Effect of heavy metal aluminum (AL) on antioxidative enzyme activities and growth and oxidative stress in wheat crop
Author(s): Dr. Ashok Kumar
Abstract: Heavy metal accumulation is one of the most significant agronomic challenges that poses a serious hazard to food safety. Due to these issues, soil biologists and agronomists have recently voiced concerns regarding heavy metal pollution, which is negatively impacting agroecosystems and crop production. When toxic heavy metals are deposited in excess of permissible limits, they adversely affect the density, composition, and physiological activities of microbiota, as well as the dynamics and fertility of the soil, ultimately resulting in a decrease in wheat production and, via the food chain, human and animal health. In order to preserve the physiological activities of microorganisms, the nutrient pool of soils, and wheat production in an environment that is continuously deteriorating, the metal-induced phytotoxicity issues require immediate and urgent attention. The accumulation of heavy metals is currently one of the most severe environmental issues, not only because many of these metals are toxic to crops, but also because of their potential to harm animals and humans. Metals are non-biodegradable and regarded as significant environmental pollutants, causing cytotoxic, mutagenic, and carcinogenic effects in animals. The accumulation of heavy metals in plants occurs in both roots and aboveground tissue, so there is considerable interest in monitoring the bioavailable reservoir of metals. Wheat is one of the most important commodities and an essential part of the national diet. It provides carbohydrates, proteins, and specific inorganic micronutrients, all of which are essential to human growth. Consumption of grain is secure when the accumulation of metals falls below the allowable thresholds. However, when concentrations exceed the allowable limit, it exerts toxic effects and may cause a variety of human diseases. Historically, the study of heavy metal pollution concentrated on industrialized regions.
