CATS: To recycle e-waste sustainably or not – that is the question

Number five in the Clean Air Technologies Series. Besides air quality, my posts all have one thing in common: they were created using a computer. I don’t know about the rest of the world’s computer purchasers, but I know in my own history I have owned five total. Then I thought about ancillary devices like hard drives, … Read more

CARS: Contaminated-Air-Remediation Strategies

There are all kinds of ways to make air cleaner – everything from the simple to the substantial and from the subliminal to the sensational. From an earlier post – “Air pollution: The enormity of it all,” I listed various pollution sources. Repeating those here, these are: Agricultural Commercial (Business) Construction (and Demolition) Energy Production … Read more

EPA’s new fine particle standard fuels debate

Since the U.S. Environmental Protection Agency on Dec. 14, 2012 announced the health standard for fine particles (PM 2.5) and soot had been tightened from the previous standard of 15 micrograms per cubic meter of air set 15 years ago to 12 micrograms per cubic meter, this has prompted both discussion and debate. Sentiment is … Read more

Updated U.S. EPA-issued PM 2.5 standard will help in protecting public health

A new national standard for fine particle pollution (PM 2.5 or particulate matter pollution 2.5 micrometers in diameter) was issued by the U.S. Environmental Protection Agency (EPA) on Dec. 14, 2012, set at 12 micrograms per cubic meter of air. This replaces the previous standard of 15 micrograms per cubic meter, established in 1997. By year 2020 projections are 99 … Read more

Want a smaller carbon footprint? Think ‘inside’ the box

A little more than a month into this air quality discussion and noticeably lacking has been power generation. In this regard, change starts today. And what better place is there to begin than in my own home? I can think of none. It is helpful to understand the geography and meteorology of California’s San Joaquin Valley; the place I … Read more

A polluted air/warming world connection? On this the jury is still out, apparently

There appears to be growing belief, at least among Americans, climate disruption is real. And of Americans who believe, a majority, it seems, feel such is caused by human activity. In “Global Warming Poll: Climate Change A ‘Serious Problem’ To 68% Of Americans,” Huffington Post correspondent Alana Horowitz writes, “Of the 1,000 likely voters surveyed, 68 … Read more

On beating back emissions, if not now, when?

On Dec. 9, 2012, I posted: “To meet prescribed emissions-reduction targets, San Diego must get transportation plan right.” As I see it, 18 California regions in all including San Diego, are mandated by law to get this right in that each must step up to the plate greenhouse-gas-emissions-reduction-act-wise, particularly as it has to do with human-health impact. Moreover, in my view, … Read more

CATS: Wind turbines – An up-close-and-personal look

Number three in the Clean Air Technologies Series. Looking like giant fans and looming larger than life, nationwide, some 36,000 of these imposing structures stand tall. That’s the equivalent of an average 720 per state. Any way you look at it, that’s a whole lot of spinning going on. Now think for a moment if there weren’t … Read more
