A quantitative study is presented on linande and endosulfan residues in maize and cowpea ecosystems respectively. Both pesticides were found to dissipate very fast under the tropical Ghanaian conditions. The high rate of dissipation in leaves is attributed to the fact that the leaves were exposed to sunshine and wind leading to increased volatilisation. Endosulfan was found to dissipate faster from the cowpea ecosystem than lindane did in the maize ecosystem. The mean residue levels of lindane in maize grains were 0.02 μg g-1; whilst residue levels of endosulfan in cowpea seeds were 0.05 μg g-1. These levels are lower than the maximum residue limits recognized as acceptable by the Codex Alimentarus Commission. (author). 11 refs, 7 tabs
