Which method can be used to identify hazardous lead levels in paint and soil?

X-ray fluorescence (XRF)
Visual inspection
Written surveys
Environmental impact assessments

The correct answer is: X-ray fluorescence (XRF)

X-ray fluorescence (XRF) is a highly effective method used to identify hazardous lead levels in paint and soil. This non-destructive technique allows assessors to determine the presence and concentration of lead in materials quickly and accurately without the need for sample collection or laboratory analysis. XRF instruments emit radiation that excites atoms in the material, causing them to emit fluorescent X-rays, which are then analyzed to detect elements, including lead. In contrast, visual inspection primarily relies on identifying signs of lead-based paint hazards such as chipping, peeling, or deterioration but cannot quantify lead levels. Written surveys might collect subjective data on the presence of lead but do not provide an accurate measurement of lead content. Environmental impact assessments evaluate the potential effects of proposed projects on the environment but do not specifically assess lead levels in paint or soil. Thus, XRF stands out as the most reliable option for directly measuring hazardous lead levels.
