When #JohnsHopkins scientists drove their air testing van to #CancerAlley they didn’t have a lot of pre-existing studies to compare to. And the #petrochemicalindustry self-reports to the EPA. What they found astonished them. What does it mean for the people there? Go to bit.ly/3STi1AP to learn more.

Here's a little preview of what we've been working on here at @johnshopkinsehe.bsky.social

A belated earth day to all! Sharing a channel of short videos discussing the importance of environmental health research and keeping the planet and ourselves healthy: www.youtube.com/playlist?lis...

Our in country partners at ICIMOD were instrumental in the success of this project, and communicated these results to local officials.

We collectively learned so much from this work, trained the next generation of scientists, and advanced our understanding of air quality. ❤️ NSF funding for this!

Ben Werden from my group included additional air quality assessment papers for the KTM valley using AMS source apportionment and comparing with the filter based source apportionment (finding generally good agreement).

and
pubs.acs.org/doi/10.1021/...

Islam et al. from the Stone Group had a series of papers on Ambient Air Quality from different areas KTM valley and Lumbini and in different seasons:
acp.copernicus.org/articles/20/...
pubs.acs.org/doi/10.1021/...
and pubs.acs.org/doi/10.1021/...

Doug Goetz from my group used a mini-Aerosol Mass Spectrometer to look at emission factors, size resolved composition, and mass spectral (chemical fingerprints) of these particulate sources:
Goetz et al. acp.copernicus.org/articles/18/...
and
pubs.acs.org/doi/10.1021/...

We started by characterizing south asian sources of air pollution: Stockwell et al. acp.copernicus.org/articles/16/... looked at trace gases and light-absorbing carbon.
Jayarathne et al. acp.copernicus.org/articles/18/... used filter based measurements to focus on particulate matter

10 years ago, my group went to Kathmandu in to participate in the NAMaSTE project (NSF sponsored) to measure sources and ambient air quality. An earthquake, stranded instruments, and recovery delayed our work, but we stuck with it and the whole team produced impactful work.

The @washingtonpost.com covered our new cumulative risk paper: www.washingtonpost.com/climate-envi...

Great story by Amudalat Ajasa.

Wait, do I have to start using Bluesky now?

New paper: super excited about working with risk scientists to systematically address how all the stuff we breathe (at least what we can measure) adds up to different health risks.

How nice to see @petedecarlo.bsky.social in my inbox! www.nytimes.com/2024/06/21/c...
