Overview

This project examined the effects of PM exposure in senescent (elderly) rats, using a laboratory-generated mixture of ammonium nitrate and elemental carbon (carbon black). Senescent rats exhibited changes in blood pressure and heart rate variability that were consistent with an adverse effect of PM on the heart. Humans and rats, exposed under similar conditions, both exhibited increased activation of macrophages. The results provided evidence of decreased heart rate variability after the exposures. This effect was also noted in the work conducted at UCSF by the previous speakers.
