Relationship between Pb/Cd adsorption and metal oxides on surface coatings at different depths in Lake Jingyuetan

Adsorption of heavy metals to metal oxides on surface coatings of sediments in aquatic environments is one of the most important factors governing their toxicity. Many previous studies were carried out to examine relationships between characteristics of surface coatings and heavy metal adsorption. However, a number of uncertainties existed in the related mechanisms. Especially, the effect of depth, at which surface coatings are developed, was …
