Suvremene metode remedijacije onečišćenog tla i vode

Pollution of the environment is one of the major problems of today. Main causes of pollution are anthropogenic and can be classified in three groups: waste water (industrial and agricultural, domestic, communal waste waters), atmospheric pollutants distributed to soil and water by precipitation or sedimentation (industrial emissions, fossil fuel combustion emissions, traffic emissions, emissions from landfills and waste incineration), and solid waste (communal, industrial, agricultural). The faith of pollutants, once they are deposited in the environment, depends on various physical, chemical and biological factors. Inorganic pollutants, unlike organic pollutants, cannot be degraded and are accumulated in the soil and sediment, what further complicates the problem. From the soil, they can enter the plants and participate in the food chain, or the can get into the ground waters, and eventually surface waters, where they pose a serious health threat. Hence, in order to improve current state of the environment and to stop further pollution nowadays different measures are applied (remediation). Modern day remediation methods can be generally grouped into four groups (biological, chemical, physical, thermal), but are often combined. Their main aims are to reduce the pollutant concentration at an acceptable level, isolate pollution, and reduce pollutant bioavailability. The choice of the technology depends on several factors, such as the type of the pollution, soil type and purpose, spatial component of the pollution (surface, volume, location, proximity of surface or ground water), and the time component of the pollution (time frame of exposure to the pollutant). Great significance have remediation technologies that allow preservation original form of soil, such as phytoremediation or electrochemical remediation. The aim of this study was to give an overview and analysis of advantages and disadvantages of advanced remediation methods for soil and water purification.
