Abstract
A simple, rapid, and reproducible method which essentially involves filtration, rather than centrifugation, as in the conventional method, for a soil-pesticide solution system uses a hypodermic syringe fitted with a filter paper disc and permits quantification of parathion and γ BHC sorbed at extremely short time intervals down to 5 sec.
