Abstract
In October 1996 the Association of Occupational and Environmental Clinics and the National Institute for Occupational Safety and Health (NIOSH) cosponsored an invited workshop on particulates not otherwise classified/ regulated (PNOC/R). As a basis for defining PNOC/R, and with the understanding that PNOR are those particulates without specific federal permissible exposure limits, the workshop used the American Conference of Governmental Industrial Hygienists' definition: Particulates Not Otherwise Classified (PNOC). There are many substances on the TLV list, and many more that are not on the list, for which there is no evidence of specific toxic effects. Those that are particulates have frequently been called "nuisance dusts." Although these materials may not cause fibrosis or systemic effects, they are not biologically inert.. . . Accordingly, the Chemical Substances TIN Committee recommends the use of the term "Particulates Not Otherwise Classified (PNOC)" to emphasize that all materials are potentially toxic and to avoid the implication that these materials are harmless...
