**API stands for Air Pollution Index(指数).
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.
**Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.
