The environment air quality report of the first three months of this year was released by Ningbo Environmental Protection Bureau on April 11. According to the report, the rate of excellent air quality days of the whole city stood at 88.9%, there were no heavy-pollution days, and the index of the PM2.5 witnessed a continuous decrease. In terms of the specific areas, Xiangshan County, Ninghai County and Fenghua District are the top three areas with relatively good air quality.

According to the monitoring statistics, from January to March this year, the comprehensive air quality index of the state control spots in Ningbo reached 4.41, and the rate of excellent air quality days stood at 88.9%, down by 2.2 percentage points over the same period of 2017. "The decrease of the excellent rate is mainly due to the poor air quality of January." said a technician from Ningbo Environment Monitoring Center. As the average temperature of January this year was relatively lower, and the cold air from the north brought with it the pollution air mass, resulting in the poor air quality of the month.

As for the other monitoring statistics, in the first quarter, the average density of the PM2.5 of the state control spots stood at 45 microgram per cubic meter, down by 2.2% over the same period of last year. And likewise, the average density of such pollutants as PM10, SO2, NO2 and O3 witnessed downward trend.
