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.

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!

[Delphine Farmer @ChemDelphine]

Excited that our overview paper on the CASA (Chemical Assessment of Surfaces and Air) study is out!

A fantastic collaboration with many groups to think about links between buildings, outdoor air, smoke, surfaces, and #indoorchem @marinavance

[Delphine Farmer @ChemDelphine]

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…

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….

[Delphine Farmer @ChemDelphine]

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!

[Jennifer Murphy @envchemjen]

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!

[Rachele Ossola @RacheleOssola]

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

@Embarnesey @ColoradoStateU @csu_chemistry @tofwerk @mzCHEMj I was mulling Chemical Observations of Rotting and Putrid Scent Emissions, but am concerned that (1) I will never get another grad student in my group ever, and (2) that we might actually have to compare to other rotting and putrid smells, and I’m not sure I’m up for that…

[Delphine Farmer @ChemDelphine]

The @ColoradoStateU corpse flower started blooming, so let the @csu_chemistry VOC sampling commence! @tofwerk brought a VOCUS up, and Rose Rossell and @mzCHEMj have cartridge sampling going…

[Delphine Farmer @ChemDelphine]

@RacheleOssola For more details on what exactly Rachele did https://t.co/GWsFR6nbkX

[Rachele Ossola @RacheleOssola]

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

[Delphine Farmer @ChemDelphine]

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!

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…

[Delphine Farmer @ChemDelphine]

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… https://t.co/La2x616shr

[Delphine Farmer @ChemDelphine]

@mzCHEMj Thanks to @DB_Millet and @mvermeuel for providing a PTR, Tyson Berg for analyzing CIMS data, and the very patient @mzCHEMj who was game to change her experimental design when regional wildfires impacted the air…

[Delphine Farmer @ChemDelphine]

@EmmersonKathryn @NicCarslaw @jacquirickard Yes - we did it at HOMEChem - see papers from Arata on the VOC emissions!
