美国辛辛提纳大学环境遗传学中心专家利用婴儿脐带血所作的研究发现,汽车尾气污染与胎儿发育过程中的一种基因变化有关,而这种基因变化增加了幼儿患哮喘的风险。这是科学家首次将污染与基因变化联系在一起。研究人员用背包监测仪监测了56名孕妇在怀孕期间所接触的多环芳香烃(PAHs)的水平,并对其所生婴儿的脐带血进行研究,监测其肺部的一种基因(ACSL_3)活化情况。多环芳香烃是交通污
A study by experts at the Center for Environmental Genetics at the University of Cincinnati in the United States found that car exhaust pollution is associated with a genetic change in the development of the fetus and that genetic changes increase the risk of asthma in young children. This is the first time scientists have linked pollution to genetic changes. The researchers used a backpack monitor to monitor the levels of polycyclic aromatic hydrocarbons (PAHs) that 56 pregnant women come into contact with during pregnancy and studied the cord blood of infants born there to monitor one of its lung genes (ACSL_3) Activation. Polycyclic aromatic hydrocarbons are traffic pollution
