汽车用材料中多环芳烃限值与检测标准分析

多环芳烃是一类持久性有机污染物的总称,这类物质由于具有较高的脂溶性、强烈的致癌性以及难以自然降解的性质而被广泛关注。汽车产品的多环芳烃主要存在于非金属材料中。在汽车成为大众消费品的同时,人们越来越注重汽车使用中的环保与健康安全的问题。本文系统地对国内外汽车材料中多环芳烃限值要求及检测方法等相关标准进行梳理分析,形成对汽车行业禁限用物质多环芳烃的管控建议。

Analysis of Limit Requirements and Test Methods for Polycyclic Aromatic Hydrocarbons in Vehicles’ Materials

Polycyclic aromatic hydrocarbons(PAHs) is a general term for a class of persistent organic pollutants. These substances are widely concerned because of their high fat solubility, strong carcinogenicity, and difficult to degrade naturally. PAHs exist in vehicles nonmetallic materials in the form of tires and interior parts. As the vehicles becomes the mass consumer goods, people pay more and more attention to the environmental protection and health and safety problems in the use of them. This article will systematically study the domestic and foreign relevant standards such as the limit requirements for PAHs in vehicles’ materials and their detection methods to form recommendations for the control of PAHs in the automotive industry.
