Abstract EN
Heavy metals known to be accumulated in plants adversely affect human health.
This study aims to assess the effects of agrochemicals especially chemical fertilizers applied in paddy fields, which release potential toxic heavy metals into soil.
Those heavy metals get accumulated in different parts of paddy plant (Oryza sativa L.) including the grains.
Concentrations of nonessential toxic heavy metals (Cd, Cr, and Pb) and the micronutrients (Cu, Mn, and Zn) were measured in the paddy field soil and plant parts.
Mn and Cd are found to be accumulated more in shoot than in root.
The metal transfer factors from soil to rice plant were significant for Pb, Cd, Cu, Cr, Mn, and Zn.
The ranking order of bioaccumulation factor (BAF) for heavy metals was Zn > Mn > Cd > Cu > Cr > Pb indicating that the accumulation of micronutrients was more than that of nonessential toxic heavy metals.
The concentrations of heavy metals were found to be higher in paddy field soils than that of the nearby control soil but below permissible limits.
The higher Health Index (HI) values of rice consuming adults (1.561) and children (1.360) suggest their adverse health effects in the near future.
