The status of pesticide pollution in Tanzania.

The paper summarises the findings of recent studies carried out to assess the levels of pesticide residues in water, sediment, soil and some biota collected from different parts of Tanzania. Although the intention is to cover the whole country, so far the studies have focused on areas with known large-scale pesticide use (Southern Lake Victoria and its basin, TPC sugar Plantations in Kilimanjaro region, Dar es Salaam coast, Mahonda-Makoba basin in Zanzibar) and a former pesticide storage area at Vikuge Farm in Coast region). Analysis of the cleaned extracts in GC-ECD/NPD revealed the dominance of organochlorines in all samples.
