这些年一些陈述显现，人类的生殖才能正在显着降低，环境污染被认为是元凶巨恶。来自波西米亚北部的一项查询，对触摸高浓度PM2.5的孕妈妈进行了研讨，发现高浓度的细颗粒物污染物也许会影响胎儿的发育。更多研讨发现，大气颗粒物的浓度与早产儿、新生儿死亡率的上升，低出世体重、宫内发育缓慢，以及先天性功能缺点具有相关性。
In recent years, some of the statements show that human reproduction is significantly reduced, environmental pollution is considered to be the culprit. A study from northern Bohemia, a study of pregnant mothers with high concentrations of PM2.5, found that high concentrations of fine particulate matter may affect fetal development. More studies have found that the concentration of atmospheric particulate matter is associated with an increase in premature infant and neonatal mortality, low birth weight, intrauterine growth retardation, and congenital dysfunction.
PM2.5中具有一些潜在的毒性元素，如铅、镉、镍、锰、钒、溴、锌、苯并(a)芘等多环芳烃(PAH)，主要吸附在直径小于2μm颗粒物上，而这些小颗粒易堆积于肺泡区容易被吸收入血液，进而影响生殖系统健康及胎儿发育。
Has some potential toxic elements in PM2.5, such as lead, cadmium, nickel, manganese, vanadium, zinc bromide, and benzo (a) pyrene and other polycyclic aromatic hydrocarbons (PAH), mainly adsorbed on the particles with diameter of less than 2 m, and these small particles easily accumulate in the alveolar region is easily absorbed into the blood. Then affect the health and fetal development of the reproductive system.
这些颗粒物中的活性成分由母体呼吸道吸入，并吸收入血液，高浓度的生物活性化合物PAH和其含氮衍生物等毒性物质会搅扰母体的一些正常的生理代谢过程，然后影响胎儿的养分与发育；别的，毒物还也许直接经过胎盘对胎儿起作用，毒物的作用很也许是在妊娠早期，尤其是怀孕榜首个月。
The active component of these particles in the inhalation by maternal respiratory tract, and absorption into the blood, bioactive compounds with high concentration of PAH and its derivatives containing nitrogen and other toxic substances will disturb the maternal normal physiological metabolic processes, and effects of nutrient and fetal development; the other, may also directly through the placenta poison effect on fetus. The effects of the poison may be very early in pregnancy, especially pregnant first month.
有研讨者试验查询发现在那些吸烟或是长时间露出于大气颗粒物的妇人胎盘血中DNA加合物的浓度显着增高，此类妇人中胎儿发作宫内发育缓慢、低出世体重的危险性也要高于那些不吸烟的妇人。
Researchers have found that smoking in the test query or placental blood woman long time exposed to atmospheric particulate matter in DNA adduct concentration significantly increased risk of fetal intrauterine growth this woman attack slow, low birth weight is higher than that of those who do not smoke woman.
对其大气细颗粒物也即是PM2.5的潜在健康损害研讨越深化越发现其对人类健康的损害影响越深，若不加操控，或许环境PM2.5掌控的即是人类将来的命运。
The further research on the potential health damage of the fine particles in the atmosphere, that is, the deeper the PM2.5, the deeper the damage to human health, and if it is not manipulated, perhaps the environment PM2.5 control is the future destiny of mankind.
