摘 要：欧盟《关于化学品注册，评估，授权与限制》（简称REACH法规）是欧盟对进入其市场的所有化学品进行预防性管理的一部法规。“高关注物质”简称SVHC，是法规中的一个特有名词，频繁出现在检测，授权，限制等内容中。 邻苯二甲酸酯(PAEs)广泛以增塑剂等形式存在于化学行业，与人类的生活栖息相关。同时，PAEs也被视为环境常见的污染物之一，是世界卫生组织(WHO)1995年公布的必须控制的一类扰乱内分泌的化学物质。因其随着时间的推移可从基质中释放迁移出来，且在环境中稳定持久，具有生物累积和放大效应，最终通过食物链而危及人类健康。本文用气相色谱-质谱联用技术(GC-MS)对已被列入15项高关注物质清单的邻苯二甲酸酯类（邻苯二甲酸二丁基酯(DBP)，邻苯二甲酸二（2-乙基己基）酯(DEHP)，邻苯二甲酸甲苯基丁酯(BBP)在塑料及其相关产品进行分析研究。

Abstract: The EU REACH regulation is the EU's access to their markets for all chemicals of a preventive management regulation. "Substances of Very High Concern" referred to SVHC, is one of specific term to the the regulations, which frequently appears in the detection, authorization, and restrictions. Phthalic acid esters (PAEs) as a kind of plasticizer are widely used in the chemical industry, and have a deep relation with human's life. At the same time, the PAEs are also considerated as a common pollutant to the environment. The World Health Organization (WHO) announced that it was necessary to control the use of this kind of endocrine disrupting chemicals in 1995. As the time passby, it can release from the matrix, migration out, last stability in the environment, causing bio-accumulation and amplification. Ultimately, endanger human health through the food chain. In this paper, the technology used in detection of benzyl butyl phthalate (DBP), bis(2-ethylhexyl) phthalate(DEHP), dibutyl phthalate(BBP)) in the list of SVHC is the gas chromatography - mass spectrometry (GC-MS).
