Biodegradation is the major route
of removal of trichloroethane from the aquatic environment and from
industrial waste water finding its way into sewage treatment plants. The
material can be degraded by either the aerobic or anaerobic route but
the latter is of the greatest importance. There are a number of
potential ways that 1,1,1-trichloroethane can be utilised by anaerobic
bacteria but there is sufficient work to show that once bacterial
populations become acclimatised to this material it is rapidly removed
from contaminated waste water with a DT50 of approximately one day. The
bacteria present in sewage treatment plants appear reasonably tolerant
of the material with an LC50 of 360mg/L. In practice this concentration
should never be reached except following accidental spillages.
