#Particulate Matter (PM) from Showers

After I wrote about #PM from #ultrasonic #humidifiers, people asked how much PM does a hot #shower produce? TLDR: Much less for a quick shower, around 12 ug/m^3 compared to 800 ug/m^3 for the ultrasonic but it is probably mostly false positive readings from water condensation.🧵 1/

Revealed: almost everyone in #Europe is #breathing #ToxicAir. Guardian investigation finds 98% of Europeans breathing highly damaging #pollutedair linked to 400,000 deaths a year. #FossilFuels #PublicHealth #crisis fine #particulate #pollution #traffic #industry #domesticheating #agriculture https://www.theguardian.com/environment/2023/sep/20/revealed-almost-everyone-in-europe-breathing-toxic-air

Incredibly Niche: I made a tray and rack for the Ambient Weather wireless outdoor particulate air quality monitor (www.thingiverse.com)

I know this is incredibly niche but if you need it, you kinda really need it. xD...

The world is burning. At this point, should not be an abstract concept anywhere, anymore. 🙁 Time to act to mitigate/reduce global warming/climate change = now... Really, it was several decades ago. 😡

Photo: Morning haze shrouds the sun, not long after sunrise. The haze is a combination of smoke from out-of-control fires in Canada, hundreds of miles away, and moist morning air.
Chart showing fires have already consumed more than 3.5 million hectares of forest in Canada by early June, which is more than was consumed over the entire summers of 2016, 2017, 2018, 2019, 2020 and 2022. It took until August of 2021 for the same amount of forest to burn as has already burned this year.

"European Union countries and lawmakers will negotiate "Euro 7" proposals this year on tighter limits for car #emissions - for #diesel #cars, but not petrol - and for heavy-duty #trucks and buses, including nitrogen oxide and #carbon monoxide.

The rules would also cover tyre and brake emissions."

This will mean less air pollution and less #microplastics pollution. Car makers balk, but this is still better for them than a big push for public transit.
