“…The third main component mainly associates with industrial activities, electronics, machinery manufacturing and domestic sewage discharge. There are five outfalls distributed near S11 downstream of the Xinfengjiang Reservoir Dam; meanwhile, the downstream of the reservoir converges into the Dongjiang River, in close proximity to industrial parks such as the Linjiang Industrial Zone and Zijin Industrial Park, which mainly produce electronics and electrical machinery [ 27 ]. The main pollutants are Cr, As, Cu and Pb.…”

“…Jinfeng Chen et al [ 23 ] determined the content of trace elements in the riverbed, bankside and adjacent agricultural soil of the Zhongxing River which is located in the Dongjiang River Basin. Yun-jiang Yu et al [ 27 ] evaluated the heavy metals and pollution levels in the sediments of the Xinfengjiang Reservoir and the Dongjiang River Basin. Few researchers have addressed the problem of response of fish species to heavy metal pollution in the Xinfengjiang River.…”

Xinfengjiang River, the largest tributary of Dongjiang River, plays a key role in the water supply of Heyuan, Huizhou, Guangzhou and even the Pearl River urban agglomeration. It is crucial to determine the pollution status, potential ecological risk degree of heavy metals in Xinfengjiang river sediment and their influence on the abundance of fish species. In this paper, seven heavy metal concentrations in sediment from the Heyuan section of the Xinfengjiang river were investigated. The order of average concentration was: As > Zn > Pb > Cr > Cu > Cd > Hg. The average concentrations of Cd, Zn and Cu in the upper reaches of the Xinfengjiang Reservoir were significantly higher than those in the reservoir. The mean value order of Igeo was: Cd > Zn > Pb > As > Cu > Cr > Hg. Cd and As had the highest ecological risk index and the greatest threat to the ecological environment. Pearson correlation analysis and principal component analysis demonstrated that the pollution source of heavy metals such as Cu and Cd are much more likely to originate from the mine fields located in the northeast of the sampling sites. In addition, agriculture, electronic industry and domestic sewage also contributed to the concentration of heavy metals in different degrees. Redundancy analysis showed that the abundance of Cypriniformes was negatively correlated with Cu and Cd concentrations, suggesting that mining activities might indirectly affect the abundance of fish species.

Dissolved organic matter (DOM) and Cu(II), originated from livestock manure, often co-exist in livestock effluents. The effects of DOM on adsorption of Cu(II) by adsorbent remain unknown, which may prevent the removal of Cu(II) from livestock effluents using the method of adsorption. In this study, the effects of DOM on adsorption behaviors of Cu(II) by Aliinostoc sp. YYLX235, a epiphytic cyanobacterium, were investigated. The results showed that Aliinostoc could effectively bind with Cu(II) and remove it from water. Rather than absorption, most of Cu(II) were bound on the cell surface through adsorption. The decay of Aliinostoc did not resulted in rapid release of Cu(II) into water. The amount of Cu(II) adsorbed by Aliinostoc through ion exchange and complexation was decreased by DOM addition.
