The impact of heavy metal pollution on growth and water quality has become a public concern. Fractionation of soil lead (Pb) is an important approach of chemical characterization and can provide useful information on its bioavailability. A greenhouse study was undertaken to estimate the availability of Pb fractions to rice in two paddy soils of Inceptisol (Fluventic Umbrepts) and Ultisol (Plinthudic...
Nitric oxide (NO) is a free radical synthesized by nitric oxide synthase (NOS) during the conversion of l-arginine to citrulline. Lead (Pb) affects neuronal functioning in the rat brain. Nitric oxide, a neuronal messenger has a short half life and converts immediately into nitrite and nitrate. The present study is designed to determine lead-induced alterations in NO production by measuring nitrite...
