🚦During summer 2020, London’s lockdown cut traffic exhaust by almost half and 🍳 cooking emissions by 2/3 compared to summer 2019. But when Eat Out to Help Out launched, cooking-related pollution doubled. @imperialmed.bsky.social @imperialsph.bsky.social @granthamicl.bsky.social @theguardian.com

Understanding what’s in the air we breathe is the first step toward reducing exposure and improving health outcomes.
Check out the new tool, PM dashboard 🖥️we upgraded over this summer here 👉 aerosolscienceerg.shinyapps.io/Landing_Page/

Tutorial Video for Dashboard | ERG Aerosol Science
We believe air pollution information should be accessible to everyone. That is why we’ve made some major improvements to our dashboard since 2023. 📍More sites – Honor Oak Park, Marylebone Road and C...

Glad to be part of this study to demonstrate how high-time resolution measurements could help identify the most "health-relevant" components of PM in terms of their oxidative potentials. Congrats to Steve for his great work! More details at: doi.org/10.1016/j.en...
