Article Synopsis
- Ethylene oxide (EtO) is a volatile organic compound and carcinogen, with limited reliable data on its ambient concentrations near production facilities, raising exposure concerns.
- In February 2023, sensitive mobile measurements in southeastern Louisiana showed that 75% of sampled areas had EtO levels above the threshold associated with a 1-in-a-million cancer risk, with some locations exceeding levels indicating a 1-in-1,000 risk.
- This study revealed higher EtO concentrations than previous EPA estimates and highlights the need for improved monitoring methods to assess exposure risks in industrial areas.
The Southern Ocean plays an important role in determining atmospheric carbon dioxide (CO), yet estimates of air-sea CO flux for the region diverge widely. In this study, we constrained Southern Ocean air-sea CO exchange by relating fluxes to horizontal and vertical CO gradients in atmospheric transport models and applying atmospheric observations of these gradients to estimate fluxes. Aircraft-based measurements of the vertical atmospheric CO gradient provide robust flux constraints.
