Tungsten Safety

Tungsten, once thought to be an environmentally friendly metal, may not be as safe as believed, researchers said. Today, we will talk about tungsten safety.

Tungsten is widely used in products ranging from bullets to light bulbs to jewellery. Scientists strongly held that tungsten is relatively insoluble in water and nontoxic.
In mid-1990s, the U.S. military adopts the so-called green bullets that contain tungsten as a more environmentally friendly substitude to lead-based ammunition.

While, new studies have shown that tungsten, which is also used in welding, metal cutting, is not as safe as thought. For example, exposure to tungsten would stunt the growth of plants, cause

reproductive problems in earthworms and trigger premature death in certain aquatic animals.
Both the U.S. Department of Defense and the Environmental Protection Agency have classfied tungsten as an emerging contaminant.
Although scientists think that tungsten seems less toxic, they do not know its exact healthy and environmental effects.
Whether or not tungsten would cause chronic health effects in human and our mechanism, it needs further study.
All information are about tungsten safety.
