| What Are The Major Harmful Effects Of Ozone Depletion On Human Health ?
Along with the ultraviolet rays (UVB) that ozone absorbs and which have a high amount of energy, a risk to the health of humans is also posed by the increased amount of ozone in the troposphere, resulting from a greater amount of ultraviolet radiation reaching the surface of the Earth. |

Sunlight’s capacity for synthesis of Vitamin D also increases on account of more ultraviolet radiation at the Earth’s surface, which may be a beneficial effect of depletion of ozone since Vitamin D can help prevent cancer.Here are some of the major harmful effects of ozone depletion on human health:
Basal and Squamous Cell Carcinomas -- These are the most common skin cancers. The replication of DNA develops errors in transcription, due to the formation of dimers by the DNA molecule’s pyrimidine bases, on account of UVB being absorbed. Fatalities on account of such cancers are uncommon. A 2 percent increase in the number of cases can be expected, when atmospheric ozone decreases by 1 percent.
Malignant Melanoma -- Fifteen to twenty percent cases end up as fatalities, but it is not clear as to how UVA and UVB impact malignant melanoma, even as these do appear to have an impact and that has been established by several studies.
Cortical Cataracts -- An association has been suggested between this disease and ultraviolet radiation by studies, even as the degree of likely impact has not been clearly established yet. The impact may vary according to gender and race as well.
Increased Tropospheric Ozone -- The properties of ozone as an oxidant can harm human health and more ozone in the troposphere due to more ultraviolet radiation can be dangerous. Gases emitted from automobiles produce ozone, when acted upon by such radiation.
