How does photochemical smog affect humans?
2 reasons
1. Photochemical smog can worsen respiratory problems, such as asthma and bronchitis, as it contains high levels of pollutants like ozone and nitrogen dioxide. These pollutants can irritate the lungs, leading to difficulty breathing, coughing, and other respiratory symptoms.
2. Prolonged exposure to photochemical smog can also increase the risk of developing cardiovascular problems, such as heart attacks and strokes. The pollutants in smog can cause inflammation and damage to the cardiovascular system, leading to an increased risk of heart disease and other related conditions.
