The poor quality of the mainland's air has seldom been out of the headlines in recent weeks. But according to Elizabeth Economy, its water supply is equally problematic. In her blog at Asia Unbound she writes that, according to the Ministry of Water Resources, up to 40 per cent of the county's rivers were seriously polluted last year after 75 billion tonnes of sewage and waste water was discharged into them, while 20 per cent were rated too toxic to come into contact with.
Part of the explanation for this, she surmises, could be the 10,000 petrochemical plants along the Yangtze and 4,000 along the Yellow River.
The cost of all this in terms of human life is put at 60,000 premature deaths annually.
This is significant but some way below the 750,000 that die prematurely as a result of respiratory diseases related to air pollution, according to the Ministry of Environmental Protection.
