In Hong Kong, there were two types of API: General API and Roadside API. The EPD reported the latest APIs hourly. The index and the air quality objectives were set in 1987; and pollutant levels are measured over varying periods, in μg/m 3. There are hourly, 24-hour and annual targets for sulfur dioxide and nitrogen dioxide, and 24-hour and ...
