Bioaccumulation and Translocation of Heavy Metals in Solanum elaeagnifolium

Abstract

Heavy metal pollution is becoming an increasingly common problem. Heavy metals including Chromium, Cadmium, Mercury, Copper, and lead are hazardous environmental pollutants, especially in high anthropogenic activity areas. Heavy metals accretion in soil is a serious concern for agricultural productivity due to its negative influence on food safety, market potential, and the phytotoxicity it causes in crops. Plant ascendancy and metabolic processes affect the geological and biological re-distribution of heavy metals through air, soil, and water pollution. The typical result of heavy metals toxicity is excessive accumulation of reactive methylglyoxal and oxygen species, which lead to lipid peroxidation, enzyme inactivation, nucleic acid damage, and protein oxidation in plants. In this study, bioaccumulation and Translocation of Heavy Metals in Solanum elaeagnifolium was conducted by using standard biological techniques. Twenty-four samples of both shoot and root systems collected ‎from the study sites and Three replications of soil samples from each habitat, including topsoil (0-50 cm depth) were studied.our results showed that the quantitative concentration of heavy metals in the shoots of S. elaeagnifolium for each metal indicated a high enrichment value for (Cr), (Fe), and (Mn), on the other hand, it showed low enrichment values for (Ni) & (Pb). In addition, the concentration of heavy metals in the roots of the plant was differentiated.
