Talk:Smog

Comments copied from talk page of my sandbox where the article draft was created

Revised lede to incorporate many of the suggestions by Anthony Sebastian.

Anthony, I had already considered using the word "portmanteau" to describe "smog" ( as was done in Wikipedia's smog article ) but decided it was too "fancy". Therefore, I chose to describe it as a "combination" word, which is simple and self-explanatory.

Other than that, I believe I have incorporated your suggestions in my re-write of the lede while still retaining the technical integrity of the wording. For example, it is not the polluted air that produces the precursors ... they are emitted into the air by vehicles and industrial activities. Thanks much, Milton Beychok 04:40, 22 August 2010 (UTC)

First comments

New York looks rather pretty in that picture. Designer smog?

Maybe the photographer used a color filter or maybe that is what it really looked like at that moment in time. Milton Beychok 22:21, 22 August 2010 (UTC)

Personal taste, but I hate "so-called"; it tends to imply doubt of the term. Certainly, there was a 1952 event in London.

Done. Milton Beychok 22:21, 22 August 2010 (UTC)

The first paragraph of "photochemical smog" doesn't seem to be about photochemical smog. Move it up to the previous section, and observe there's the original kind, but most now is photochemical, as a transition. Consider subheads in this section, perhaps "precursors" and "simplified reactions".

I think the first paragraph of "photochemical smog" is okay where it is ...but let me think about it a bit. Milton Beychok 22:21, 22 August 2010 (UTC)

Added the subheads for "precursors" and "simplified reactions", but a bit more wordy. Milton Beychok 22:25, 22 August 2010 (UTC)

Under "areas affected", make the headings consistent at country level. Haven't there been significant British incidents besides London? Birmingham vaguely comes to mind.

Country level headings done. There probably have been other significant British incidents. Perhaps others can add them after I upload the article into the article namespace. Milton Beychok 22:21, 22 August 2010 (UTC)

In the US, while LA is obviously the poster child, my informal impression is that Denver is worth mentioning, along with its particular topography. I'd be interested in hearing your opinion on their banning of wood-burning fireplaces. What about Pittsburgh before the industries cleaned up? Was that smog or some other air pollutant?

As for Denver and Pittsburgh, again perhaps others can add them after I upload the article into the article namespace. As for banning wood-burning fireplaces, I have no opinion. Milton Beychok 22:21, 22 August 2010 (UTC)

I have now added a subsection on Denver. Milton Beychok 02:15, 23 August 2010 (UTC)

As far as my birthplace of northern New Jersey, I'm not sure we called it smog, or necessarily air...just the burning tires, refinery waste, and Pig Farms of Secaucus, all fermenting over the Jersey Meadows. I remember holding my ground when someone, in a college lab, smashed a 5-pint bottle of butyric acid, and the professor said "you're from New Jersey, aren't you?" (turns out that it cleans up nicely with a slurry of activated charcoal in cupric sulfate solution).

Continental Europe

The first thing I noticed was that continental Europe is not mentioned. Are the air pollution problems of this region not classified as smog? I think that, at least, 30-t40 years ago there was indeed smog.

Now we have ozone warnings, and "Feinstaub" (fine dust?) warnings. --Peter Schmitt 08:43, 23 August 2010 (UTC)

Oh, not Europe, but certainly important: Beijing. --Peter Schmitt 09:24, 23 August 2010 (UTC)

Peter, the exclusion of Europe (other than London) was not intentional. Just did not run across any references that discussed smog in Europe. I will make an effort to find some. Thanks, Milton Beychok 15:45, 23 August 2010 (UTC)

Of course, you know that you need not contribute a complete article ...

