Organochlorine Pesticides in Antarctica
Nature, 1967The first reports of organochlorine pesticides in wildlife in the vicinity of the US Antarctic base at McMurdo Sound suggested that local human activity might be responsible. Measurements of samples from the British Antarctic Survey Base at Signy Island in the South Orkneys now suggest that there is a world-wide pattern of distribution by means of the ...

Organochlorine pesticide residues in Songkla Lake
Environmental Monitoring and Assessment, 1994The water quality of Songkla Lake for organochlorine (OC) pesticide contamination was studied from chosen sampling sites (stations) using the lakes geographic data and pollution sources. The water samples were collected monthly from 13 stations in Songkla Lake during September 1991-November 1992.

Biodegradation of Organochlorine Pesticides
2015The widespread use of organochlorine pesticides (OCPs), mainly in the past, has caused serious environmental problems. Many OCPs were recently categorized as persistent organic pollutants (POPs) that should be controlled as toxic environmental contaminants.

Concentration of organochlorine pesticides in wine corks
Chemosphere, 2001Wine corks were extracted and analyzed for 23 organochlorine pesticides, including alpha-, beta-, and gamma-hexachlorocyclohexanes (HCH), hexachlorobenzene, DDT, DDE and DDD, chlordane, endosulfan, dieldrin, aldrin, and endrin. This was done to investigate the occurrence, concentrations, composition profiles, and possible sources of organochlorine ...

Temporal Bioavailability of Organochlorine Pesticides and PCBs
Environmental Science & Technology, 2006Because PCBs and organochlorine pesticides continue to be of global concern, studies that address information gaps, such as factors and influences of spatial and temporal effects on contaminant bioavailability, are valuable. The present study focused on the spatial and temporal distribution of bioavailable organochlorine pesticides and PCBs in surface ...

Persistent organochlorine pesticides in Mexican butter
Food Additives and Contaminants, 2003Organochlorine pesticides have been used in Mexico in malaria control programmes against ectoparasites and as seed dresser. Owing to their chemical stability, they tend to accumulate in the lipid part of the organisms. The stored pesticides are excreted with the endogenous fat during milk production.

Atmospheric burden of organochlorine pesticides in Ghana
Chemosphere, 2014Organochlorine pesticides (OCPs) are subject to the Stockholm Convention on POPs and have been banned or restricted globally. In Ghana, concerns of illicit applications of some OCPs have been raised in recent times. Applying polyurethane foam (PUF) disk passive air samplers (PAS), the levels of OCPs in the atmosphere and their spatial resolution were ...

The neurotoxicity of organochlorine and pyrethroid pesticides
2015Organochlorine and pyrethroid compounds represent an old and a new class, respectively, of insecticides. Organochlorines such as DDT, dieldrin, or chlordecone, have been banned, primarily because of environmental issues. DDT is still used in certain countries to fight malaria-bearing mosquitoes, while lindane still finds some limited used against head ...

Organochlorine Pesticide Residues in Bovine Milk
Bulletin of Environmental Contamination and Toxicology, 2007Monitoring of bovine milk of different places in Bundelkhand region of India was carried out to evaluate the status of organochlorine pesticide (OCP) residues. Out of a total of 325 samples 206 (63.38%) were contaminated with residues of different OCPs. The average concentration of total HCH was 0.162 mg/kg.

Organochlorine Pesticides in Rainwater in the British Isles
Nature, 1968PREVIOUS studies of the presence of the persistent organochlorine pesticides in the atmospheric environment of this country1–3 have all indicated the need for more comprehensive surveys. The first of these studies by Wheatley and Hardman1 was confined to rainwater collected in the rural area of Wellesbourne, in Warwickshire.
