Abstract

Different researches showed that contamination of heavy metals in soil has become more and more serious, which affects Both soil fertility degradation and detrimental to human health through food chain causing adverse effects on human health. The concentration of metals beyond Maximum Permissible Level (MCL) leads to number of nervous, cardiovascular, renal, neurological impairment as well as bone diseases and several other health disorders and also computed the macronutrient in the human body. Due to these it needs more attention towards the contamination area using either prevention or minimizing methods of the source of contamination. Different researches mentioned different remediation techniques which involve phytoremediation, lime, phosphates, and different biochar materials. Remediation mechanisms basically consist of two fundamental principles. The first is to completely remove contaminations from polluted area and the second is to transform these pollutants to harmless forms. The application of Biochar in soil makes dual purpose which ameliorating soil fertility and remediated heavy metal due to the content of different physicochemical properties. So in this paper, including source of heavy metal, effect of heavy metal in human, plant growth and soil microorganism and remediation technique of contaminated soil, reaction of biochar in soil and application of biochar in soil quality were discussed. Therefore this is particular importance as it indicates the value of biochar as alternative remediation and amendments to ameliorate soil nutrient and acid soils for small-scale farmers who cannot afford to regularly purchase lime and mineral fertilizers as compared to phytoremediation techniques. But phytoremediation wide scope of area use of plants to partially or substantially remediate selected contaminants in contaminated soil, sludge, sediment, groundwater, surface water, and wastewater.

AB  - Different researches showed that contamination of heavy metals in soil has become more and more serious, which affects Both soil fertility degradation and detrimental to human health through food chain causing adverse effects on human health. The concentration of metals beyond Maximum Permissible Level (MCL) leads to number of nervous, cardiovascular, renal, neurological impairment as well as bone diseases and several other health disorders and also computed the macronutrient in the human body. Due to these it needs more attention towards the contamination area using either prevention or minimizing methods of the source of contamination. Different researches mentioned different remediation techniques which involve phytoremediation, lime, phosphates, and different biochar materials. Remediation mechanisms basically consist of two fundamental principles. The first is to completely remove contaminations from polluted area and the second is to transform these pollutants to harmless forms. The application of Biochar in soil makes dual purpose which ameliorating soil fertility and remediated heavy metal due to the content of different physicochemical properties. So in this paper, including source of heavy metal, effect of heavy metal in human, plant growth and soil microorganism and remediation technique of contaminated soil, reaction of biochar in soil and application of biochar in soil quality were discussed. Therefore this is particular importance as it indicates the value of biochar as alternative remediation and amendments to ameliorate soil nutrient and acid soils for small-scale farmers who cannot afford to regularly purchase lime and mineral fertilizers as compared to phytoremediation techniques. But phytoremediation wide scope of area use of plants to partially or substantially remediate selected contaminants in contaminated soil, sludge, sediment, groundwater, surface water, and wastewater.
