二溴氯丙烷(1.2-dibrom-3-chloropane,简称DBCP)为淡黄色液体,沸点193℃,比重2.08,蒸气压0.8mmHg(20℃)的化合物。原体为90%DBCP与10%甲苯混合物。将其制成粉剂或乳剂(20%)的剂型,作为杀线虫农药而广泛被使用。1977年7月美国的DBCP乳剂制造厂的男性操作工人发现不妊症者,同年8月美国停止生产、出售,日本亦随即决定停止生产。1978年4月规定空气中DBCP的允许浓度
1.2-dibromochloropropane (DBCP) is a pale yellow liquid with a boiling point of 193 ° C, a specific gravity of 2.08 and a vapor pressure of 0.8 mmHg (20 ° C). The original is a mixture of 90% DBCP and 10% toluene. It is widely used as a nematicidal pesticide in the form of powder or emulsion (20%). In July 1977, male operatives at the DBCP Emulsion Factory in the United States found that those who were not pregnant were pregnant. In August of the same year, the United States stopped production and sales and Japan immediately decided to discontinue production. April 1978 Specifies the allowable concentration of DBCP in the air
