苯乙烯是合成橡胶和塑料的重要单体之一,也是一种普遍存在的环境空气污染物。它是具有芳香气味的无色液体,易挥发,具有中等偏低毒性[1]。苯乙烯主要通过呼吸道吸收,少量可经皮肤和胃肠道吸收。苯乙烯的急性毒性作用主要是对中枢神经系统的抑制和对皮肤粘膜的刺激。长期接触低浓 Styrene is one of the important monomers in synthetic rubbers and plastics and is also a ubiquitous ambient air pollutant. It is a colorless, aroma-like liquid that is volatile and has moderate to low toxicity [1]. Styrene absorbed mainly through the respiratory tract, a small amount can be absorbed through the skin and the gastrointestinal tract. The acute toxicity of styrene is mainly the inhibition of the central nervous system and skin and mucous membrane stimulation. Long-term exposure to low concentration
