dc.description.abstractThe study was organized to evaluate the extent of accumulation of chlorpyrifos on Lactuca sativa during cultivation and also examine the effect some pre-household treatment procedure on residue levels. Concentrations of Chlorpyrifos applied at different stages of growth of lettuce were examined using GC equipped with LCD. at different time intervals of 1 h 24 h and 7 days after pesticide application. The results showed that residue levels detected at 1 h and 24 h after application were all above the MRL of 0.05 mgkg-1 and can pose health risk to consumers while that recorded 7 days after application were far below the MRL. Accumulation of chlorpyrifos on crop during cultivation was not observed since no significant differences were observed 7 days after application at all the different stages. There is therefore the need for farmers to allowed 7 days’ re-entry intervals before harvesting. All the pre-household treatment procedures caused significant reduction in residues levels. Treatment T3 was most effective in removing residues. Hence to reduce the risk associated with intake of chlorpyrifos through lettuce, T3 procedure should be followed before consumption.en_US
