What compound is used to measure cumulative exposure to lead?

  1. Blood lead level

  2. Urine lead level

  3. K-wave X-ray fluorescence

  4. Delta-aminolevulinic acid

The correct answer is: K-wave X-ray fluorescence

K-wave X-ray fluorescence is a non-invasive and accurate technique used to measure the amount of lead in the bone, which is an indicator of long-term exposure to lead. This is why options A, B, and D are incorrect. Blood and urine tests can only measure recent or short-term exposure, while delta-aminolevulinic acid is a byproduct of lead exposure and not a direct measurement of cumulative exposure.
