The California Air Resources Board (ARB) released three new studies, that indicate exposure to airborne fine-particulate matter significantly elevates the risk of premature deaths from heart disease among older adults and elevates incidence of strokes among post-menopausal women. The third study examined platelets of mice exposed to PM2.5. This study found that the exposed mice showed platelet activation which could promote clotting and lead to stroke and heart attacks. These studies add to the existing scienctific evidence that respirable airborne particulates pose a threat to public health. If these particles pose a threat to public health, what about the threat to workers who are exposed to PM2.5 at their worksites?
These studies further support my call, for the requirement that workers wear respirators on all demolition and disaster sites.
