Introduction of Asbestos:
Asbestos is a naturally occurring silicate fibre found underground or in rocks. It has distinct physical and chemical features due to which it is applicable on an industrial scale. Due to its commercial uses, 3000 different products are prepared from it. It is used as a loose fibre mixed with different materials include cement, plastic, and other resins, and makes the different cloth material including fire extinguisher suit or any other heat and electrically insulated tool, asbestos cement pipes, friction material, pipe covering, reinforced plastic and floor tiles.
Asbestos Entry in Atmosphere:
Asbestos fence removal in perth is naturally entered into the atmosphere. Chemical weathering of the rocks and the anthropogenic sources results in an increase in the amount of asbestos in the atmosphere. Anthropogenic sources include industrial wastes that are caused by human activities. Asbestos is non-volatile, thus can accumulate in the air. In the same manner, It can accumulate in the water when asbestos cement pipes become eroded. In soil, it can enter through the weathering of the asbestos-bearing rock.
In this manner, asbestos based in perth becomes a pollutant. It can be inhaled or ingested. If it gains entry into the human body, penetrates the lings and causes severe respiratory disorders including lung cancer.
Contaminated Land Remediation:
The contaminated land has become a major problem for many years. The major sources of this contamination are industrial waste, municipal waste, and other agricultural wastes. It was estimated that nearly 64% of the groundwater is badly affected in the urban areas due to these wastes. It means every year this contaminated waste prepare pathogens for the spread of disease. The contaminated land remediation provides a platform to make the soil again useable and fertile by cleaning its contaminants. These remedial techniques may be mechanical, chemical, and biological. The remediation involves the treatment of accumulated, mobilized, and toxic chemicals in the soil. The contaminated land remediation involves the containment, pump and treat, soil vapour extraction, solidification, soil washing, precipitation, bioremediation, and thermal desorption. Here we discuss some of the contaminated land remediation techniques:
- Containment:It is the most common method to handle contaminated land remediation. In this technique, a wall is constructed in the contaminated area to limit the use of this site.
- Pump and Treat:It is the primary technique used to clean underground water and soil. It consists of the pumping wells. The underground water is pumped in this technique and all the contaminants are removed by activated carbon, UV radiation, ozone treatment, and biodegradation. This technique is beneficial if contaminants are highly concentrated in the groundwater.
Soil Vapour Extraction:This is another technique of land contaminated remediation which is used to remove the organic and inorganic contaminants from the soil which are volatilized in nature. The wells are constructed in this method mostly made up of plastic. The volatilized contaminants which are in a gaseous state are gathered in the pipes or evacuated.
