How is pollution created?

what about particulate matter!!

Particulates need to be listed here!!! —Preceding unsigned comment added by 69.109.226.186 (talk) 06:52, 25 November 2007 (UTC)[reply]

"...induce health effects" Should this be "defects"?Calmcanuck 16:46, 18 December 2007 (UTC) —Preceding unsigned comment added by Calmcanuck (talk • contribs)

So who in EPA-OAR is way too on top of this page? This is such a heavy-handed attempt, even for Wikipedia.

OK, so I've added a subsection on particulates, but I think that much more should be said. My Gussie (talk) 17:07, 23 December 2016 (UTC)[reply]

I

I wouldn't call a non profit organization that gives out more information about iaq "spam" Valerielgreen (talk) 20:36, 17 October 2008 (UTC)[reply]

Wikipedia counts any external link that appears to have been added primarily to promote a website as "spam". It is perhaps a looser definition of the term than you're used to. There are dozens of similar organizations. We can't list them all (Wikipedia is NOT a web directory), so it's fairer not to list any of them.

Now if you had a link to a page with detailed information that is not already present in this article, and you were linking directly to that page, then we could talk about it. WhatamIdoing (talk) 01:03, 18 October 2008 (UTC)[reply]

Collaborative for High Performance Schools?

Under the heading "Institutional Programs," there is a reference made to the EPA's IAQ guidelines for educational facilities. The Collaborative for High Performance Schools (CHPS) is a non-profit organization that oversees a green rating program for K-12 schools. CHPS is referenced as a resource on the EPA's website. CHPS addresses indoor air quality, low-emitting materials, daylighting and a range of other design features for school buildings. Could CHPS be added to this section? --Zucchini22 (talk) 23:12, 28 October 2008 (UTC)[reply]

Indoor plants on air quality

There should be a section on Kamal Meattle and his research on commercial buildings and the effectiveness of 3 plant types on cleaning indoor air quality and producing enough oxygen for the inhabitants to survive with the building completely sealed off. — Preceding unsigned comment added by 105.233.24.166 (talk) 18:53, 17 August 2014 (UTC)[reply]

Carbon Dioxide

I think there may be an error in the sentence below:

The lower the air exchange rate, the slower the buildup of carbon dioxide to quasi "steady state" concentrations on which the NIOSH and UK guidance are based.

Shouldn't it read,

The higher the air exchange rate, the slower the buildup of carbon dioxide to quasi "steady state" concentrations on which the NIOSH and UK guidance are based.

Techguy95 (talk) 20:01, 4 May 2016 (UTC)[reply]

@Techguy95: first off, that entire paragraph is poorly written and unsourced, so you'd be within your rights to blank it. That said, I do not think your proposed change is correct. The (unwritten) assumption behind the sentence you quote is that spaces designed with low air change rates have lower occupant densities. So for example, once a high air change rate space such as an auditorium becomes occupied, its CO2 concentrations rise and level off very quickly compared to a low air change rate space such as a library.

Outdoor air CO2 concentration.

The paragraph in the “Common Pollutants” section dealing with CO2 says “Outdoor CO2 levels are usually 350–450 ppm.” Since the well-mixed global concentration measured at the Mauna Loa observatory is currently >400 ppm, would that not be the minimum concentration to be found outside buildings in populated areas?

DogFoxen (talk) 04:25, 5 February 2020 (UTC)[reply]

This is entirely an educated guess, but local outdoor air CO2 concentrations will be affected by both local sources and local sinks of CO2. For example, a building sited near a forest could experience lower outdoor CO2 than the global average measured at Mauna Loa. A recent ASHRAE Technical FAQ^[1] cites typical outdoor CO2 ranges from 300 to 500 ppm. Perhaps it is better to revise the numbers in accordance with this source since the current numbers appear unsourced. Karma Heretic (talk) 16:15, 13 February 2020 (UTC)[reply]

confusing sentences

I am listing sentences that are grammatically confusing to me.

"These afflictions often cannot be attributed to a single cause, and require a comprehensive analysis besides the testing of the air quality. Factors such as the workplace design, lighting, noise, thermal environment, electromagnetic fields, ionising radiation and psychological and mental aspects have as well to be allowed for."

Please update with: "Chemistry and human exposure implications of secondary organic aerosol production from indoor terpene ozonolysis"

I think it would be good to add brief info about results from this study to the article somewhere. Maybe it's also relevant at another article. It's featured in 2022 in science (February) and included in (the new section) Monoterpene#Health effects like so:

A study suggests that a range of floor cleaners with certain monoterpenes may cause indoor air pollution equivalent or exceeding the harm to respiratory tracts when the time is spent near a busy road. This is due to ozonolysis of monoterpenes like Limonene leading to the production of atmospheric SOA.^[2]^[3] Another study suggests monoterpenes substantially affect ambient organic aerosol with uncertainties regarding environmental impacts.^[4]
