fine dust

The blue glow that surrounds the blue Horsehead's eye — and other stars around the image — is a reflection nebula composed of fine dust.

环绕着蓝色马头的眼睛部位的蓝色光芒——与周围其它恒星——是一个由细尘埃组成的反射星云。

Death exists - in a paperweight, in four red and white balls on a billiard table - and we go on living and breathing it into our lungs like fine dust.

无论镇纸中，还是桌球台上排列的红白四个球体里，都存在着死。并且我们每个人都在活着的同时像吸入细小灰尘似的将其吸入肺中。

But the survey did find excessive arsenic content in local Wells, and Greenpeace warns that fine dust pollution might become a problem when the snow has gone.

但是调查确实发现，当地井水中砷的含量增加，而且绿色和平警告说，当积雪消融以后，粉尘污染也许会带来难题。
