A sensitive, inexpensive procedure has been developed for the rapid analysis of applicator exposure pads. The pads were extracted with methanol or ethanol, the pesticides were selectively adsorbed and eluted on a reversed-phase solid support (SEP-PAKs) (a concentration step of 50:1), and the elutate...
