Research Progress on the Distribution of Siloxanes in Environmental Media
Siloxane is a synthetic compound with many excellent properties such as high surface activity,high and low temperature resistance,radiation resistance,corrosion resistance,electrical insulation and physiological inertia.Due to the mass production and use of various siloxanes,such compounds are released into a variety of environmental media and even organisms.Because it is difficult to be biodegraded,it can persist after entering into the environmental medium,thus causing potential ecological risks.At present,the environmental sources of siloxane release and its degradation in the environment have been reported in many literatures.Based on this,this paper summarizes the sources of several typical siloxanes,reviews their distribution levels and environmental behaviors in various environmental media worldwide,and also provides a reference for further assessing the environmental and health risks of siloxanes.
