What is the mandated maximum lead dust standard for window sills according to Title X?

The mandated maximum lead dust standard for window sills according to Title X is 100 micrograms per square foot (mcg/ft²). This standard is significant because it sets a threshold for the allowable concentration of lead dust in residential environments, particularly where young children may be exposed. The high sensitivity of children to lead exposure necessitates strict guidelines to reduce health risks associated with lead poisoning.

While there are lower standards established for other surfaces, such as floors or play areas, the window sill standard specifically focuses on areas where dust may accumulate and where children often come into contact with contaminated surfaces. Setting the standard at 100 mcg/ft² reflects a balance between practical cleaning guidelines and protective measures for public health, ensuring that property owners and lead risk assessors have clear criteria to evaluate and mitigate lead dust hazards effectively.
