Reactive ozone gases
WebThe abundance of these gases is measured in amounts typically below a few parts per billion, down to parts per trillion, but the reactive radicals (ClO, BrO) can destroy ozone rapidly (at the rate of 1 percent/day in the lower stratosphere, during polar winter/spring) via catalytic reactions whereby one atom of chlorine (or bromine) can lead to ... Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth's upper atmosphere (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad … See more Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2).
