Abstract: The problem of lake sediment pollution has attracted wide attention. To establish the feasible sediment quality guidelines (SQGs) is an important precondition for scientific evaluation and effective governance of polluted sediments. This paper describes the concept, developing trend and how to establish the methods of SQGs, and points out the key scientific problems and the prospects of SQGs. It is necessary to establish a sediment toxicity test standards system as soon as possible, to combine the Numerical Sediment Quality Guidelines closely with the Type of Biological Response to Sediment Quality Guidelines, to enhance research on the speciation, migration and transformation of the pollutants in sediments, to explore the SQGs under combined pollution conditions, and establishthe theoretical, technological and methodological systems of SQGs adaptable to the regional characteristics in China.

Key words: lake; sediment quality guideline; combined pollution; speciation
