The Eiffel Tower disappeared behind a brown smog on Wednesday as Paris and much of northern France suffered a spike in pollution.
周三,埃菲尔铁塔消失在一片棕色雾霾之中,因为整个巴黎还有北欧的大部分地区的污染飙升。
“The pollution levels are consistent. If we don’t go over the alert level, we won’t be far away, said Airparif, the body responsible for monitoring air quality in the greater Paris region.
“污染值始终如一。如果我们不超过警戒线,就不会太糟,法国大巴黎地区空气质量监测网协会说道。
In Paris, authorities measure the concentration of particulates with a diameter of less than 10 microns – so-called PM10 – in the air to determine pollution levels.
在巴黎,官方测量了空气中微小颗粒的浓度,直径小于10微米的颗粒——所谓的PM10——决定了空气中的污染指数。
These particulates are created by vehicles, heating and heavy industry, and include the most dangerous particles that measure less than 2.5 microns in diameter, which can penetrate deep into the lungs and the blood system and can cause cancer.
机动车辆、暖气和重工业产生了这些空气中的微小颗粒,并且包括最危险的直径小于2.5微米的颗粒,它们会渗入肺部和血液系统引起癌症。
