本文介绍了二苯醚除草剂、CNP、NIP 和 X-52 中多氯二苯并二恶英、二苯并呋喃和相关化合物的分析。 CNP 制剂中四 CDD、五 CDD 和四 CDF 的含量分别约为 150、30 和 15 ppm。 NIP 和 X-52 含有较低氯的类似物。 CNP 中 PCDD 的异构体分布与氯酚反应的估计结果一致。在施用季节受到 CNP 严重污染的淡水鱼样品中还含有 0.2 ppb 的 1,3,6,8-tetra-CDD。
This paper describes the analyses of polychlorinated dibenzodioxins, dibenzofurans, and related compounds in diphenyl ether herbicides, CNP, NIP, and X-52. The levels of tetra-, penta-CDDs, and tetra-CDFs were about 150, 30, and 15 ppm, respectively in CNP formulations. NIP and X-52 contained lower chlorine alalogs. Isomer distribution of PCDDs in CNP agreed with an estimate from the reaction of chlorophenols. Freshwater fish samples heavily contaminated with CNP in the application season also contained 0.2 ppb of 1,3,6,8-tetra-CDD.
