摘要
硅氧烷是一类人工合成的化合物,具有高表面活性、耐高低温、抗辐射、耐腐蚀、电气绝缘以及生理惰性等特性.由于各种硅氧烷的大量生产和使用,此类化合物会释放并进入多种环境介质乃至生物体中,又因其难以被生物降解,进入环境介质后会造成潜在的生态风险.目前,已有大量文献报道了硅氧烷的来源及其在环境中的降解情况.基于此,笔者概述了几种典型的硅氧烷的来源,综述其在全球范围内多种环境介质中的分布水平以及环境行为,为进一步评估硅氧烷的环境风险和健康风险提供参考.
Abstract
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.
