THE Environmental Protection Department (EPD, 環境保護署) has released a report on air pollutants in Hong Kong recorded in 2016. The pollutant that had the highest amount recorded was nitrogen oxide (氮氧化物), at 89,640 tonnes.
Because Hong Kong has a lot of regulations on air pollution from power stations, ships and cars, the amount of those substances sent out have lessened by four to 11 percent when compared to 2015 levels. And the 2016 levels are even 39 to 78 percent less than that of 1997.
The EPD releases data on what sort of pollutants are in the air every year and what sort of machinery, such as power stations, ships, cars, aeroplanes, etc, send out which kind of pollution. Of the pollutants, there are six types, such as sulfur dioxide (二氧化硫), nitrogen oxide, carbon monoxide (一氧化碳), etc.
