The problem is not only in China! Sick building syndrome and indoor air pollution still cause health problems in the US.
The Chinese are concerned. Are Americans even aware that there is a problem?
The China National Interior Decoration Association (CNIDA) sampled the air in several high-grade office buildings in Beijing last year, and it turned out 81 per cent of the locations exceeded the safety levels for ammonia, 50 per cent for ozone and 42 per cent for formaldehyde all hazardous elements known to cause illnesses such as Legionnaires' disease, asthma, hypersensitivity pneumonitis and humidifier fever.
In Shenzhen, Guangdong Province - the richest city in South China - the municipal centre for disease prevention and control did a similar test last year and found more than 90 per cent of the offices had excessive air pollutants.
The local environment monitoring station in Wuhan, capital of Central China's Hubei Province, tested 572 new and remodelled offices in the past four years. The result was that 89.8 per cent of them were overloaded with air pollutants, with some offices having 18 times more ammonia than the established maximum.
