中文百科

污染物

污染物是指直接或间接损害环境或人类健康的物质,污染物有自然界产生的,如火山爆发、森林大火产生的烟尘;也有人类活动产生的,环境科学主要研究和关注人类活动产生的污染物。

污染物是在特定的环境中,达到一定的浓度或数量,持续一定的时间的某些环境不需要的物质。并不一定是有毒物质。例如氮和磷本来是植物必须的营养元素,但当在水体中达到一定的浓度,持续一定的时间而不能被稀释,就会成为水体富营养化的主要元凶,使有害藻类迅速繁殖,鱼类等水声动物会因为缺氧而窒息死亡。

如重金属本来在自然界中也存在一定丰度,但如果因为人类活动,是某一地点的重金属浓度极大地增加,就会使当地的人类、动物和植物中毒。有的重金属如汞本来不会被动植物吸收,但排放到自然界后,在一定的条件下会被微生物转化成可溶性的甲基汞,会被鱼虾吸收,并通过食物链在吃鱼的动物和人类体内积累,造成神经性疾病。

A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in the long term. However the degradation products of some pollutants are themselves polluting such as the products DDE and DDD produced from degradation of DDT.
