We also assessed the robustness of the associations in single organochlorine
Exposure to organochlorine
residues from past applications can become chronic for human health [3, 4].
Okoumassoun LE, Brochu C, Deblois C, Apkonan S, Marion M, Averill-Bates D and F Denizeau Vitellogenin in tilapia male fishes exposed to organochlorine
pesticides in Oueme River in Republic of Benin.
Occurrence of PCBs, organochlorine
insecticides, tris (4-chlorophenyl) methane and tris (4-chlorophenyl) methanol in human breast milk collected from Cambodia.
chemicals in seafood: occurrence and health concerns.
Other chemical compounds detected in drinking water and as dangerous to the health as organochlorine
pesticides are trihalomethanes (THM).
The analytical quality-control scheme included periodic analyses of organochlorine
standard mixtures and ultrapure water along with the samples.
Once extracts were obtained (sediments/ organisms) they were purified through adsorption chromatography in a column packed with florisil and anhydrous sodium sulfate previously purified, activated and deactivated to separate the polychlorinated biphenyls (PCB, Fraction 1) from the organochlorine
pesticides (OP, Fraction 2).
Concern about PCB, mercury and dioxin concentrations in the Great Lakes contributes to ongoing sport fish consumption warnings even though organochlorine
levels are generally declining.
Seventeenaswordfish samples from the Italian coast were tested for 28 man-made chemicals: organochlorine
chemicals (DDT and HCB), perfluorinated compounds (PFOS and PFOA, used in the production of textiles, food packaging and non-stick coatings) and brominated flame retardants (19 types of PBDE).
Prof Howard said: "For humans the main source of organochlorine
exposure is from diet, primarily through meat and dairy products.
In Silent Spring (Mariner), she documented how long-lived organochlorine
pesticides, most notoriously DDT, were not only ridding croplands of insects, streets of mosquitoes, and homes of spiders but also exacting a high toll on songbirds and other nontargeted species.
