That's because it will be shot up into the sky, becoming airborne ash particles.

那是因为它们会被喷射到天空，并变成空气中的火山灰颗粒。

IQAir measures air pollution based on the presence of airborne particles that damage the lungs.

IQAir根据空气中含有的对肺部有害的颗粒物的浓度来测量空气污染水平。

She and her colleagues study microscopic airborne particles, so normally we don't collect during rain.

她和同事们研究只有 显微镜下才可见的的大气微粒，因此通常，我们不会在下雨时收集。

Bush fires produce particulate matter pollution, which are airborne particles small enough to enter the lungs.

丛林大火会产生颗粒物污染，颗粒物是空气中的微小颗粒，可以进入肺部。

Their hypothesis is that the catalyst was pollution-specifically, small airborne particles that might carry the virus on their surfaces.

他们的假设是，催化剂是污染物——具体来说，就是空气中携带病毒的小颗粒。

The information is based on satellite data used to estimate the effects of increased airborne fine particles on life expectancy.

这些信息基于卫星数据，研究人员利用这些数据估计空气中细颗粒物增加对预期寿命的影响。

The report called for cuts in worldwide levels of lung-harming airborne particles to levels sought by the World Health Organization (WHO).

该报告呼吁世界各国将对肺部有害的空气颗粒物水平降低到世界卫生组织要求的水平。

Unlike viruses that proliferate through small, airborne particles, Ebola only exists in bodily fluids, such as saliva, blood, mucus, vomit, or feces.

与其它的病毒不同，埃博拉仅存于体液中，比如唾液、血液、粘膜、呕吐物或粪便中。

Airborne particles may turn out to be more of a concern than those in food.

空气中的颗粒可能比食物中的颗粒更令人担忧。

And they aren't talking, that could limit the spread of airborne particles from one person to another especially if everyone is wearing a mask.

而且他们不说话，这可能会限制空气中的粒子在人与人之间的传播，尤其是如果每个人都戴着口罩的话。

Photochemical smog and airborne particles from vehicle emissions affect many rapidly developing cities, from Mexico City and Santiago to New Delhi and Tehran.

车辆排放的光化学烟雾和空气中的颗粒物影响着许多快速发展的城市，从墨西哥城和圣地亚哥到新德里和德黑兰。

The level of emissions they cause will depend on how the electricity to run them is generated, while brakes, tyres and roads all create tiny airborne particles as they wear out.

电动汽车造成的污染排放水平取决于如何产生汽车运行需要的电力，而刹车、轮胎和道路在磨损时都会产生微小的尘埃粒子。

Its guidance temporarily said there was evidence that when an infected person coughs, sneezes, talks, sings or breathes, infectious droplets and airborne particles could stay in the air and travel distances beyond six feet.

有证据表明当感染者咳嗽、打喷嚏、说话、唱歌或呼吸时，传染性飞沫和空气中的微粒可能会停留在空气中，且传播距离超过6英尺。
