Arsenic contamination has turned out to be a common phenomenon nowadays because it contaminates the extent of the area and directly or indirectly affects a large number of people across the world. The contaminant level has spread to soil and sediment from groundwater and various other natural sources.

It is one of the chemical characteristics of phosphate that can disturb some aspects of phosphate-dependent metabolism in all living forms. Arsenic can be transported across plasma membranes by phosphate transport proteins, leading to imbalances in phosphate intake. What actually happens during phosphorylation reactions is that arsenic competes with phosphate and forms unstable compounds that reduce the cell's ability to carry out its metabolism. A higher concentration of arsenic is deadly to plants. Arsenate, a salt or ester of arsenic acid, has been determined to be the dominant entity residing in soil and its similarity to phosphate allows it to compete for the same uptake transporters in the root plasma lemma. By thus intervening on metabolic processes, the inhibition of plant growth is achieved. It also includes inhibition of seed germination, decreased plant height, decreased root growth, minimized shoot growth, and decreased fruit and grain yields. The risk of human vulnerability to arsenic in soil has increased significantly in recent decades due to the expansion of land areas. dominion from previous lands used for agriculture. Continued fragility to arsenic causes many clinical aspects such as skin lesions, melanosis or hyperpigmentation, keratosis, leukomelanosis. The other health problems can be carcinogenic to skin, lung, bladder, liver and kidney cancer, carotid atherosclerosis and sometimes even heart disease. Additionally, it influences hormonal regulations through retinoic acid, thyroid hormone, and estrogen receptors. Please note: this is just an example. Get a custom paper from our expert writers now.
