This study aims at investigating the air pollution caused by polluting gases, its spatial and temporal variation, and its impact on human health in Al-Waziriya region in Baghdad, as it is one of the big important cities. The study of air pollution with polluting and harmful gases is one of the most important studies, because air is the most important element for survival. A human may be able to go for several days without food and water, but not without air, which is necessary for breathing. There is an urgent need to study air pollutants and their effects on humans, whether in terms of health or psychologically.
