Since the beginning of this year, the average number of haze days in China has been 29.9 days, which is 10.3 days more than the same period in previous years and the highest in history since 1961. Zhao Hongmei, director of the Department of Respiratory Medicine of China Rehabilitation Research Center, said in a video interview with chinanews. com today that PM2.5 will cause tracheitis, asthma and other diseases, and will also affect the human cardiovascular system. However, there is indeed no relevant research and record in China on whether haze causes infertility.
Which systems of the human body are affected by haze, Zhao Hongmei said: Regarding this issue, we have defined 'PM2.5'. PM2.5 is actually particles with a diameter of less than or equal to 2.5 microns, which are easily precipitated in the human alveoli and then carry pollutants such as viruses, bacteria, and heavy metals, which can be engulfed by alveolar cells. It can cause diseases such as bronchitis and asthma. In addition, it can also affect the human cardiovascular system, leading to People's existing coronary heart disease, ischemic disease, etc. have worsened
Regarding the impact of haze on the reproductive system, there is a study abroad that included more than 74000 women of childbearing age in Europe from 1994 to 2011, all of whom were single birth women. Regarding the birth rate of low birth weight infants, researchers found that if PM2.5 was reduced by 10 micrograms, the birth rate of low birth weight infants would decrease by 22%. Therefore, from this perspective, haze may have an impact on the low birth weight of infants
Regarding the issue of whether haze affects the reproductive system and leads to infertility, Zhao Hongmei said, "I have also searched a lot of literature on this issue, and there is indeed no relevant research or record in China. In foreign studies, there are about forty to fifty studies suggesting that it may have an impact on pregnancy rates, and there is no clear indication of infertility. Whether it causes fetal malformations, low birth weight infants, etc., further research is needed to confirm whether it will cause such an impact
