Health problem This problem of increased pollution in the major cities of the world has led to an increase in the number of studies done to look at the effects on our health The results so far are not very reassuring. In fact, air pollution may be a much greater danger to our health than scientists believed before. A 20-lear study of residents of a Cairo suburb shows that the tiny particles in polluted air could lead to three times as many long-term health problems as was previously thought. A connection between the number of particles in the air and health is suggested by Dr Razia of Cairo University He and his colleagues collected data on 25,000 residents of Cairo over two decades. They found th as the number of than 2.5 microns in diameter. increased. so did the tiny particles, those less risk of dying from health problems such as heart attacks and lung cancer
Traffic and asthma
Other studies show a similar link between traffic pollution and ill health.A second group of researchers in Ottawa Canada, reported that children living near busy roads more likely to develop asthma. They studied the health of 250 children in different Canadian cities. The results strong connection between how close a lives to traffic and the possibility of child developing asthma and other similar diseases It is clear from these studies and others that the time has come to start reducing the levels of air pollution in our cities for the sake of our children and future generations.
