Ministry of Environmental Protection made public yesterday the 2010 Report on Environmental Quality of China. The findings of national environmental quality monitoring network show that national environmental quality of China in 2010 was stable compared with that of last year.
In general, surface water was under intermediate pollution; there was no large scale water bloom in major lakes and reservoirs. The quality of coastal marine waters had some degradation compared with that of last year, which was under slight pollution. Air quality of major cities on environmental protection was basically same as that of 2009. Acid rain pollution of China was still relatively heavy. The acoustic enterprise of functional areas of major cities kept stable with relatively heavy noise pollution during night. The surface water of typical rural areas was under intermediate pollution but with good air quality.
Environment monitoring results show that national surface water quality continued turning better; air quality of major cities on environmental protection improved year on year; eco environment quality kept stable and environmental quality of key river basins, regions and cities had evident improvement since the "11th Five-Year Plan" period. However, the pollution indicators of individual areas and region went beyond national standard with serious pollution. National environmental quality still has some gap compared with that of developed countries.
Increase of surface waters meeting Grade I～III national water quality standard
In 2010, 51.9% of the water sections under national monitoring program met Grade I～III quality standard, up by 3.7 percentage points compared with that of 2009 and 14.4 percentage points compared with that of 2005. 20.8% water sections failed to meet Grade Ⅴ standard, basically same as that of 2009 and dropped by 6.6 percentage points compared with that of 2005, which met the target (< 22%) specified in the 11th Five-Year National Plan for Environmental Protection.
The annual average of CODMn of water sections under national monitoring program had a downward trend year on year. In 2010, the annual average of permanganate value went down by 3.9% compared with that of 2009, down by 31.9% compared with that of 2005, which was superior to Grade III national surface water quality standard. The annual average concentration of ammonia nitrogen went beyond Grade III water quality standard, becoming an important factor affecting the quality of water environment. The concentrations of heavy metals such as lead and mercury of 40 water sections of such rivers as rivers in southwest China, Haihe River, Yangtze River and Yellow River went beyond the standards.
59.6% of the water sections in the seven big waters met Grade I～III standard, up by 2.3 percentage points compared with that of 2009, up by 18.6 percentage points compared with that of 2005, meeting the target (>43%) specified in the 11th Five-Year National Plan for Environmental Protection. Among seven big rivers, the mainstream of the Yangtze River had excellent water quality and its tributaries had good water quality. The Three Gorges Reservoir had excellent water quality. The mainstream of the Yellow River had excellent water quality and its tributaries were under heavy pollution. The mainstream of the Pearl River had good water quality and its tributaries excellent quality. The mainstream of the Songhua River was under slight pollution and its tributaries under intermediate pollution. The mainstream of the Huaihe River had excellent water quality and its tributaries were under intermediate pollution. The waters of the Haihe River were under heavy pollution. The mainstream of the Liaohe River was under slight pollution and its tributaries under intermediate pollution.
Among key lakes, the Taihu Lake was under heavy pollution and slight eutrophication. The comprehensive nutrition state index and concentration of TN and TP had some reduction compared with that of 2009. The frequency of water bloom went down in April～June and then went up during July～August compared with that of 2009. The Dianchi Lake was under both heavy pollution and heavy eutrophication, worse than that of 2009. It had regional water bloom during April～August. The Chaohu Lake was under intermediate pollution and belonged to slight eutrophication. Its water bloom during April～August was worse than that of 2009. The Hongze Lake was under intermediate pollution and belonged to slight eutrophication. The Dongting Lake was under heavy pollution and belonged to slight eutrophication. The Poyang Lake was under slight pollution and belonged to slight eutrophication. Dangjiangkou Reservoir enjoyed good water quality and belonged to mesotrophic status.
In 2010, among 39 trans-boundary rivers under monitoring, the water quality of in-flowing rivers was excellent while that of out-flowing rivers and trans-boundary rivers was under slight pollution. The main pollutant indicators are permanganate value, petroleum and BOD5. The Xingkai Lake across China and Russia was under slight pollution with TP as the main pollutant. The Lake Buir across China and Mongolia was under heavy pollution with COD, permanganate value and TN as main pollutants.
