Study of copper, cobalt, molybdenum and zinc content correlated with pH in Banat region rego-soil samples

摘要

The soil is that specific part of the earth's crust was all the biological and biochemical processes are in continue development. It is an open dynamic system with own ability, what is depending on variable energetically flux received from the universe. Heavy metals can have a pollutant effect on the soils and plants. Parts from these metals are considered micro-elements, with an important role in growing of plants and nutrition for animals and humans. These micro-elements can become toxic if they outrun the limit. Every ware in Banat region the heavy metal content is higher then the admitted value, but still we cannot consider this region as a polluted region, because the values are under the threshold alert value, but anytime this values can be undertaken by not giving maximal attention to the environment and taking real precaution.
