| | Vetiver grass for Ultrophication Control in Taihu Lake of China (Site not responding. Last check: 2007-10-01) |
 | | Taihu Lake, one of the largest lakes in China is located at around N31.20' and E120.16' with a total area of 2,420 sq. |
 | | The ultrophication led to high content of N, P, and C elements in the water and nearby soils and resulted in rapid growth of blue algae, green algae, etc. Consequently, the algae blooms occurred while the water transparency and soluble oxygen content was declined, leading to the death of many water organisms and aquatic life. |
 | | In the main lakes of Taihu Lake, such as Tai lake, Yiangcheng lake, Dshu lake, Jinji lake, Ge lake and Jiu lake, the mean annual inorganic nitrogen content in the water was more than 0.25 mg/L, which was 2.5 times of national parameter of surface water. |
