A current WHO guideline is 10 ug PM2.5/m3, but linear extrapolation is applied to the whole general pupolation. This leads to very high morbidity/mortality numbers (heart attack mortality, lung cancer incidence).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4705097374441454471.post-73645573412464230952014-06-25T19:43:21.508-04:002014-06-25T19:43:21.508-04:00If you got the above Power Point deck you will not...If you got the above Power Point deck you will notice that the references within it are somewhat dated and relatively limited. This is, they are certainly limited compared to the very thorough treatment given this subject by John Cherrie et al in a commentary published last year:<br />A Commentary for the Annals of Occupational Hygiene: Low-Toxicity Dust: Current Exposure Guidelines Are Not Sufficiently Protective. doi: 10.1093/annhyg/met083. This is a well researched piece with a very well developed argument for having the OEL at 1 mg/m3 at least for now. I found a free copy of it at: http://annhyg.oxfordjournals.org/content/57/6.toc<br />Mike Jayjockhttps://www.blogger.com/profile/02521885327730438390noreply@blogger.com
