For years, halogens have been known as destroyers of ‘good’ ozone, which acts as an upper-atmosphere shield from harmful ultraviolet radiation. Research now shows that natural halogen compounds emitted from the ocean help to control ‘bad’ ozone pollution at ground level and may continue to do so at a similar rate in future climate.

臭氧污染的自然控制

多年来，卤素素一直被认为是“好”臭氧的破坏者，它可以防止有害的紫外线辐射进入高空。现在的研究表明，从海洋中排放的天然卤素化合物有助于控制地面上的“恶劣”臭氧污染，并且在未来的气候中可能会以类似的速度继续下去。
