This Published Document gives guidance on the development and implementation of plans and strategies for the assessment of exposure by inhalation of nanomaterials, based on an understanding of the nature of the exposure and the capabilities and limitations of exposure measurement instrumentation. It is applicable to all workplace settings in which nano-objects, including nanoparticles and nanotubes, are manufactured, processed or used. Sources of other data and information are also provided.

The Published Document describes a structured, step-by-step approach to exposure assessment which takes into account the purpose, the type of information needed, and the usefulness and limitations of the various approaches for exposure assessment for different types of nanomaterials, and provides a rationale for method selection.

This Published Document is intended to compliment the development and take-up of new nanotechnology-based materials in UK industry by providing manufacturers and users of these materials with effective strategies for assessing worker exposure to airborne nanomaterials.

Given the emergent nature of the knowledge base in this area, the guide is targeted at the professional user who already has some knowledge and experience of exposure assessment and occupational hygiene practice.
