The stress response mechanisms of activated sludge to exposure of CdSe quantum dots
In order to reveal the biotoxicity of CdSe quantum dots (QDs) in complex environmental systems, the activated sludge was selected, and the exposure effects of CdSe QDs (0.1-10 mg-L-1) on the operation efficiency, sludge performance and microbial metabolism in sequencing batch reactor (SBR) were discussed.
