The thing about Valley smog, the ‘muck’ stops here

Oppressive is how San Joaquin Valley, California summertime heat can be. Temps of 104, 105, 106, 107 and higher aren’t uncommon. Heat as high as that becomes more than a bit uncomfortable and gets old rather fast the longer those triple-digit temperatures hang around. When that happens, talk about such in these here parts seems … Read more

Message to fellow Americans, earthlings: Stay the course on emissions-reduction, please!

This year, the American Lung Association in its 2017 “State of the Air” report was clear: four-in-10 Americans live in counties with unhealthy air. That’s not too, too bad considering six-in-10 don’t. When you think problematic air, there are a whole slew of so-called “hot spots.” The more familiar ones are such cities as Beijing, Delhi, … Read more

Air: taken for granted or until causing major personal upheaval, air appears to matter little

At 19, in 1972 in September, I got my first real taste of smog. You see, it was on a visit to Fullerton, California, that I really took note.

Finding common ground re PM 2.5’s effect on health, not that simple, it seems

Particulate-matter pollution, a multi-dimensional air contaminant, is of particular concern, especially a finer version of it or that known as PM 2.5 or fine particulate matter less than 2.5 micrometers in diameter (about 1/30th the width of a typical human hair). That PM 2.5 is present in the air is on account of the incomplete … Read more

For air-pollution conversion device, the sky’s the limit

Researchers in Belgium have created a device which can convert polluted air into energy. That’s just one of the device’s capabilities. The other is its ability to make air pollution harmless. The catch: light from the sun is needed to facilitate both processes. “‘We use a small device with two rooms separated by a membrane’, … Read more
