2008年世界卫生组织发布空气污染导致的死亡人数预测数据时,室外污染死亡人数为130万,而室内污染死亡人数为190万人。
But a change in research methods makes comparison difficult between the 2008 estimate and the 2017 figures, Neira said.
Neira说由于调查方法的改变,难以对2008年与2017年的数据进行比对。
In the past, for example, the WHO did not take into account the overlap between exposure to both forms, and only assessed urban pollution.
例如,以前世界卫生组织并没有考虑室内室外交叉的部分,并且只统计了城市污染的部分。
Satellite imagery has made it easier to assess rural pollution, and new knowledge about the health impact of exposure has enabled a better count.
卫星图像使调查乡村的污染变得更加容易,并且关于影响健康的风险因素的新知识让我们可以做一个更好的统计。
"The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes," said Neira.
“空气污染的危害远远超过以前我们所知道的,尤其是对于心脏病与中风。”Neira说。
"Few risks have a greater impact on global health today than air pollution. The evidence signals the need for concerted action to clean up the air we all breathe."
“没有什么会比空气污染给全球健康带来更大的危害。这些证据说明我们必须采取行动净化我们的空气。”
