Chlorinated paraffins (CPs) are used as flame retardants, plasticizers, and metalworking fluids, which have varying contents of toxic short-chain chlorinated paraffins (SCCPs). Based on the study of several relevant production and consumption sectors, this paper classifies the consumption of CPs among sectors and provides an emission inventory and the provincial emission distribution of SCCPs in China in 2010-2014 based on the consumption patterns and emission factors of each sector. The total emissions of SCCPs in China in 2014 were 3083.88tons, with emissions to the atmosphere and water accounting for 894.81tons and 2189.07tons, respectively. The largest emission source was from metalworking fluids, with total emissions of 2459.12tons, of which 756.65tons went to the atmosphere and 1702.47tons to water. Our results show that SCCP emissions were mainly concentrated in the eastern, more developed regions and that Jiangsu Province was the biggest producer in China, with total emissions of 1853.06tons, of which 562.61tons were to the atmosphere and 1290.46tons to water.
氯化石蜡（CPs）被用作阻燃剂、增塑剂和金属加工液，其中含有不同含量的有毒短链氯化石蜡（SCCPs）。基于对几个相关生产和消费领域的研究，本文根据各领域的消费模式和排放因子，对 CP 在各领域的消费进行了分类，并提供了 SCCPs 在 2010-2014 年期间在中国的排放清单和省级排放分布。2014 年中国 SCCPs 的总排放量为 3083.88 吨，其中大气排放和水排放分别为 894.81 吨和 2189.07 吨。最大的排放源来自金属加工液，总排放量为 2459.12 吨，其中 756.65 吨排向大气，1702.47 吨排向水体。研究结果表明，SCCP 排放主要集中在东部发达地区，江苏省是中国最大的排放源，总排放量为 1853.06 吨，其中 562.61 吨排向大气，1290.46 吨排向水体。
