Nearly 100 million people have been supplied with drinking water containing unsafe levels of toxic chemicals.
A team from Tsinghua University has observed the levels of per- and polyfluoroalkyls (PFAS) that are man-made chemicals used in fabrics and pesticides, by using data from previous studies, reported South China Morning Post (SCMP).
The study found that the concentration of PFAS in more than 20 per cent of the studied Chinese cities exceeded safe levels.
Since China has no national safety standards, the study used the US state of Vermont’s regulations as the benchmark.
The cities with high levels included Wuxi, Hangzhou and Suzhou in eastern China and Foshan in the southern province of Guangdong, according to SCMP.
