Is there a reason for us to be concerned? Can ozone depletion really be connected to something that is truly harmful to humans? How much do we actually know about the ozone and the things that aregoing on in the atmosphere? There are many questions that come up when we talk about the ozone depletion in relation to skin cancer. In order to understand how the ozone affects us we must firstunderstand what the ozone is.
Ozone “is a gas that occurs both in the Earth's upper atmosphere and at ground level. Ozone can be "good" or "bad" for people's health and for the environment, depending onits location in the atmosphere” Towns and cities that have more traffic or more industrial plants have a higher potential for ozone formation, especially towns that also experience many warm sunny dayswith little wind. Since sunlight and heat are the engines that drive ozone formation, warm sunny days should have more ozone than cool or cloudy days. Wind can also play a role. On windy days the windcan disperse the ozone, causing levels to drop. Ozone pollution can be especially bad during summer heat waves when the air does not mix very well and air pollution doesn't disperse. How are wedirectly affected by ozone depletion?
How does Ozone Depletion affect skin cancer: The consequences of increased exposure of the human body to UV-B radiation will in the first illustration to be describedby the physical properties. “UV-B radiation does not penetrate far into the body; most of it is absorbed in the superficial tissue layers of 0.1 mm depth.” This restriction effects to the skin andthe eyes. However, a primary reaction in the superficial layers, have consequences throughout the body. The stratospheric ozone, which protects us from the sun, is excellent. There is also ozoneproduced near the ground, from sunlight interacting with atmospheric pollution in cities that are really bad. It causes breathing problems for some people, and usually occurs in the summer time when the...
