Tetrachloroisophthalonitrile (chlorothalonil) was applied under controlled conditions in 1985 to a cranberry bog for fungus control and for residue studies. Randomly selected samples of cranberries were analyzed for residues of chlorothalonil, its metabolite 4-hydroxy-2,5,6-trichloroisophthalonitrile, hexachlorobenzene, and pentachlorobenzonitrile by extraction, methylation, Florisil column cleanup, and electron capture gas chromatography. Because of interferences in the GC determinative step, previously reported methodology was modified. The total residues found in the test samples were well below the permissible limit for the parent and related compounds.
1985年，在可控条件下，将四氯间苯二甲腈（百菌清）施用于一片蔓越莓沼泽地，用于控制真菌及进行残留研究。通过萃取、甲基化、弗罗里硅土柱净化及电子捕获气相色谱法，对随机选取的蔓越莓样本进行分析，以测定其中百菌清、其代谢物4-羟基-2,5,6-三氯间苯二甲腈、六氯苯和五氯苯甲腈的残留量。由于气相色谱测定步骤中存在干扰，因此对先前报道的方法进行了修改。测试样本中发现的总残留量远低于母体及相关化合物的许可限量。
