Environmental Risks of Pesticide Residues in the Lake Tana Sub-basin, Ethiopia: A Review.

ABSTRACT: Lake Tana, Ethiopia's largest natural lake and the headwater of the Blue Nile, provides critical ecosystem services and socio-economic benefits.

This systematic review synthesi zes information on agricultural pesticide use, their residues in fish, water, and sediments, and the associated ecological and human health risks.
