As China’s pollution toll grows, protesters and media push back

By Fred Pearce - posted Tuesday, 30 March 2010


Days after the Dongling story made headlines, the authorities in Hunan in southern China shut a manganese smelter near Wugang, and detained two executives, after more than 1,000 people protested when 1,300 children fell ill - again from lead poisoning. Some were losing their hair, according to press reports. The plant had been open for only 15 months. Reporters from Xinhua discovered it had been operating without the approval of the local environmental protection bureau.

Then three smelters were shut in Jiyuan city in Henan, the world’s leading centre for the manufacture of the metals used in batteries. And in September, villagers blocked a major road in Fujian in eastern China. They were protesting the discovery that 121 children out of 287 tested in three communities were suffering from lead poisoning, apparently a result of pollution from the local battery factory. The factory, which only opened in 2006, suspended production.

In January, another battery factory, at Dafeng City in Jiangsu province, shut after 51 children became ill with lead poisoning. Again the factory had expanded without permission. Lead is not the only metal causing health problems. In another case that came to light in Hunan last fall, doctors diagnosed 509 inhabitants of Liuyang and Zhentou suffering from cadmium poisoning, which causes kidney and liver damage, and even cancer. Two residents had died before it was uncovered. Locals blamed the Changsha Xianghe plant, which opened in 2003 to manufacture zinc sulphate, an additive in animal feed.

The risks in Changsha were hardly unknown. In 2000, US authorities had banned zinc-based fertiliser imports from China after discovering they were contaminated with cadmium. But Xinhua reported that the Changsha factory had been heedlessly discharging industrial waste containing cadmium into watercourses that villagers used to irrigate their crops.

Metals like lead, cadmium, and zinc are also increasingly recognised as environmental and health threats in Chinese mining areas. In southern Guangdong, where rivers run orange and white with contamination, Chinese journalists have dubbed some communities “cancer villages”.

One facility under attack in 2009 was the state-owned Dabaoshan mine, which discharges acidic water laced with metals such as cadmium, killing most life in the Hengshi River, a major waterway in the area. Villagers near the mine drink and irrigate their rice crops with well water contaminated with cadmium and zinc. A 2009 study by Ping Zhuang, of the South China Botanical Garden at the Chinese Academy of Sciences in Guangzhou, confirmed dangerous levels of the metals in paddy soils and local food.

Adults suffer high rates of colon cancer. And Qing-Song Bao of the Department of Food Safe Supervision in Yixing reported that children downstream of the mine had high levels of lead, cadmium, and zinc in their bodies. He linked this to high rates of anxiety, depression, social problems, somatic complaints, difficulty concentrating, and delinquent and aggressive behaviour.

Faced with a crescendo of public concern, the central authorities in China two years ago launched a Pollution Source Census, demanding that the estimated 15,000 polluting factories, as well as mines and farms, come clean about their emissions, which often exceed formal license limits. The government insisted the aim was to evaluate rather than prosecute, and that legal action would only follow if companies continued the cover-up. The census results were published in February, revealing twice as much water pollution as previously recognised.

The pollution census may be lifting the lid on a story bigger than anyone has yet guessed. Last year a genetics professor at Nanjing University, Hu Yali, told journalists he believed environmental pollution was responsible for a tenth of all physical defects in Chinese infants. That was especially alarming since the vice-minister in charge of China’s National Population and Family Planning Commission, Jiang Fan, had warned that birth defects had risen by 40 per cent in China since 2001. She blamed emissions from mining and chemical industries and announced a new screening program for women contemplating pregnancy who lived in the eight provinces with the worst problems.

But while national authorities and media may push for reform and openness, local officials often quash protests and cover up even the worst pollution. Last summer, Chinese civil rights activists reported that Sun Xiaodi, an environmentalist in Gansu province, had been arrested along with his daughter and sent for “re-education” after exposing pollution problems at a uranium mine. Chinese law, at least in theory, protects whistleblowers who report environmental pollution. But the pair was charged instead with “providing state secrets overseas”.

And even in Chongqing, the local cliques appear to be back in charge. Local police have warned residents that there will be repercussions if they speak to the media. Some protesters have been accused of being members of the banned Falun Gong spiritual movement. Officials are even reported to have tried to discourage doctors from conducting tests for lead poisoning on new babies.

Late last month, the Dongling smelter announced that it will shortly reopen. One of the original protesters, Yang Tagu from the poisoned village of Sunjianantou, told reporters, “They want us to remain silent when the factory resumes production”. That may be so. But given the new-found activism of citizens and journalists, silence is in increasingly short supply in China today.
