Abstract The ecological risks and health hazards of heavy metals pollution in Taihu Lake have received widespread concern. This study has developed a nationwide dataset on pollutant loads in species, and the dataset records 55,297 data from 310 articles, covering 778 species and 537 pollutants. In this paper, we extract and systematically integrate data on heavy metals concentrations in Taihu fish from the dataset. The Pi (single pollution index) and MPI (metal pollution index) models were used to assess the level of contamination in fish and the THQ (target hazard quotient) and ILCR (incremental lifetime cancer risk) models were used to assess the health hazards of fish consumption. The contamination levels varied in a feeding habit and living habit dependent manner. The risk of non-cancer health is the highest in omnivorous fish, then in carnivorous fish and herbivorous fish. ILCR model predicted that the values of As and Cd in omnivorous fish for children exceeded the risk threshold limits set by the EPA, and the ILCR values of As in omnivorous fish and Cd in carnivorous fish for adults also exceeded the risk threshold limits. In all, this study provided a comprehensive understanding of the risk of heavy metals in Taihu.

Heavy Metals Pollution

Drinking water of safe quality is a critical issue for human survival and health. Water pollution by heavy metals is very crucial because of their toxicity. This study assesses potential of heavy metals pollution in drinking water in Garmian Region, East Iraq. Water samples were investigated for 23 heavy metals and 6 chemical contaminants collected from 16 locations. The analysis was performed by using coupled plasma optical emission spectroscopy (ICPOES, Spectro Arcos). High levels of Al, Se, Sr, and Fe have been detected at certain locations in study area. Statistical analysis techniques of the correlation matrix (CM), and cluster hierarchical analysis (CA) were conducted. The heavy metals pollution index (HPI), heavy metals evaluation index (HEI), and contamination Index (Cd) were used applied. These indices linked with the statistical analysis to interpret relationships among the tested parameters in water samples and to investigate the pollution sources over the study region. Even with the significant correlations between the HPI, Cd, and HEI, they showed dissimilar impact of examined heavy metals on the water quality. The most reliable pollution evaluation index of HEI for drinking water showed that 44% of the water samples is critically polluted. Sources of the contamination are most likely coming from natural geological sources. Anthropogenic impact was only noticed at several sites in the study area.

Heavy Metals Pollution

Heavy metals (Hg, As, Pb, Cd, Cr, Cu) pollution in soil samples of Rosa sterilis planting areas located in Wudang District in Guiyang and Pingba County in Anshun was studied using a new evaluation theory of pollution loss rate, and following a series of methods for Rosa sterilis leaf including over standard rate, enrichment coefficient, single pollution index and comprehensive pollution index, the heavy metals pollution of the two Rosa sterilis planting areas was analyzed and evaluated. The results showed that the soil comprehensive pollution loss rate ranged from 12.73% to 28.26% in Wudang District samples, most of which belong to light pollution level. The comprehensive soil pollution loss rate of the sampling points in Pingba County varied from 9.68% to 16.10%, which belong to fairly clean level. Meanwhile, the experimental results for the Rosa sterilis leaf showed that the contents of Cr and Pb in both planting areas exceeded the permissible limit, while other elements were below the safe limit. The six heavy metal elements in Rosa sterilis leaf did not accumulate.
