What Is Lead Dust Testing?

Lead dust testing measures the amount of lead deposited on building surfaces using a wipe sample collected over a defined area.

Why Test Dust for Lead?

Measure surface contamination
Assess potential exposure
Check cleaning effectiveness
Monitor areas after building work
Identify potentially contaminated areas

👉 A potential source of contamination: lead in paint.

Regulatory Thresholds for Lead Dust

Results are expressed in µg/m², representing the amount of lead per square metre of sampled surface. They support post-work assessments when interpreted against the requirements applicable to the project.

👉 See: lead dust thresholds in France.

Wipe Sampling Method

Sampling is carried out over a defined, measured surface area using a suitable wipe.

👉 Sampling guidance: lead dust wipe sampling.

Lead Dust Testing Prices

The cost depends on the number of samples and the scope of the assessment.
