Extension of a liquid chromatographic method for N-methylcarbamate pesticides in cattle, swine, and poultry liver.
Liver samples of bovine, swine, and poultry were fortified with 0, 5, 10, and 20 ppb mixed standards of an additional 6 carbamates as part of a method extension study. Each of the 3 species in this study was analyzed 4 times at 0, 5, 10, and 20 ppb fortification levels. The average of 12 recoveries of 6 carbamates at all 3 fortification levels was greater than 90%, with a maximum coefficient of variation less than 18%.
