15. Discuss the following facts and figures.

  1. As a result of human activity 156 mln. tons of sulphur dioxide and 60 mln. tons of nitric oxide are released into atmosphere every year. In the cities where there are many industrial enterprises the air is contaminated even greater. For example, in Tokyo every month 34 tons of soot falls per each square kilometer of the territory, in New-York it amounts 17 tons.

  2. As a result of industry and transport development oxygen is used for burning in greater amount. For example, an automobile spends a man’s daily rate (суточная норма) of oxygen per 1,5 thousand kilometers. (A man spends 500 liters of air daily on average). A modern jet liner uses 35 tons of oxygen per 1 transatlantic flight.

In all nearly 50 tons of nuclear material were released into the atmosphere. The mass of radioactive bomb fallen on Hiroshima was 4,5 tons.
