一般来说，“粗尘”，也称为“颗粒物”，是指在空气中的颗粒物，可以对大气质量产生物理和化学变化。它是空气污染的重要组成部分。

Coarse dust contains a variety of biological and chemical substances, such as pollen, soot, smoke, dust, ashes and other aerosol particles. It also includes particles emitted from motor vehicles, industrial processes, and other sources of air pollution. Coarse dust is easily inhaled and can significantly reduce visibility.

粗尘含有各种生物和化学物质，如花粉、烟灰、烟雾、灰尘、灰烬等气溶胶颗粒。它还包括汽车、工业过程和其他空气污染源排放出的颗粒。粗尘容易被吸入，会显著降低能见度。

Coarse dust is a major pollutant of the air and its particles can be dangerous to health. Studies have shown that exposure to levels of coarse dust can cause serious respiratory problems, such as asthma, bronchitis and other respiratory illnesses. Long-term exposure can also lead to reduced lung function, heart attacks and even premature death.

粗尘是空气中的主要污染物，其颗粒对健康有害。研究表明，暴露在粗尘水平中可能会导致严重的呼吸问题，如哮喘、支气管炎和其他呼吸疾病。长期暴露还会导致肺功能减弱、心脏病发作，甚至早逝。

To reduce air pollution from coarse dust, governments around the world have implemented regulations that require industries and vehicles to use less polluting technologies and fuels. Governments also encourage the public to reduce their own emissions of the pollutant by not burning wood in open areas and reducing their use of vehicles.

为了减少粗尘对大气的污染，世界各国政府实施了法规，要求工业和车辆使用更少污染技术和燃料。政府还鼓励公众减少自己排放污染物，不在露天燃烧木材，减少车辆使用。
