松花江休养生息前后酚类污染物浓度变化对比

酚类化合物具有一定的毒性, 自然环境中不易分解, 是重要的环境污染物。松花江在休养生息前水体中酚类 化合物污染严重, 且呈现出多元酚的污染态势。通过对连续三年全江 7个重点断面酚类化合物浓度进行对比分析, 发现休养生息措施已经使得松花江下游江段水体中的多元酚类含量大幅度下降。 Phenolic compounds have some toxicity and are not easy to break down in the natural environment, so they are impor2 tant environmental pollutants. Pollution from the phenolic compounds is severe in the Songhua River before the recuperation and multiplication, and pollution trend shows the existence of polyphenols. Based on the comparative analysis of concentrations of phenolic compounds at seven key sections of the Songhua River in three consecutive years, the recuperation and multiplication measures can reduce the content of polyphenols significantly in the downstream of the Songhua River. 2011 年中国环境监测总站转型发展科研支撑项目/ 休养生息对松花江出境水质变化及界河黑龙江影响趋势的研究0 (2011ZX2SS004 201)
