| Popis: | This work is done with the purpose ofdetermining residual concentration of organophosphorus pesticide (Chlorpyrifos)in vegetables (Okra, potato), surface water and ground water. Five samples ofeach vegetable, ground water and surface water were collected randomly fromeight union councils (UCs) of tehsil Mehrabpur district Naushahro Feroze.Pesticide residues were extracted and cleaned up using standard analyticalmethods USEPA 3510C and USEPA 3620C, respectively. In continuation to thissamples were analyzed through Gas Chromatography-Flame Ionization detector(GC-FID). Results showed that the residual concentration of selected pesticidewas not more than maximum residual limit (MRL) in ground water samples, maximumvalue 16µg/L was found in UC5 while minimum was 3µg/L in UC2. Whereas, insurface water higher residual concentrations were observed having maximum andminimum values 91.2µg/L and 25µg/L, respectively. However, in vegetable samples15% of okra and 20% of potato samples contained residual concentration withinMRL values and rest were found with higher concentrations. The presence of suchhazardous pesticides in vegetables is a serious threat to humans relying onthem for food. Therefore, it is very much necessary to regulate the use ofhazardous pesticides in recommended areas by conducting ongoing monitoring. |
