Li Ganjie said, in 2013, the national total emissions of chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides are respectively 2352.7, 245.7, 2043.9 and 22273000 tons, down 2.9%, 3.1%, 3.5% and 4.7% respectively over the previous year. In general, the national environmental quality situation has improved, but the protection of the ecological environmentsituation is still grim.

On the basis of the new "ambient air quality standard" (GB 3095-2012) ofsulfur dioxide, nitrogen dioxide, respirable particulate matter (PM10), fine particles (PM2.5), to evaluate the carbon monoxide and ozone 6 pollutants, 74 new standards to monitor the implementation of the first stage city, ambient air quality standard was only 4.1%. The air quality was relatively good before the 10 city is Haikou, Zhoushan, Lhasa, Fuzhou, Huizhou, Zhuhai, Shenzhen,Xiamen, Lishui, Guiyang City, the top 10 relatively poor air quality in Xingtai,Shijiazhuang, is Handan, Tangshan, Baoding, Ji'nan, Hengshui, Langfang and Zhengzhou, xi'an.

The other 256 city implementation of the old air quality standards, compliance percentage 69.5%; acid rain distribution mainly in the area along the Yangtze River and downstream to the south, an area of about10.6% of the total land area.

In the 61 lakes monitoring nutritional status (reservoir), eutrophication lake(reservoir) accounted for 27.8%, including mild, moderate eutrophic lake(reservoir) rates were 26.2%, 1.6%; in 4778 groundwater monitoring points,monitoring points, poor and very poor water quality ratio of 59.6%.

The national sea water quality overall downward trend. The four sea areas,water quality of the Yellow Sea and the South China Sea is good, the water quality of Bohai coastal waters, coastal sea water quality is poor; 9 importantbays, Liaodong Bay, Bohai Bay and Jiaozhou bay water quality is poor, the Yangtze River Estuary, Hangzhou Bay, Minjiang port and the water quality of the Pearl River Estuary.