As for Beijing: You may remember that they made special efforts to improve air condition during the 2008 Olympic games. --Peter Schmitt 23:38, 23 August 2010 (UTC)

Yes, Peter, I know that I need not write a complete article before uploading it into the article namespace ... but I like to make it as complete as I can, in a reasonable amount of time, before it leaves my sandbox. I have been doing that for over a year now. But thanks anyway. Milton Beychok 03:06, 24 August 2010 (UTC)

Some minor revisions and a suggestion

Hi Milt, I did a few edits directly and like the article as it is. The only thing I find not clear is the selection of the affected areas to be covered in detail — I think this would benefit from some sort of global ranking in terms of smog indicators. For the US, I found this list, and for the world, there are similar lists. --Daniel Mietchen 21:31, 25 August 2010 (UTC)

Daniel, thanks for your edits. The only one that I changed back to the original form was the TOC location which I feel results in a better overall appearance. Other than that, all of your revisions were fine.

As for the selection of the affected areaa, to be candid they were selected because I thought they were good examples of severe smog and also because I could find interesting material about those sections. Admittedly, more researching could disclose more to write about ... but the article struck me as large enough as is and I had already spent a couple of weeks on it, so I stopped researching. Milton Beychok 21:43, 25 August 2010 (UTC)

Comments after the article was loaded into article namespace

Wikipedia has an article of the same name

This article may contain some very few bits of content from the WP article. Milton Beychok 23:20, 25 August 2010 (UTC)

About recent edits by Daniel

Daniel,thanks much for your latest edits. I must have read through this article a thousand times ... and I still missed those. Milton Beychok 15:44, 26 August 2010 (UTC)

A few comments

Very nice so far.

Should it explictly say that smog can only be prevented; there is no way to break up a significant smog concentration once it is in place. Hayford may, however, remember the name of a science fiction story in which Earth prospered as the galactic equivalent of a fine wine district -- apparently, the rest of the galaxy considered bottled smog a wonderful delicacy. It was impossible to export enough. Howard C. Berkowitz 20:09, 1 September 2010 (UTC)

Policy and Laws generated to combat smog

could like to subpages / articles / sections that discuss

Legal Policy / Laws / gov't action to combat smog.

I just skimmed the article, so maybe this is already in there.

And then a timeline/figure and how we've improved the smog in LA from the 70s and 80s to now. Tom Kelly 18:31, 6 January 2011 (UTC)

Tom, I agree that a section about government actions or laws to mitigate smog would indeed be a good addition to this article. But it would have to be written by an environmental engineer with expertise and experience in dealing with those actions and laws ... in the United States as well as other countries. That would be a very difficult chore and not to be undertaken lightly by someone with no experience in that field. As of this moment, we really don't have any active members that have the needed expertise and experience. Milton Beychok 00:34, 7 January 2011 (UTC)

respectfully disagree on part. You do not need expertise to write a draft. That is what the wiki world is all about - anyone can contribute. If you want to get it approved, you probably need someone to do fact checking, etc. However, if you make it a subpage, I don't know if the subpage needs to get approved along with the main article. Or the draft could just be a 2nd article that is linked from this article. Tom Kelly 17:37, 28 January 2011 (UTC)

And I respectfully disagree with you, Tom. As one who spent about 20 years working in the environmental technology field and had to become acquainted with the multitude of environmental regulations in the United States (both national regulations and the various individual state regulations), I know how very difficult it would be to intelligently discuss those regulations ... as well as the regulations in England, France, Germany, Japan, etc., etc.,etc.

The idea that expertise is not needed and the wiki process will eventually evolve a good article is exactly what is wrong with Wikipedia. It does not always produce a good article. It does take detailed knowledge and direct experience to even draft an article about any technical subject ... and especially so when dealing with the worldwide aspects of environmental regulations.

Tom, you are a medical student. As such, would you trust anyone who has no medical expertise to draft a good article about the details of some intricate brain surgery? Milton Beychok 19:01, 28 January 2011 (UTC)

another great article idea related to this one

fine particle pollution - often around freeways from car exhaust

University of Southern California epidemiology research shows that children that live with a few hundred yards of freeways / highways have a much higher incidence of asthma.

fine particle pollution is going to be a very interesting topic to follow as smog was (and still is). Tom Kelly 17:40, 28 January 2011 (UTC)

Fine particle pollution is usually referred to as particulate matter pollution (or PM pollution) and the respirable fraction is denoted as PM_2.5, which is very small particulate matter having a size of 2.5 μm or less. Particulate matter pollution is discussed to some extent in the existing Acid rain, Air pollution emissions and Air Quality Index Citizendium articles as well as this Smog article.

