Occurrence of parabens in aquatic environments and sediments and efficiency of wastewater treatment plants in parabens removal - Scientific Reports

Parabens are endocrine-disrupting chemicals, and their entry into the human body via water sources has adverse effects on human health. In the present study, the occurrence of methylparaben, ethylparaben, propylparaben, and butylparaben in three domestic, hospital, and industrial wastewater treatment plants, and in river water and sediments, was investigated. The samples were concentrated via solid-phase extraction and analyzed by high-performance liquid chromatography. Results showed that the recovery percentage for all examined parabens was within the acceptable range of 97.4% to 103.6%, and the highest paraben concentrations were observed in influents from the hospital wastewater treatment plant (methylparaben: 34.4 ± 3.6 µg/L; propylparaben: 30.9 ± 5.4 µg/L). The study indicated that processes used in wastewater treatment plants are unable to completely remove parabens; however, the anaerobic-anoxic-aerobic process has the highest efficiency for paraben removal. The anaerobic-anoxic-aerobic process’s efficiency for removing methylparaben, ethylparaben, propylparaben, and butylparaben was 72.24%, 78.37%, 79.57%, and 72.99%, respectively. Based on the results, the anaerobic-anoxic-aerobic process can be used as a primary treatment to reduce the concentration of emerging contaminants in wastewater. Given the health effects of parabens, future studies should investigate processes capable of completely removing emerging pollutants such as parabens from aquatic environments.

Hidden gem: Angel of the Ruins is removal, a body, and a land early when seven mana is not happening. Plainscycling makes the clunky mode way easier to justify in white decks.

Commander skill check I still fail: knowing when to let a scary permanent live because someone else is the actual problem. Do you remove the first threat you see, or save answers for the player quietly setting up? #MTG #Commander #EDH #ThreatAssessment #Removal #TablePolitics

Reddit's harassment filter

This feature was enabled long ago for r/freebsd. Filtering was recently increased from moderate, to high.

Its first catch since the increase is pictured below. This case would probably have been caught by the moderate filter.

Moderators see the abuse, the red alert.

Normal users of the subreddit see nothing. Smart.

(It's possible that u/reddit_original saw the comment by u/ArtSuspicious7027 because the offending comment was a reply to u/reddit_original. I'm not certain.)

A Wayback machine capture of the offender's profile, after manual confirmation of the removal: <https://web.archive.org/web/20260519151033/https://old.reddit.com/user/ArtSuspicious7027>.

The abuse that's removed from a subreddit e.g. <https://old.reddit.com/r/freebsd/comments/n8ugn4/why_isnt_sudo_preinstalled/omobmk6/> remains visible in an offender's profile. This can help the public to form an opinion of the person, even if the person attempts to obscure their comment history.

The City of Pasadena approved an organization to hire 600 goats to eat vegetation on the steep slopes of the Arroyo Seco and reduce wildfire risk. The pilot project was 100 acres (about 50 hectares). The goats finished their work much faster than expected. See this article in PasadenaNow.
