Indoor Air Quality Concerns in Building Materials: Formaldehyde, Asbestos, and Lead-based Paint

Name three substances/chemicals that may be found in buildings throughout the Easton, PA area that are not considered under the guidelines of ASTM 1527.

1. Formaldehyde: Formaldehyde is a common chemical found in building materials such as particleboard, insulation, adhesives, and some paints. It is not specifically included in the guidelines of ASTM 1527 for Phase I Environmental Site Assessments (ESAs) but may be a concern for indoor air quality and potential health effects.

2. Asbestos-containing materials: While ASTM 1527 does address the potential presence of asbestos-containing materials (ACMs), it may not always be included in the scope of the assessment depending on the age of the building and when the materials were installed. ACMs can be found in older insulation, flooring, roofing, and other building materials.

3. Lead-based paint: Similar to asbestos, lead-based paint may not be included in the scope of ASTM 1527 assessments unless it is known or suspected to be present in the building. Lead-based paint was commonly used in buildings constructed before 1978 and can be a hazard to human health, especially young children who may ingest lead paint chips or dust.
