Abstract: Uninterrupted generation of fly ash by the coal based thermal power plants and its dumping has lead to steady encroachment of useful land in India. The deleterious effects of fly ash on the nearby environment are inevitable due to its fine texture and presence of toxic metals. Agriculture application is one of the several options available for the disposal of fly ash, a hazardous solid waste generated from coal based thermal power plants. Fly ash contains both micro- and macro nutrients useful for plant growth. However, it also contains toxic heavy metals which can move to the plants and accumulate resulting in toxicity to plants and animals. Accumulation of metals in plant parts having secondary metabolites, which is responsible for a particular pharmacological activity. The issue of heavy metal pollution is very much concerned because of their toxicity for plant, animal and human beings and their lack of biodegradability. Excess concentrations of heavy metals have adverse effects on plant metabolic activities hence affect the food production, quantitatively and qualitatively. Heavy metal when reaches human tissues through various absorption pathways such as direct ingestion, dermal contact, diet through the soil–food chain, inhalation and oral intake may seriously affect their health. Prolonged exposure to heavy metals such as cadmium, copper, lead, nickel, and zinc can cause deleterious health effects in humans. This article attempts to highlight the use of fly ash bearing heavy metals and their problems.
