In terms of water environment, if 2-iodine-1,1,1-trifluoroethane enters the water body, it is difficult to dissolve in water due to its hydrophobicity, but it is easily adsorbed on suspended particles or sediment. This substance can be transmitted and enriched through the food chain. After ingestion by aquatic organisms, it will accumulate in the body, affecting its physiological functions, such as disrupting the endocrine system and damaging the nervous system. And because of its stability, it can remain in the water ecosystem for a long time, continuously affecting the water ecological balance.
In the soil environment, it will adsorb on the surface of soil particles, change soil physicochemical properties, and affect soil microbial activities and soil fertility.
