Exposure assessment for nanomaterials presents unique challenges, including:
Detection Limits: Nanomaterials often exist at very low concentrations, making detection difficult. Aerosol Dynamics: Nanoparticles in the air can agglomerate, settle, or react, complicating measurement. Diverse Matrices: Nanomaterials can be present in various media, requiring different sampling and analysis techniques. Standardization: There is a need for standardized methods and protocols to ensure consistency and comparability of results.
