摘 要:In this Current Intelligence Bulletin, NIOSH continues its long-standing history of using the best available scientific information to assess potential hazards and risks and to provide guidance for protecting workers. Since it is early in the development of these materials and their applications, there is limited information on which to make protective recommendations. To date, NIOSH is not aware of any reports of adverse health effects in workers using or producing CNT or CNF. However, there are studies of animals exposed to CNT and CNF that are informative in predicting potential human health effects consistent with ways in which scientists traditionally have used such data in recommending risk management strategies. NIOSH systematically reviewed 54 laboratory animal studies, many of which indicated that CNT/CNF could cause adverse pulmonary effects including inflammation (44/54), granulomas (27/54), and pulmonary fibrosis (25/54) (Tables 31 through 38). NIOSH considers these animal study findings to be relevant to human health risks because similar lung effects have been observed in workers exposed to respirable particulates of other materials in dusty jobs (Rom and Markowitz 2006; Hubbs et al. 2011). There are well established correlations between results of animal studies and adverse effects in workers exposed to particulates and other air contaminants (NIOSH 2002, 2006, 2011a, b).
