Air pollution has been shown to impair growth of the lungs in children, which will have an impact for the rest of their life. Their immune system is also not fully developed and their lungs are still growing. As a consequence, they inhale more pollution. Pollution has been shown to decrease life expectancy due to earlier death from cardiovascular and respiratory diseases and lung cancer.Ĭhildren are generally more active, engage in more outdoor activities than adults, and breathe more rapidly, even with the same level of activity. Lifetime exposure to air pollution can have a range of effects in adults and children, leading to long-term problems, such as asthma, chronic bronchitis and heart diseases. Health registries also report more cases of death from these problems on days with higher pollution levels. Research has shown an increase in doctors’ consultations, emergency hospital visits and hospital admissions for asthma and heart conditions, such as heart attacks, on days with higher pollution levels. Studies have shown an increase in wheezing, cough and attacks of breathlessness with a reduction in lung function and need for medication when pollution levels are increased. The symbol for this is: μg/m3 Short-term problemsĪir pollution is known to trigger heart attacks in people with cardiovascular diseases and to exacerbate symptoms for people who already suffer with lung conditions, such as asthma and chronic obstructive pulmonary disease (COPD). The measurement commonly used is the number of micrograms of pollution per cubic meter. Levels of air pollution are often measured by the mass per volume of air. For example, PM10 refers to particulate matter that is up to 10 micrometers in size. The consequences are due to the whole mixture.ĭifferent types of particulate matter are measured by their size. There is not one single pollutant that is responsible for all the adverse effects. The interactions between these pollutants and the different levels of pollution can produce a range of health effects, both in short term (within hours and days) and long term (after a number of years). There are many different pollutants in the air. Factors such as current health conditions, age, lung capacity, lifestyle and time spent in polluted air can all influence how pollutants affect overall health. Pollution also has a serious effect on the heart and circulatory system and increases the risk of heart attacks.Īir pollution affects people in different ways. The lungs are the first point of entry for air pollution into the body and are therefore the first affected organ. Air pollution has a negative impact on human health and exposure to it can affect 100% of the population, from unborn babies to the very elderly.
