Salt produces specific ozone-depleting chemicals under certain atmospheric conditions
Is it true that salt produces specific ozone-depleting chemicals under certain atmospheric conditions?
Yes. Multiple studies demonstrate that sea salt aerosols act as major sources of reactive halogens like chlorine and bromine, which chemically deplete ozone under specific atmospheric conditions.
Verdict: SUPPORTED · 2 sources for, 0 against · Last checked
The claim states that salt (sea salt aerosols) produces specific ozone-depleting chemicals under certain atmospheric conditions. Papers [5] and [8] directly support this by showing that sea salt aerosols undergo chemical reactions (such as debromination and halogen activation) yielding reactive chlorine and bromine species that actively destroy ozone in the atmosphere. The evidence is solid and well-supported within atmospheric chemistry modeling.
