Heavy Metals and Zinc Levels Roles in the Environment and their use on Higher Plants
Keywords:heavy metals, human exposure, toxicity, organ harm, zinc, plants
Natural elements with a high atomic weight and a density greater than five times that of water are known as heavy metals. They are widely disseminated in the environment due to their numerous industrial, household, agricultural, medical, and technical applications, raising worries about their potential effects on both human health and the environment. The dosage, method of exposure, chemical species, as well as the exposed person's age, gender, heredity, and nutritional status, all have an impact on how dangerous these compounds are. Arsenic, cadmium, chromium, lead, and mercury are among the priority metals of public health concern due to their severe toxicity. These metallic substances are regarded as systemic toxins that can harm different organs even at low exposure levels. The International Agency for Research on Cancer has classed them as human carcinogens as well. This study examines the prevalence, production, and usage of these chemicals in the environment as well as the possibility of human exposure and the molecular mechanisms of toxicity, genotoxicity, and carcinogenicity.
