Abstract:

Organochlorines (OCs) are common environmental pollutants that have been linked to cancer. This work aims to assess the role of OCs as a risk factor for breast cancer and to evaluate the cellular changes induced by exposure to such environmental contaminants. The study included 70 cancer patients subjected to thorough history taking and routine investigations. Samples from tumor and normal adjacent tissue were taken to measure OCs’ levels and to perform molecular analysis (some oncogenic and apoptotic markers) by flow cytometry. There were significantly higher concentrations of methoxychlor, d

Abstract:

Antarctic penguins constitute excellent indicators of organic pollutants (PCBs, DDTs and HCHs), which reach the Antarctic either by atmospheric or maritime transport and are concentrated through the food chains. They are found mainly in lipids, both in adipose and other tissues of the organisms. Tissue samples of four gentoo and one Adélie penguins were collected during the summers of 1991, 1992 and 1993. PCBs and organochlorine pesticides (OCPs) were analysed in the adipose tissue, uropygeal gland, blood, brain, muscle, bone and liver. Organochlorines (OCs) were detected in the majority of th

Abstract:

A multiresidue method for the simultaneous determination of 22 organochlorine (OCs) and organophosphorus (Ops) pesticides (including isomers and metabolites), representing a wide range of physicochemical properties, was developed in fatty matrices extracted from meat. Pesticides were extracted from samples with acetonitrile/n-hexane (v :v, 1:1). The analytical screening was performed by gas chromatography coupled with electron-capture detection (ECD). The identification of compounds was based on their retention time and on comparison of the primary and secondary ions. The optimized method was

Abstract:

Abstract Organochlorines (OCs) are persistent pesticides that remain in the environment and body for extended periods after exposure. Little is known about their long-term impact on cognition in later life. Some studies, but not all, have shown that higher levels of selected OCs are associated with lower cognitive function (CF). Using weighted linear generalized estimating equations, we explored whether the association between lipid-adjusted levels of 8 OCs and global CF is modified by race/ethnicity in 985 adults age 60+ from the National Health and Nutrition Examination Surveys (2011-2014).

Despite the ban on the use of organochlorine compounds (OCs), they are still widely distributed in various components of the Black Sea ecosystem, including fish. Sevastopol marine area, as a region of active economic use, is a subject of significant anthropogenic impact. The levels of OCs contamination in the scorpion fish Scorpaena porcus Linnaeus, 1758, which leads a sedentary life, can serve as an indicator of such impact. The organochlorine compounds were determined in 58 samples of white muscles, gonads and liver of the scorpion fish captured in 2016–2017 in the various bays of Sevastopol

OCI residues were not detected in drinking water originating from great distributive systems in Vojvodina (purified and conditioned water) but in some sub-artesian wells there were HCH and aldrin residues. OCI residues were quantified in surface water of the river Danube which is in the required group, except for H

Abstract:

Soil organic matter (SOM) and its heterogeneous nature constitutes the main factor determining the fate and transformation of organic chemicals (OCs). Thus, the aim of thus research was to analyze the influence of the molecular chemodiversity of a stable SOM (S-SOM) on the sorption potential of different groups of OCs (organochloride pesticides—OCPs, and non-chlorinated pesticides—NCPs, polycyclic aromatic hydrocarbons—PAHs). The research was conducted as a batch experiment. For this purpose, a S-SOM was separated from six soils (TOC = 15.0–58.7 gkg−1; TN = 1.4–6.6 gkg−1, pH in KCl = 6.4–7.4 a

There are mainly three groups of synthetic organic pesticides-organochlorines, organophosphates and carbamates. Fishes are the major vulnerable biotic components as they sequester the effects to higher organisms including man through food chain.
