ASTM D8560-24 PDF

Overview

ASTM D8560-24, Standard Guide for Determination of Airborne PFAS in the Indoor Air Environment, establishes techniques for measuring per- and polyfluoroalkyl substances (PFAS) concentrations in indoor air. Recognizing the potential adverse health effects linked to some PFAS compounds, this guide provides best practices for sampling and analytical methods. It encompasses environments such as buildings, vehicles, and workplace settings, helping organizations and researchers perform accurate exposure assessments and risk analyses related to airborne PFAS.

This standard is developed by ASTM to align with internationally recognized principles, ensuring consistency and reliability in the determination of indoor air PFAS worldwide.

Key Topics

• PFAS Measurement Technologies: The standard outlines current technologies suitable for indoor air sampling, covering gas and particulate phases.
• Phase-Appropriate Methods: Not all PFAS share the same chemical properties; therefore, the guide emphasizes that sampling and analysis methods must be chosen based on the specific PFAS compounds, environmental conditions, and sampling objectives.
• Sampling Strategies: Describes both active and passive strategies, including sorbent-based approaches for compounds with molecular mass greater than 200 g/mol.
• Practical Limitations & Considerations: Offers guidance on advantages and limitations of various methods, stressing the importance of method suitability and quality control.
• Emerging Research: Recognizes rapid advancements in PFAS research and encourages regular review of methods as new information and technologies become available.
• Sources of Indoor PFAS: Identifies the variety of indoor PFAS sources, such as consumer products, building materials, food packaging, and infiltration from outdoor air, along with their typical inclusion in indoor dust.

Applications

• Exposure and Risk Assessment: Enables environmental health and safety professionals, building owners, and regulatory agencies to quantify PFAS concentrations in indoor air, which is vital for assessing potential human exposure and conducting health risk analyses.
• Indoor Air Quality Management: Supports the development of monitoring and mitigation strategies in indoor environments, especially in locations with known PFAS emissions or use of PFAS-containing materials.
• Research and Policy: Provides standardized methods for academic and industrial researchers investigating PFAS dynamics, sources, or mitigation. The guide also helps policymakers establish regulatory or voluntary indoor air quality guidelines involving PFAS.
• Workplace Safety: Assists organizations in evaluating workplace exposures in environments such as manufacturing plants, laboratories, or any site where PFAS may be present or processed.
