Specifically, we’ve made some major improvements to our dashboard since 2023.

📍More sites – Honor Oak Park, Marylebone Road and Chilbolton – to give a robust understanding of PM2.5 concentration patterns across the south-east of the UK.

Policies to boost the economy can have unexpected environmental impacts. Traffic emissions are strictly regulated in Europe ✅, but cooking emissions? Not yet. Hong Kong has rules and tech we can learn from. Read more here for an excellent piece written by @drgaryfuller.bsky.social @theguardian.com

How COVID-19 related policies reshaped organic aerosol source contributions in Central London Abstract. Organic aerosol (OA), a major component of submicron particulate matter (PM1), has significant impacts on both human health and climate. Quantifying its sources is therefore crucial for deve...

Our new study in Atmospheric Chemistry and Physics shows restaurants are a major source of tiny particles called PM, linked to heart and lung disease ❤️🫁. Solid fuel use in kitchens may have added to the spike. @egu.eu Read the full article: doi.org/10.5194/acp-... @imperialcollegeldn.bsky.social

🚦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

We had such a productive workshop with our long-lasting collaborators last week hosted by us @imperialsph.bsky.social @imperialcollegeldn.bsky.social
and supported by CNRS-Imperial connected fund. Really looking forward to exciting science ahead🔎

Get ready for our campaign at the roadside supersite in Central London to measure non-exhaust emissions.

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...
