Additional information

The distribution model predicts that concentrations in soil and sediments will be extremely low (<0.01% of total releases to the environment). Toxicity to aerobic and anaerobic bacteria has already been addressed in previous summaries and it is evident that under the correct conditions bacteria are capable of degrading 1,1,1-trichloroethane by a number of different routes. Studies on the effects on macroorganisms are limited to earthworm which is not sensitive to 1,1,1-trichloroethane. Similarly protozoa also appear to be relatively insensitive.

In view of the very low levels expected to reach this environmental compartment the opinion of experts in this area is that this compartment can be discounted for risk assessment purposes. The applicant supports this view.
