Rice harvest in October 2013, Renhua County in Shaoguan city Dong town farmers found that the danxia smelting plant beside 3500 acre rice seeds germination and far more serious rice production. Smelting enterprises of villagers suspected of being caused by pollution. Involving thousands of local farmers ' livelihoods and food rations, Renhua County Government has emergency coordination to address the matter at the end of last year.
Recently, the only identification of qualifications issued by Guangdong province reported smelter excessive arsenic, mercury and lead in soils of rice. Mercury supra-national limit values of pollutants in food 1250%, lead over 1345%, "rice is not fit for human consumption, rice is not suitable for seed germination rate is low". Rice flowering stage under the influence of atmospheric sulphur dioxide damage caused by severe, causing rice production. Smelter said, factories discharged sulfur dioxide.
In 2012, the excessive toxic heavy metals in children's blood has been seen on the ground.

The drain
Beginning of December 2013, hundreds of acres of farmland near the danxia smelting plant is not harvested. Wang Yue long lease of plots was shixing, seed production, and he's got a hundred acre field evidence of contamination: yellowing of the leaf, husk is black and empty, empty ear pointed to the sky, there is no harvest at all heavy.
It turns out that 2012 Renhua Dong town after occurrence of toxic heavy metals exceeded in the children's blood, Renhua County multilateral consultations decided danxia smelting plant around 3500 acres of land classified as agricultural land to sublet. Centrally by the town and danxia Dong Tong Street from farmer, to 800 Yuan/Mu tenancy subcontracted to foreign growers. Danxia smelting plant of 800 yuan per Mu to assume 305 Yuan per MU, foreign growers pay 500 yuan per MU. Renhua County introduction of seed enterprises, planting rice seeds. County Government believes that rice seed no secondary pollution, while addressing the problem of contaminated land cultivation, increase local farmers ' income.
Take this opportunity, Wang Yue in the seed industry for 31 years far into 3500 acres of heavy metals in the soil. On June 4, 2013 danxia Street in Wang Yue long dong in the local town, entering into a tenancy agreement, 3500 acres of land next to the contracted danxia smelting plant, while contracting in fankou lead-zinc mine near the more than 2,600 acres of land for rice seed production.
In October, more than 6,000 acres of seed paddy to start harvesting. Danxia smelting plant near 3500 acres of farmland, produce low levels of final germination percentage of rice seeds, simply do not meet state requirements, and 3 kilometres more than 2,600 acres of farmland in fankou lead-zinc mine production of germination of normal.
Improved varieties of Guangdong Co Ltd letter confirmed that rice seeds germination rate is low, fall short of contractual 85% indicator, also fall short of the targets set by the State 80%.
"Analysis, the smelters around the seed germination percentage of farmland is only 40%-65%. Far below the national standard. "Wang Yue long said, normally an acre of land can produce 160 kilograms of seeds, wholesale price under the contract, 20 Yuan/kg, 3200 Yuan per Mu value. 3500 acres of farmland output could reach 11 million Yuan.
"After the contamination, yield dropped to 96.5 kg/MU, germination percentage does not meet national requirements, seeds can turn poor-quality commercial food processing total only points more than 660,000 yuan. "Wang Yue long said.
Renhua County high village, 51 villages near the smelter village farmers grow rice in a wide range of cuts, many villagers point to land beside the danxia smelting plant emissions. High village village party branch secretaries in November 2013 an interview Paul Yip said that most of the village more than 400 acres of rice fields were affected, most of the production of more than 20%, some serious 40% is possible.
On May 20, 2014, head of Guangzhou Municipal Association for science and technology issued by the Guangzhou science and technology consulting Center, 3500 Mu production and seed germination in soil evaluation report, the Centre is the only company in Guangdong Province has polluted causality identification of eligible units.
Appraisal reports that refineries of heavy metals in paddy soils in harvested over seriously. At 0.63 mg/kg arsenic, contrast in the latest national standards for the maximum levels of contaminants in food grain is 0.50 mg/kg arsenic, arsenic 3500 acres of farmland paddy Super GB 26%; client 0.27 mg/kg of mercury content of rice, representing national standard exceeding 0.02 mg/kg of 1250%. Over top of all that lead, rice tested 2.89 mg/kg of lead, national standard of 0.2 mg/kg, the local ordinary value of 0.87 mg/kg, representing GB Ultra 1345%, hyper-local value of 232%.
"Rice production in the region is not good for eating, not suitable for seed. "The report says.

