Pollution rising in China’s problem river
The quality of water in the Huaihe river, one of the largest in China deteriorated in November, with only 57.8 percent of it considered safe for domestic, industrial or agricultural use, Xinhua said.
The figure is about 15.5 percent points less than last year, according to the environment surveillance center on the Huaihe River. The center carried out tests at 45 places along the river across Henan, Anhui, Jiangsu, Shandong and Hubei provinces, involving 20 indices including permanganate number index, ammonia and nitrogen content, the news agency said. ”
