Sources and Distribution of Organic Pollution in Some Nature Reserves of China
In nature reserves of China,organic pollutants have been distributed in environmental media such as atmosphere,water(including sediment)and soil,and eventually accumulated along the food web.However,researches are currently scattered.Through the collation and induction of 29 related literature,it can be found that the atmospheric transport is the most common input route in terms of pollution sources,while human activities near nature reserves lead to high-concentration pollution from point sources or small-scale non-point sources.In terms of pollution distribution,concentra-tions of pollutants in atmosphere,water and soil are less affected by the distance from the pollution source than those in sediments and organisms.Therefore,although the pollution in some nature re-serves has been effectively controlled,the distribution and transfer of emerging organic pollutants in different kinds of media is still insufficient.In addition,the small quantity of relevant studies indicates that this area still needs an increasing attention.
