Prolonged exposure to severe air pollution may lead to long-term health issues, such as breathlessness, skin allergies, eye infections, and coughing. According to European Environment Agency, short and long term exposure to air pollution also raises the risk of heart stroke, chronic obstructive pulmonary disease, trachea, bronchus and lung cancers, aggravated asthma and lower respiratory infections. The World Health Organisation (WHO) has also provided evidences of links between exposure to health pollution and type 2 diabetes.
