This is a really interesting analysis measuring inequalities in exposure to PM2.5 in children living in London and the surrounding area. Exposure to PM2.5 is measured over a 24 hour period, including both outdoor and indoor exposure. The indoor exposure to PM2.5 is obviously more difficult to capture, and the authors report this as a novel feature of their work.
Their dataset contained 1.3 million children aged 4-16 and they were able to leverage several other databases to show more than half of these children have a higher than recommended exposure to PM2.5, that many of these children spend a great deal of time in their residences, and that this residential exposure is a significant contributor to their overall exposure. Interestingly, the analysis also reports exposure among different levels of socioeconomic status (using income quintiles) and, maybe unsurprisingly, finds higher exposure to PM2.5 in lower income households.
Five things to know about climate change and health going into COP 28
This article from the Yale School of Public Health isn’t new research but provides a good background about the importance of COP28 (Conference of the Parties) and what the conference entails. The article also provides five key findings from the Lancet Countdown on health and climate change report as suggested by Jodi Sherman and Robert Dubrow (if you’re not familiar with these authors, I would highly suggest you follow their work).
