Beijing:- Air pollution does not just affect our health, but also affects our knowledge skills. This has been revealed in a study done in China. It has been reported that due to the pollution in the air, the probability of getting lesser marks in verbal and math test increases. This study has been published in a journal called PNAS.
Research:- Researchers say that this new study tells that air pollution affects society more than our predictions. A senior research fellow at the US-based International Food Policy Research Institute and Professor Jiyab Zhang, at Peking University in China, says that long-term exposure to air pollution prevents the ability to perform oral and math examinations. He further says, due to damage to nongiction by air pollution, the development of human capital hampered. Even before, many studies have shown that the effect of air pollution is on nounative abilities. However, it has been revealed for the first time that this affects the ability of the person to speak and mathematics.
According to the researchers, the level of pollution and long stay in contact with it have affected both scores of oral and math examinations. This has reduced the ability of the person to speak. Compared to women, its effect was more on men. Zhang says, with the aging, the impact of air pollution becomes more visible. It increases apprehensions of elderly people suffering from Alzheimer’s and dementia.
32,000 people:- The researchers included about 32,000 people for the study. It was noted in the study that the effect of staying in touch with short-term and long-term air pollution is how much and how much falls on knowledge related skills.
World Health Organization:- It has also been reported in the study that if the micro particles in the air are limited to 50 micrograms per cubic meter in the air according to the US Environmental Protection Agency (EPA) standard, then it can improve the number of oral and math exams. Zhang says, many developing countries including China are battling this problem. According to the World Health Organization’s database, the world’s top 20 most polluted cities are in developing countries. Cities with low and middle income countries whose population is more than one lakh, fail to meet the WHO’s air quality guidelines.
