Floating chamber measurements

Researcher working with floating chambers

📣New paper📣
We measured #VOC & #CO2 fluxes from 3 ponds in a peatland forest using floating chambers. Understanding of freshwater ecosystems as VOC sources is poor, so this work led by Y. Qin, published in #ASLO_LO provides important new data.

When Green Turns Gray: How Heatwaves Turn Plants into Unexpected Polluters New UC Irvine research reveals how extreme heat events can make everyday greenery a hidden contributor to air pollution.

Check out the latest research from our group at UC Irvine. We show that some plants (e.g., sedges and cypresses) can significantly increase their volatile emissions during a heatwave and adversely impact air quality. #BVOC @huiwangisop.bsky.social ps.uci.edu/news/3258

Honored & grateful to @villumfonden.bsky.social for the grant, which will allow me to form a group exploring #peatland trace gas biogeochemistry. Many thanks to Profs. Rinnan, Kolb, Tang & Robroek for the support. Looking forward to the collaborations!

Prior to the #VOLTsymposium2025, we organize a
PhD course on VOCs and isotope techniques.

In addition to stable isotope techniques to study VOC production, consumption and emissions, you will learn data processing & generally about VOCs in ecosystem processes.

Awakening: Potential Release of Dormant Chemicals from Thawing Permafrost Soils under Climate Change Permafrost is a crucial part of the Earth’s cryosphere. These millennia-old frozen soils not only are significant carbon reservoirs but also store a variety of chemicals. Accelerated permafrost thaw due to global warming leads to profound consequences such as infrastructure damage, hydrological changes, and, notably, environmental concerns from the release of various chemicals. In this perspective, we metaphorically term long-preserved substances as “dormant chemicals” that experience an “awakening” during permafrost thaw. We begin by providing a comprehensive overview and categorization of these chemicals and their potential transformations, utilizing a combination of field observations, laboratory studies, and modeling approaches to assess their environmental impacts. Following this, we put forward several perspectives on how to enhance the scientific understanding of their ensuing environmental impacts in the context of climate change. Ultimately, we advocate for broader research engagement in permafrost exploration and emphasize the need for extensive environmental chemical studies. This will significantly enhance our understanding of the consequences of permafrost thaw and its broader impact on other ecosystems under rapid climate warming.

Check out our collaborative perspective in @EnvSciTech on "hibernating" chemicals in #permafrost and their potential awakening under #ClimateChange.
Congratulations to our postdoc Yi Jiao!

My review on volatile compounds in Arctic ecosystems was just published in Annual Reviews. It's a must-read if you're curious about why tundra plants smell strongly on sunny days & which gases besides CO2 and methane are released from thawing permafrost.

Heat waves may trigger unexpected surge in aerosol and ozone precursor emissions from sedges in urban landscapes | PNAS Biogenic isoprene emissions from herbaceous plants are generally lower than those from trees. However, our study finds widespread isoprene emission...

Dear colleagues, I would like to use my first Bluesky post to share our highlighted paper in PNAS about the discovery of a strong temperature response, with a Q10 over 7, for isoprene emissions from sedges and their role in affecting air quality during heat waves.
