Material and methods: A narrative review of the literature was done based on searched databases. All relevant studies published 1998 until 2021 gathered. According to the databases, 360 articles were retrieved. 24 studies were screened after review and 16 full-text articles entered into the analysis process. Finally, 9 articles were selected in this study. Results: The results of this study showed that industrialization, increasing urbanization, technological development, rapid population growth, increased desertification and deforestation, occurrence of dust phenomenon, uncontrolled growth of motor vehicles, entry of various pollutants and environmental degradation cause a phenomenon called air pollution. Based on the results, the toxic air pollutants causes many health endpoints in human such as respiratory disease, asthma, chronic lung disease, respiratory and cardiovascular system dysfunction, decreased immune system, headache, dizziness, gastrointestinal disease and increased risk of cancer (lung, stomach, intestine, eye, liver and brain). Conclusion: According to research related to the subject, air pollution is a positive function of energy consumption, volume of industrial activities, and the uncontrolled increase of human activities. The most vital factors are increasing the level of public awareness, reducing the exposure to toxic air pollutants, improving quality of the products and consumption of consumed fuels. |
