Heavy Metals

 Heavy metals are natural components of the crust. They can't be degraded or destroyed. To little extent they enter our bodies via food, beverage and air. As trace elements, some heavy metals (e.g. copper, selenium, zinc) are essential to take care of the metabolism of the physical body. However, at higher concentrations they will cause poisoning. Heavy metal poisoning could result, as an example, from drinking-water contamination (e.g. lead pipes), high ambient air concentrations near emission sources, or intake via the organic phenomenon . Heavy metals are dangerous because they have a tendency to bio accumulate. Bioaccumulation means a rise within the concentration of a chemical during a biological organism over time, compared to the chemical's concentration within the environment. Compounds accumulate in living things any time they're haunted and stored faster than they're weakened (metabolized) or excreted. Heavy metals can enter a water system by industrial and consumer waste, or maybe from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers, and groundwater. Antimony may be a metal utilized in the compound antimony trioxide, a flame retardant. It also can be found in batteries, pigments, and ceramics and glass. Exposure to high levels of antimony for brief periods of your time causes nausea, vomiting, and diarrhoea. There’s little information on the consequences of long-term antimony exposure, but it's a suspected human carcinogen. Most antimony compounds don't bioaccumulate in aquatic life.
