US Rules and Regulations related to Elemental Species

The US Occupational Safety and Health Administration (OSHA) limits exposure to organoarsenicals in air. The permissible exposure limit (PEL) for organoarsenicals is 0.5 mg m3 as a time-weighted average  over an 8-hour period (29 CFR 1910.1000). The PEL (time-weighted average for 8 hours) for arsine (AsH3)  gas is 0.05 parts of arsine per million parts of contaminated air (ppm) by volume at 25 °C and 760 torr  (Appendix A), or about 0.2mg m3 (29 CFR 1910.1000). The PEL for inorganic arsenic is 10 µg m3 of  air as a time-weighted average over an 8-hour period (29 CFR 1910.1018). The action level for inorganic  arsenic in air is 5 µgm3 as a time-weighted average over an 8-hour period (29 CFR 1910.1018).
