“…Our results were consistent with the DIM concentration for Cd (0.001) reported by Chaoua et al [26]. Chen et al [50] showed a range for Cd (0.0001-0.0029), which is greater than the current results but lower than DIM values for Cd in different feeds, which varied from 0.0000527 to 0.000149 found by Khan et al [27]. According to the current study's copper DIM concentration range of 0.0053 to 0.0140, which was lower than 1, there is no harm to animals' health from forages grown in polluted soil.…”

Heavy metals pollution is a major concern on a global scale. The present work evaluated the cadmium (Cd) and copper (Cu) concentrations in water, soil, forages (Avena sativa, Brassica campestris, Medicago sativa, Pennisetum glaucum and Trifolium alexandrinum), milk and hair samples of cows. The samples taken according to trophic levels of the food chain were collected from selected arid regions of Khushab, Punjab, Pakistan and analyzed by an atomic absorption spectrophotometer. The concentrations of Cd and Cu were found in the range of 0.041-0.065 mg/L, 0.585-1.341 mg/L in water; 0.223-2.600 mg/kg, 11.550-15.853 mg/kg in soil; 0.0037-0.682 mg/kg, 3.0917-8.208 mg/kg in fodder; 0.0457-0.137 mg/kg, 0.0167-0.690 mg/L in milk and 0.043-0.112 mg/kg, 0.0427-0.497 mg/kg in hair, respectively. The Cd and Cu concentrations in water, soil, forage, milk and hair were safer compared to standard limits. Bioconcentration factor (BCF), Enrichment factor (EF), Daily Intake of Metal (DIM), and Health Risk Index (HRI) were found less than 1 in Cd and Cu whereas PLI<1 in Cd and PLI>1 in Cu that indicates copper pollution in soil. So, regular monitoring of heavy metals was required to appraise contamination levels in the environment.

“…The lowest Cd level was examined in all soil specimens in contrast to the amount (11.22 mg/kg) revealed by Chaoua et al [26]. Khan et al [27] revealed a larger range of cadmium in soil than previous findings. The current value of copper in soil irrigated by groundwater showed a variation from 11.550 to 15.853 mg/kg.…”
