Effects of heavy metal pollution on the soil microbial activity
The effects of heavy metals on soil microbial processes were investigated over a period of six weeks. Analytical grade (Sigma) sulphate salts of copper, zinc and nickel were added individually and in combinations to soil samples and incubated in different plastic pots. Samples were taken from the pots forthnightly and the rates of microbial carbon and nitrogen mineralization, microbial biomass ...
متن کاملEvaluation of Heavy Metal Pollution in Anzali Wetland, Guilan, Iran
Background: Evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. Methods: In this study, total an...
متن کاملHeavy Metal Soil Content as an Indicator of Pollution
Two soil sample series were collected from 7 contaminated sites situated along a transect from the pollutant source, Zlatna copper ore-processing plant, and analyzed using different analytical methods. The soils collected in 1998 were analyzed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after extraction with DTPA for trace metals and those collected in 1999 were analyze...
متن کاملCadmium As An Heavy Metal Contamination of Food
SUMMARY Though cadmium has come into widespread use only relatively recently it is quite likely that for many countries this highly toxic metal has been causing food poisoning. Even minute amounts of cadmium are sufficient to cause poisoning and since the metal is soluble in organic acids; It easily enters food stuffs. The extreme danger resulting from ingestion of cadmium in food was high lig...
متن کاملAn improved fuzzy evaluation method for heavy metal pollution
The heavy metal is not easily degradable, the heavy metal pollution of water is the most harmful pollution for the environment, so, to evaluate the pollution grade is very important for pollution controlling. The fuzzy evaluation method is the most important way to evaluate the degree of pollution today. But in some case, one key factor of heavy metal will decide the pollution level, but the cl...
