uses of dieldrin
were banned in the United States in 1985 .
This seems especially the case for dieldrin
that contributed most to the risk of pesticides found in bean leaves as can be seen from its high residue levels compared to the TDI (Table 4).
Overall, the majority of the bat samples had detectable concentrations of dieldrin
and DDE, while many samples also had detectable concentrations of DDT, DDD, heptachlor epoxide and diazinon (Figure 2).
Hille's research focused on the toxicity of chlorinated hydrocarbons, as dieldrin
, to fish; toxicity of surfactants, as detergents, to fish; stream macro-invertebrate community structure; and water quality criteria of streams.
This included the metals arsenic, lead and mercury, pesticides chlorpyrifos, permethrin and endosulfan, persistent organic pollutants dioxin, DDT, dieldrin
and chlordane and the food processing byproduct acrylamide.
All 364 children in the study (207 preschool children between two and seven and 157 school-age children between five and seven) exceeded cancer benchmarks for arsenic, dieldrin
, DDE and dioxins.
And--some good news--with the exception of dieldrin
, the half-life values measured for the pesticides in the samples indicated that legacy pesticide levels were decreasing over time in the Delmarva.
A preliminary note on a probable case of dieldrin
resistance in Anopheles culicifacies in Thana district, Bombay state.
Aldrin, Chlordane, Dieldrin
, Endrin, Heptachlor, H.
Organochlorine pesticides, such as DDTs and its metabolites (2,4' and 4,4'-DDT, DDD and DDE), hexachlorobenzene (HCB), cyclodienes (aldrin, dieldrin
, and endrin), chlordanes (heptachlor, heptachlor epoxide, cis-chlordane, transchlordane, cis-nonachlor, trans-nonachlor, and oxychlordane), HCHs ([alpha],[beta],[gamma],[delta]-isomers), mirex, and industrial chemicals like PCBs, are ubiquitous environmental pollutants (Kannan et al.
These included methomyl (18), ronnel (19), dieldrin
(20) and furadan (21).
Those chemicals included dieldrin
, DDT, polychlorinated biphenyls (PCBs), chlordane, and polycyclic aromatic hydrocarbons (PAH).
