Particulate Matter

Researchers at the Keck School of Medicine and the University of Southern California have just published a report in the American Chemical Society's Environmental Science & Technology journal that shows air traffic from Los Angeles International Airport is responsible for more air pollution than half of all the city's notoriously congested freeways with a plume extending […]

Over the last decade we've seen plenty of studies linking air pollution, and specifically Particulate Matter, or soot pollution, to heart disease and attacks. Now Dr. François Reeves,a Canandian cardiologist has a new book "Planet Heart: How an Unhealthy Environment Leads to Heart Disease," that puts those studies in context. “You can sum it up […]

One of the areas of environmental health research that's producing almost monthly results is the varied and pernicious adverse human health effects of tiny particulate matter, or soot. Once only blamed for respiratory problems and then heart attacks, it's now associated with a high blood pressure, strokes, immune system damage and a wide range of […]

We're a bit behind the curve in reporting on this, but scientists at the University of North Carolina just published a study in "Environmetnal Research Letters"  that estimates Particulate Matter and Ozone pollution in the air is responsible for approximately 2.2 million deaths worldwide every year.  Long-timers already know about how insidious Particulate Matter can […]

In an opinion piece in The Daily Climate, Michael MacCraken, the chief scientist for the DC-based Climate Institute advocates an end-run strategy to avoid the political logjam over large CO2 cuts as a way to fight global warming. He suggests concentrating on reducing Methane and Particulate Matter pollution as a way to "appreciably slow the […]

Does Pollution Discriminate?

Yes. Or rather the forces that shape where pollution and people co-exist. Historically we know that low-income and non-white urban areas are more likely to have polluting factories, Superfund Sites and illegal dumping. In large part, this is because the places within a city where "undesirable" heavy industries were allowed to locate were also traditionally […]

EPA Interpretation of Soot Regs Under Fire

by jim on October 22, 2012

In an important challenge to the way EPA has gone about regulating the tiniest and most harmful forms of soot, or "Particulate Matter" pollution, attorneys for environmental groups seem to making some headway in the courts. Currently, EPA is about to recommend new PM pollution rules that will reportedly lower the exposure standard for "PM […]

We can't tell you how many times a resident from DFW will go on a business trip or vacation to a less-polluted place and report an almost instant shedding of the ill effects of dirty air, only to have an almost equally fast re-acquaintance with those effects once they return. Could air pollution really make […]
