摘要: This study aimed to investigate the lead (Pb) and cadmium (Cd) concentrations in soil plants (medicinal fodder) grown chromite mining-affected areas, Northern Pakistan. Soil plant samples were collected analyzed for Pb Cd using atomic absorption spectrometer. pollution load indices (PLIs) greater than 2 both Pb, indicating high level of contamination area. Furthermore, surrounding mining sites exceeded maximum allowable limit (MAL) (0.6 mg kg(-1)), while lower MAL (350 kg(-1)) set by State Environmental Protection Administration (SEPA) agriculture soil. The significantly higher (P < 0.001) mining-contaminated as compared reference site, which can be attributed dispersion toxic heavy metals, present bed rocks waste mines. majority medicinal fodder species areas mines their MALs World Health Organization/Food Agriculture Organization (WHO/FAO) herbal (10 0.3 kg(-1), respectively) edible (0.3 0.2 plants. may cause food chain health risk.
