Abstract:
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.
