Ozone in the stratosphere can move downward to the troposphere, contributing to the "background" level of ground-level ozone. However, high levels of ozone in the troposphere are due to photochemical reactions involving volatile organic compounds (VOCs) and oxides of nitrogen (NO x: NO, and NO 2).Anthropogenic emissions (e.g., …

Top 3 effects of ozone layer depletion. Ozone layer depletion adversely affects humans, wildlife, marine ecosystems, plants, insects, and agriculture. When the ozone layer is thinned, more harmful UV-B radiation arrives to the Earth's surface.
Details
Health and Environmental Effects of Ozone Layer Depletion. There are three types of UV light: UVA, UVB, and UVC. Reductions in stratospheric ozone levels will lead to higher levels of UVB reaching the Earth's surface. The sun's output of UVB does not change; rather, less ozone means less protection, and hence more UVB reaches the Earth.
Details
Ozone is a gas composed of three atoms of oxygen. Ozone occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful …
