Evaluation and control of occupational health risks from nanoparticles

image of Evaluation and control of occupational health risks from nanoparticles

Rapid growth in the nanoparticle industry is anticipated in the Nordic countries owing to highly focused national research and investment initiatives. Knowledge on consequences for occupational exposures to engineered nanoparticles and appropriate technical control levels is still limited. This report explores existing knowledge on exposure risks and technical control approaches. The report concludes that data are too limited to allow general conclusions to be drawn regarding risks of exposure to engineered nanoparticles. Engineering techniques for controlling nanoparticle exposure can build on the current knowledge and approaches to control exposure to e.g. welding fume and carbon black. There is a need for improving the quality of information provided in Material Safety Data Sheets.

Workplace exposure data

There are currently no national or international consensus standards on measurement techniques for nanoparticles at the work place. Thus, the occupational hygiene community has been hesitant initiating comprehensive monitoring. Hitherto, most ultrafine particles have been quantified by one or several of the methods condensation particles counters (measures total particle concentration in a size range of typically 10-1000 nm), electrical mobility analyzers, electrical low-pressure impactor, and others.
