Ozone in the atmosphere STRATOSPHERE TROPOSPHERE In this region, ozone protects In this region, ozone can us from the sun's harmful damage lung tissue and uitraviolet radiation

The discovery of the ozone hole The British Antarctic Survey has been monitoring for many years, the total column ozone levels at its base at Halley bay in the antarctica Monitoring data indicate that column ozone levels have been decreasing since 1977. This observation was later confirmed by satellite

Whether and climate Weather is the condition of the atmosphere in terms of temperature, humidity, winds and precipitation Climate is defined as the average weather over various time periods ranging from a few weeks to decades to geological timescales Whether and climate are ultimately determined by location, topography, and the exchange of radiant energy between the Sun, Earth, and space

Air quality and particles Epidemiological(流行病学) evidence associates atmospheric particles with diseases and mortality Particles penetrate the lungs, blocking and irritating aIr passages. Particles themselves could exert toxic effects. ( toxic substances present in the particles [polycyclic Aromatic Hydrocarbons are examples of toxic substances in aerosols.]
