Among them, the annual average concentration of sulfur dioxide, nitrogen dioxide, respirable particulate matter (PM10), fine particulate matter (PM2.5) and carbon monoxide in the ambient air meets the national secondary standard; the overall quality of the water environment is improved, and the quality of the main drinking water sources is good. Meets drinking water quality requirements; river water quality achieves historic breakthrough; seawater quality in the coastal waters in the east is maintained at an excellent level, and the pollution of seawater quality in the coastal waters in the west is somewhat reduced; environmental noise in urban areas is at a general (level 3) level; radiation environment In good condition.
It is worth mentioning that Shenzhen's carbon emission intensity (unit GDP carbon emission index) is at an advanced global level, and the city's carbon emission intensity has decreased by 10.9% over the past three years.

According to the latest source analysis results, the contribution rate of dust sources in 2019 has also increased. This is mainly affected by the incomplete implementation of dust pollution prevention measures for construction projects such as rail transit, municipal facilities, and water pollution control throughout the city.
The person in charge said that this year the municipal ecological environment department will comprehensively strengthen supervision and inspection to reduce dust pollution. The bureau will work together with the district and city housing construction, transportation, and water affairs departments to fully implement the "7 100%" construction site dust pollution prevention measures, increase the frequency of road washing, sprinkling, and cleaning. The urban road is suitable for machine scanning. More than%, and at the same time realize "zeroing" of bare soil.
