Objective: This retrospective descriptive study aimed to investigate organochlorine compounds in women who breastfeed and work as a seasonal agricultural worker (SAW).
Methods: It was carried out on 100 woman working as SAW. Data were collected with a questionnaire by face-to-face interview and analyzed the residues of 27 items of organochlorine pesticides, dichlorodiphenyltrichloroethane (DDT) metabolites and polychlorinated biphenyls, from persistent organic pollutants in mothers' 50 mL breast milk. Descriptive statistics, Chi-square test, and correlation analysis were used to evaluate data.
Results: Polychlorinated biphenyl (PCB)28 component was determined in almost all women's milk and more than half of collected milk contained beta-hexachlorocyclohexane (HCH), PCB52, pp'-dichlorodiphenyldichloroethylene (DDE), hexachlorobenzene (HCB), PCB70, pp'- dichlorodiphenyltrichloroethane (DDT) ve Gamma HCH, respectively.
Conclusion: It was recommended that necessary legal regulations and public information policy about that subject should exist.

The persistence and ecological impact of per- and poly-fluoroalkyl substances (PFAS) in water sources necessitate effective and energy-efficient treatment solutions. This study introduces a novel approach using cerium dioxide (CeO) electrodes enhanced with oxygen vacancy (O) to catalyze the defluorination of PFAS. By leveraging the unique affinity between cerium and fluorine-containing species, our approach enables adsorptive preconcentration and catalytic degradation at low oxidation potentials (1.

The present review provides the first analysis and synthesis of the available scientific information on the effects of anthropogenic contaminants on cephalopod embryos, paralarvae, and juveniles. We evaluated 46 articles published between 1970 and 2023 that focused on trace elements (69%), pharmaceutical compounds (11%), persistent organic compounds (11%), and plastics (9%). To date, the greatest scientific effort has originated from Europe and Asia (France [57%], China [9%], Italy [7%], and Spain [4%]), with few reports available from the rest of the world.

Microbe-mediated remediation becomes a desire method for removal of persistent organic pollutants (POPs) due to its eco-friendly and sustainable nature. The improvement of practical feasibility requires constructing comprehensive species pool, while it is still limited by the rapid recognition of potential bacterial resources from environment. Here, based on the relative abundances of bacterial OTUs and pollutant concentrations, we established indexes to assess their tolerance to organochlorine pesticides (OCPs) and flame retardants (FRs) that are atmospheric transported and naturally accumulated in forest soil via forest filter effect.

Perfluorooctanoic acid (PFOA), an anthropogenic organic pollutant known for its persistence, resistance to degradation, and toxicity, has raised significant concerns about its potential ecological impacts. Zostera marina, a common submerged seagrass species in temperate offshore areas, is highly vulnerable to pollutant stressors. However, the impact of PFOA on Z.

Addressing the global challenge of ensuring access to safe drinking water, especially in developing countries, demands cost-effective, eco-friendly, and readily available technologies. The persistence, toxicity, and bioaccumulation potential of organic pollutants arising from various human activities pose substantial hurdles. While high-performance liquid chromatography coupled with high-resolution mass spectrometry (HPLC-HRMS) is a widely utilized technique for identifying pollutants in water, the multitude of structures for a single elemental composition complicates structural identification.
