What are heavy metals

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be. A heavy metal is a dense metal that is (usually) toxic at low concentrations. Although the phrase heavy metal is common, there is no standard definition assigning metals as heavy metals. Characteristics of Heavy Metals Heavy metals are a group of metals and metalloids that have relatively high density and are toxic even at ppb levels. Examples include Pb, As, Hg, Cd, Zn, Ag, Cu, Fe, Cr, Ni, Pd, and Pt. These metals are released into the environment by both natural and anthropogenic sources such as industrial discharge, automobiles exhaust, and mining

In science, a heavy metal is a metallic element which is toxic and has a high density, specific gravity or atomic weight. However, the term means something slightly different in common usage, referring to any metal capable of causing health problems or environmental damage. Examples of Heavy Metals The term heavymetal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury(Hg), cadmium(Cd), arsenic(As), chromium(Cr), thallium(Tl), and lead(Pb). Heavy metals are natural components of the Earth's crust Toxic metals, including heavy metals, are individual metals and metal compounds that negatively affect people's health. Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic Heavy metals are defined as metallic elements that have a relatively high density compared to water. 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 Mercury is a metal in liquid form at room temperature, often referred to as quicksilver for its silvery-white appearance. Mercury is very heavy. It weighs 13.6 times more than water in equal volumes. To put it in perspective: iron, stone, and lead can float on its surface

Heavy metals are generally referred to as those metals which possess a specific density of more than 5 g/cm3and adversely affect the environment and living organisms (Järup, 2003) Heavy metals are are elements that are naturally found in the earth. They're used in many modern-day applications, such as agriculture, medicine, and industry. Your body even naturally contains..
