Project name: The responses of constructed wetlands' performance to the accumulation of engineering nanomaterials

Description: Engineered nanomaterials (ENMs) with excellent physical and chemical properties were processed into all aspects goods. With utilization increasing, the massive ENMs are sinking into the sewer continually and drained into wastewater treatment systems. It has been reported that the types of ENMs including metal (or metal oxide), inorganic carbon and plastics nanomaterials actually exist in wastewater with concentrations approximately varying from 10 ng·L-1 to 1 mg·L-1. Fortunately, CW can effectively intercept ENMs, which can be removed about 87-98% containing wastewater. However, accompanying the accumulation of ENMs, the CWs performance is gradually deteriorating due to the change of microbiota composition to the accumulation of engineering nanomaterials. Hence, we explored those knowledge gaps in CWs exposing to three types of typical engineered nanomaterials (metal nanoparticles, carbon nanomaterials and nanoplastics) using high-throughput sequencing techniques. The sequences in this project database are the results of microbial 16S sequencing that reflect the responses of microbial community structure to ENMs accumulation for the prolonged time.
