Secondary Organic Aerosols alive and well in fossil-fuel-combusted engine exhaust

In the Nov. 15, 2012 Pacific Northwest National Laboratory’s “Airborne particles smuggle pollutants to far reaches of globe” news release, Mary Beckman wrote: “Floating in the air and invisible to the eye, airborne particles known as secondary organic aerosols live and die. Born from carbon-based molecules given off by trees, vegetation, and fossil fuel burning, … Read more

Cleaning the air will require more than just paying lip service

I once saw a documentary called either “Super Trains” or “Supertrains” where I believe it was explained that one way of increasing the power output of a steam locomotive was, dimension-wise, to neither go broader in breadth nor higher in height (due to horizontal width and vertical height clearance limitations in effect at the time in the railway operating environment), … Read more

Is your furniture making you sick?

If I hadn’t read it with my own two eyes I never would have guessed that what’s in some furniture can potentially make people sick. The more I read, the more my interest was piqued. I, in fact, was quite taken aback once learning chemicals like chlorinated Tris, one of the more common, was removed from children’s pajamas … Read more

Word on ‘the street’: California’s ‘clear-the-air’ campaign appears to be working so far

The California Environmental Protection Agency Air Resources Board (ARB) states: “CA’s population reached 24 million people. Total registered vehicles surpassed 17 million and vehicle miles traveled is 155 billion. Cumulative CA vehicle emissions for [nitrogen oxides] and [hydrocarbons] remain at 1970 levels of 1.6 million tons/year despite a rise of 45 billion in VMT over … Read more

Court upholds California big rig and bus rule: Cleaner air forthcoming

The Public Policy Institute of California in its report: “Planning for a Better Future: California 2025: 2010 Update (Transportation),” revealed based on California Environmental Protection Agency Air Resources Board data, in California in 1975, and within the transportation sector, smog-forming emissions generated via passenger vehicles accounted for a full 70 percent with the remainder being released from heavy duty … Read more

eMission control – Focus: Seaways

Based on my reading of “California ships required to use cleaner fuel benefits public health,” written by Melissa Lin Perrella with the Natural Resources Defense Council (NRDC), it is my understanding a federal district court on Nov. 16, 2012 agreed to reject a lawsuit having to do with the Pacific Merchant Shipping Association’s (PMSA) challenge of a California regulation that requires … Read more

Plagued by polluted air: Is the San Joaquin Valley at increased asthma risk?

First things first. Keep in mind that from now until the middle of February the National Aeronautics and Space Administration (NASA) is conducting aerial air pollution reconnaissance in the skies over the San Joaquin Valley, a purpose of which is “… to help scientists better understand how to observe ground-level pollution from space,” according to NASA. … 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
