Particulate matter (PM) is a serious threat to human health. Short-term exposure to high levels of this pollutant is just as dangerous as long-term exposure to high or low levels. There are no safe levels of exposure because PM exposure health effects are cumulative. How so?PM health risks associated with dune dust are primarily from inhaling airborne particles that are 10 micrometers or smaller. These very small particles are trapped in the lung. Particles that are not dissolved are absorbed into the lining of the lung. This causes scar tissue that over time can accumulate enough to impair lung function. The smallest particles can pass through the lungs into the blood stream, affecting organs. Exposure to PM pollution has been shown to increase incidents of lung impairment, heart disease and cancer in exposed populations, and to aggravate existing lung health problems.

Reports on a study that is the first large epidemiological analysis to examine the possible impact of PM2.5 exposure on the development of chronic kidney disease (CKD) and end-stage renal disease (ESRD).
