Another 90 kinds of non-antibiotic medical ingredients were also detected, according to the report released last week.
In some rivers, every liter of sample water was found to have several hundred nanograms of antibiotics, compared with less than 20 nanograms in water of developed countries.
The main sources of PPCPs are sewage plants, livestock waste water, pharmaceutical manufacturers, hospitals and cropland.
Official figures showed 70 percent of China's drugs are antibiotics, compared with 30 percent in Western countries.
Of all the antibiotics taken, only 20 percent is absorbed by humans. The rest is excreted and is a threat to nature, said Prof. Yu Feng with China Pharmaceutical University in Nanjing, capital of east China's Jiangsu Province.
At least 15,000 tonnes of drugs expire and end up in bins every year, said Prof. Yu. "The waste, if not treated properly, often contaminates surface water."
The wide use of antibiotics in the animal husbandry industry also worsens the risk of water and soil pollution, he said.
That's how you make super resistant killer bugs.
