空气是人类赖以生存的必定条件，而我国的经济开展带来的空气污染疑问就日益彰显出严峻性和迫切性。清华首个室内PM2.5污染大数据调研报告显现：相对于室外PM2.5污染，室
Air is a necessary condition for human survival, and China's economic development brought by air pollution question is increasingly showing serious and urgent. Tsinghua's first indoor PM2.5 pollution big data research report shows: compared with outdoor PM2.5 pollution, room
内PM2.5污染对人的影响更显着，人均室内PM2.5摄入量为室外的4倍；并且室内除了PM2.5，还有甲醛、苯等污染物，在客观条件不变的情况下，人的自动做法对室内空气质量影响最为显着······尽人皆知，孩童留在家里的时刻相对来说更长，这意味着室内的空气污染给他们带来了更大的疾病风险。
Effects of PM2.5 pollution on people more significantly, the per capita PM2.5 intake is 4 times of indoor outdoor and indoor; in addition to PM2.5, there are formaldehyde, benzene and other pollutants in the objective conditions remain unchanged, it automatically impact on indoor air quality was most significant, as everyone knows, the children stay at home time is relatively longer, which means that the indoor air pollution has brought greater disease risk to them.
一项新研讨标明，空气污染可对孩童形成不良影响，并且这种影响甚至在他们出世之前就现已开端了。研讨人员调查了孩童接触多环芳烃(PAH)——一种因焚烧汽油、柴油燃料、家庭取暖燃油和燃煤发生的污染物——的情况。他们发现，产前露出于这些化合物与孩童大脑的构造改变和孩童期智力缺陷和做法疑问有关。
A new study shows that air pollution can have a negative effect on children, and this effect is even before they are born. The researchers looked at children's exposure to polycyclic aromatic hydrocarbons (PAH) - a case of burning gasoline, diesel fuel, household heating oil and coal burning pollutants. They found that prenatal exposure to these compounds is related to changes in the structure of the brain in children and childhood intellectual deficits and practices.
研讨人员测定了空气中、40名孕妈妈妊娠晚期的血液和尿液中，及其后代尿液中的PAH浓度。在这些孩童年满7至9岁前，研讨人员一直对他们保持着追寻，并对他们的大脑进行了M.R.I.(磁共振成像)检查。研讨结果宣布在《美国医学会杂志：精神病学》(JAMAPsychiatry)上。
The researchers measured the concentrations of PAH in the blood and urine of pregnant women and 40 pregnant women in their late pregnancy. In these children from 7 to 9 years old, researchers have been keeping track of them, and their brain M.R.I. (magnetic resonance imaging) examination. The findings were published in the Journal of the American Medical Association: Psychiatry (JAMAPsychiatry).
PAH的露出程度越高，孩童大脑左半球白质表面积的削减就越显着。而白质损害的程度与留意缺陷多动妨碍和别的做法疑问的表现目标得分较高直接有关。
The higher the level of PAH exposure, the greater the reduction in white matter surface area in the left hemisphere of the brain. The degree of white matter damage is directly related to the high score of attention deficit hyperactivity disorder and other methods.
PAH露出较高及白质损害也与处理速度，即人脑获取新信息并对此作出反应的才能)测试得分较低有关。
PAH showed higher and white matter damage as well as processing speed, i.e., the ability of the human brain to acquire new information and respond to it.
“每个人都会接触到这些化合物，”洛杉矶孩童医院心智开展学会的主任布拉德利·S·彼得森博士说。“孕妈妈和儿童对损害大脑发育的环境污染物非常灵敏，露出于这些污染物很可能形成灾难性的影响。”怎么防止这种灾难性的要挟？当室外空气污染严峻时，父母应适当削减孩子的外出时刻；而室内空气污染严峻时，当然不是削减孩子呆在室内的时刻，相反应当根绝室内空气污染对孩子的损害。
"Everyone will be exposed to these compounds," said Bradley S, Ph.D., director of the Institute for mental development in Losangeles children's Hospital, dr.. "Pregnant mothers and children are very sensitive to environmental pollutants that damage the brain's development, and these pollutants are likely to have catastrophic effects." How to prevent such a catastrophic threat? When the outdoor air pollution is serious, the parents should be appropriate to reduce the child out of time; and indoor air pollution is serious, of course, is not to cut children to stay indoors time, but instead should eradicate indoor air pollution on children's injury.
