Increasing globalization, industrialization, population, and burning of fossil fuels have been adversely affecting the environment for a long time. The consequences of the effects can be seen even within a short period of time in the current scenario. The air pollutants such as SO2, NO2, CO, and PM are the main contributors to the adverse health effects. Long-term and short-term exposure to pollutants may cause acute and chronic effects on the human body as they can enter deep into the organ and circulate in the bloodstream. The ultimate purpose of this review is to develop a quantitative perceptive of the existing state of facts about potential health effects concerning the dose-response relationship between exposure level of air pollutants and induced diseases. We have drawn around 376 scientific research papers on high-impact factors related to air pollution and health. These publications were analyzed with consideration of experimental methods, design, observations, and reports on the exposure through inhalation which may emulate the normal direction of exposure inside the human organs. The present study suggests the effects of epidemiological studies on associations between pollutant concentrations and human health. Most of the inferences evidenced the severe adverse effects of particulate matter (PM2.5 & PM10) on the respiratory and cardiovascular systems. Our present investigation reveals the health risk due to pollutants’ exposure to the vulnerable population anguishing with asthma, COPD, cardiovascular disease, diabetes, cancer (physiological diseases); dementia, depression, and stress (psychological diseases).
