Large-scale studies are essential to assess the emission patterns and spatial distribution of organohalogenated pollutants (OHPs) in the environment. Bird eggs have several advantages compared to other environmental media which have previously been used to map the distribution of OHPs. In this study, large-scale geographical variation in the occurrence of OHPs, such as polychlorinated biphenyls...
Most organochlorine pesticides (OCPs) which are increasingly used in agriculture and industry are not biodegradable and thereby persist in the environment for a very long period of time. They are capable of negatively impacting the health of humans and biota when present in a higher concentration than recommended. This study evaluated the concentrations of 17 OCPs in surface water samples colle...
The Arctic has been contaminated by legacy organochlorine pesticides (OCPs) and currently used pesticides (CUPs) through atmospheric transport and oceanic currents. Here we report the time trends and air-water exchange of OCPs and CUPs from research expeditions conducted between 1993 and 2013. Compounds determined in both air and water were trans- and cis-chlordanes (TC, CC), trans- and cis-non...
The status of organic pollution in groundwater in eastern China along the Grand Canal from Hangzhou to Beijing was evaluated. Forty-two semi-volatile organic contaminants were analyzed, including 16 polycyclic aromatic hydrocarbons (PAHs), seven polychlorinated biphenyls (PCBs), 12 organochlorine pesticides (OCPs) and seven organophosphorus pesticides (OPPs). Among the detected contaminants, PA...
The health of aquatic organisms can be affected due to anthropogenic activities and limited actions reduce the pollution Black Sea. accumulation organic pollutants (OPs) in environment occurs water, sediment, then biota. turbot (Scophthalmus maeoticus) is a benthic fish commercial interest scarcely studied Sea region, none studies researched OP concentrations its main tissues. In this paper, po...
The study aimed at investigating the concentrations and geographical patterns of 11 polychlorinated biphenyls (PCBs) 15 organochlorine pesticides (OCPs) in reindeer muscle samples (n = 100) collected from 10 grazing districts Norway, 2009. Concentrations were examined for related to region as well age sex animals. measured PCBs OCPs meat generally low. Geographical revealed with previous mining...
