Uptake of copper and cobalt by pumpkin (cucurbita maxima) and chinese cabbage (brassica oleracea) irrigated with contaminated water on sandy loam and clay loam soils.
Pumpkins and Chinese cabbage are widely grown in peri urban areas with different soil types in Zambia using waste water which is potentially contaminated with heavy metals like copper and cobalt. The objectives of this study were to establish the effect of loading rates of heavy metals on sandy and …
