越来越多的儿童患有先天性呼吸道疾病。一些报告指出，空气污染会通过母亲导致先天性呼吸道疾病。当母亲在怀孕期间暴露在空气污染中，胚胎也会受到影响。结果许多儿童患有先天性呼吸道疾病。因此，不仅成年人，而且儿童也受到空气污染的影响。空气污染在孩子出生之前就会影响他们。当它们的母亲接触到高浓度的污染物时，这些污染物会通过胎盘和脐带血进入胚胎的循环。环境工作组的研究人员与美国纽约的公益性组织合作，声称污染物可以通过母体进入胚胎体内。这些污染物进入胚胎体内后，会增加宫内发育迟缓、低出生体重、早产和围产期发病率。“来自中国的孕妇暴露在高水平的二氧化硫和颗粒物污染环境中，会增加早产和低婴儿出生体重的风险。“当儿童吸入和成年人一样多的污染物时，会造成更严重的影响，因为儿童的呼吸系统没有完全发育。此外，由于儿童比成年人有更多的活动，他们会吸入更多的污染物。因此，空气污染对儿童造成更严重的影响。大多数环境空气污染物是化学物质。几种氧化性空气污染物是呼吸系统的主要原因。它们阻碍了通路的信号。它们还被证明会增加过敏原，增加哮喘恶化的风险，降低肺功能。它们还会影响儿童呼吸系统的发育.

More and more children suffer congenital respiratory disease. Some reports point out air pollution can result in congenital respiratory disease through their mothers. When mothers are exposed to air pollution during their pregnancies, the embryos are also affected. It results that many children suffer congenital respiratory disease. Therefore, not only adults but also children are affected by air pollution.Air pollution can affect children before they are born. When their mothers are exposed to high levels of pollutants, these pollutants can enter the embryos’ circulation through the placentas and umbilical cord blood. The researchers, in the Environmental Working Group, who collaborated with Commonweal in New York, USA, claimed that the pollutants could enter embryo bodies through their mothers. After these pollutants enter embryos’ bodies, it will increase the rate of intrauterine growth retardation, low birth weight, pre-term birth, and perinatal morbidity. “Pregnant mothers from China exposed to high levels of ambient sulfur dioxide and particulate matter pollution have been shown to have the increased risk of preterm delivery and low infant birth weights.”When children inhale the same amount of the pollutants as adults, it causes more serious effects because children’s respiratory systems do not completely develop. In addition, because children have many activities than adults, they inhale a greater amount of pollutants. Therefore, air pollution causes more serious effects on children. Most of the ambient air pollutants are chemicals. Several oxidant air pollutants are the main causes of the respiratory system. They obstruct the signals of pathways. They also have been proved to enlarge allergens, enlarge the risk of worsening asthma and reduce lung function. They also affect the growth of children’s respiratory systems.
