摘要：

In this study, residual concentrations of chlorpyrifos (CPF) were determined in feed (40) and fodder (25) samples collected from various locations of Tarai region of Uttarakhand. For extracting residues, liquid-liquid partition followed by alumina column clean up was used and the detection and quantification of residues was undertaken with the help of high-performance liquid chromatography using C18 column and diode array detector at 220 nm. Of the total 40 feed samples analyzed, 7 (17.5%) samples were found positive for CPF with the mean residual concentration of 0.058 mu g g(-1); while out of 25 fodder samples, CPF residues were detected in a single (4%) sample with residual concentration of 0.39 mu g g(-1). However, none of the feed or fodder samples contained CPF residues above the prescribed limit.
