Twenty-nine conifer needles in mountain-valley areas from the southeastern Tibet were collected with altitude span from 1520 to 4340m above sea level (m.a.s.l.). They were analyzed for organochlorine pesticides (OCPs), including hexachlorocyclohexanes (alpha-, beta-, gamma- and delta-HCH), dichlorodiphenyltrichloroethane (p,p'-DDE, p,p'-DDD, o,p'-DDT and p,p'-DDT) and hexachlorobenzene (HCB). C...

The study was aimed to determine the concentrations of organochlorine pesticides (OCPs) in bovine milk (both branded and unbranded) collected from in and around Tiruchirappalli city, Southern India. The results of the present investigation indicated that these milk specimens were found to be contaminated with 7 different pesticides. Mirex (higher incidence), Heptachlor, o,p’-DDD, o,p’DDE, Aldri...

Organic contaminants [polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenylethers (PBDEs), nonylphenols], organotin compounds and trace metals (cadmium, chromium, mercury and zinc) were determined in flounder (Platichthys flesus) liver and sediment from the Amsterdam harbour (North Sea Canal) and Rotterdam harbour (Euromonding) and off the Dutch coast betwe...

Levels of organochlorine pesticides (OCPs) were determined in dried cocoa beans obtained from cocoa produce stores at Ondo and Ile-Ife, Southwestern Nigeria. Cocoa beans samples were sun dried to a constant weight, pulverized and soxhlet extracted with dichloromethane to obtain the OCPs. Qualitative identification and quantitative evaluation of the extracted OCPs after clean-up on silica gel we...

This study used gas chromatograph-mass spectrometer (GC-MS) to determine three kinds of halogenated organic pollutants (HOPs) in the edible muscles nine fish species Laibin section Hongshui River Xijiang Pearl system. The results showed that sum organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) muscle was 8.94∼43.32 ng/g ww, 1.22∼4.09...

In this study, it was aimed to determine organochlorine pesticides (OCPs) in three types of milk (cow's, buffalo's, and sheep's milk) produced in Afyonkarahisar province of Turkey. The results indicated that these milk specimens were found to be contaminated by 21 different pesticides. Sixteen OCP residues were detected in sheep's milk and it was followed with 14 pesticides in buffalo's milk an...

Perfluorinated compounds (PFCs) and organochlorine pesticides (OCPs) were analyzed in surface soils along the Huaihe River. Sixteen target PFCs and nine OCPs were quantified in soils from a region of intensive industrial and agricultural development. Concentrations of PFCs and OCPs ranged from less than the limit of detection (LOD) to 1.22 ng/g and 3.63 to 227 ng/g, respectively. Contamination ...

Organochlorine pesticides (OCPs) are the potential group of chemicals used to improve agricultural productivity. The extensive use of pesticides to improve agricultural productivity played an important role in the last century. These compounds have been applied for decades in preventing, repelling or mitigating the effects of pests. OCPs are one of the most persistent organic pollutants present...

Organochlorine Pesticides (OCPs) such as DDT and HCH, have stable chemical properties and less biodegradability. As a kind of persistent organic pollutants, they have high risk to the environment and human health. Organochlorine pesticide have been used in Uttar Pradesh in agriculture as a seed dresser, in sanitation , in malaria control programme and in livestock to combat ectoparasites. The p...

Abstract A field survey was conducted in a contaminated industrial site of southern Beijing, China to investigate the contents and distribution of the organochlorine pesticides (alpha-, beta-, gamma-, delta-HCH, p,p'-DDT, p,p'-DDE, p,p'-DDD and o,p'-DDT) in the profiles of soil, and a health risk assessment was carried out with CalTOX multimedia exposure model. Results showed that mean concentr...
