Transcript of Effects of Air Pollution to human health

To Human health Individuals at Risk How Pollution Hurts Us Acute Effects While everyone can potentially suffer from air pollution, there are individuals who are more susceptible than others. In general, living in an urban setting where there are lots of cars and buildings releasing pollutants increases a person's risk of health problems. Joggers and bikers who exercise on smoggy days expose their bodies to vast amounts of pollution each time they go out. Both the elderly and children seem to be especially sensitive to pollutants in the air. Exposure to air pollution is associated with numerous effects on human health, including pulmonary, cardiac, vascular, and neurological impairments. The respiratory system is responsible for bringing large amounts of air into the body, and then transporting oxygen from that air into the blood system. Eventually the oxygen is carried to the heart, where it then becomes part of the cardiovascular system. However, polluted air that works its way through the respiratory and cardiovascular systems can cause problems. High-risk groups such as the elderly, infants, pregnant women, and sufferers from chronic heart and lung diseases are more susceptible to air pollution. Children are at greater risk because they are generally more active outdoors and their lungs are still developing. Exposure to air pollution can cause both acute (short-term) and chronic (long-term) health effects.   are usually immediate and often reversible when exposure to the pollutant ends. Some acute health effects include eye irritation, headaches, nausea, headaches, tiredness, dizziness, nausea, and throat irritation. The Effects of Air Pollution Chronic Effects Chronic effects are usually not immediate and tend not to be reversible
