Explicação:
Air pollution also called atmospheric pollution, refers to the contamination of the air by gases, liquids and solid particles in suspension, biological material and even energy. These substances are called air pollutants and exist in the form of gases or particles from natural sources (volcanoes and mists), or even artificial sources produced by human activities, they can reach dangerous concentrations both outside and inside the home (it is possible that the air is worse inside the house than outside). According to the World Health Organization (WHO), air pollution is responsible for more than seven million deaths per year worldwide - killing more than AIDS and Malaria. Studies reveal that this type of pollution can affect all organs of the human body.
