An alarming global environmental disaster that harms public health is air pollution. Given that an adult breathes in between 10-15 m3 of air each day on average, it is clear that inhalation is the primary way that humans are exposed to airborne pollutants. Lahore, Pakistan's second-largest city, is the most polluted metropolis in the country and is increasing at a pace of 4% yearly. Pakistan is thought to be the fastest urbanizing country in South Asia. Haze frequently affects urban areas in Asia, and Lahore is a rapidly growing metropolis. This review focused on examining and comparing Lahore's air quality index (AQI) values under various sites and conditions, such as smog, traffic, industrial estates and brick kilns and their relationship to adverse effects on human health. The provincial capital of Punjab, Lahore, has been designated as the world's most polluted city when its AQI exceeded 400 in November, 2021. Lahore's air pollution is caused by a variety of factors, including industrial and automobile emissions, haze, smoke from brick kilns, burning of crop residue and other garbage, and dust from building sites. Carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2), aerosol optical depth (AOD), methane (CH4), and formaldehyde are the main primary and secondary air pollutants that contaminate the air (HCHO). The signs and symptoms of air pollution are moderate cough, persistent cough, dyspnea, eye problems, low-grade fever, pulmonary diseases, peribronchial...
