RESEARCH ON POLLUTION AND REMEDIATION OF HEAVY METAL CONTAMINATED SEDIMENTS IN SUZHOU RIVER
ABSTRACT
Water sediment (sediment) is an important part of the rivers lakes and other natural water ecosystems and it’s also a significant integral link of material cycle in water ecosystem. Different states of heavy metal from environment enter into water settle down in sediment by adsorption biological uptake sedimentation and other ways and finally accumulated and gathered. This give rise to the concentration of heavy metals in
