非生物降解过程在消除土壤中的许多农药方面起着重要的作用。

Nonbiological degradation processes play an important role in the dissipation of many pesticides in soil .

不仅如此，生物降解对污染物是永久的降解，而不像非生物降解，有时污染物会由一种形态转变为另一种形态，即二次污染。

Moreover , biodegradation is a permanent degradation of pollutants , rather than non-biodegration . Sometimes , non-biodegradation may keep the pollutants into another form , that is , secondary pollution .

重金属离子以各种形态存在于饮用水中，由于其非生物降解性及富集功能，微量浓度的重金属离子即可产生毒性效应以及持续性和放大作用，对人类身体健康构成极大威胁。

Heavy metal ions exist in drinking water in various forms . It is not biodegradable and even trace concentration has detrimental risk to human health . It also has the continuity , amplification and the function of enrichment .
