An experimental plot of soil contaminated with crude oil and heavy metals (copper, zinc and cadmium) was subjected to bioremediation using the activity of the indigenous soil microflora. The oil was light, rich in paraffins and with a very low content of asphaltene-resinous substances. Copper, zinc and cadmium were present mainly as sulfide minerals but also in forms more amenable to biological and chemical leaching. Their contents in the soil exceeded approximately 1.5-3 times the relevant… CONTINUE READING
