Concentrations of chlorinated pesticides were analyzed in air (biweekly 1997−1998), water, and precipitation at Lake Malawi, in southeast Africa. The pesticides in air in Senga Bay on the southwest shore of Lake Malawi were not extensively weathere

A study of PCB concentrations and fluxes in lake sediments was conducted to test the “global fractionation” hypothesis that deposition of semivolatile organics will decline while more volatile congeners will be enriched in polar regions. Sediment

The Arctic is generally considered to be a pristine environment and has few direct inputs of organochlorine compounds (OCs), including pesticides, herbicides, polychlorinated biphenyls, or polycyclic aromatic hydrocarbons (PAHs). In spite of this, ai

Chlorobornanes (CHBs) were isolated from recent and older sediments as well as from rainbow trout muscle in two prairie lakes that were treated with toxaphene as a pesticide in the early 1960s. Cored sediments representing the years of treatment (196

Sediment cores were collected from eight remote lakes in Canada, along a mid-continental transect from 49°N to 82°N, with the objective of examining latitudinal and temporal differences in deposition of a wide range of persistent, semi-volatile, or

The lack of information on seasonal variation of toxaphene (polychlorobornanes) in the arctic atmosphere has prompted a study in the Canadian north. Using high volume impactors with a 10 μm diameter size-selective inlet for particles and a collectio

From July 1988 to September 1989, 143 air samples, obtained at Egbert, ON, Canada, were analyzed for vapor-phase polychlorinated biphenyls (PCBs) and organohalogen pesticides. This data set is believed to be the first high temporal resolution PCB dat

Uptake, clearance and extent of metabolism of 14C-labelled t-butylphenyldiphenyl phosphate (t-BPDP), tri-m-cresyl phosphate (mTCP), tri-p-cresyl phosphate (pTCP) and triphenyl phosphate (TPP) were studied in rainbow trout ( Salmo gairdneri ) and fath
