    “…The results presented here challenge the current view of the half-lives of pesticides in the lower boundary layer of the atmosphere and their impact on air quality and human health. We demonstrate that semivolatile pesticides which are mostly adsorbed on atmospheric aerosol particles are very persistent with respect to the highly reactive hydroxyl radicals (OH) that is the self-cleaning agent of the atmosphere. …”

    “…Here we show that gas phase DMS concentrations (DMS(gas)) increased by an order of magnitude when three Indo-Pacific corals were exposed to air in laboratory experiments. Upon re-submersion, an additional rapid rise in DMS(gas) was observed, reflecting increased production by the coral and/or dissolution of DMS-rich mucus formed by the coral during air exposure. …”
