According to a decade-long study by British and Hong Kong researchers, every 10 micrograms per cubic metre of increased exposure to tiny particulates in the air increases the risk of elderly Hongkongers dying from some kind of cancer by 22 per cent.
The study was conducted by University of Birmingham in the UK and the University of Hong Kong, which recruited over 66,000 people aged 65 or older between 1998 and 2001, and followed their mortality outcomes up to 2011.
Among the top ten killing cancers, there are five identified or associated in this report, inlcuding lung cancer, liver cancer, breast cancer, pancreas cancer, and upper digestive tract cancer.
The study highlights the importance of pulling Hong Kong’s air quality objectives closer to Who standards to safeguard public health.
