Assessment of heavy metals bioaccumulation in some leafy vegetables grown in Kwakwachi Fagge Local government area, Kano state.

Abstract

The problem of Irrigation practices using waste water in the study area poses a public health concerned. The wastewater forms about 80-95% of the mass of plants (Singh et al., 2001 Hanif et al., 2006). In spite of containing essential plant nutrients as N, P, K, Ca, Mg and Fe which are important for plant growth, wastewater also contains a variety of inorganic substances from domestic and industrial sources, including potential toxic elements and heavy metals Pb, Cd, Ni, Cr and Hg (Sharma et al., 2006) which may be at phytotoxic levels or originate health risks (Pereira et al., 2002 Murtaza et al., 2010). Consequently, the usage of wastewater for irrigation ends to soil contamination and heavy metals accumulation both in soil and crops (Bigdeli and Seilsepour, 2008 Zulfqar et al., 2012)..
