Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.

Study finds marine workboat engines staying in service two times longer than estimated by EPA; emissions reduction implications

Green Car Congress

The US Army Corps of Engineers estimates that, as of 2014, there were approximately 9,000 Category 1 and 2 marine vessels operating on US waters. Since real-world workboat engines are operating with longer lifespans, the actual nitrogen oxide emission reductions are 52 percent weaker than predicted in EPA’s 2008 Rule calculations.