Yes, an article on the epidemiology of PM pollution would be of interest. But it should be based on more than just one epidemiology research report.

Tom, just as trivial aside, it would be better if your post headers and proposed articles started with a capital letter (i.e., Another great article idea ... and Fine particle pollution). The same holds true for starting sentences (i.e., Fine particle pollution is going to be a very interesting ...). Milton Beychok 19:38, 28 January 2011 (UTC)

Yes, this would be a fine article idea especially since one of the greatest sources of PM pollution is from the Owens Valley, CA. Long ago I was told by a forest ranger the majority (he gave me a percentage but I can't remember the exact percentage but it was around 90%) of worldwide particulate matter pollution arises from the Owens Valley. Another source says the Owens Valley is the largest contributor for PM 10 see: [ http://www.epa.gov/region9/air/owens/qa.html] The Owens Valley was once a thriving community with steam boats carrying charcoal from the kilns until the water was removed by the Los Angeles Department of Water and Power with the assistance of the US federal government. This was done in the early 1900s. Today, when the wind blows particulate matter is scattered across the desert making life miserable for all concerned. And no I am not am not an environmentalist but I am a historian. See: [ http://www.usc.edu/libraries/archives/la/scandals/owens.html] or [ http://www.epa.gov/oaqps001/greenbk/pnca.html] or [1] Mary Ash 21:24, 28 January 2011 (UTC)

Mary, that EPA source labels the Owens Valley as the "largest single source" of PM₁₀ in the U.S. That does not mean it is the largest part of the total PM₁₀ in the U.S. and your forest ranger was hallucinating if he thought that the Owens Valley contributed 90% of the worldwide PM₁₀.

As an analogy, If one says that a particular industrial plant emits more air pollution than any other industrial plant in the U.S., it does not mean that it contributes most of the total air pollution in the U.S. Thus, if a certain geographical area (the Owens Valley) produces more PM₁₀ than any other geographical area in the U.S., it does not mean that it contributes most of the total PM₁₀ in the United States ... or of the total worldwide PM₁₀. Milton Beychok 22:58, 28 January 2011 (UTC)

Maybe she's confused with Buck Owens of Bakersfield, he sure polluted the airways for many years! Hayford Peirce 23:04, 28 January 2011 (UTC)

"9. How bad is the PM-10 problem in the Owens Valley? What are the PM-10 levels in Owens Valley? Owens Lake emits about 300,000 tons of PM-10 per year: 30 tons of this is arsenic and 9 tons is cadmium. Owens Lake is the largest single source of PM-10 pollution in the United States. It has caused on average about 19 violations of the standard every year at Keeler during the 18 years that the Great Basin Unified Air Pollution Control District has been measuring particulate matter. It is not a natural source, and the wind speeds (20 to 40 mph) that cause the dust events are not unusually high." I offered comments made over 20 years ago by the forest ranger and I suspect he knew what he was talking about. I also offered another source from the EPA. And no I am not confused as I've been following this subject since my college days thanks to Dr. Gerald Stanley who opened my eyes with his lecture called the Rape of Owens Valley. Yes, PM 10 matter is a serious subject worth writing about as I was writing about this topic for over two years as a journalist.Mary Ash 23:44, 28 January 2011 (UTC)

((unindent)) I was not wrong about the forest ranger either as he said it was either 85 to 90 percent. Once again are you implying that I am less than truthful? And why would I lie about something so trivial. The air pollution is not trivial and neither is destroying the environment causing many to suffer.Mary Ash 01:03, 29 January 2011 (UTC)
