Increased levels of transition metals like Fe, Ni, Cr, Hg and Pb are related to free radical generation, lipid peroxidation, DNA strand breaks and tumor growth in cellular systems. In order to evaluate the correlation to malignant growth in humans we investigated the accumulation of heavy metals in 8 healthy and 20 breast cancer biopsies by means of a standardized AAS methodology. A highly sign...

Excessive application of sewage sludge leads to the accumulation of potentially toxic elements in soils. The objective of this greenhouse study was to examine the DTPA–extractability of Fe, Zn, Cu, Mn, Pb, Cd, Ni, and Co in relation to soil pH and to investigate the concentrations of these metals in corn (Zea mayz). The study was conducted using a factorial experiment in a completely randomized...

 The concentrations of Cd, Pb, Ni and Hg were determined in gill, liver and muscle of Barbus xanthopterus in down streams of Karoon and Dez Rivers during summer 2009. Heavy metal concentrations varied significantly, depending on the types of the tissue in fish species. The levels of heavy metals such as Cd, Pb, Ni and Hg in the Barbus xanthopterus of Karoon River were higher than in Barbus xant...

Shrimps are one of the most important seafood sources for humans. Heavy metals accumulated in the body of shrimp can be transmitted to humans in the food chain. The present study was done in 2017 to compare the accumulation of heavy metals Copper (Cu), Iron (Fe), Lead (Pb), Cadmium (Cd), Tin (Sn), Arsenic (As) and Mercury (Hg) in edible tissue of Indian white shrimp in the fishing grounds of th...
