Abstract
Residual concentrations of organochlorine pesticides in vegetables cause concern because of their
adverse health effects. Pesticides have been applied in agricultural production and vector control in
Uganda. Vegetables may absorb high residual levels of cyclodienes necessitating regular monitoring.
Carrots are commonly consumed in Uganda as raw salads or components of different dishes.
A gas chromatograph with electron capture detector was used to quantify organochlorine pesticides.
Pesticide residues were confirmed by gas chromatography with a mass spectrometer. Trace amounts
of 4,4′-dichlorodiphenyltrichloroethane (DDT), 2,4′-DDT, 2,4′-dichlorodiphenylchloroethane
(DDE), α- endosulphan, β-endosulphan, α-lindane, γ-lindane and dieldrin were detected in carrots.
Levels of organochlorine residues in carrots were below the maximum residue limits considered
safe for human consumption by Codex Alimentarius and the European Union Commission.
