The concentrations were determined at 0-15cm and 15-30cm soil depths respectively and at 10m interval from the point of discharge of the POME. Soils at 100m away from the discharge point were regarded as normal or uncontaminated soils, while different extractants were used to determine the levels of Fe, Cu, Zn and Pb.

Smokers had higher blood Cu, Zn, and Cd than nonsmokers. There were significant age-related differences in blood levels of all metals studied; subjects in the 17–30 age group had higher blood levels of Mn, Pb, Cu, and Zn, while those in the 46–60 age group had higher Cd than the other age groups. A remarkably lower blood level of Cu and Zn ...

Effect of foliar applied Cd on Zn, Cu and Pb in wheat. The decreased Zn concentrations in wheat grain and elevated Zn concentrations in other components affected by the sprayed Cd solution (Fig. 3B) may imply that the Cd application made Zn in leaf, stem and glume less mobile. Thus, Zn is less likely to be transported to and deposited in wheat ...
