Abstract


High levels of heavy metals, such as: lead, nickel, cadmium and manganese, which are present in soil and wastewater used for agricultural irrigation, are due to the fact that these metals can be accumulated into these systems, of main importance for agriculture. Because of its non-biodegradability features, toxicity effects onto several crops and consequences on their bio-availability, this may result hazardous. This literature survey highlights and remarks relative sensitivity of some plants before heavy metals presence and crops trend to accumulate them, emphasizing aspects related to some soil physicochemical characteristics and heavy metals phyto-toxicity.
