According to safety standards, what level of lead in blood is considered hazardous?

The level of lead in blood considered hazardous is established by health authorities to protect public health, especially for vulnerable populations such as children and pregnant women. A blood lead level of 10 micrograms per deciliter (µg/dl) is recognized by the Centers for Disease Control and Prevention (CDC) and other health organizations as the action level that triggers public health interventions. At this level, there is substantial evidence linking lead exposure to harmful health effects, including cognitive impairments in children and various health issues in adults.

Interventions are typically recommended when levels reach or exceed this threshold, including blood lead screenings and possible referrals for further evaluation or lead exposure reduction methods. Higher levels, such as 15 mg/dl or 20 mg/dl, signify increased health risks, but the definitive action level for intervention remains at 10 mg/dl.

Understanding these levels is crucial for effectively managing and mitigating lead exposure risks in various environments, particularly in occupational settings and homes.
