Includes bibliographical references (page 7). "The microwave energy produced by high intensity microwave oven, was used to extract pesticides from sediment samples. This system was compared with Soxhlet, sonification and convection heat extraction techniques. Sediment moisture and type of organic matter content are critical parameters in affecting the degree of recovery. Extraction procedure using a 30 second period repeated in sequence 5 times provided generally better recovery values than did 8 hours of Soxhlet extraction"--Abstract.
