The symbol ug/dl is used to express what?

The symbol ug/dl is used to express what?

• A. Blood lead level
• B. Water lead concentration
• C. Air lead concentration
• D. Soil lead concentration

Answer: (A)

ug/dL is a concentration unit used to report how much lead is in a person’s blood. It expresses the amount of lead in a small volume of blood (one deciliter, or 100 milliliters), and blood lead levels are typically in the single to tens of micrograms per deciliter range. This makes it the standard way to assess exposure and risk in individuals, especially in children's health monitoring. Other media use different units (water is usually micrograms per liter, air is micrograms per cubic meter, soil is micrograms per gram or milligrams per kilogram), so the same symbol points specifically to blood lead level, not environmental concentrations.
