“…A risk quotient (RQ) index was estimated to describe the possible hazard of Hg contaminants in the ecosystem, where the Hg concentration value was divided by the predicted no-effect concentration (PNEC) of Hg (0.04 mg kg -1 ) (F.5) (X. Li et al, 2019;Shao et al, 2020;Su et al, 2021).…”

Mercury is a hazardous contaminant, and it is necessary to clean up Hg contamination on an ongoing basis. However, Hg contamination and ecological risks have not become a particular concern in the community. As a first step, this study evaluated the environmental risk assessment of Hg contamination/pollution in ex-gold mining soil. The results showed that the average total Hg in ex-gold mining soil was 4.11 and 4.25 mg kg-1 for depths 0-20 and 20-40 cm, respectively, greater than the threshold limit set nationally (0.3 mg kg-1) and internationally (0.05-1 mg kg-1). The index of contamination/pollution factor and geo-accumulation of Hg were 13.70 and 1.39 at a depth of 0-20 cm, and 14.16 and 1.47 at a depth of 20-40 cm. The prospective ecological risk index and risk quotient were 5.48E2 and 1.03E2 at a depth of 0-20 cm, and 5.66E2 and 1.06E2 at a depth of 20-40 cm. The contamination/ pollution factor and ecological risk index indicate high Hg contamination and pollution in the soil. Therefore, appropriate technology is needed for the remediation process of ex-gold mining soil that considers all elements to a user-friendly level, such as amelioration technology with heavy metal inactivation techniques.

“…It is situated in a region with a subtropical monsoon climate (Kang et al, 2015). In addition to its uses for irrigation, shipping, and aquaculture, Taihu Lake serves as a major source of drinking water for the surrounding cities (Su et al, 2021). Situated in the southern region of Jiangsu Province, Taihu Lake forms a critical part of the Yangtze River Delta.…”

The development of the industrial economy in Taihu Lake has led to increased levels of bisphenol compounds (BPs), which are di cult to degrade and highly toxic, making them a research focus. This study aimed to determine the occurrence, sources, and ecological risks of bisphenol Z (BPZ), bisphenol C (BPC), bisphenol F (BPF), and bisphenol S (BPS). Surface water and sediment samples were collected and analyzed, revealing average BPs concentrations of 1227 ng/L and 11 ng/g (dry weight), respectively. BPS had the highest detection rate among the four BPs, followed by BPF. Pollutant levels were found to increase upstream and decrease downstream. In wild sh, the pollutants were found to be concentrated in the muscle, gill, liver, kidney, and brain tissues, indicating short-term exposure. Correlation and stable isotope analyses showed that BPF and BPS had similar origins, and sediments were found to be the primary source of the pollutants. Ecological and human health risk assessments showed low-risk levels, but the risks are still increasing and require attention. This study provides valuable information for the management and control of BP pollution in Taihu Lake.
