Environmental chemist. Professor. Very amateur wildlife photographer. I study the air we breathe (indoors and out) and how it impacts forests, health & climate.

¿Qué tanto apreciamos y cuidamos nuestro planeta? El Amazonas, además de ser el pulmón del mundo, es una gran fuente de biodiversidad y agua. Sin embargo, la deforestación y los incendios son una gran amenaza. ¿Podrá sobrevivir el Amazonas al cambio climático? #hilandociencia2024

So disappointed to learn that the cardboard box has a poster and not a baguette… #Paris2024

@ChemDelphine and I wrote a Conversation article about trees holding their breath during wildfire smoke. If you can smell the smoke, chances are trees feel it, too. https://t.co/BrFUNCvmFn via @ConversationUS
theconversation.com
An unplanned experiment when wildfire smoke rolled through Colorado shows how trees keep some of the smoke out.

Take a look at the paper for initial findings: humidity effects on SVOC levels, O3 interactions with infiltrated NOx to make N2O5, and even how a dishwashing machine impacts indoor chlorine chemistry!

We worked at NIST with @Poppendieck and team, groups from UNC @TurpinLab on water soluble chem, Berkeley @allenhgoldstein on semi volatiles, Toronto on gases including @jenna_ditto, UCSD and Michigan on surfaces @Rachel_E_OBrien, MIT on low cost sensors, OSU on microbes…

Excited that our overview paper on the CASA (Chemical Assessment of Surfaces and Air) study is out! https://t.co/thJUfpybTr A fantastic collaboration with many groups to think about links between buildings, outdoor air, smoke, surfaces, and #indoorchem @marinavance

The Chemical Assessment of Surfaces and Air (CASA) study aimed to understand how chemicals transform in the indoor environment using perturbations (e.g., cooking, cleaning) or additions of indoor and...

Not saying that @DB_Millet HAS to submit his 2001 abstract, but just saying that if he finds a floppy drive reader on eBay that he can….

And to be clear, you don’t have to be the one who collected the data to submit! Students who have been handed inscrutable old datasets - or comparing new data to old - strongly encouraged to submit!
Can old data teach us new things (or remind us of things we've forgotten)? Inspired during a visit back to Berkeley by @TimothyHBertram,@CappaSnappa proposed a session with editorial support from@ChemDelphine and me. Hope to see you and your vintage data at #AGU24!

Our protocol to collect water-soluble material from leaf surfaces is out in #ESPI @EnvSciRSC! A team effort with wonderful colleagues in @ChemDelphine's group – @mzCHEMj, Rose Rossell, and Cameron Osburn. Some non-technical science highlights below (1/n) https://t.co/53GXpJ45eB

@RacheleOssola For more details on what exactly Rachele did
Leaves occupy as much area as lands on Earth, are covered by chemicals, and are in permanent contact with atmospheric oxidants – yet their potential as reaction sites is underappreciated. Want to know more? Check out our last @ChemRxiv preprints below! ⬇️ @ChemDelphine @mzCHEMj

A new paper from @RacheleOssola is out! Rachele spent a lot of time thinking about the multiphase reactivity of leaf surfaces and how plant physiology, wet and dry deposition, and the phyllo sphere interact to control biosphere-atmosphere exchange! https://t.co/VMz1n8TzqD

Also, for a fun intersection of my research interests, there’s some cool partitioning and smoke VOCs in the story, and it turns out that the inner spaces of a leaf have some similarities to the indoor spaces of a house…

When wildfire smoke hits, how do plants respond? @mzCHEMj spent spent some time with pine trees and found out they are a bit like us: they close their doors, stop being productive, and despite their best efforts, still get exposed to smoke…

Glad to share our study of wildfire smoke and indoor surfaces in ES&T: https://t.co/jYXzzdtmvb We find that PAHs in smoke accumulate on indoor materials and persist for weeks at possible health-relevant levels. Good news - cleaning activities appear effective at removing PAHs.

Wildfire smoke contains PAHs that, after infiltrating indoors, accumulate on indoor materials through particle deposition and partitioning from air. We report the magnitude and persistence of select...
