Assessing reactive oxygen and nitrogen species in atmospheric and aquatic environments: Analytical challenges and opportunities

Reactive oxygen and nitrogen species (ROS RNS) play a crucial role in biotic abiotic processes. In the atmosphere, ROS/RNS are usually associated with air pollution. The ability of certain particulate matter constituents to influence formation cycling at atmosphere-biosphere-hydrosphere interfaces is important for observed linkages between atmospheric aerosols adverse health climate effects. Atmosphere-hydrosphere exchange fluxes affect chemical composition atmosphere surface waters compartments, acting both as source sink ROS/RNS. Therefore, detecting measuring this interface utmost importance. This article presents critical review on analytical challenges limitations existing methodologies measure particles waters. It also addresses suitability novel based carbon nanoparticles potential tools detection aquatic compartments. • Progress most prominent offline online analysis.
