Once the harmful elements of arsenic, lead, copper, iron, and bismuth accumulate to some extent, we ...

You can also find tin antimony solder. Some 60 percent of all antimony produced today is used in the clothing and fabric industries in flame retardants, most often in its trioxide form, since the material inhibits combustion by reacting with oxygen and hydrogen atoms.

Antimony has no known biological function and the effects of long term human exposure are unknown. Antimony trioxide, a suspected carcinogen and listed as a priority pollutant by the US Environmental Protection Agency, is used as a catalyst in the production of polyethylene terephthalate (PET), which is used to package foodstuffs.

Antimony trioxide (Sb 2 O 3 ) is widely used to speed up synthesis of PET because it is efficient, presents a minimal tendency to produce side effects, and does not create colour in the polymer ...
