过氧化甲乙酮(MEKP)是世界上应用最为广泛的不饱和聚酯树脂固化剂,职业和非职业接触人数逐年增多,不断出现中毒的个案报道,目前我国尚未制定MEKP职业接触限值。该文就过氧化甲乙酮的毒性以及国外对其职业接触限值的研究情况作一简要综述,为制定过氧化甲乙酮的职业接触限值提供参考。 Methyl ethyl ketone peroxide (MEKP) is the most widely used unsaturated polyester resin curing agent in the world. The number of occupational and non-occupational exposure has been increasing year by year. MEKP has been reported in a number of cases. At present, China has not yet established the MEKP occupational exposure limit. In this paper, the toxicity of methyl ethyl ketone peroxide as well as the status quo of its exposure to occupational exposure in our country are briefly reviewed. It provides a reference for establishing the limit of occupational exposure to methyl ethyl ketone peroxide.
