Abstract:
Chlorinated paraffins (CPs) are widely used as flame retardants and plasticizers, which facilitate the release of CPs into various environmental media, such as water, sediment, dust, air, and soil. This study collects and deeply discusses the published CPs related studies. Through the analysis of release factors, we estimated the emission of CPs to the environment through generation and use, then found that CPs mainly exists in soil in different environment medias. Human activities, economic activities and economic level have an important impact on the occurrence of CPs in different regions. The analysis of population exposure shows that occupational exposure is significantly higher than others, but overall, the assessment of ecological risk and human exposure risk shows that CPs has limited harm to our ecological environment and human health. Furthermore, this paper introduces the control measures of SCCPs and MCCPs at home and abroad, which will provide supports for the risk assessment and control management of CPs in China and provide references for possible CPs elimination in the future. Based on the consideration of chemical management and risk assessment, it is urgent to further carry out the migration, transformation, and risk research of MCCPs and LCCPs in the future, especially to assess the potential economic, social, and environmental impact caused by CPs control, so as to better provide important scientific data and technical support for the control of CPs products and national implementation of the contract.
