Which two methods are commonly used to sample lead in paint?

The two methods commonly used to sample lead in paint are XRF analysis and laboratory analysis of paint chips.

X-ray fluorescence (XRF) analysis is a non-destructive testing method that provides immediate results regarding the presence and concentration of lead in paint. It uses a handheld device that emits X-rays, which interact with the elements in the paint, enabling the identification of lead content quickly and efficiently without the need to take physical samples.

Laboratory analysis of paint chips involves physically collecting samples of the paint from a surface and sending them to an accredited laboratory for detailed quantitative analysis. This method provides accurate measurements of lead levels and is crucial when there's a need for definitive data to inform risk assessments or abatement decisions.

While the other options include methods that relate to environmental safety and potential lead exposure, they do not specifically pertain to the analysis of lead in paint. Visual inspections and home testing kits may provide preliminary information but are not as reliable or precise as the XRF and laboratory analysis methods. Soil analysis and air quality testing, as well as water sample testing and dust wipes, focus on lead exposure from different sources and mediums rather than directly assessing lead in paint. Hence, the most appropriate methods for sampling lead in paint are accurately represented by the combination of
