A review of ecological risk assessment and associated health risks with heavy metals in sediment from India
Abstract Heavy metal (HM) pollution in sediment is a serious concern particularly in developing nations, warranting an extensive survey to understand the current situation and propose possible remedial measures. This paper compiles the data of HMs cadmium (Cd), iron (Fe), cobalt (Co), manganese (Mn), arsenic (As), lead (Pb), chromium (Cr), copper (Cu), zinc (Zn) and nickel (Ni) in aquatic sediment from India from 1979 to 2017. It was found that mean values of Cu, Co, Zn, Pb, As, and Cr in Indian sediment were high in comparison to the Australian Interim Sediment Quality Guidelines, World Surface Rock Average, and the Threshold Effect Level for freshwater ecosystems. Anthropogenic activities…
Ecological and human health risks appraisal of metal(loid)s in agricultural soils: a review
Agriculture is one of the major human activities that changed the landforms, water resources and the biogeochemical cycles. Pollution of agricultural soilsby metal(loid)s is a serious and global hazard but worldwide studies related to metal(loid)s pollution in agricultural soils are very limited. To fulfil this gap, metal(loid)s content in agricultural soils from 2001 to 2019 all over the world was reviewed. Multivariate statistical techniques, contamination indices and human health risk assessment were determined for the metal(loid)s. Among the analysed metal(loid)s, the average contents of Zn, Cu, Pb, Cr, Cd, As and Ni exceeded the Canadian, and China soil guidelines limits. The results o…
Combination of contamination indices and ecological risk assessment index for evaluation of pollution level in sediments
Abstract Sediments act as the key storehouse of heavy metals (HMs) and play a vital function in the transport and potential discharge of HMs. Lower basins and agricultural areas are frequently inundated with various pollutants from different origins, which are categorized as constant, bioaccumulative, and unsafe pollutants. Moreover, the unrestricted development of urban and rural parts of developing countries has a great influence on water quality and ultimately on sediments. The human contributions to HM pollution and allied ecological and health risks are discussed in this chapter. Also in this chapter, details of the single pollution indices and multiple pollution indices are described.…
