BEIJING (AFP) - Hospital admissions for respiratory complaints rose 20 per cent during the latest choking smog to hit Beijing, reports said Thursday as state media demanded greater government openness on pollution.
This week's pollution across vast swathes of northern China - the fourth serious case of toxic air in recent weeks - has sparked anger online and prompted unusually outspoken calls for action even from official media.
The number of patients admitted to several hospitals in the capital for breathing problems rose by a fifth in recent days, the Beijing Morning Post reported.
Half of those admitted to a children's hospital in the city were suffering from respiratory infections, the newspaper said, citing doctors.
The China Daily urged the government to reveal details of the causes of the pollution, saying departments had yet to provide "credible data".
Without such information "the government's promise to tackle the problem may fail to materialise", it said.
The pollution in the capital has been blamed on emissions from coal-burning in power stations and exhaust fumes from vehicles on choked streets.
The elderly, young and those with health problems in the city of 20 million were urged to stay indoors earlier in the week - or wear protective masks if they had to venture out - while dozens of flights were cancelled after visibility fell drastically.
Beijing has ordered the emergency closure of factories and removed government vehicles from the streets to try to reduce the haze, but experts say more radical controls are needed to combat the problem effectively.
Real estate tycoon and Internet blogger Pan Shiyi - who has 14 million followers on Sina Weibo, a Chinese version of Twitter - has started a campaign for clean air legislation.
It had attracted more than 46,000 signatures as of Thursday afternoon.
In a publicity stunt, another businessman has been pictured handing out cans of what he said was fresh air from China's regions to passers-by on the streets of the capital.
