PG - 519 LID - 10.1007/s10661-017-6226-6 [doi] AB - Assessment of levels of pesticide residues in vegetables was carried out in some villages in the Western Usambara and Uluguru Mountains of Tanzania where varieties of vegetables are grown. Tomatoes and cabbages were the most popular enterprise grown all year round and therefore were selected as the model crops for this study. Analysis of the cleaned sample extracts on a gas chromatography with electron capture detector (GC-ECD) and confirmation on the Gas chromatography-mass spectrometry (GC-MS) revealed dominance of organochlorine pesticides. Organophosphorous pesticides (parathion and marathion) were only detected in some samples, however, in most cases with higher concentrations compared to organochlorine pesticides. Levels of pesticide residues detected in vegetables were up to: parathion 5.07 mug/Kg, marathion 3.73 mug/Kg, alpha-endosulfan 0.32 mug/Kg, beta-endosulfan 0.53 mug/Kg, dieldrin 1.36 mug/Kg, gamma-HCH 0.25 mug/Kg, alpha-HCH 0.09 mug/Kg, and p, p'-DDT 0.64 mug/Kg. These results clearly show that vegetables are contaminated with different pesticide residues. However, the total levels of pesticide residues in both tomatoes and cabbages are lower than their respective codex alimentarius maximum residue levels (MRLs). This means that the vegetables produced in the area are suitable for human consumption. FAU - Mtashobya, Lewis A AU - Mtashobya LA AD - Mkwawa University College of Education, P.O.
