7 de oct. de 2021 · This review provides a synthesis of existing knowledge on the sources of heavy metals toxic for humans, such as arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), and nickel (Ni), and their impact on human health, with a special emphasis on toxic metals’ interactions with proteins.
1 de abr. de 2022 · Most heavy metals cause environmental and atmospheric pollution, and may be lethal to humans. Heavy metals can become strongly toxic by mixing with different environmental elements, such as water, soil, and air, and humans and other living organisms can be exposed to them through the food chain.
1 de sept. de 2020 · Heavy metals, such as copper, zinc, lead, cadmium and chromium, have been found in the soil of these agricultural lands at a high concentration [ 15, 16, 17, 18, 19 ]. Smelting causes localised pollution through atmospheric pollution, which then deposits on the soil.
15 de abr. de 2024 · Chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), mercury (Hg), zinc (Zn), and copper (Cu) are the main heavy metals.
Heavy metals are defined as metallic elements that have a relatively high density compared to water [ 1 ]. With the assumption that heaviness and toxicity are inter-related, heavy metals also include metalloids, such as arsenic, that are able to induce toxicity at low level of exposure [ 2 ].
15 de nov. de 2014 · The most commonly found heavy metals in waste water include arsenic, cadmium, chromium, copper, lead, nickel, and zinc, all of which cause risks for human health and the environment (Lambert et al., 2000). Heavy metals enter the surroundings by natural means and through human activities.
1 de ene. de 2011 · Because heavy metals are increasingly found in microbial habitats due to natural and industrial processes, microorganisms have evolved several mechanisms to tolerate their presence by adsorption, complexation, or chemical reduction of metal ions or to use them as terminal electron acceptors in anaerobic respiration.
