Short chain chlorinated paraffins (SCCPs) are persistent organic pollutants (POPs) which are widely used in the industrial production of cables, artificial leather, etc. SCCPs are biotoxins and can enter the soil environment through various pathways, threatening the ecological and environmental safety of soil. As a newly identified pollutant under UNECE, a SCCOs safety benchmark under the freshwater environment has been made, however, relevant research and benchmark under the soil environment are still lacking. To address this gap, this study analyzes published data on SCCP toxicity in soil and aquatic organisms to derive the predicted no effect concentration in soil (PNEC_soil) using the species sensitivity distribution (SSD) or partition coefficient (PE) methods. Briefly, soil toxicity data using SSD method yielded a PNEC_soil value of 71.46 mg/kg, and aquatic toxicity data using PE method yielded a PNEC_soil value of 10.1 mg/kg. By comparing with related studies, the PNEC_soil value obtained by PE method was selected as the ecological safety benchmark value for SCCPs in soil. The benchmark value obtained from this study is somewhat different from those of other countries due to the differences in research conditions such as species selection and research methods. The environmental risk of SCCPs in soil was also evaluated by risk quotient method, which showed that the current HQ values of SCCPs in soil ranged between 7.23×10^-5 to 0.5017 for different soil types in the main regions of China, which is considered low risk. The results of this study provide a reference for the development of environmental quality standards and risk assessment of soil SCCPs.
