Talk:Acid rain/Draft

Reviewing and revising this article

This article was created in January 2007 by a Citizen who has not been active since October 2007 (3 years ago). Since then, very little substantive work has been done on the article. The primary source for this article was Acid Rain as it existed in 2007, an online article which has been revised a number of times since then.

As of a few days ago, this article was almost completely a word-for-word copy of its primary source, and I started to review it and add references, wiki links, expand and/or delete parts as warranted for two reasons: (1) to make the article less of a word-for-word copy of an exiting online article and (2) to expand or revise the article as warranted. To that end, I have already made numerous small changes, added a completely new section, and added a graphic. I plan to continue my review and edits as time permits.

I have finished my edits to modify the article by formatting changes, some wording revisions/deletions/additions, addition of 3 graphics, creating a references section and creating some new references. I believe it is now a status 1 article and will change the metadata template to that effect.

Any comments by anyone? Milton Beychok 22:21, 2 November 2010 (UTC)

Milton, you did a terrific job with this article. No question article length appropriate to the need to cover the important aspects of the subject. Your graphic, very helpful.

A few comments and questions:

• You discuss comparisons of pH values, commenting on the 'importance' of small differences that might seem confusing to the reader not familiar with the logarithmic nature of the pH scale. Perhaps it would help to include a small table comparing pH values with hydrogen ion concentrations, over the ranges of pH discussed in the article.
• How does the decline of red spruce negatively impact specifically?
• Which contributes more to U.S. production of acid rain, coal or petroleum combustion?
• How much U.S. acid rain derives from fuel combustion by other countries?

Again, a masterfully prepared, readable, interestingly informative article. Anthony.Sebastian 16:22, 8 November 2010 (UTC)

Thanks, Anthony for your comments. I will add add a pH table such as you suggest. (probably a few days from now as I am tied up next day or two). Coal has more sulfur than most petroleum products and hence will form more sulfur dioxide which is an acid rain precursor. The loss of any trees on a large-scale is per se negative just the same as forest fires are negative. Perhaps I can find a photo of a forest devastated by acid rain. I have no idea how much of the U.S. rain is from fuel combustion in Canada ... but I think it more likely that we contribute to their acid rain more than they contribute to ours.
