The unit ug/dL measures lead concentration in which sample?

Explanation:
Micrograms per deciliter is a unit used for concentrations in blood. Lead testing in people is done with a blood sample and reported as µg/dL because it reflects the amount of lead relative to blood volume and helps assess exposure and toxicity in a clinical context. Other sample types use different units: water is usually reported in µg/L (or ppb), air in µg/m³, and soil in mg/kg (or ppm). So this unit specifically indicates a blood lead measurement.
