What level of lead does the EPA define as "dangerous" in household dust on window sills?

100 ug/ft2 (micrograms/square foot)
250 ug/ft2 (micrograms/square foot)
40 ug/ft2 (micrograms/square foot)
60 ug/ft2 (micrograms/square foot)

The correct answer is: 40 ug/ft2 (micrograms/square foot)

The Environmental Protection Agency (EPA) has established specific guidelines to identify hazardous levels of lead in household dust. The defining threshold for lead on window sills, particularly in residential settings, is set at 40 micrograms per square foot (ug/ft²). This level is significant because lead exposure can have serious health consequences, especially for young children and pregnant women, making it critical to monitor and manage lead contamination in homes. Setting the benchmark at 40 ug/ft² reflects the agency's commitment to minimizing lead exposure risks. It allows for the implementation of abatement or remediation measures before lead levels can potentially result in harmful health effects. Understanding this standard is essential for risk assessors and homeowners alike, as it underscores the importance of lead safety in residential environments. This benchmark not only aids in the identification of lead hazards but also informs public awareness efforts regarding lead risks in homes.
