MicrosoftInternetExplorer4 Background and Objectives: Cyanide is a toxic pollutant existing in the various industrial effluents such as iron and steel, coal mining, non-ferrous metals manufacturing and metal plating. Its presence in water resources and wastewater, as serious hazardous substances leads to undesirable effects on both the environment and human. Thus, its concentration control...

The pollution caused by the presence of heavy metals in the air, water and soil is one of the world's ecological problems. In this study, the effect of different concentrations of calcium on the absorption and accumulation of Cd and Zn in M. flavida from Brassicacea was studied. For this purpose, concentrations of 100, 400 and 1600 µM calcium and 1, 5 and 10 µM Cd and 10, 20 and 40 ...
