Athens crisis years smog

The Athes metropolitan area and some major Greek cities appear to have smog after 200 years again. The use of the cheaper wood instead of the heavy taxed heating oil is the major reason. Article needs extension. — Preceding unsigned comment added by Vagr7 (talk • contribs) 12:11, 9 January 2014 (UTC)

More intense sunsets

The article fails to mention the sole silver lining of smog: it enhances the intensity of colors during sunsets. Smoggier days in California lead to a greater variety and richness of colors as the sun goes down. We know that things that taste especially good are often unhealthy; so it appears that things that look good can be, too. 201.105.84.113 (talk) 22:02, 9 December 2014 (UTC)

Health effects

There appears to be an inconsistency with the Wikipedia article on Peroxyacyl Nitrates.

That article states that the health effects of Peroxyacyl Nitrate are more serious than Ozone. However, the Health effects section here does not mention the health effects of Peroxyacyl Nitrates even though they are correctly listed as one of the constituents of photochemical smog.

Plants as "causes" of smog

The idea that plants cause smog is misleading. This is a problem made famous by Ronald Reagan in 1980. Yes the hydrocarbons emitted by plants can contribute to eventual smog formation, but without NOx from another source (fire, severe lightning, combustion engines) smog doesn't form.

I would propose moving plants from the header "causes" to a different section (formation/reactions?) Anonrfjwhuikdzz (talk) 02:45, 18 February 2025 (UTC)

Watch out for blanking

Someone has just removed an external link to a major new PBS feature documentary about the history of smog (and the fight to remedy it) in Los Angeles--no good! Please be on the lookout for such blanking (apparently done by means of some sort of Wikipedia bot) in the future.

Your edit was removed because it did not meet the guidelines, please see WP:PROMO 🌊 oceanloop 03:59, 27 August 2025 (UTC)

And s/he has done it again. It appears that this editor only knows how to blank others' good-faith contributions without first engaging in "Discussion," rather than making solid, constructive edits. No good! And not collegial, as our founder has asked us to be.
