LA is known for its beautiful sunlight. Scientists call it pollution It’s Daylight Saving, that time of the year when we get more of that gorgeous L.A. light. To scientists, it’s a bit more complicated.

That ‘LA Glow’? Mostly dystopian. laist.com/news/los-ang...

On my way to the Royal Society of Chemistry for this year's #airpollution conference.

Really looking forward to hearing from today's great line up of speakers, including a session on AQEG's work.

Thanks @sellathechemist.mastodon.social.ap.brid.gy for inviting me (and thanks to my PhD supervisor David Rowley for the action shots). Till next time! 3/3

Also terrific to see 1st-year undergrads work with schools to measure NO2 across London using diffusion tubes for #UCLChemAirPoll. Truly impressed with the work of the students and coordinators @sellathechemist.mastodon.social.ap.brid.gy, @stephenepotts.bsky.social & Eleanor Gershenson-Smith 2/3

Great to be back at my old stomping ground at @uclchemistry.bsky.social to tell students about the work on diffusion tubes 🧪 for #airquality monitoring that myself and my team at @npldigital.bsky.social have been doing 🧵 1/3

Places are filling up fast for December's Air Quality in the 21st Century at the Royal Society of Chemistry.

It's a science adventure from the work of AQEG to net zero, health gains from air pollution actions, UFP, shipping, inequalities in exposure the ULEZ and more.

A person speaks on the microphone, surrounded by poster boards, and with a large digital screen behind. The screen displays a graph about atmospheric processes.

A large group of people sit and smile while looking ahead.

A large digital screen displays a variety of graphs. Behind the screen, a gorgeous stained-glass window establishes the church-like location. Rows of people sit facing the screen.

Two people talk while looking at some leaflets. There are other people and banners in the background.

Last week we hosted the first UK Atmospheric Chemistry Conference, with the @ukceh.bsky.social and @nceoscience.bsky.social.

It was great presenting my work and catching up with colleagues old and new at the 1st UK Atmospheric Chemistry conference in York. Looking forward to the next iterations in the future #atmoschem

Mitigation of Indoor Ozone and Secondary Products from 222 nm Germicidal Ultraviolet Light Using Commercial Air Cleaners Far ultraviolet-C (UVC) light, especially germicidal UV light at 222 nm (GUV222), has received considerable attention for its potential to deactivate airborne pathogens indoors and prevent the spread of infectious disease. However, GUV222 also generates ozone (O3), posing human health risks and initiating additional photochemistry that may degrade indoor air quality. Air cleaners present an opportunity to counteract the drawbacks of GUV222 by removing harmful byproducts; however, to our knowledge, this has never been demonstrated. Here, we conduct laboratory experiments in a 7.5 m3 Teflon chamber using two commercially available air cleaners─a manganese-oxide-catalyst “ozone cleaner” and an activated-carbon-HEPA “volatile organic compound (VOC) + particulate matter (PM) cleaner”─each simultaneously with a GUV222 lamp. We show that both cleaner types remove a wide range of key pollutants, including O3, NO2, formaldehyde, VOCs, and particles. Application of chamber results to a photochemical model simulating chemistry in a 150 m3 room suggests that a single cleaner can achieve modest reductions in O3 levels and substantial reductions in secondary pollutant levels within typical indoor environments. These results indicate that indoor air pollutants from GUV222 can be mitigated through the use of air cleaning technology, thereby improving indoor air quality while maximizing the potential benefit of germicidal UV for human health.

Forgot to post this — new(ish) air cleaner paper! In work led by Nadia Tahsini, we showed that catalyst- and charcoal-based air cleaners can lower levels of many indoor air pollutants, including those formed by germicidal UV lamps.

A person carries a large Pride flag. The sky is bright blue, and the person is surrounded by some greenery. On a yellow background, text says: ‘Science professionals who are lesbian, gay, transgender, bisexual, queer, intersex, and asexual (LGBTQ+) are more likely to experience career limitations, harassment, and professional devaluation than their peers. In scientific research, underrepresentation and discrimination of people from sexual and gender minorities casts a shadow over our future.’

In an indistinguishable crowd of people, a hand is raised in the air, holding a small Pride flag. The scenery is urban, with tall brown buildings all around. On a yellow background, text says: ‘People who are LGBTQ+ may also have intersectional identities – where they belong to more than one minority group or have more than one protected characteristic. They may be dealing with intersectional issues, such as transphobia and racism, ableism and sexism, and so on. There is no place in science, or outside of it, for prejudice. But there is plenty of space for recognition and support.’

On a yellow background, text says: ‘5 ways to support LGBTQ+ scientists: Diversify your social media feed. Your activity on social media can help foster a more inclusive research environment. / Actively seek out LGTBQ+ voices to help understand new concepts, perspectives and ideas. / Embrace inclusive language and gender pronouns. If you make a mistake, apologise, correct it, learn from it and move on. / Get involved with community events as an ally. / Recognise and champion diverse role models where you can.’

In scientific research, underrepresentation and discrimination of people from sexual and gender minorities raises significant concerns over equality, damages innovation, and threatens the wellbeing of staff.

Let’s recognise, empower and celebrate LGBTQ+ communities in science and beyond 🏳️‍🌈

When Green Turns Gray: How Heatwaves Turn Plants into Unexpected Polluters New UC Irvine research reveals how extreme heat events can make everyday greenery a hidden contributor to air pollution.

Check out the latest research from our group at UC Irvine. We show that some plants (e.g., sedges and cypresses) can significantly increase their volatile emissions during a heatwave and adversely impact air quality. #BVOC @huiwangisop.bsky.social ps.uci.edu/news/3258

Just spent today at this excellent meeting at the Royal Society of Chemistry. Given us all a lot to think about. I had planned on taking some pictures of the fancy buildings, but I was a bit too preoccupied with the science!
