“…In sediments, the TE concentrations showed narrow variations relative to riparian soils, with CVs ranging from 12.14% to 44.55%, suggesting that environmental disturbance to sediments is relatively minor. Yuan et al 39 also monitored the pollution status of sediment quality in the Jinsha River. The sediment concentrations of Cu, Zn, V, As, and Cd in the Jinsha River were of the same order of magnitude as those in the LRJR.…”

Risk assessment and source apportionment of trace elements in multiple compartments in the lower reach of the Jinsha River, China

Studies on trace element (TE) pollution in abiotic matrices have typically focused on water, sediment, and soil, either separately or in pairs. The importance of multi-media connectivity has been ignored. This study analyzed the concentrations of 6 TEs in three connected environmental compartments of a 28-km section of the lower reach of the Jinsha River. The ecological risk posed by TEs was higher in soil than in sediment. The contribution of exposure pathways to human health risk were ranked as ingestion > dermal contact > inhalation. An improved regional environmental risk index (RERI) method was then developed to evaluate the comprehensive risk on both ecology and human health caused by TEs. The average RERI value was generally higher in the wet season (0.42) than in the dry (0.41) and dry-to-wet transition seasons (0.08) because of the combined effects of the high TE concentrations in riparian soil and the long exposure time. Source apportionment indicated that industrial activities, weathering of parent rock, and agricultural activities were possible sources of TEs in this region. The methods and results of this study could inform local environmental management and provide references for similar cases wherein multiple compartments of river systems should be considered.

“…Sources of SCCPs and MCCPs were different in water and sediment; and both types of CPs had low to moderate ecological risk for sediment dwelling organisms. Yuan et al (2019) comprehensively studied the allocation, genesis, and ecological risks, for example, potential ecological risk index (PERI), modified risk assessment code (mRAC), modified hazard quotient (mHQ), and ecological contamination index (ECI) of metal and metalloid contaminations in aquatic sediment in Jinsha River, China, after testing about 50 sediment samples when Hg, As, Cu, Zn, Ni, Cr, Cd, Pb, Fe, and Al concentrations in sediment were 0.004-0.15, 2. 22-30.53, 10.30-247.61, 48.67-463.96, 0.05-0.73, 4.08-44.04, 2.53-155.2, and 18.7-98.5 mg/kg, respectively.…”

Geochemical characteristics and anthropogenic sources of metals were different, and besides, spatial fluctuation in metal concentrations due to different river courses and diverse land‐use patterns such as arable land, wood land, grass land, residential and industrial land and unused land was noticed for Ni, Cu, Cd, Cr, and Hg in the ecosystem.…”

Aquatic sediments are contaminated by different anthropogenic activities and natural deposition. This review manuscript has discussed on published manuscript in 2019 based on monitoring and identification of contaminants, GIS application and isotopic evaluation for monitoring of pollutants, physicochemical and biochemical fate and transport of the pollutants as well as remediation and toxicity analysis so that environmental and ecological impacts due to pollution can be minimized.

“…One of the side effects of urbanization and industrialization is the contamination of the environment. Although toxic elements are mostly anthropogenic in origin, those originating from lithogenic processes (natural processes) also contribute to environmental contamination (Gibbs 1973;Jain 2004;Yi and Zhang 2012;Yuan et al 2019). Sediments washed down from the catchment areas of rivers are the chief contributors of heavy metal pollutants to the oceans.…”

Increasing toxic metal content in aquatic products has become a universal burden due to the risk to aquatic organisms and human health risks associated with consumption of these products. In this study, toxic metal distribution and accumulation in the organs of fish and bivalve species of economic and culinary importance from the lower reaches of the Yangtze River are examined, and the corresponding health risks are also investigated. In general, the viscera and gill show higher concentration of metals than other tissues. The order of the accumulation sequence of metals in muscle tissue of fish and bivalve is: Zn > Cu > Mn > Cr > As > Hg > Pb > Cd and Mn > Zn > Cu > As > Cr > Pb > Cd > Hg respectively. Maximum accumulation of Mn (507.50 µg g -1 ) and Pb (0.51 µg g -1 ) in the gill tissues indicates the major uptake of these metals from the water column. According to the Hazard Index (HI) calculations (based on USEPA), the analyzed metals will not cause any harmful health effects to individuals for both normal and habitual fish consumers, except for Hg and As in habitual consumers, if these species are consumed at a larger amount. Compared to the Chinese Food Health Criterion and other international standards (WHO/FAO), metal concentrations in the edible muscle tissues of the studied species are lesser than the acceptable levels and found to be fit for human consumption.
