Abstract
Improper pesticide use in Agriculture in rural areas portends huge health hazard to humans and other biological life forms. This present study was aimed at screening four vegetables randomly sampled from selected farmlands in Wudil, Kano State of Nigeria for pesticide residues and their derivatives with intention of determining possible contamination from pesticides residues. The extraction was carried out by standard procedures and the identification and quantification of pesticide residues were carried out by GC-MS analysis. The result revealed chlorpyrifos (an organophosphorus) as the only known active pesticide residue detected in all four vegetables. The mean levels detected were 1.42, 1.69, 1.86 and 2.10mg/kg of sample for spinach, carrot, cabbage and garden egg, respectively. The levels of chlorpyrifos detected in all four vegetables were significantly higher (p<0.05) than the WHO/FAO Maximum residual limit (MRLs) of 0.5-1.0mg/kg of sample. Also detected were naphthalene and alkylbenzenes, volatile organic compounds described as co-formulants in pesticides. This result is indicative of risk and public health concerns. Sensitization of farmers on best practice as well as strict monitoring and regulation of pesticide use is still hugely desired.

Key words: Pesticides residues, GC-MS, vegetables, Organophosphorus, Chlorpyrifos.
