Tris(2-chloroisopropyl) phosphate (TCIPP), a widely present organophosphate flame retardant, poses potential ecological risks due to its persistence and bioactivity in environmental media. However, in China, soil safety thresholds for TCIPP have not yet been established, primarily due to limited toxicity data. In this study, standard toxicity tests were conducted on five terrestrial plants (Brassica pekinensis, Brassica rapa var. chinensis, Triticum aestivum, Cucumis sativus, and Solanum lycopersicum) and one invertebrate species (Eisenia fetida), to evaluate the phytotoxic and ecotoxic effects of TCIPP. By combining our results with literature data, the predicted no-effect concentration (PNEC) of TCIPP in soil was derived, and an ecological risk assessment was conducted for TCIPP in Chinese soils. Results showed that B. pekinensis, B. rapa var. chinensis, and S. lycopersicum exhibited the highest sensitivity (root elongation and/or germination rate) to TCIPP with a no-observed-effect concentration (NOEC) of 80mg/kg, while wheat T. aestivum (germination rate) showed the least sensitivity with a NOEC of 320mg/kg. The growth NOEC for E. fetida was determined to be 1mg/kg. Using the species sensitivity distribution (SSD) method, the calculated PNEC value of TCIPP in soil was 0.035mg/kg. Environmental monitoring data revealed that TCIPP concentrations in soils across different regions of China ranged from 0.01 to 444ng/g. Risk quotient (RQ) analysis indicated that TCIPP poses a high ecological risk in industrial areas (maximum RQ = 12.57), whereas agricultural soil showed relatively low risk.
