Explanation: 

Detailed explanation-1: -PM2.5 can travel deeply into the human respiratory system, reaching the lungs. Exposure to PM2.5 is linked to respiratory and cardiovascular diseases and reduced lung function. 96% of the urban population was exposed to concentrations of fine particulate matter (PM2.5) above the WHO annual guideline of 5 µg/m3.

Detailed explanation-2: -Transportation. The use of private vehicles (particularly older, diesel models) is the major source of urban air pollution. The US Environmental Protection Agency estimates that about 75% of VOC emissions (by weight) come from transportation. About one-quarter of particulate matter in the air is due to vehicles.

Detailed explanation-3: -The underlying causes of air pollution of the city are the processes that are associated with the burning of fossil fuels (production and consumption of energy for heating buildings, industrial activities, traffic). Noise is also a special form of pollution, which burdens the urban population.
