add regulatory efforts?[edit]

There is no discussion of regulatory efforts, such as EPA https://www.epa.gov/stationary-sources-air-pollution/dry-cleaning-facilities-national-perchloroethylene-air-emission Thanks.38.105.242.2 (

Interesting thread on the problems with drycleaners esp. in stripmalls, worth linking somehow?: https://twitter.com/realestatetrent/status/1437802803313922051 5.145.10.140 (talk) 17:14, 17 June 2022 (UTC)[reply]

Discovery[edit]

I have read both Victor Regnault's 1839 report and Faraday's 1820 discovery in his 1850s work and compared 2 compounds that both have discovered via thermal decomposition of hexachloroethane. Whatever Faraday synthesized in 1820,was carbon tetrachloride and not tetrachloroethylene as this article suggests. Faraday mentions that this compound of carbon and chloride did not react with chlorine and boiled at 160~170 degrees Fahrenheit (which are the properties of carbon tet). The other carbon chloride that V. Regnault synthesized in 1839 by the same process did not boil until 120 degrees Celsius. Faraday mentions that his chloride of carbon has a density of 1.55, carbon tetrachloride's density is 1.58 and tetrachloroethylene's is 1.62. Which one sounds closer? Victor Regnault's 1839 chloride of carbon reportedly has a vapour density of 5.83. Remember, he is commonly credited for carbon tetrachloride which has a vapour density of 5.3 and not tetrachloroethylene which has a vapour density of 5.7. 176.88.97.55 (talk) 15:39, 17 January 2023 (UTC)[reply]

... that tetrachloroethylene, the most common dry cleaning solvent, has been used as a medication against intestinal parasites in humans and animals?

Comment: It's my first nomination for a DYK. The article isn't new, I am adding more information its use as an anthelmintic. Previously I added info on this use to Turkish Wikipedia, I'm currently translating it for the English article.

This article has not been edited by a human for more than a month, therefore it is not eligible. Please read WP:DYKCRIT before nominating anything else.--Laun chba ller 19:27, 16 May 2024 (UTC)[reply]

I just added information about the use as an anthelmintic, with citations. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 19:30, 16 May 2024 (UTC)[reply]

To be considered here, articles need to be either completely new, expanded 5x by character count, or promoted to Good Article. None of these apply.--Laun chba ller 19:34, 16 May 2024 (UTC)[reply]

I thought one of the criteria was that the article should have been translated from another language, which is what I did with a section. I believe the information I gave is interesting enough to be featured as DYK. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 19:36, 16 May 2024 (UTC)[reply]

The rule is that transwikied content can count as new, but what you've added isn't enough; you've increased the total from 7147 to 8053. You'd need another 27682 characters to qualify.--Laun chba ller 19:44, 16 May 2024 (UTC)[reply]

Well, I plan on working on the article to make it a Good Article, would it qualify? ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 20:01, 16 May 2024 (UTC)[reply]

Highly cited review[edit]

By far the most cited review on tetrachloroethylene according to Chemical Abstracts: Grandjean, Philippe; Landrigan, Philip J. (2014). "Neurobehavioural effects of developmental toxicity". The Lancet Neurology. 13 (3): 330–338. doi:10.1016/s1474-4422(13)70278-3. PMC 4418502. PMID 24556010.

"A review. Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chems. that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chems. as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene. Since 2006, epidemiol. studies have documented six addnl. developmental neurotoxicants-manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated di-Ph ethers." Cited 1018 times.--Smokefoot (talk) 22:21, 16 May 2024 (UTC)[reply]

It doesn't feel "convincing" enough; you can't really know what effects would tetrachloroethylene have among many other chemicals on people (that's also why researches on dry cleaners are not convincing enough, too many other chemicals). If there are very strong neurotoxins like methylmercury compounds and toluene, you can't seperate their certain effects from tetrachloroethylene's possible effects. I feel like including this paper would make readers go "dry cleaning causes autism/ADHD/dyslexia". Researches involving multiple chemicals are flawed and shouldn't be cited for a suspected single chemical, in my opinion. ⲔⲖⲞⲢⲠⲒⲔⲢⲒⲚ (talk) 22:45, 16 May 2024 (UTC)[reply]

This paper reviews recent achievements and the current status of non-thermal plasma (NTP) technol. for the abatement of volatile organic compounds (VOCs). Many reactor configurations were developed to generate a NTP at atm. pressure. Therefore in this review article, the principles of generating NTPs are outlined. Further on, this paper is divided in two equally important parts: plasma-alone and plasma-catalytic systems. Combination of NTP with heterogeneous catalysis has attracted increased attention to overcome the weaknesses of plasma-alone systems. An overview is given of the present understanding of the mechanisms involved in plasma-catalytic processes. In both parts (plasma-alone systems and plasma-catalysis), literature on the abatement of VOCs is reviewed in close detail. Special attention is given to the influence of critical process parameters on the removal process."

Chlorinated solvents such as trichloroethene (TCE) and tetrachloroethene (PCE) are widespread groundwater contaminants often released as dense nonaqueous phase liquids (DNAPLs). These contaminants are difficult to remediate, particularly their source zones. This paper summarizes the progress made in improving DNAPL source zone remediation over the past decade, and is structured to highlight the important practical lessons learned for improving DNAPL source zone remediation. Experience has shown that complete restoration is rare, and alternative metrics such as mass discharge are often useful for assessing the performance of partial restoration efforts. Experience also has shown that different technologies are needed for different times and locations, and that deliberately combining technologies may improve overall remedy performance. Several injection-based technologies are capable of removing a large fraction of the total contaminant mass, and reducing groundwater concentrations and mass discharge by 1-2 orders of magnitude. Thermal treatment can remove even more mass, but even these technologies generally leave some contamination in place. Research on better delivery techniques and characterization technologies will likely improve treatment, but managers should anticipate that source treatment will leave some contamination in place that will require future management.
