Lists of uncited chemicals

On 24 July, 79.12.242.18 added two long lists of chemicals in this series of edits. There are no citations for these chemicals. I propose to remove these lists.-- Toddy1 (talk) 15:59, 9 August 2018 (UTC)

You have my support. These chems are not only unsourced, the text is also poorly formatted (e.g. chemically) and poorly integrated into the article. Also, just listing a bunch of chems and classifying them without telling why they are classified the way they are is not very useful info to the reader. Keministi (talk) 19:45, 9 August 2018 (UTC)

Thanks. I have reverted the edits in question.-- Toddy1 (talk) 19:59, 9 August 2018 (UTC)

[ ===G-series=== Chemical form of the nerve agent tabun, the first ever synthesized. The G series of nerve agents. The G-series (Trilon) is thus named because German scientists first synthesized them. G series agents are known as non-persistent, while the V series are persistent. All of the compounds in this class were discovered and synthesized during or prior to World War II, led by Gerhard Schrader (later under the employment of IG Farben). This series is the first and oldest family of nerve agents. The first nerve agent ever synthesised was GA (tabun) in 1936. GB (sarin) was discovered next in 1939, followed by GD (soman) in 1944, and finally the more obscure GF (cyclosarin) in 1949. GB was the only G agent that was fielded by the US as a munition, in rockets, aerial bombs, and artillery shells.

Detection section

Someone tried to add a detection section that is almost exclusively about one method used to detect nerve agents. WP:UNDUE says that "Neutrality requires that each article or other page in the mainspace fairly represent all significant viewpoints that have been published by reliable sources..." Given that there are many methods of detecting nerve agents, having a section labelled detection that is just about one of them gives a distorted and inaccurate view of the topic. The section is shown below:-- Toddy1 (talk) 14:48, 5 September 2018 (UTC)

Detection section

=== Detection === Laser photoacoustic spectroscopy (LPAS) is a method that has been used to detect nerve agents in the air. In this method, laser light is absorbed by gaseous matter. This causes a heating/cooling cycle and changes in pressure. Sensitive microphones convey sound waves that result from the pressure changes. Scientists at the U.S. Army Research Laboratory engineered an LPAS system that can detect multiple trace amounts of toxic gases in one air sample. This technology contained three lasers modulated to different frequency, each producing a different sound wave tone. The different wavelengths of light were directed into a sensor referred to as the photoacoustic cell. Within the cell were the vapors of different nerve agents. The traces of each nerve agent had a signature effect on the “loudness” of the lasers’ sound wave tones. Some overlap of nerve agents’ effects did occur in the acoustic results. However, it was predicted that specificity would increase as additional lasers with unique wavelengths were added. Yet, too many lasers set to different wavelengths could result in overlap of absorption spectra. LPAS technology can identify gases in parts per billion (ppb) concentrations. The following nerve agents have been identified with this multiwavelength LPAS: dimethyl methyl phosphonate (DMMP) diethyl methyl phosphonate (DEMP) diisopropyl methyl phosphonate (DIMP) dimethylpolysiloxane (DIME), triethyl phosphate (TEP) tributyl phosphate (TBP) two volatile organic compounds (VOCs) acetone (ACE) isopropanol (ISO) Other gases and air contaminants identified with LPAS include: CO2 Benzene Formaldehyde Acetaldehyde Ammonia NOx SO2 Ethylene Glycol TATP TNT Other reported methods of detecting nerve agents are non-dispersive infrared (NDIR), traditional IR absorption and Fourier transform infrared (FTIR) spectroscopy.

Antidote to treatment

Can't see why anyone will have a problem with this but thought I'd play it safe. I renamed the "antidote" section to "treatment" - some of the drugs mentioneddo not act as antidote (ie "a remedy to counteract the effects of poison" MW) - atropine reduces the effect a nerve agent has on the body rather than counteracting the toxin. It also mentions two separate treatments, pralidoxime and atropine, noting that they may be administered together. Standard treatment for nerve agent poisoning is to administer both (eg army issue autoinjectors such as ATNAA and Mark I NAAK contain both of these drugs), to administer one on without the other is far less effective. Everything is cited so feel free to check it out. I also added Pyridostigmine bromide to the countermeasures in development section; it is preexisting so the section needed renamed, unsure of what is appropriate so just went with "Countermeasures". Alternatively can be split into two sections; maybe one on the development of nerve agent treatments as a whole. My knowledge of this stuff isn't huge so further additions may be beyond me! Comment if you have any issues/ideas! Editor/123 17:22, 27 July 2020 (UTC) — Preceding unsigned comment added by Ben8142 (talk • contribs)

Capitalization?

Are nerve agents capitalized? FinnSoThin (talk) 00:48, 4 July 2022 (UTC)

Should there be a section about the illegality of use?

https://www.reuters.com/world/what-are-chemicals-weapons-are-they-illegal-2022-04-12/

Chemical weapons production, use and stockpiling is banned under the 1997 Chemical Weapons Convention (CWC). Only Egypt, North Korea and South Sudan have not signed or ratified the international arms control treaty.
