ABSTRACT

............................................................................................................................................................................................................................................

Ozone layer, a natural sunscreen of earth, shields human beings from harmful ultraviolet radiation of the Sun. Ozone is a toxic, unstable gas and naturally present in the stratosphere zone of atmosphere. Ozone layer absorbs ultraviolet radiation and thus prevent from reaching on the Earth's surface. When destruction of stratospheric ozone increases with respect to its production, this phenomenon alters ozone balance and aggravates ozone depletion.Natural phenomena and man-made compounds such as chlorofluorocarbons cause ozone depletion and thus allow ultraviolet radiation to arrive at earth. Small amounts of ultraviolet radiations are essential in the production of vitamin D but excess exposure develops oxidative stress by generating reactive oxygen species (ROS). These reactive oxygen species has genotoxic and carcinogenic effects and produces various organ disorders. The adverse effect of ultraviolet radiation can be neutralized by phytochemicals. Phytochemicals are non-nutritive plant chemicals (viz. lycopene in tomatoes, isoflavones in soy and flavanoids in fruits) that act as antioxidant and neutralize the free radicals generated during exposure of ultraviolet radiation.

 

Key Words: Ozone depletion, phytochemicals, reactive oxygen species, ultraviolet radiation.
