Uptake of heavy metals by vegetables from fly ash amended soils
This study aim<XI to investigate the uptake of heavy metals by water spinach (Jpomoea aqua/lea) and chilies (Capsicum annum). These two types of vegetables were grown :in soil with fly ash amendments. Soil and fly ash samples were characterized for pH, organic matter. electrical conductivity, hea...
