Policies to boost the economy can have unexpected environmental impacts. Traffic emissions are strictly regulated in Europe โœ…, 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

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 โค๏ธ๐Ÿซ.

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 ahead๐Ÿ”Ž

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...
