1. 0.5 μg/m3

2. 1.0 μg/m3

3. 1.5 μg/m3

4. 2.0 μg/m3

The correct answer is: 1.5 μg/m3

The correct standard for lead in ambient air, as established by the California Department of Public Health (CDPH), is based on significant health considerations regarding lead exposure. The ambient air quality standard for lead, specifically measured as a 30-day average, is set at 1.5 μg/m3. This standard is critical to protecting public health, particularly for vulnerable populations such as children, who are more susceptible to the harmful effects of lead exposure. This standard is in alignment with regulatory guidelines that aim to reduce the risk of lead contamination in the environment, recognizing the toxic properties of lead and the importance of maintaining air quality to safeguard community health. Understanding this standard is essential for lead inspectors and assessors as they evaluate and monitor areas for lead contamination and work toward ensuring regulatory compliance and the protection of public health.
