该方法足够灵活，所以原则上讲，人民其他生活质量的重大变化，例如污染物总排放量的减少和犯罪率的下降，也是可以被包括在内的。

Their approach is flexible enough that in principle other important quality-of - life changes could be incorporated — for example , decreases in total emissions of pollutants and declines in crime rates .

比如，挥发性有机物是化学性污染物，在我们的学校，家里以及办公室都能发现它们。

For example , volatile organic compounds are chemical pollutants that are found in our schools , homes and workplaces .

这些化学污染物据美国清洁空气法案定义，目前还不在空气污染物的标准中。

These chemical pollutants are currently not a criteria air pollutant , as defined by the U.S. Clean Air Act .

带着这个问题，我开始了研究，我很快发现室内空气污染物是罪魁祸首。

With this question in mind , I started researching , and I soon found that indoor air pollutants were the culprit .

他们说，虽然这是初步研究，仍需确认，但人们必须做更多的工作来清理海洋污染物。

They say while this is preliminary research , which needs to be confirmed , more must be done to clean up the oceans .

但是很快，我建立了一个新型的数学模型，从本质上量化了这些环境污染物对哮喘病人肺部健康的影响。

But soon after , I developed a novel mathematical model that essentially quantifies the effect of these environmental pollutants on the lung health of asthmatic patients .

我一发现这一点，就调查了四种广布的空气污染物的关系，和他们对哮喘病人肺部健康的影响。

As soon as I realized this , I investigated the underlying relationship between four prevalent air pollutants and their affect on the lung health of asthmatic patients .

起初，我只是想弄清楚，这四种污染物中哪一种对于哮喘病人的肺部健康来说是最有害的。

At first , I just wanted to figure out which of these four pollutants have the largest negative health impact on the lung health of asthmatic patients .

所以我对这项研究很感兴趣，我非常希望能够继续研究，将它扩展到研究除了哮喘病之外的更多的疾病，更多的呼吸系统疾病以及更多的污染物。

So I 'm very passionate about this research and I really want to continue it and expand it to more disorders besides asthma , more respiratory disorders , as well as more pollutants .

The people 's governments of provinces , autonomous regions and municipalities directly under the Central Government may establish their local standards for the discharge of pollutants for items not specified in the national standards ;

这让我感到惊奇，因为这些化学污染物，根据我的研究，我发现他们对哮喘病人的健康有极其负面的影响，因此应该被列入规范中。

Which is surprising to me , because these chemical pollutants , through my research , I show that they had a very large negative impact on the lung health of asthmatic patients and thus should be regulated .

因为，请记住，我们百分之九十的生活都是在室内，空气质量和空气污染物对哮喘病人的肺部健康有巨大的影响，这不止是对那些患有呼吸系统紊乱的人，还有对我们所有人而言都一样。

Because remember , we spend 90 percent of our lives indoors . And air quality and air pollutants have a huge impact on the lung health of asthmatic patients , anyone with a respiratory disorder and really all of us in general .
