The amount of lead found in the blood sample may be measured in micrograms of lead per deciliter of blood (μg/dL) especially in the United States; 5 μg/dL is equivalent to 0.24 μmol/L . [6] BLL cannot measure long-term lead exposure.
Lead poisoning is most commonly caused by breathing in lead dust or particles, but it can also occur by touching a surface where lead is present, then touching one’s nose or mouth, thereby ...
Many unknowingly consumed lead-contaminated water, which can have long-term negative health effects.
