The average daily zinc intake requirement from foods and supplements is 8–11 mg/day in adult [5] However, a large amount of zinc, along with other contaminated elements like lead and cadmium is emitted into the environment during the processing of zinc mining, triggering soil erosion, sinkholes, and the loss of biodiversity.
Characterization of Zinc, Lead, and Cadmium in Mine …
We characterized the lability and bioaccessibility of Zn, Pb, and Cd in size-fractionated mine waste at the Tar Creek Superfund Site (Oklahoma) to assess the potential for metal transport, exposure, and subsequent bioavailability. Bulk mine waste samples contained elevated Zn (9100 ± 2500 ppm), Pb (650 ± 360 ppm), and Cd (42 ± 10 ppm), while …
Cadmium, lead, and zinc mobility and plant uptake in a mine …
Pore water was sampled to assess the effects of biochar on zinc solubility, while soils were analyzed by DTPA extraction to confirm available metal concentrations. The application of BC decreased the available concentrations of Cd, Pb, and Zn in the mine contaminated soil leading to a consistent reduction in the concentration of Zn in the pore ...
