Ground Level Ozone Linked to Cardiovascular Disease
The ozone is a protective layer in the upper atmosphere, which helps absorb UltraViolet-B (UVB) from the sun. However, when greenhouse gases are released from ground level, they move up into the ozone layer and essentially damage this layer. Reductions in stratospheric ozone levels lead to higher levels of UVB reaching the Earth’s surface. Consequently, laboratory and epidemiological studies demonstrate that UVB can cause nonmelanoma skin cancer and can also play a major role in the development of malignant melanoma. Holes in the ozone layer have been linked to increased cases of skin cancers for some time now, and according to a new study lead by University of California, Berkeley, chronic exposure to ground level ozone itself is now being linked to cardiovascular disease and even premature death.
