Honey is considered to be a health-promoting food product. Therefore, it is assumed that it should be free of contaminants. Although the use of organochlorine pesticides (OCPs) was banned a few decades ago in developed countries, persistent organic pollutants (POPs) are still detected in various environmental and biological matrices, including food. These contaminants exhibit toxic properties and bioaccumulate in some food chains. The validation of a modified QuEChERS extraction method was successfully performed for o,p’-DDT, o,p’-DDE, o,p’-DDD, p,p’-DDT, p,p’-DDE, p,p’-DDD, heptachlor and dieldrin. 2,2′,4,4′,5,5′-hexachlorobiphenyl (PCB 153) was used as an internal standard. The modification involved changing the solvent from acetonitrile to n-hexane after extraction. Quantitation was carried out using gas chromatography with an electron capture detector (µECD). The mean recovery values for o,p’-DDT, o,p’-DDE, o,p’-DDD, p,p’-DDT, p,p’-DDE, p,p’-DDD and dieldrin, spiked at 2.9 ng/g and 20 ng/g, ranged from 64.7% to 129.3%, and, for heptachlor spiked at 5.6 ng/g and 20 ng/g, ranged from 68.0% to 88.3%. The relative standard deviation (RSD) for these concentrations did not exceed 20%, and the within-laboratory reproducibility was below 20%, except o,p’-DDE and p,p’-DDT, which were 25.2% and 20.7%, respectively. This modified QuEChERS extraction method for selected organochlorine compounds was demonstrated as effective for routine testing in honey.

Furan and its derivatives are found in various heat-treated foods. Furan is classified as a possible human carcinogen. The European Union authorities recommend collecting data on the occurrence of these compounds, estimating consumer exposure, and taking measures to protect human health based on a scientific risk assessment. The aim of this study was to estimate the exposure of infants and toddlers to furan and its methyl derivatives—2-methylfuran, 3-methylfuran, and ∑2,5-dimethylfuran/2-ethylfuran—present in home-prepared foods and to characterize the associated health risks. The compounds of interest were determined using the HS-GC/MS. The risk was characterized by the calculation of the margin of exposure (MoE). Levels of furan and its derivatives in analyzed samples were in the range of <LOD ÷ 10 µg/kg and <LOD ÷ 80.3 µg/kg, respectively. The MoEs for neoplastic effects in most of the presumed scenarios indicate a risk associated with the intake of analyzed compounds in both age groups (MoE < 10,000; 331 to 6354 for 95th percentile, 3181–39,033 for median). The MoEs for non-neoplastic effects indicate a potential risk associated with the intake of 3-methylfuran and Σ2,5-dimethylfuran/2-ethylfuran for high exposure (95th percentile) only (MoE < 100; 16–47). The obtained results indicate the need for further research in this area.

Endocrine-disrupting chemicals (EDCs), including substances used in plant protection products (PPPs), are a source of ongoing concern for the EU society. Under the EC Regulation 1107/2009, the endocrine-disrupting (ED) properties of active substances, safeners, and synergists used in PPPs shall be investigated. The scientific criteria established by the Regulation (EU) 2018/605 and the joint guidance of the European Chemicals Agency (ECHA)/European Food Safety Authority (EFSA) provide the basis for this assessment. Data requirements for the approval of safeners and synergists have been recently published in Commission Regulation (EU) 2024/1487, allowing a consistent assessment of these substances. The approach to assessing co-formulant hazards is currently a subject of EU-wide discussion. It outlines the necessity to take into account information or evaluation data from other than pesticides' EU regulatory frameworks, such as REACH or SCCS applications for cosmetic ingredients. This paper outlines: a) current EU approach applied for identification of endocrine disrupting properties of pesticides; b) issues related to European regulations that may have an indirect impact on the safe use of plant protection products and c) an analysis of the European Commission's activities aimed to limit exposure to EDCs associated with use of PPPs in the society.

Introduction and objective: Polybrominated diphenyl ethers (PBDEs) are a class of flame-retarding synthetic compounds. They may cause a potential threat to human health due to their bio-accumulative and toxicological properties, and ubiquitous presence in the environment. Food, and ingested...

The study aimed to determine the levels of selected polybrominated diphenyl ethers (PBDEs) in human milk and characterize the risk for breastfed infants using EFSA and U.S. EPA methodologies. The predominant PBDEs for which EFSA and U.S. EPA established toxicological reference values have been selected for evaluation. Concentrations of BDE-47, BDE-99 and BDE-153 were determined in breast milk samples from 25 mothers living in Poland. The estimated daily intakes of PBDEs for breastfed infants were calculated based on the results of PBDE concentrations obtained for each case and for the mean concentrations of the analyzed compounds. The estimated infants' daily intake of PBDEs from human milk was below U.S. EPA RfD, therefore not considered a health risk. In calculations according to approach applying MOEs (EFSA), we indicated a potential health concern with respect to exposure of infants to BDE-99. The calculated results based on the available methodologies do not provide clear information for the purposes of consumer safety assessment regarding exposure to the BDE-99 congener. Present study indicates the necessity to develop an internationally harmonized strategy for assessing the risk posed by polybrominated diphenyl ethers, especially for breast-fed infants.

Polybrominated diphenyl ethers (PBDEs) have been used for many years as flame retardants. Due to their physicochemical and toxicological properties, they are considered to be persistent organic pollutants (POPs). BDE-209 is the main component of deca-BDE, the one PBDE commercial mixture currently approved for use in the European Union. The aim of this study was to analyse BDE-209 in surface soil samples from Warsaw and surrounding areas (Poland) as an indicator of environmental pollution with PBDEs, and to characterise the associated health risk. A total of 40 samples were analysed using gas chromatography with electron capture detection (GC-µECD). Concentrations of BDE-209 in soil ranged from 0.4 ng g⁻¹ d.w. (limit of quantification) to 158 ng g⁻¹ d.w. Overall, 52.5% of results were above the method’s limit of quantification. The highest levels were found at several locations with heavy traffic and in the vicinity of a CHP plant in the city. The lowest concentrations were observed in most of the samples collected from low industrialized or green areas (<0.4 to 1.68 ng g⁻¹ d.w.). Exposure to BDE-209 was estimated for one of the most sensitive populations, i.e., young children. The following exposure routes were selected: oral and dermal. No risk was found to young children’s health.