Some degradation of water quality of coastal waters
Coastal marine waters across China were under slight pollution in 2010, 62.7% of such waters met Grade I or II standard, down by 10.2 percentage points compared with that of 2009, down by 4.5 percentage points compared with that of 2005. 14.1% met Grade III standard and 23.2% met or failed to meet Grade IV standard. Main pollutants were organic nitrogen and active phosphates.
Among the four seas, the water quality of coastal waters of the Yellow Sea and South China Sea was good. The quality of coastal waters of the Bohai Sea was under intermediate pollution, the coastal waters of the East China Sea were under heavy pollution. Among the 9 important bays, the estuary of the Yellow River and Beibu Bay had excellent water quality. Jiaozhou Bay had slight pollution, Liaodong Bay had intermediate pollution. Bohai Bay, the estuary of Yangtze River, Hangzhou Bay, Minjiang River estuary and Zhujiang River estuary were under heavy pollution. Among 11 coastal provinces, over 80% of marine waters in Hainan, Guangxi and Shandong province met Grade I or II standard. Among them, 100% of marine waters in Hainan Province met Grade I or II standard.
Gradual increase of urban air quality
In 2010, the air quality of 73.5% of the major cities met Grade II national standard in terms of annual air pollutant concentration, up by 6.2 percentage points compared with that of 2009, up by 30.3 percentage points compared with that of 2005. There were 292 days in which the air quality of 95.6% major cities met Grade II national standards, up by 27.1 percentage points compared with that of 2005, meeting the target (>75%) specified in the 11th Five-Year National Plan for Environmental Protection.
In 2010, the annual average of SO2 concentration in the air of major cities went down by 2.3% compared with that of 2009; annual average of NO2 and inhalable particulate went up by 2.9% and 1.1% respectively. Compared with in 2005, the annual average concentrations of SO2 and particulate went down by 26.3% and 12.0% respectively, the annual average of NO2 was basically the same.
The overall air quality of Shanghai was good during the World Expo period, 98.4% of the days of the period met Grade II national air quality standard, up by 2.7 percentage points compared with that of 2009. The concentrations of SO2, NO2, and particulate met Grade II national standard, the lowest of the same period in the history.
The overall air quality in Guangzhou was good during the Asian Games, 100% days of the period met Grade II national air quality standard, up by 12.5 percentage points compared with that of 2009. The concentrations of SO2, NO2, and particulate met Grade II national standard. The air quality has evident improvement.
Acid rain pollution still relatively heavy
In 2010, the area subject to acid rain pollution (annual average pH <5.6) across China is about 1.2 million km2, accounting for about 12.6% of national land, same as that of 2009 and down by 1.3 percentage point compared with that of 2005. In general, the total area subject to acid rain pollution went down slightly. The areas with relatively heavy acid rain (annual average pH less than 5.0) and heavy acid rain (annual average pH less than 4.5) were basically stable. Acid rain mainly concentrated on the areas along and south to the Yangtze River, and eastern part to Qinghai—Tibet Plateau. There was no evident change of the distribution and types of acid rain across China. The main acid causing substances in precipitation is sulfate.
Urban noise kept stable
In 2010, the acoustic environment of functional areas of major cities on environmental protection kept stable. The meeting-noise-standard-rate of various kinds of functional areas was higher in daytime than in night. The meeting-noise-standard-rate of class III functional areas was higher than that of other types of function areas. About 62.7% monitoring sites of Class IV functional areas (areas along main trunk road) went beyond noise standard during night.
EI on rising trend
The overall eco environment quality of China was "general" during 2005~2009 with no evident change. The ecological index (EI) of China in 2009 went up by 0.5 compared with that of 2008 and 0.9 compared with that of 2005. In general, EI was on rising trend.
The overall rural air quality being good
Environmental monitoring was conducted in 274 villages from 31 provinces (autonomous regions and municipalities) in 2010 which adopted the "employing award to facilitate pollution treatment". The monitoring outcomes showed that the overall air quality was good; surface water was under intermediate pollution with E-coli, ammonia nitrogen and permanganate value as the main pollutants. 507 soil samples of six land use types from 27 provinces including cropland, vegetable plots, areas surrounding animal breeding farms, areas in vicinity of enterprises, farmland irrigated by waste water and areas in vicinity of landfill facilities were analyzed with going-beyond-standard rate at 11.1%～42.6%. The main pollutants included heavy metals and DDT etc.. The soil surrounding industrial enterprises and farmland soil were under relatively heavy pollution.
