About Arsenic
Elemental arsenic does not occur naturally but its compounds are widespread, often occurring with metal-bearing ores and released during processing. It is widely used in timber preservatives and pesticides, and is well-documented as an occupational hazard.
The guideline for Arsenic is 0.3µg/m³ (24hr avg).
Arsenic is measured in micrograms per cubic metre.
