US Bundesbehörde NIOSH

NIOSH has recommended an occupational exposure limit of 1 µg/m3 for carbon nanotubes and carbon nanofibres.

 

The US authority NIOSH has recommended that occupational exposures to carbon nanotubes (CNTs) and carbon nanofibres (CNFs) need to be controlled in order to reduce the potential risk of certain work-related lung effects. CNTs and CNFs are man-made elongated particles made of sheets of pure carbon that are approximately a thousand times smaller than a human hair.

NIOSH's recommendations are summarised in the technical document „Current Intelligence Bulletin No. 65: Occupational Exposure to Carbon Nanotubes and Nanofibres“. They are based on peer-reviewed findings from NIOSH laboratory studies, field observations of industrial processes, intensive review of published studies by other research authorities, and public review and comment on an earlier draft of the document.

Recent results from experimental animal studies with rodents indicate that exposure to CNTs and CNFs may pose a respiratory hazard if inhaled. NIOSH's recommendations are expected to assist industry in establishing good risk management practices for controlling occupational exposures to free, unbound CNTs and CNFs during their manufacture and industrial use.
