Kinetics of Methylmercury Production Revisited

Laboratory measurements of the biologically mediated methylation of mercury (Hg) to the neurotoxin monomethylmercury (MMHg) often exhibit kinetics that are inconsistent with first-order kinetic...

Drought impacts on photosynthesis, isoprene emission and atmospheric formaldehyde in a mid-latitude forest

Isoprene plays a critical role in air quality and climate. Photosynthesis (gross primary productivity, GPP)and formaldehyde (HCHO) are both related to isoprene emission at large spatiotemporal scales...

Stable isotopic composition of perchlorate and nitrate accumulated in plants: Hydroponic experiments and field data

Natural perchlorate (ClO4−) in soil and groundwater exhibits a wide range in stable isotopic compositions (δ37Cl, δ18O, and Δ17O), indicating that ClO4− may be formed through more than one pathway...

Capabilities & Research Areas

Our multi-disciplinary team—which includes expertise in hydrology, geochemistry, microbiology, and biophysics—takes advantage of Oak Ridge National Laboratory's world-class experimental and computational facilities (i.e., neutron scattering, high performance computing resources, advanced imaging, and field-scale facilities and infrastructure) to generate foundational knowledge that aides policymakers in addressing pressing environmental challenges impacting air, water, and land resources globally.
