The impact of volcanic emission of halogenated compounds on the Southern Hemisphere and Antarctic environment
Ukraïnsʹkij antarktičnij žurnal
The study aims to estimate and compare the global emission for 20 halocarbons from volcanic and hydrothermal sources into the Earth's atmosphere. It follows from the results that the contribution of volcanic emission for these species in the depletion of stratospheric ozone in the catalytic halogen cycles does not exceed 0.1%. Still, they significantly impair the level of tropospheric ozone near the volcanoes. The scheme of gas-phase free radical chain halogenation of the hydrocarbons isdoi:10.33275/1727-7485.2.2021.675 doaj:550e08ca3ab4435a91aa7a7b1a34c1c3 fatcat:aaooo242ojf2vhezmefintwade
