Ninety percent decoration is still the most difficult to remove poisonous furniture after six months

Half a year after the renovation, 95% of the houses are still "toxic", of which 60% to 70% are caused by excessive harmful substances in furniture. The reporter learned yesterday from the first first general meeting of the Guangdong Indoor Environmental Sanitation Industry Association.

At present, the indoor environmental sanitation situation in Guangdong is worrying. Not only is the air quality in residential and private cars not optimistic, but the central air conditioning in many public places has become an invisible killer. It is also reported that Guangdong Province will develop industry technical standards and operating specifications for indoor air testing and evaluation.

Recently, Zheng Yongxu, general manager of the third-party special testing agency Guangzhou Saite Testing Company, told reporters, "According to the test, even after half a year of renovation, 95% of the residential hazardous substances exceeded the standard." He revealed that the air in family houses in Guangdong The poor quality is surprising. Among them, furniture is the largest source of pollution indoors. "Everyone has paid more attention to the environmental protection of decoration materials, but has neglected the release of harmful substances in furniture. In houses where harmful substances exceed the standards, 60% to 70% are caused by furniture."

"Some people think that if there is a pungent smell in the interior after the decoration, putting some green plants or air purifiers and other absorbent materials can solve the problem." Zheng Yongxu said that in fact these materials only absorb part of the smell that is emitted outside. The toxic substances in furniture or decoration materials have different release periods due to their different chemical properties. "For example, due to the failure of furniture stitching, if the released formaldehyde exceeds the standard, it will be difficult to eliminate even after ten or eight years." Zheng Yongxu believes that In addition to decoration pollution, indoor air in public places is more seriously caused by Legionella in central air conditioners.

He said that this is the "invisible killer" with a mortality rate of up to 15%, and the detection rate in the air-conditioning system in many public places is alarmingly high. "Guangzhou has tested central air conditioners in 33 public places such as hospitals, shopping malls, subways, and hotels, and 14 of them were positive for Legionella."
