    Air Pollution Index (API) 空气污染指数

    API (Air Pollution Index) describes the level of air pollution. It is typically used to measure ambient city air quality. The API calculation process considers the pollutant levels of SO2, NO2, PM10, CO, O3. API includes five grades: 0-50 = Good,51-100 = OK,101-200 = Mld Pollution ,201-300 = Medium Pollution,>300 = Heavy Pollution.

    GIGA uses API to measure the quantify air quality during production, enabling the impact of production emissions to be comparable with ambient air quality.

    空气污染指数(API) 体现了空气质量与空气污染程度,通常用于表达城市空气状况。计入该指数的污染物主要包括二氧化硫(SO2)、氮氧化物(NO2)、悬浮颗粒(PM10)、一氧化碳(CO)、臭氧((O3)。空气污染指数划分为五个等级:0~50优,51~100良,101~200轻度污染,201~300中度污染,>300重度污染。每个等级均有相应的污染物限值。
