Ozone is a major element of urban smog.
Ozone can lower resistance to diseases such as colds and pneumonia, damage lung tissue, intensify heart and lung disease, and cause coughing and throat irritation. Even healthy adults who perform heavy physical exercise or manual labor outdoors experience the unhealthful effects of ozone. Other sensitive persons include the young, elderly, and those with pre-existing lung problems. Ozone is a colorless gas that can be found in the air we breathe. Each molecule of ozone is composed of three atoms of oxygen, one more than the oxygen molecule which we need to breathe to sustain life.
