“…Human health risks of selected aquatic products decreased in the order of M. nipponense (1.998) > C. prawn (1.450) > R. giurinus (1.213) > H. prognathus Regan (0.355), and THQ of As was the major contributor to TTHQ. This study was consistent with previous reports in Dianchi Lake, in which As in aquatic products showed the most significant health risk (Qian et al, 2020). Except for the THQ of As in Chinese white prawn (1.119) and M. nipponense (1.187), the THQ of other metals to each aquatic consumption was generally less than 1, indicating that residents would not experience significant health risks from the intake of individual metal through selected organisms (Table S12).…”

“…According to previous literature, the high heavy metal background value in this study area might overestimate the adverse effect of metals when using the RI and hazard quotient (HQ) models (Qian et al, 2020). Therefore, the Igeo was selected to assess the risks of heavy metals in sediments, whose calculation formula was as follows:…”

“…Chinese white prawn, Macrobrachium nipponense, Hemisalanx prognathus Regan, and Rhinogobius giurinus are four of the major commercial aquatic products consumed frequently by local residents. Although several studies had investigated heavy metals in fish community, only few of them addressed the transportation of metals in aquatic environments to the high trophic level and result in potential health risks through the food chain (Yang et al, 2017;Qian et al, 2020).…”

Heavy metal contamination in lakes caused by the rapid industrialization and urbanization is a serious problem. In this study, 12 heavy metals were systematically surveyed in aquatic environment and organisms of Dianchi Lake. Results showed that heavy metals pollutions in surface water exhibited a decreasing order of Ba > Fe > Zn > Mn > As > Ni > Cr > Cu > Pb > Cd > Co, equipped a consistency in spatial distribution, seriously contaminating the northern and southern parts. The average concentration of sedimentary heavy metals appeared in an order of Fe > Mn > Zn > Ba > Cu > Pb > Cr > As > Ni > Co > Cd > Ag. The main existing fraction (51.9–75.0%) of Cu, Pb, Cr, As, Fe, Co, Ni, Ag, and Ba in sediments was residual fraction, whereas the exchangeable fraction (40.9–62.0%) was the dominant component for Cd, Zn, and Mn. Among the selected aquatic organisms, Cu, Pb, Zn, and Ag possessed a strong bioaccumulation effect, followed by Mn, Fe, Co, and Ni. Ecological risk assessment indicated that Cu, Cr, and Zn were the dominant heavy metal contaminants in surface water; Cd presented the disastrous risk and accounted for the considerable proportion of ecological risk in sediments. Human health risk evaluation showed that the selected aquatic products of Dianchi Lake were not absolutely safe, and As was the major contributor. This study systematically revealed heavy metal distributions in aquatic environments, which was conductive to environmental safety and human health.

“…Further, it has been well known that long-term exposure to toxic PTEs can result in adverse effects on the nervous, immune, and endocrine systems (Li et al 2014), and lead to cancer or disability in both children and adults (Wu et al 2018;Patlolla et al 2012). And other health problems such as stomach and heart diseases, hypertension, and anorexia (Qian et al 2020). Chronic PTEs toxicity has adverse effects on human health, such as lung disease, renal failure, bone fracture, and may lead to hypertension, fertility and hormonal, immune, liver function, and endocrine system deficiency (Yuanan et al 2020).…”

Accelerated mining activities have increased water contamination with potentially toxic elements (PTEs) and their associated human health risk in developing countries. The current study investigated the distribution of PTEs, their potential sources and health risk assessment in both ground and surface water sources in mining and non–mining areas of Khyber Pakhtunkhwa, Pakistan. Water samples (n=150) were taken from selected sites and were analyzed for six PTEs (Ni, Cr, Zn, Cu, Pb and Mn). Among PTEs, Cr showed high mean concentration (497) μg L–1, followed by Zn (414) μg L–1 in mining area, while Zn showed lowest mean value (4.44) μg L–1 in non-mining areas. Elevated concentrations of Ni, Cr and moderate level of Pb in ground and surface water of Mohmand District exceeded the permissible limits set by WHO (2017). Multivariate statistical analyses showed that pollution sources of PTEs were mainly from mafic-ultramafic rocks, acid mine drainage, open dumping of mine-wastes and mine tailings. The hazard quotient (HQ) was highest for children relatively to adults, but not higher than the US-EPA limits. The hazard index (HI) for ingestions of all selected PTEs were lower than the threshold value (HIing <1), except Mohmand District which showed (HI >1) in mining areas through ingestion. Moreover, the carcinogenic risk (CR) values exceeded the threshold limits for Ni and Cr set by the US-EPA (1.0E−04 to 1.0E−06). In order to protect the drinking water sources of the study areas from more contamination, the management techniques and policy for mining operations need to be implemented.

“…Mining, smelting, traffic, machinery manufacturing, sewage, chemical fertilizer and pesticide are the main contributors to environment pollution by heavy metal [ 2 , 3 , 4 , 5 ]. Once these heavy metals are discharged into water environment, they could threaten the ecosystem and public health due to the bioaccumulation or biomagnification in the aquatic food web [ 6 , 7 , 8 , 9 , 10 , 11 ]. Particularly, the risk level could be higher in areas with high background values such as Karst region of Guizhou Province in southwestern China [ 12 , 13 , 14 , 15 , 16 ].…”

In the Karst area of southwestern China, the heavy metals in the sediment of a reservoir are determined by both human activities and the high background values. Thus, this study explores the change of heavy metals in surface sediment after ten-year sustainable development in the upstream areas of a reservoir, Huaxi Reservoir, located in Guiyang of southwestern China, then evaluates the risk of these heavy metals to water environment systematically and finally identifies the sources in both 2019 and 2009. The results reveal that all of the measured heavy metals decrease dramatically and their spatial distributions change from the increase-decrease pattern to decrease-increase pattern, implying different locations of main source input. The risk indices based on the total or average content and relative or reference values have decreased to the lowest level. However, those indices calculated from the absolute content of each metalloid still show a low or a moderate risk because of the high background value, such as As and Cr. Moreover, although only one main source of heavy metals is identified in both 2019 and 2009, the risk from human activities still cannot be neglected because agricultural production and infrastructure construction would promote the weathering of soil and then these heavy metals from the soil will be brought into the reservoir with the rainfall-runoff process. The high background value of specific heavy metals, e.g., As and Cr would still exert some challenges to the water environment protections because the non-point source input of heavy metal cannot be controlled easily by promulgating a series of bans. These results provide important reference for creating the policies of water environment protection, especially in some Karst area of southwestern China that exhibits high background value of heavy metals.
