Abstract

In our study, we focused on urban wastewater management, with special regard to the problems caused by heavy metal contaminations. Heavy metals function at low concentrations as a biogenic element, but at the same time in higher amounts (especially above the limit value) are considered as pollutants. We determined the basic wastewater treatment problem: which is the main problem of heavy metal contaminated urban wastewaters and how could eliminate heavy metals. We focused on wastewater origin heavy metal mobility in environment and effect (risk) on human health. In the following, we undertook to analyse urban wastewater in this direction.
