Sugarcane burning releases toxic "black snow," fueling asthma, COPD, and cancer risks. This harvest method chokes low-income areas with formaldehyde and PAHs, damaging both health and our planet. We must end this toxic pollution for a cleaner future. #EarthDay

Detection of interstellar 1-cyanopyrene: A four-ring polycyclic aromatic hydrocarbon
Polycyclic aromatic hydrocarbons (PAHs) are organic molecules containing adjacent aromatic rings. Infrared emission bands show that PAHs are abundant in space, but only a few specific PAHs have been d...

Alright let’s talk about what’s actually in wildfire smoke.
Wildfire smoke is a complex aerosol containing fine particulate matter (PM2.5), carbon monoxide, nitrogen oxides, volatile organic compounds, aldehydes (including formaldehyde), benzene, and polycyclic aromatic hydrocarbons (PAHs)

Fox host Brian Kilmeade dismissed the advice of the network’s own senior medical analyst, Dr. Marc Siegle, by saying there is “not a chance” he will wear a KN95 mask.

You at the back! It's SHOO-IN. Not shoe-in because what the fuck is that supposed to mean? "Relax, you got the job, we just need to kick you through the FUCKING DOOR?" Shoo-in. FUCKING SHOO-IN. Like an old-time cinema usher, go on, you're all right, in you go. Kindly. Not shoe-related. Fuck's sake.

The barbecue scent is caused by carbon molecules called polycyclic aromatic hydrocarbons (PAHs), which are often caused on Earth by the incomplete combustion of organic matter, such as meat. It turns out PAHs also occur naturally in space and can commonly be found across the universe. (2/3)

PAHs are aromatic molecules consisting of multiple adjacent benzene rings. Gabi Wenzel et al. use #radioAstronomy to detect the 4-ring PAH cyanopyrene in the interstellar medium, and use its abundance to discuss the life-cycle of PAHs in space. 🧪🔭 #astrochemistry

At the same time, as our case revealed, the water companies have lobbied vigorously to prevent the sludge testing rules from being updated. So sewage sludge is simply not tested for the great majority of toxic contaminants, from PFASs to dioxins, furans, PAHs, microplastics etc.

one of my favorite things is when you can quickly identify other readers because everyone’s eyes start darting likewhen someone says “pōst-HUM-iss-lee” & you’re all simultaneously wondering “isn’t it ‘PAHS-tcha-muss-lee’? wait. shit. have i never said it? have i never heard someone say it out loud?”

Never make fun of someone if they mispronounce a word.
It means they learned it by reading.
