Blood samples were collected from field workers involved in pesticide spraying activities at three different farms in Tahsil Mailsi, District Vehari (Punjab), Pakistan. Twenty seven villagers (including three controls), ranging from 16 to 50 years of age and one to nine years of pesticide application experience were tested. The blood samples were analyzed for 383 different pesticides using Gas Chromatograph Mass Spectrometer (GC-MS) multi residue analytical technique. Only chlorpyrifos (0.009 mg/l) and pyributicarb (0.001 mg/l) were detected in the blood samples.

Key words: Multi-pesticide residues, blood sample, GC-MS.
