化学融雪剂对生态环境的影响

Effects of deicing chemicals on ecological environment

化学融雪剂用于清除道路积雪具有操作简便、价格低廉及融雪效果良好等优点,在国内外的寒冷地区应用广泛。随着化学融雪剂施用量的逐年增加,其对生态环境危害已日益凸现。本文结合近年来中国和其他国家有关化学融雪剂对生态环境影响的研究进展,阐述了化学融雪剂对土壤环境、地表水、地下水、植物和动物等的影响,并提出了今后该领域的研究建议,以期为化学融雪剂对城市环境污染和生态影响的防治技术研究提供科学依据。

Deicing chemicals are widely used to clear the pavement snow in the cold areas of China and many other countries, because of their simple operation, low price, and excellent snowmelting effect. With the increasing application of deicing chemicals, their negative effects on ecosystem and environment have appeared increasingly. Based on the related researches in China and other countries, this paper summarized the impacts of deicing chemicals on soil, surface water, ground water, plants and animals, etc. , and put forward some suggestions for the further research in this field to provide a scientific basis for the pollution prevention of deicing chemicals on urban environment and related ecosystems.
