Atmospheric Transport and Air-Surface Exchange of Pesticides

Concentrations and potential health hazards of organochlorine pesticides in shallow groundwater of Taihu Lake region, China

“…Differences in composition of OCP isomers/metabolites in the environment can reveal different pollution sources (Doong et al, 2002;Zhou et al, 2006) and various ratios have been used to identify the sources of OCPs (Strandberg et al, 1998;Bidleman, 1999;Hong et al, 1999;Covaci and Hurab, 2001). However, the OCPs in groundwater are not derived from direct inputs and the ratios of OCP isomers/metabolites will change during transport due to differences in their physical and chemical properties.…”

African and Asian Dust: From Desert Soils to Coral Reefs

“…Long-range atmospheric transport and deposition of some persistent organochlorine pollutants (especially polychlorinated dibenzo-p-dioxin and furan [PCDD/Fs], PCBs, and some chlorinated insecticides like DDT, chlordane, and toxaphene), and of anthropogenic and biogenic aliphatic hydrocarbons (e.g., n-alkanes) and polycyclic aromatic hydrocarbons (PAHs), are well documented (e.g., van Pul et al 1999). Some studies have focused specifically on transport to the oceans (e.g., Simoneit et al 1988, Atlas and Schauffler 1990, Bidleman 1999, MacDonald et al 2000. Other persistent halogenated organic pollutants have recently been identified as important atmospherically transported persistent contaminants (see Lipnick et al 2001), including polychlorinated n-alkanes and naphthalenes, polybrominated diphenyl ethers (used as flame retardants), and perfluorinated chemicals (e.g., perfluorooctane sulfonate; Giesy and Kannan 2001).…”

The Kuril Islands as a Potential Region for Aquaculture: Organochlorine Pesticides in Pink and Chum Salmon

“…The same difference was observed for salmon from the Sea of Okhotsk. ∑HCHs, as compared to DDT, are subject to atmospheric transfer to a greater degree [24]; as a result, ∑HCHs is spread northward along the Asian coast and accumulates in the Arctic region [25][26][27].…”
