Now, we have something called fipronil that is as deadly to termites as chlordane
and heptachlor but not as risky to humans.
Consumption advice is triggered by PCBs (MN, WI, IL, and MO), mercury (MN, WI, MO, and TN), chlordane
(MO and TN), and perfluorooctane sulfonate (PFOS--WI and MN) (Figure 1).
Nearly all the air samples contained lindane and chlordane
products, and the pesticides with the highest mean concentrations were dieldrin and DDE.
was an insecticide that was used on corn, citrus, and vegetables and as a termiticde in homes.
Cluster groups 3 and 4 sediments typically contained elevated Cu, Hg, Pb, Zn, and Sb concentrations, whereas cluster group 3 sites also were distinguished by elevated LPAH, HPAH, PCB, and chlordane
During the period, the GEF also helped China reduce its output of these POPs by working to permanently close the country's largest chlordane
and mirex plant, which had a production capacity of 500 metric tons of chlordane
and 250 metric tons of mirex.
NARAPs have been developed for six substances (DDT, chlordane
, PCBs, mercury, dioxins/furans, and hexachlorobenzene).
, developed after bugs developed a resistance to DDT, is composed of over 50 different chemicals.
Ovary length diminished with increasing PCB and chlordane
concentrations, and ovary weight decreased with increasing PBDEs, the team reports an upcoming issue of Environmental Science & Technology.
They show that ministers this week (Tues) ordered that aldrin, chlordane
, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene, polychlorinated biphenyls (PCB), DDT, chlordecone, the sum of alpha, beta- and gamma-HCH, and hexabromobiphenyl be present in wastes at concentrations not exceeding 50 mg/kg.
They are subjected to strict controls under the Stockholm Convention which forbids or limits the production, use and marketing of twelve POPs: DDT, aldrin, dieldrin, endrin, chlordane
, heptachlor, hexachlorobenzene, mirex, toxaphene, polychlorinated biphenyls, dioxins, and furans was transposed into European Community law by Regulation 850/2004EC.
But, it added, a limited number of samples showed high concentrations of, among other things, arsenic, hydrocarbons, chlordane
, dieldrin, aldrin and lead.
