HONG KONG (REUTERS) - Chinese citizens are feverishly snapping up face masks as worsening air pollution fuels a multi-million dollar industry where many products fail to provide even basic protection, drawing calls for better oversight and standards.
The country's worsening air quality is at the top of the list of concerns of China's stability-obsessed leaders, anxious to douse potential unrest as a more affluent urban population turns against a growth-at-all-costs economic model that has poisoned much of the country's air, water and soil.
Authorities have invested billions in various projects to fight pollution, but none so far has solved the problems caused by cars, coal-burning power plants and outdated factories that spew millions of tons of toxins into the air.
It is estimated that air pollution in particular causes an estimated 350,000 to 500,000 premature deaths in China every year, according to an article in the medical journal "The Lancet" co-authored by China's former health minister, Chen Zhu.
Face masks have become the norm for many city residents, although only nine out of 37 types tested recently by the China Consumers Association met required standards in terms of filtering particulate matter and enabling easy breathing.
The most expensive, priced at 199 yuan (S$40.79), was no better than one of the cheapest, a disposable mask that costs 1 yuan, the association said in a report on the tests.
"The vast majority of face masks on the market give no protection against PM2.5, even if the manufacturers claim they do," said Lei Limin, vice chairman of the China Textile Commerce Association, referring to the small particulates that pose the greatest risk to human health because they easily pass into the lungs.
Mr Lei said his group is pushing for a national standard for anti-smog face masks, echoing calls last week by the China Consumers Association.
Face masks in China have traditionally been categorized as personal protective equipment mainly used for medical or industrial purposes. The country has no quality standards for face masks for personal use, despite the surge in demand.
Last year, consumers on the country's biggest online e-commerce site, Taobao, spent 870 million yuan on anti-smog goods like face masks and air purifiers.
Taobao, owned by Alibaba Group Holding Ltd IPO-ALIB.N, saw a 181 per cent increase in the number of people who bought face masks compared with the previous year.
"People are looking for anything that can really help them, that can help reduce any kind of health risk as a result of the pollution," said James Roy, an associate principal at Shanghai-based China Market Research Group.
