Lead Monitoring

Inorganic lead exposure assessment — air and biological monitoring

Current WES
0.15 mg/m³
New WEL (Dec 2026)
0.05 mg/m³-67%

What Is Lead Monitoring?

Lead monitoring combines personal air sampling with biological monitoring (blood lead levels) to assess worker exposure to inorganic lead. Lead is a cumulative toxin causing neurotoxicity, anaemia, kidney damage, and reproductive harm.

The current WES of 0.15 mg/m³ TWA-8h will be reduced to 0.05 mg/m³ under the new WEL framework — a 67% reduction. Lead risk work triggers mandatory blood lead monitoring under WHS Regulations, with removal levels of 50 µg/dL (males) and 20 µg/dL (females of reproductive capacity).

How Is It Done?

Personal air sampling via IOM cassette or closed-face cassette. Analysis by ICP-MS or AAS. Biological monitoring via venous blood lead level (BLL).
