Debate continues on #aerosol composition affecting marine ☁️ formation.
While DMS was initially considered (since 90s) the main precursor, focus shifted to organics (early 00s). New analytical techniques now suggests methanethiol as another key sulfur precursor www.science.org/doi/10.1126/...
Marine emissions of methanethiol increase aerosol cooling in the Southern Ocean
Methanethiol is a significant contributor to global ocean sulfur emissions and to sulfate aerosol cooling over the Southern Ocean.

🌿🦠 Could air pollution increase the risk of long COVID?

A new study from Catalonia suggests exposure to PM2.5 and PM10 is linked to a higher risk of persistent #LongCOVID symptoms, including fatigue and cognitive dysfunction.

Excited to share the first real-time atmospheric measurements of #PFAS! We measured using acetate-CIMS in Toronto and see no evidence for direct emission of PFCAs. Rather, we see most are atmospherically formed. PFCA precursors must be considered and reduced! pubs.acs.org/doi/10.1021/...
High Time Resolution Ambient Observations of Gas-Phase Perfluoroalkyl Carboxylic Acids: Implications for Atmospheric Sources
Atmospheric formation of persistent perfluoroalkyl carboxylic acids (PFCAs) is a route to global contamination, including drinking water sources. We present high time resolution measurements of C2–C6 PFCAs in ambient air made over 6 weeks each in winter and summer 2022 in Toronto, Canada. Observations were made using chemical ionization mass spectrometry with acetate ionization, with care taken to avoid system contamination. Measurements of trifluoroacetic acid (C2 PFCA) are reported at 1 min time resolution, while those for C3–C6 PFCAs are at 10 min time resolution. Variations with time and relationships to meteorology and other pollutants show evidence of secondary formation of all observed PFCAs except perfluoropropionic acid (C3 PFCA). High time resolution data allow these unique observations, allowing for improved process and source understanding moving forward. Mixing ratios of TFA were larger than predicted from models that describe TFA formation from known precursors, indicating additional atmospheric sources of this molecule have yet to be identified.

I went pretty much with the that same list, and checking followers of people I know. I think I'll need to repeat the process a few times as more people are migrating over.

Tiesitkö, että #pienhiukkaset vaikuttavat pilviin? Tampereella on käynnissä tulipalo. Savuhiukkaset toimivat pilvipisaroiden tiivistymisytiminä. Koska ytimiä on enemmän savun vaikutusalueella, muodostuu enemmän pilvipisaroita ja ne ovat pienempiä. Satelliittikuva 6.11. MODIS/Terra.

Penguin guano and #aerosol production at the #oceanatmosphere interface .... a serious and interesting subject (at least interesting to me!) but I found that cartoon the cutest ...
