LEAD (Pb) ACCUMULATION STUDY IN PLANTS AND VEGETABLES CULTIVATES AROUND COAL MINES AND POWER PLANT OF SINGRAULI DISTRICT

The study of undertaken for heavy metal Pb accumulation by fly ash and coal waste in Singrauli industrialised district of India, using atomic absorption spectrometry. Ashes from collected vegetables and plants leaves samples were analysed for the quality and quantity of Cr, Mn, Pb, Zn, Cu, As, Ni and Co and detectable levels of all were found. Pb distrusted the metabolic processes of living organisms due to variable accumulation in plants and vegetable which affected the human populations through food chain. Presence of Pb and other heavy metals in environment has become a major threat to plant and common vegetable due to their bioaccumulation tendency and toxicity. In present investigation 6 plants leaves Syzygium Cumini, Dalbergia Sissoo, Dandrocalamus Strictus, Magnifera Indica, Tectona Grandis and Azadiracta Indica and 6 common leafy vegetables Spinacia Olaracia, Solanum Tuberosam, Raphanus Sativus, Brasica Comprestis, Trogonella Fonium and Momordica charantia were studies for monitoring or observation of current status of Pb in these plant and common vegetable species growing around the industries of Singrauli district. The Soil profiling were also performed for presence of heavy metals with specificity of quality, resulted indication was observed an alarming situation in Singrauli district of India. INTRODUCTION: Fly ash is produced as a result of coal combustion, thermal power station and discharged in ash ponds. Now-a-days fly ash disposal in environment is one of the major threats throughout the world. Production of ash depends on quality of coal, which contains a relatively high proportion of ash that leads to 10-30% ash formation . Discharged fly ash used in construction of roads, building and cement industries. The alkaline nature of ash has resulted in attempts at using it as fertilizer or amendment to enhance the fertility of soil. It contains several heavy metals along with low range of nitrogen and phosphorus and pH ranged from 4.5 to 12 depending on parental coal 2, . Ash is disposed by dry and wet method. Directly or indirectly both ultimately leads to dumping the fly ash on open land. Particles size of ash are very small to escape emission control devices and easily get suspended in air which toxic in nature to causes irritation in eyes, skin, nose, throat and respiratory tract. Therefore, disposal and utilization of ashes needs careful assessment to prevent of arable land into landfills and accumulation of toxic metals in soil . QUICK RESPONSE CODE IJPSR:
