這些年一些陳述顯現(xiàn)，人類的生殖才能正在顯著降低，環(huán)境污染被認為是元兇巨惡。來自波西米亞北部的一項查詢，對觸摸高濃度PM2.5的孕媽媽進行了研討，發(fā)現(xiàn)高濃度的細顆粒物污染物也許會影響胎兒的發(fā)育。更多研討發(fā)現(xiàn)，大氣顆粒物的濃度與早產(chǎn)兒、新生兒死亡率的上升，低出世體重、宮內(nèi)發(fā)育緩慢，以及先天性功能缺點具有相關性。
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中具有一些潛在的毒性元素，如鉛、鎘、鎳、錳、釩、溴、鋅、苯并(a)芘等多環(huán)芳烴(PAH)，主要吸附在直徑小于2μm顆粒物上，而這些小顆粒易堆積于肺泡區(qū)容易被吸收入血液，進而影響生殖系統(tǒng)健康及胎兒發(fā)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.
這些顆粒物中的活性成分由母體呼吸道吸入，并吸收入血液，高濃度的生物活性化合物PAH和其含氮衍生物等毒性物質(zhì)會攪擾母體的一些正常的生理代謝過程，然后影響胎兒的養(yǎng)分與發(fā)育；別的，毒物還也許直接經(jīng)過胎盤對胎兒起作用，毒物的作用很也許是在妊娠早期，尤其是懷孕榜首個月。
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.
有研討者試驗查詢發(fā)現(xiàn)在那些吸煙或是長時間露出于大氣顆粒物的婦人胎盤血中DNA加合物的濃度顯著增高，此類婦人中胎兒發(fā)作宮內(nèi)發(fā)育緩慢、低出世體重的危險性也要高于那些不吸煙的婦人。
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.
對其大氣細顆粒物也即是PM2.5的潛在健康損害研討越深化越發(fā)現(xiàn)其對人類健康的損害影響越深，若不加操控，或許環(huán)境PM2.5掌控的即是人類將來的命運。
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.