Poisoning inference
Why rice production and seed germination is not high? Reports issued by the Guangzhou science and technology consulting Center "from rice plants suffer symptoms that appear, in line with the rice plant caused by sulfur dioxide acute effects symptoms result and, in addition, large area of paddy rice shell, rice is not full, might be regarded as rice flowering stage seriously affected by damage caused by sulfur dioxide, resulting in rice production."
Renhua high village, 51 villagers and Wang Yue further confirms the report, villagers say, danxia smelter ' sulphuric acid plant North backer, South is farmland, once a North wind, will affect thousands of acres of farmland near. 2012 farmer over more than 100 acres of farmland burnt, receipt of food is also a problem, Tong Tung Renhua danxia town in town, many of the villagers raised dissatisfaction. 2013 smelters around the farm continued under the influence of strong-smelling gas emissions at the plant, resulting in poisoning in rice.
"In 2012, I actually have used land near danxia smelting plant rice, danxia smelting plant smell of fog affect flowering in rice, rice finally yielded no fruit. "Wang Yue long said.
Rice experts, Guizhou agricultural college told yangcheng evening news reporter He Junyu, an associate professor at the University, if in suitable conditions for germination of seed is not good, this is due to the vigor of the seed embryo is not high, new vitality and the germination of the seed embryo when the full extent of environmental conditions, seeds, nutrients and toxins in the seed content.
"High and low content of harmful substances in the seeds and soil environment has a direct relationship. According to the description given, seed and I think it might be related to high levels of heavy metals and organic pollutants. "He Junyu recommends selecting soil samples and samples of rice seed in the region, quality inspection departments to Guangdong province for further analysis, so you can determine what caused the cause of difference in seed germination of seed in the region.
Rice in Hunan Zhang Yuzhu, Deputy Director of the Institute researchers believe that smelting waste gas there is a certain influence on rice growth and germination percentage is not high but this event whether mature or maturing stage and seed of climate-related needs further evaluation.
Information obtained from Renhua County show, Renhua area in fankou lead-zinc-rich ore, mercury mine, rendering the soil acidity. And the ground more than 50 years of mining and smelting of lead and zinc mine, no environmental protection measures worsened soil contamination by heavy metals, Renhua danxia smelting plant in fankou lead-zinc mine, only around 31,800 hectares of land contaminated with heavy metals.
"Our factory is certainly a little sulfur dioxide, but sulfur dioxide is discharged. "Danxia smelting plant official says. Emissions were accepted by the local environmental protection Bureau, and upload the data. "(Production and seed question) appears around not only in our factory, (around) a lot of things. Sulfur dioxide drift off to a few kilometers should we plant, where a dozen miles away. ”
Factories, seed germination rate is low for many reasons. In addition to factory, local environment itself has a lot of problems, and growers need to evaluate the suitability of soil cultivation and seed production of rice.
"We had no basis is impossible to compensate, companies are not in my family. I home I make concessions would do it. State-owned enterprises I can't do right now. "Replies danxia smelting plant Wang Yue and the local farmers.

Money for pollution treatment
Reporters learned from Renhua County Government, 51, high around 2013 danxia smelting plant at the end of early rice and late rice planting in the vicinity of the village with varying degrees of production, the masses react very strongly. To ensure normal production of fankou, danxia smelting plant, to tackle food security, the County recommends danxia smelting plant in fankou mine, expand the scope of peripheral conversion of farmland leasing. Now 3500 land extended to the surrounding 20,000 acres of land. Specific leases ranging from Mr Tung town, in fankou lead-zinc mine, danxia smelting plant, Renhua County agricultural extension Centre jointly decided.
November 2, 2013 Renhua County Government to danxia smelting plant supervisor company sent a letter says: "may be subject to local danxia smelting plant dust impacts, the land produced seed germination rate of just 50%, 2014 had been raised on the farm tenancy, and sought compensation from the rule of Dan give a certain loss, land leasing prospects require considerable assistance in the future, and work together on these issues. ”
Renhua County Board report to the provincial people's Congress research group, said the local soil polluted by heavy metals, in addition to the high end of things, industrial pollution is important. Part of the production process of discharged wastes containing heavy metals lead, cadmium, mercury, while the enterprise produces a lot of coal slag landfill to the soil, and finally, businesses waste water without treatment into the soil pollution.
"Soil not Guangdong Shaoguan heavy metals exceeded the maximum number of, at most, position number 5-6, Shaoguan is the soil heavy metal pollution in most areas, gravity most of the province. "Guangdong Institute of eco-environmental and soil researcher Wan Hongfu described earlier told deputies to the national people's Congress of Guangdong Province. Shaoguan is the hometown of non-ferrous metals, accumulation of polluted industrial development for many years. Heavy acid rain areas of Shaoguan in Guangdong, Guangdong provincial environmental protection Bureau on heavy acid rain for several years, "black list".
But local governments money treating soil heavy metal pollution-free. 2012 Renhua County to raise $ 6 million for town of heavy metal pollution in Tung's 50 acre ecological rehabilitation pilot, to 120,000 yuan per MU on average, treatment costs the equivalent of 240 years planting rice returns to that land, or gains of 47 kinds of seeds, soil pollution control cost is huge.
Renhua County Party Secretary Liu Feng to the investigation of heavy metal pollution in soils of Guangdong provincial people's Congress leader said that the County is poor, 450 million a year, finances can only protect the local basic meals, no heavy metal contamination in soil.
