  • Honey Bees, Bee-collected Pollen and Honey as Monitors of

    The largest values of Mn, Zn and Cu were obtained from forager bees, while the maximum values of Fe and Ni were found in bee-pollen. On the other hand, harmful elements including lead (Pb), cobalt (Co) and chromium (Cr) were not detected in any of the samples. From results obtained in this study, it can be concluded that heavy metal pollution was most intense in zones closest to the cement

  • DETERMINATION OF THE LEVEL OF SOME HEAVY METALS IN

    In view of this, levels of some heavy metals, Zn, Pb, Cr, Cu, Ni, Co, Ag, Fe and Mn were determined in water samples collected from two pollution prone areas around Kano (Sharada and Bompai industrial estates) and control site (Thomas Dam, Dambatta). The levels of the heavy metals were determined by Atomic Absorption Spectrophotometry. The results obtained show that the mean values of all

  • Sustainability | Free Full-Text | Heavy Metal Accumulation

    The pursuit of a good candidate to biomonitor environmental pollutants has been on the increase. In this study, the concentrations of Fe, Mn, Cu, Zn, Cd, Cr, Pb and Ni in sediment, seawater and seagrass Cymodocea serrulata compartments and antioxidant enzymes activities in C. serrulata were determined. Our results revealed that bioconcentration factors for all the metals were less than 1 (BCF
