The treatment of water, soil and food samples was tested with a modified equipment of glass for simultaneous steam distillation/solvent extraction. Spiked samples with 22 pesticides (most of them contained halogen) and PCB yielded good or very good recoveries after 1.5 h for water samples and after 5 h for soil and plant food samples, respectively. This method is ecologically beneficial, and because it needs only a small amount of solvent (less than 10 ml) it is not expensive and may be used as a quick screening in several fields.
使用一种改良的玻璃设备对水、土壤和食品样品进行处理，以实现同时进行蒸汽蒸馏/溶剂萃取。添加了22种农药（其中大多数含有卤素）和多氯联苯的加标样品，水样在1.5小时后、土壤和植物性食品样品在5小时后分别获得了良好或非常好的回收率。该方法具有生态效益，并且由于仅需少量溶剂（少于10毫升），成本不高，可用于多个领域的快速筛查。
