The study was conducted by researchers at the University of Sydney in Australia, and published its results on Wednesday in the Journal of Intelectual Desability.
To analyze the connection between air pollution and children with mental disabilities, the team analyzed data of more than 18,000 children born in the United Kingdom between 2000 and 2002.
The researchers found that children living in areas where transported particle things are less than 2.5 microns in diameter, 33% more likely to develop mental disabilities than those living in distant areas of pollution.
Selected particles are broadcast mainly from industrial sources, such as auto-exhaust, wood-cooking and smoking, and can be inhaled and installed in the lungs.
The researchers also found that areas with high levels of nitrogen oxides and carbon monoxide increase the risk of mental delay at 30%, while those with high sulfur dioxide sulphurians have a 17% increase.
The air pollution is a contributing risk factor for many diseases, including heart diseases, lungs, cancer and diabetes. The United Nations Children's Fund (UNICEF) revealed that around 17 million creatures around the world breathe into poisonous air, which can damage the development of their brains.
According to a World Bank report in 2016, air pollution kills one of 10 people worldwide, making it the fourth largest factor in the world, and the largest in poor countries, with 93% of deaths or non-fatal diseases.
