measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...

Heavy metals that enter marine environment and remain in the water as well as the sediments are accumulated by aquatic organisms, thus becoming highly good indicators to monitor metal accumulation in the long run. Metals are potentially harmful to humans and most organisms at varied levels of exposure and absorption. Northern East Mediterranean Sea is a crucial region as it is an area, shared b...

One of the important abiotic stresses that negatively affect cereals such as wheat is heavy metals. Soil pollution with heavy metals has become one of the major environmental concerns resulting from the industrial development and use of fertilizers containing heavy metals. One way to counteract the negative effects of heavy metals in plants which produce reactive oxygen species is the activatio...

abstract heavy metals uptake and their distribution in plants are different. in addition to the genetic factors, environmental factors such as interactions of heavy metals with essential elements are very important on the amount of heavy metals uptake. in this study, the effects of iron and manganese on accumulation of cadmium in shoot and root of sunflower and corn in different concentration o...
