Method 74


This method describes the sample collection and analysis of aldicarb (temik). Samples are collected by drawing known volumes of air through OSHA Versatile Samplers containing a glass fiber filter and two sections of XAD-2 adsorbent (OVS-2). Samples are extracted/desorbed with ace tone and analyzed by GC using a nitrogen/phosphorus detector.
