In this study, a new clean up method was developed for the routine multiresidue determination of organochlorine pesticide residues in honey. The analytical procedure requires sample extraction with methanol, followed by a clean up step through a C18 Sep-Pak cartridge. Finally, pesticides are eluted with hexane. The determination of organochlorine pesticide residues was performed by capillary ga...

National long-term monitoring programs on persistent organic pollutants (POPs) in background air have traditionally relied active sampling techniques. Due to limited spatial coverage of samplers, questions remain (i) whether sampler sites are representative for atmospheric burdens within the larger geographical area targeted by programs, and thus (ii) if main sources affecting POPs across a nat...

Atmospheric concentrations of organochlorine pesticides (OCPs) have been measured for the first time at Station Nord, North-East Greenland, from 2008 to 2010. The data obtained are reported here. Hexachlorobenzene (HCB), endosulfan I and hexachlorocyclohexanes (HCHs) were the predominant compounds detected in the atmosphere, followed by p,p'-DDE and dieldrin. Chlordane isomers and related compo...

Bimonthly bulk atmospheric deposition samples (precipitation + dry particle) were taken for one year at an arctic (Abisko, 68°20' N, 19°03' E) and a sub-arctic (Krycklan 64°14' N, 19°46' E) location in northern Sweden using Amberlite IRA-743 as an absorbent for hydrophobic pollutants. The samples were analyzed by gas chromatography-high resolution mass spectrometry (GC-HRMS) for polychlorinated...

The aim of this study was to determine the level of organochlorine pesticides in freshwater fish from the Zagreb area, Croatia. The study included 215 freshwater fish samples from three sites: the Sava River, Lake Jarun, and five fishponds from the Zagreb surroundings. Organochlorine pesticides DDT and derivates, HCH, HCB, lindane, aldrin, dieldrin, endrin, heptachlor with epoxide, and methoxyc...

The threat to wildlife from chemical exposure exists regardless of the presence conservation boundaries. An issue exacerbated by use environmentally persistent insecticides for vector control and long-range transport legacy organic pollutants. In this comparative study between two important regions in South Africa, Kruger National Park (KNP) Ndumo Game Reserve (NGR), we assessed organochlorine ...

BACKGROUND Chlorinated pesticides have been used in pest control for several decades in the world. These compounds are still applied in many regions, and their continuous usage has resulted in their bioaccumulation and residue in the food chain. These residues could transfer to food products and accumulate in fat tissues. Undoubtedly, the breast milk could be a significant biomarker for estimat...
