Sediments are usually regarded as the ultimate sink for heavy metals discharged into environment, and can be sensitive indicators for monitoring contaminants in aquatic environments. Therefore, the environmental problem of sediment pollution by heavy metals has received increasing attention in the last few decades in both developing and developed countries through the world. Environmental risk assessments, including sediment monitoring, are typical tools for supporting decision making in the regulatory context, an...

The removal of sulphate ions from different types of wastewater is an environmental challenge faced by several industrial sectors, such as the mining, petrochemical or metallurgical industry. Sulphates and heavy metals represent one of the main pollution sources is industrial effluents such as acid mine drainage (AMD) and other mining effluents. Manufacturing processes, primarily mining activities, often result in the production of effluents containing high amounts of inorganic pollutants e.g. heavy metals or sulp...

Anthropogenic activities produce a lot of chem ical, physical and bi ological pollutants, which penetrate by different ways into environment and influence the living organisms and ecosystems negatively. In present it does not exist universal method for environmental risk assessment. Most countries use various procedures in field of risk analysis oriented to the specific problem solutions close connected with the chosen factors, which have negative influences on the individual environmental parts. The paper deals w...
