The challenge is that most evidence (that I know of) uses average levels of pollution. I think there's an interesting question of whether having alternating heavy/light days causes similar impacts, or potentially worse/better

Yeah similar effect with melanoma, I learned recently, where burst exposures of sun (eg weekend warrior out on their bike) more risky than daily prolonged exposure (eg outdoor workers). We just don't have a precedent here

Interested to read recently ref PM exposure that it takes weeks to recover from a single exposure, so what happens when it happens repeatedly. Do we recover? Is the damage worse?

I’m sure
@CAR_CRE group would have some further info. Plus@christine_cowie, Geoff Morgan,@edjegasothy and others including Fay Johnston at UTAS. Some longitudinal work has started in Vic but still quite early days.1 reply 0 retweets 1 like -

This thread kinda suggests we have a gap in this area of research. Compared to tobacco control & smoking where we have 40+ yrs of evidence & data?

Very quick graph I threw together using AQI data from https://www.dpie.nsw.gov.au/air-quality/current-air-quality … and data from Prospect in Sydney. Orange line represents the avg AQI, red is at a "very poor" rating (where there start to be impacts for general public)pic.twitter.com/aIqSK4Qvju

Yep here's the same one for Albury. Similarly, red is at 150, but I've made the orange line at the median because there's a bit of a skew therepic.twitter.com/QNQxBFHD2J
