HEAVY METAL TOXICITY, POLLUTION AND EFFECT ON PLANTS AND HUMAN BEING

Globally, environmental degradation is accelerating quickly. When present in soil, heavy metals including lead, cadmium, mercury, and iron pose serious environmental problems since they are harmful to both plants and animals and have a negative impact on human health. Even at very low concentrations, heavy metals are dangerous by nature and can seriously harm both people and animals. Industrial discharges and agricultural runoff are two ways that these heavy metals get into aquifer systems. To remove heavy metals from the aquatic environment, a variety of treatment methods are available, each with varying degrees of effectiveness. In any event, secondary waste creation, high operating and maintenance costs, etc. are the primary causes of a sizeable portion of these treatment systems' shortcomings. All across the world, vegetables are raised for human consumption as dietary supplements. Vegetable crops cultivated in environments with high levels of heavy metal contamination are the only ones where heavy metals accumulate; as a result, these heavy metals infiltrate the food chain. Humans that eat veggies tainted with heavy metals have a range of serious health problems. In addition to harming plants and animals, these heavy metals also have a detrimental effect on the health of the soil, water, and other aquatic life. To lessen the amount of heavy metals from various sources, there are numerous remediation techniques. This essay aims to analyse various heavy metal accumulations and their effects on pollution sources, people, and plants.
