The exposure to and health effects of antimony
Exposure to antimony concentrations of 9 mg/m 3 of air will result in eye, skin, and lung irritation. Long-term exposure to antimony in smelting plants may result in the formation of antimoniosis, a particular form of pneumoconiosis. Chronic exposure will potentiate lung, heart, and gastrointestinal diseases.

A novel method to determine trimethylantimony concentrations in plant …
Environmental context Antimony enters the soil mostly through mining and shooting activities and can thereafter be taken up by plants. In the soil, antimony may undergo several transformations such as biomethylation, leading to the formation of trimethylantimony. Here, we measured for the first time the uptake and translocation of …

Antimony Toxicity
The concentration of antimony in air ranges from a nanogram per cubic meter (ng/m 3) to about 170 ng/m 3. The concentration of antimony that is found dissolved in rivers and lakes is usually less than 5 parts of antimony in 1 billion parts of water (ppb) and it is found attached to particles of dirt.
