Learn about the symptoms, sources, diagnosis and treatment for heavy metal poisoning and toxicity. Among the abiotic stresses, toxic metal stress is one of the major threats to plant growth and development. Its exposure at higher rates disturbs the plant water and nutritional relations and causes oxidative damages to plants. Even though heavy metal tolerance in plants through microbial remediation has been investigated for many years, there is still considerable interest in extensive studies on plant–microbe–metal association due to their direct effects on enhanced biomass production and heavy metal tolerance (Glick, 2003; Taj and Rajkumar, 2016; Hansda and Kumar, 2017).

Deprivation of accepted resources is perhaps one of the lethal lapses mankind has ever prepared in its voyage of progress and civilization. Their presence is considered unique in the sense that it is difficult to remove them completely from the environment once they enter in it. Heavy metals entering plants can change the autioxidant enzyme activities, induce ROS production, and cause oxidative damage effects.

It can affect the central nervous function leading to mental disorder, damage the blood constituents and may damage the lungs, liver, kidneys and other vital organs promoting several disease conditions [ 6 ]. Heavy metals can damage and alter the functioning of organs such as the brain, kidney, lungs, liver, and blood. The heavy metal ions cause damage to the structural, enzymatic and non-enzymatic components of plant cell, often resulting in loss of cell viability, thus negatively impacting plant growth and development. chemical fertilizers, the heavy metal mediated chemical toxicity has become one of the major environmental threats for the plants around the globe.
