中国是全球水污染最严重的国家之一，全国多达70%的河流、湖泊和水库均受到影响。一项全国性调查表明，在2007年排入各种水体的有机污染物（以化学需氧量表示）中，近20%源自工业。这些工厂致使重要水资源遭受污染，研究表明，中国约20%-30%的水污染是由于制造出口商品而造成的。《GB8978-1996 污水综合排放标准》中规定了69种水污染物的允许排放浓度，主要为传统的、大家已熟知的废水污染物。 [1]  然而，随着中国成为全世界发展最快的大型经济体，各类工业排放的众多化学品也随之增加，一些有毒有害的有机污染物尤其令人担忧。这些有毒有害物质一旦排放到环境中，就会对人类健康和生态系统构成长期威胁。许多国家甚至全世界都禁止或限制这些有毒有害物质，但是在我国尚未全部列为禁止或严格限制物质，也未列入相关行业废水排放标准监测污染物名单中，且污水处理厂的处理工艺也还未针对这些物质进行相关设计。企业可以委托环境保护部门或第三方检测机构如SGS进行废水限用物质检测，获取各类限用物质的检测数据，了解生产过程中的各类用水特征，为消除有毒有害化学品排放、减少工业水污染危害而努力。

China is one of the most polluted countries in the world. Up to 70% of the rivers, lakes and reservoirs in China are affected. A national survey shows that nearly 20% of the organic pollutants discharged into various water bodies (expressed in chemical oxygen demand) in 2007 originated from industry. These factories have polluted important water resources. Studies show that about 20-30% of China's water pollution is caused by the manufacture of imported goods. The GB8978-1996 Comprehensive Wastewater Discharge Standard stipulates the allowable discharge concentration of 69 kinds of water pollutants, mainly traditional and well-known wastewater pollutants. [1] However, with China becoming the world's fastest-growing large economy, a large number of chemicals emitted by various industries have also increased, and some toxic and harmful organic pollutants are particularly worrying. Once released into the environment, these toxic and harmful substances will pose a long-term threat to human health and ecosystems. Many countries and even the whole world prohibit or restrict these toxic and harmful substances, but in our country, they are not all listed as prohibited or strictly rzhongyaodou.71ix.comkakou.37ix.com.cnzhongyaocai.71ix.combaohuqi.07858.netzaoxingzd.37ix.c

Enterprises can entrust environmental protection departments or third-party testing institutions such as SGS to detect wastewater restricted substances, obtain the testing data of various restricted substances, understand the characteristics of water use in the production process, and strive to eliminate toxic and harmful chemicals emissions and reduce industrial water pollution hazards.
