Evaluation of some factors influencing on variability in bioaccumulation of heavy metals in rodents species: Rombomys opimus and Rattus norvegicus from central Iran
Effects of some factors on concentrations of HMs in rat and gerbil were quantified. There were differences in HMs concentrations within and between species and sites. There were significant differences in Cd and Pb levels between male and female rats. Our findings suggest that hair cannot be used alone for monitoring exposure of HMs.
