    and Zn ranging from 20 to 990mg kg1 for Cu and from 195 to 2200mg kg1 for Zn (Table 1). Metal concentrations in the soil samples collected from different locations were highly correlated with r=0.72 (CuZn p<0.05 N=10) 0.84 (PbCu p<0.01 N=10) and 0.9 (PbZn p<0.01 N=10) respectively. This means a site that had a high Pb

  • Heavy Metal (Pb Zn Cd Fe and Cu) Contents of Plant

    Mining and processing of lead (Pb)/zinc (Zn) ore at the Anvil Range mine occurred near the town of Faro in the Yukon Territory Canada for approximately 30 years beginning in 1968. A study was undertaken to examine whether the mining activities had left a detectable footprint on the environment in the way of heavy metal phytoaccumulation.

    Sep 15 2006· In this study a total of 36 plant samples of 17 species was collected from 10 locations at the site. Concentrations of Pb Cu and Zn in soils and plant biomass are provided in Table 2 Table 3 Table 4.Total Pb concentrations in the plants ranged from non detectable to as high as 1183 mg kg 1 with the maximum being in the roots of Phyla nodiflora from site 4 ().

    The milk used in plant A contained higher amount of Pb Fe and Zn than the milk used in plant B. Pb level during processing in both dairy plants showed a signicant increase from milk to curd (626.2912.3 mg/kg for plant A and 265.2371.8 mg/kg dry weight for plant B) (P < 0.01). Similarly Fe Cu and Zn contents of the curds

  • Variability and relationships between Pb Cu and Zn

    Jun 06 2014· Concentrations of Cu in the litter leachate were correlated with dissolved organic C (DOC) whereas Zn and Pb were mainly related to leachate pH. Metal concentrations in the soil solution were weakly influenced by their total content in soils and the monthly fluctuations reached 300 600 and 700% for Cu Pb and Zn respectively.
