苯乙烯系无色至淡黄色液体,由乙基苯脱氢而成,工业上主要用于合成塑料、树脂及橡胶的单体。1985年,美国将其列为10种产量最多的化学品之一,达3.8万吨以上。苯乙烯毒性在40年代已作过较详细的研究,1987年,美国政府工业卫生学家协会推荐本品阈限值(TWA)为215mg/m~3,短时间接触阈限值为425mg/m~3。有关苯乙烯的致突变、致畸作用已有不少报道,国外还对其致癌作用进行了研究,现将近年有关此方面材料作一扼要综述。 Styrene is a colorless to light yellow liquid made from ethylbenzene dehydrogenation, mainly used for the synthesis of monomers for plastics, resins and rubbers in the industry. In 1985, the United States listed it as one of the 10 most-produced chemicals at more than 38,000 tons. Styrene toxicity has been studied in more detail in the 1940s. In 1987, the American Government Association of Industrial Hygienists recommended a TWA of 215 mg / m 3 and a short-term exposure threshold of 425 mg / m ~ 3. There have been many reports about the mutagenic and teratogenic effects of styrene, and the carcinogenic effects of it have also been studied abroad. In recent years, a brief review on the materials in this regard has been made.
