Contamination of Fish and Sediments from the Vistula River by Organochlorine Pesticides and PCBs
The aim of our study was to assess the occurrence and to determine the concentrations of organochlorine pesticides and indicator PCB congeners in muscle tissue of freshwater fish species and, additionally, in sediments collected from three sampling sites of the Vistula River in the vicinity of Cracow. The determinations of HCH isomers, HCB, DDTs (p,p'-DDE, p,p'-DDD, o,p'-DDT and p,p'-DDT), and ...

متن کاملOrganochlorine pesticides in gallstones.
A method is described for the determination of organochlorine pesticide residues in human gallstones. The difficulty caused by the presence of large amounts of cholesterol in the stones is overcome by an acetylation step in the “clean-up” procedure, and the method finishes with identification and determination of the individual pesticides by gas-liquid chromatography. Results are given for 28 s...
متن کاملWhat Are Organochlorine Pesticides?

Pesticides are inherently toxic and often associated with adverse health effects in non-target organisms.1 Organochlorine pesticides are a large class of multipurpose chlorinated hydro...
متن کاملMonitoring of organochlorine pesticides using PFU systems in Yunnan lakes and rivers, China.
Polyurethane foam unit (PFU) systems were collected from 11 lakes and three rivers in the Yunnan Plateau, China and, the PFU extrusion liquids were analyzed for organochlorine pesticides (OCPs) by gas chromatography with electron capture detection (GC-ECD). The concentrations of pp'-DDE, HCB and HCHs were undetectable to 1.86 microgl-1 (mean 0.27 microgl-1), undetectable to 0.72 microgl-1 (mean...
