Former top UK news photographer William Graham has been documenting the development of China’s financial hub Shanghai – where he now lives. The city is one of the fastest growing in the world – but at a price to locals.
Air quality was recorded at 303 on the official Air Quality Index (AQI) in early December, crossing the 300 threshold that indicates the most severe level of air pollution on the chart.
This is more than 10 times the daily guideline set by the World Health Organisation.
Today the city is home to more than 23.9 million people, compared to just 11 million in 1987. But pollution-related illnesses and conditions continue to be a threat to its residents.
