Persistent chlorinated pesticides in air, water, and precipitation from the Lake Malawi Area, Southern Africa

Article Abstract:

The pesticides in the air and lake surface in Senga Bay on the southwest side of Lake Malawi in southeast Africa were compared to those in the Laurentian Great Lakes and Lake Baikal. Comparison of the data with that of temperate and arctic regions suggests the tropical regions may be a global source and sink for chlorinated pesticides.

Biomagnification of DDT through the Benthic and Pelagic food webs of Lake Malawi, East Africa: importance of trophic level and carbon source

Article Abstract:

DDT biomagnification accumulation occurs more extensively in pelagic food webs compared to benthic organisms according to analysis of fish species found in Lake Malawi of East Africa. Accompaning graphs and illustrations provide additional statistical data.

Spatial trends and historical deposition of polychlorinated biphenyls in Canadian midlatitude and Arctic lake sediments

Article Abstract:

The distribution and concentration of polychlorinated biphenyls (PCB) in Arctic and midlatitude Canadian terrestrial sites were analyzed by utilizing sediment core samples from nine lakes Canadian and Artic lakes. Samples from the Amituk and Ste Therese Lakes of Canada exhibited high sedimentation rates. The total concentrations of PCB was detected in sediments samples from the high Arctic lakes compared to sediment samples from the sub-Arctic lakes.
