Heavy metal enrichment in soils has been linked to the weathering of lithologies with high
geochemical backgrounds, such as black shale. Therefore, this study conducted a typical …

The concentration and speciation of endogenous cadmium (Cd) in soil systems derived from
parent materials is continuously altered by rock-soil-plant interactions. Previous studies on …

Selenium (Se) is the essential component of selenoenzymes and contributes to antioxidant
defenses. The capability of Se to antagonize the toxicity of heavy metals makes it an …

Carbonaceous black shale generally contains high concentration of Cd, with weathering
leading to Cd release to environment. In this study, the mobility of Cd during weathering was …

The heavy metals in soils developed from the black rock series originate from the parent
rock, but their sources and enrichment mechanisms in the parent rock remain unclear. This …

In order to identify the source and bioavailability of soil Cd in the alluvial geological high
background area, 3799 topsoil samples and 140 root soil samples were collected from the …

Heavy metal (loid) s accumulation in soil-crop systems is associated with lithologies
weathering (black shales) a high geological background. To explore the heavy metal (loid) s …

Abstract Cadmium (Cd), a non-essential trace element for plants, is commonly found in the
environment due to human activities such as waste disposal, mining, metal manufacturing …

El cacao y el arroz son de los rubros más importante del sector agrícola ecuatoriano, sin
embargo, debido al manejo intensivo de los predios agrícolas, la inocuidad del producto …

The content of heavy metals, morphological characteristics, bioeffectiveness and the main
sources of heavy metal elements were analysed by using geostatistics, Risk Assessment …
