce significant transcriptional modulation of Cyp1a1/2 and subsequent enzyme activity induction of CYP1A1 while effects of the same order of magnitude were observed in the same test system following the administration of caffeine at the mean daily consumed levels. The outcome of this study further confirms the lack of any toxicological or biological significance of the specific findings on liver following the administration of CMGE.
