what are heavy metals
Heavy metals are usually high dense materials with high atomic numbers and atomic weights.These are toxic even in very low concentrations. With safer non-adjuvanted alternatives to aluminum-laden adjuvanted vaccines, as well as more judicious vaccine scheduling, hopefully fewer patients will develop AEs while still The environment and its compartments have been severely polluted by heavy metals. The term has been diversely defined, mostly in terms of density, relative atomic mass and atomic number. This diversity of definitions has raised questions about the nomenclature of these elements. Heavy metals are toxic to humans. Heavy metal refers to any metallic chemical element that has a high density and is toxic or poisonous at low concentrations. They are used in many modern-day applications like agriculture and medicines. ABSTRACTThe term ‘heavy metals’ is commonly used in the environmental literature to refer to metals and metalloids associated with environmental pollution, toxicity and adverse effects on biota. This has compromised the ability of the environment to foster life and render its intrinsic values. Heavy metals are known to be naturally occurring compounds, but anthropogenic activities introduce them in large quantities in different environmental compartments. Heavy metals are elements that can be naturally found in the earth. Heavy metals are typically considered heavy when they have a density ratio of 5:1 when compared with water. Heavy metals are the most commonly legislated chemicals globally. Learn about the symptoms, sources, diagnosis and treatment for heavy metal poisoning and toxicity. Coal contains many heavy metals, as it is created through compressed organic matter containing virtually every element in the periodic table - mainly carbon, but also heavy metals. The combination of the large number of available heavy metals and their toxic affects coupled with the vast array of uses for these metals has amounted to a number of different EU and international legislations which attempt to control and restrict their uses. Heavy metals are metallic, naturally occurring compounds that have a very high density compared to other metals--at least five times the density of water. The human body naturally contains some heavy metals. Heavy metals in vaccines and foods can cause deleteri-ous effects, ranging from mild to severe. The key difference between heavy metals and trace elements is that the heavy metals are usually toxic at very low concentrations whereas the trace elements are not toxic at low concentrations.. Heavy metals like lead and mercury are toxic and can make you sick. Zinc, iron, and copper. Heavy metals are metal elements that are categorized by their high density relative to other metals. All of which are necessary for the body to function correctionally. Many, but not all, heavy metals are considered toxic.
