美国职业安全卫生研究所(NIOSH)最近的报告指出:肺和结肠癌发病率的增加与丙烯腈的接触有关。 1977年5月杜邦公司认为NIOSH经初步的流行病学调查结果证实在卡姆登和南卡罗林那州的杜邦纤维工厂中接触丙烯腈的工人的癌发病率较高。同年4月NIOSH收到制造化学师协会(MCA)用大鼠进行丙烯腈摄入或吸入的实验,非正式的报告认为本毒物可形成多种肿瘤,包括癌。一、概况丙烯腈为一易爆易燃物质,沸点77℃,蒸气压80毫米汞柱(20℃)。丙烯腈的毒作用类似氰化
A recent report by the National Institute for Occupational Safety and Health (NIOSH) states that an increased incidence of lung and colon cancer is linked to exposure to acrylonitrile. In May 1977, DuPont considered NIOSH’s preliminary epidemiological findings to confirm the higher incidence of cancer among workers exposed to acrylonitrile in the Dupont fiber plant in Camden and South Carolina. In April of the same year, NIOSH received an experiment with rats of the Society of Manufacturing Chemists (MCA) for acrylonitrile uptake or inhalation. Unofficial reports suggest that the toxicant can form a wide range of tumors, including cancer. First, an overview of acrylonitrile as an explosive material, boiling point 77 ℃, vapor pressure 80 mm Hg (20 ℃). Acrylonitrile toxicity similar to cyanide
