Contamination by heavy metals has attracted increasing attention considering the ability of these elements in producing serious consequence to ecosystem, and especially on animals health. Due to their widespread use in human activities such as industry, agriculture and even as medicine (e.g. arsenic, selenium and platinum), numerous health risks may be associated with exposure to these substanc...

materials and methods a total of 40 different bread types such as barbari, sangak, lavash, and baguette produced in 124 bakery shops in rasht city were analyzed for some heavy metals (as, cd, pb, cr, ni, and co) by inductive coupled plasma (icp) instrument (icp-qes). results the mean content of the as, cd, and pb in different breads were respectively as follows: barbari, 0, 0.73, and 0.07; sang...

Heavy metal concentration in the soils and sediments has increased worldwide during the last century due to the mining, smelting, and industrial activities. The Forumad chromite deposit is located in the Sabzevar ophiolitic complex (SOC), with a long history of mining activities, yet very little is known about the heavy metal contamination in its surrounding environment. In this research work, ...
