Public panic

Zhang, a pregnant woman from Hanzhong, Northwest China's Shaanxi Province was uneasy when she moved into a recently decorated apartment with her husband in October. She was worried about indoor air pollution, even though they had put supposedly toxin-absorbing charcoal bags in their house, bought green plants and opened their windows often.

She asked for advice on an online parenting community, and to her surprise, nearly all the 46 comments suggested she move out of the house for the sake of the baby. Two parents were even convinced that their friends' kids had caught leukemia from living in newly decorated houses.

Zhang's worries are common. In 2006, the country's first lawsuit over excessive formaldehyde emissions aroused nationwide concern and boosted public awareness of indoor pollution. Mawei district court in Fuzhou, East China's Fujian Province, sentenced a decoration company and a panel maker to pay a couple 170,000 yuan ($24,470) in compensation for their role in the death of the couple's daughter, who was diagnosed with leukemia after living in a newly decorated house for a year. Air quality tests showed that the levels of formaldehyde in the house's air was 0.39 mg per cubic meter, nearly five times the national standard for home air quality.

In recent years, indoor air pollution-related diseases have been reported more and more, especially those related to formaldehyde, which can irritate the skin, eyes, nose, and throat. High levels of exposure may cause some types of cancers.

In 2004, the International Agency for Research on Cancer reclassified formaldehyde from "probably carcinogenic to humans" to "carcinogenic to humans" based on increased risks of cancer of the upper throat.

In China, it is often connected to leukemia, with some medical workers finding evidence of this link.

After a five-year survey of 570 acute lymphocytic leukemia child patients and 1,000 healthy minors, Fang Yongjun, chief hematology physician at Nanjing Children's Hospital, and his team found a connection between home renovation and developing the disease. They claim to have shown that moving into a house within the six months following its decoration will increase a child's risk of getting the disease 4.76 times, according to a 2012 report by xhby.net, a news portal based in Jiangsu Province.

Zhang's mind was not set at ease until her husband spent tens of thousands of yuan on air conditioners and an air purifier which all claim they can help eliminate formaldehyde.

Hazards hyped?

However, Song's testing center found that the air purifiers' formaldehyde removal function is ineffective after testing 10 products including seven foreign brands.

"Their anti-formaldehyde function was exaggerated, and the severity of indoor pollution was somehow magnified," he said.

At a summit on infants' health held in Guangzhou, South China's Guangdong Province on December 13, Zhong Nanshan, a well-known respiratory physician clarified that indoor air pollution has become a major killer.

He said that "lavish home improvement is found in 90 percent of leukemia child victims' houses; 2.1 million children die from lavish renovation annually; 70 percent of miscarriages are linked to environmental pollution," the Guangzhou Daily reported.

However, Zhong made a public apology nine days later, saying it was improper to quote the unverified figure of 2.1 million child deaths.

According to the Database of Death Surveillance in China 2014 released by Chinese CDC and National Health and Family Planning Commission, the total number of deaths of children from all causes between 0 and 14 in 2014 was only 130,000.

The 2.1 million figure was first reported by China News Service in 2003 which quoted a child health expert. Since then, it has been widely quoted in reports and articles. No related authorities or individuals have ever made any public corrections.

Song, vice director of the China National Interior Decoration Association, said these misinterpretations and overstatements circulating on the Internet have misguided people and intensified public panic.

"Some enterprises make use of false information or hype the risks to promote their anti-formaldehyde products," he stated.

The market is filled with products to check or wipe out formaldehyde. Some professional companies also offer door-to-door services to help with the problem.

"Years ago, the issue of indoor carcinogenic benzene pollution was very serious. But after decade-long efforts to supplant this kind of paint with water-based paint, the pollution is almost controlled," Song said, explaining that the government increased taxes on solvent paints which carry benzene.

To help consumers spot zero-formaldehyde decorating products, the authorities have set up a special QR code for them. Despite the technological barriers, Song said industry regulators have pledged to control formaldehyde in home decoration products within 10 to 15 years 图片6.png
