The village of Dong Mai in Vietnam’s agricultural heartland had a serious problem.

To boost their meager incomes, its residents – former artisans who once produced and sold bronze casts – had taken to cannibalizing old car and truck lead-acid batteries and smelting them by hand in their own backyards. As a result, the 2,600 people living there had some of the highest blood lead levels ever recorded."Concretely: We know how to change the situation because we have done it." -- Stephan Robinson

Dong Mai’s water and soil had become terribly contaminated — 32-36 times higher than the acceptable limits. People were getting sick, including children. One home assessed with an X-ray Florescence (XRF) analyser had lead levels 50 times the higher than the U.S. Environmental Protection Agency (EPA) standard.

Local government knew of the problem, but the cost of cleaning it up – expected to run into the millions – was daunting. Then, a collaboration with the Blacksmith Institute for a Pure Earth found ways to remediate the lead for much less: about 20 dollars a person.

Once major remedial work was completed, in February 2014, lead levels in the population fell by nearly a third in six months.

“Political will takes time to build,” Rich Fuller, Blacksmith’s president, told IPS. “Governments need solid data on the scope of problems, and how to solve them. Most governments are just starting to build their teams for pollution, and those NGOs that provide support, rather than criticism, have really been a huge help.”

Together with Green Cross Switzerland and the Global Alliance on Health and Pollution (GAHP), the Blacksmith Institute released a report Tuesday highlighting cleanup success stories like Dong Mai’s.

Top Ten Countries Turning the Corner on Toxic Pollution notes that pollution kills more than 8.9 million people around the world each year, most of them children, and the vast majority — 8.4 million — in low- and middle-income countries.

To put that figure in perspective, it is 35 percent more than tobacco-related deaths, almost three times more deaths than malaria and 14 times more deaths than HIV/AIDS.

“Contrary to popular belief, many of the worst pollution problems are not caused by multinational companies but by poorly regulated small-scale operations like artisanal mining, small industrial estates or abandoned factories,” Stephan Robinson of Green Cross Switzerland told IPS.

“However, high-income countries are indirectly contributing by their demand for commodities and consumer goods to the issue as many of these small-scale operations produce the raw or precursor products,” he added. “They thus support many of these smaller industries, adding to the severity of pollution problems in low-income countries.”

Lead, the culprit in Dong Mai, is especially devastating for children. It can damage the brain and nervous system, cause developmental delays, and in cases of extreme exposure, result in death. Children also tend to have higher exposures because they play in dirt and put their hands and other objects in their mouths.

The economic toll of pollutants on poor and middle income countries is high: the costs of air pollution alone range between six and 12 percent of GDP.

Previous Blacksmith reports had focused on the 10 worst toxic hotspots, but this year, the groups chose to look at practical, replicable solutions that don’t require a vast amount of resources to implement.

“There is so much to do,” Fuller said. “Only a few countries have started down the path. We wanted to give them credit, and have them be examples for expanding work on pollution in other countries.”

In the case of Dong Mai, mobilising the active participation of villagers and local officials was key.

Instead of removing the contamined soil and carting it off to landfills, the backyards were capped with sand, a layer of geotextiles, 20 centimetres of compacted clean soil, bricks, and finally, concrete on top, safely sealing away the lead.

After an educational campaign, 50 villagers took on the task of remediating their own yards in this way. What could have cost about 10 million dollars was accomplished for 60,000.

“GAHP members are encouraged to help their neighbours,” Fuller said. “Often, a success in one country can translate into a project in another.  This is certainly true of lead poisoning and e-waste. The GAHP model is collaborative between international agencies, and between countries, all helping each other work out how to solve these awful problems.”

The other success stories in the report were led by Ghana, Senegal, Peru, Uruguay, Mexico, Indonesia, Philippines, the Former Soviet Union and Kyrgyzstan.

In Thiaroye Sur Mer, Senegal, lead battery recycling was replaced with profitable hydroponic gardens.

In Mexico City, a contaminated oil refinery was turned into an urban park with one million visitors a year.

In Agbogbloshie, Ghana, informal e-waste recycling by burning electronic scrap that released toxins is now performed safely by machines.

“We worked hard to find solutions that would work for the local recyclers,” Kira Traore, Blacksmith’s programme director for Africa, says in the report. “Simply banning burning wouldn’t help them earn an income. Rather, forbidding burning in Agbogbloshie might push the practice elsewhere, thus expanding the pollution and the number of people affected by it.”

Experts note that local sources of pollution – particularly heavy metals like mercury and arsenic – are often very mobile and can have health impacts thousands of kilometres away.

“Mercury from unsafe artisanal gold mining and coal plants travels the globe and is found in our fish which, e.g., we eat as sushi in London,” Robinson said. “DDT (dichlorodiphenyltrichloroethane) is found in the body fat of the inhabitants of Greenland, though there was never agriculture in Greenland.

“Contaminated air from China and elsewhere can be measured in other countries. Radionuclides from nuclear disasters, like Chernobyl, have reached other countries in most of Europe,” he noted.

In essence, rich countries have not only a moral obligation but a vested interest in helping poorer nations address pollution.

“Western nations have had success in cleaning up their toxic and legacy pollution over the last 40 years and can transfer technology and know-how to low- and middle-income countries today. Concretely: We know how to change the situation because we have done it,” he said.

“Pollution problems can only be solved by organisations joining forces and bringing in what they are best at…These are stories proving we are on the right track, and moving forward. But we need to do more with industrialisation in full swing around the world.”

Parts of Indonesia, Argentina and Nigeria are among the top 10 most polluted places on the planet, according to a new report by U.S. and European environmental groups.

They are extraordinarily toxic places where lifespans are short and disease runs rampant among millions of people who live and work at these sites, often to provide the products used in richer countries.

“People would be shocked to see the conditions under which their lovely jewelry is sometimes made,” said Jack Caravanos, director of research at the New York-based Blacksmith Institute, an independent environmental group that released the list Monday in partnership with Green Cross Switzerland.

In Kalimantan, Indonesia, local people extract gold using mercury, which is both poisonous and a potent neurotoxin.

“They do this processing inside their homes, not realising the danger,” said Bret Ericson, senior project director of the Blacksmith Institute.

Blacksmith has gone into those homes and measured mercury levels 350 times higher than what is considered safe, Ericson told IPS.

This directly affects the health of 10 to 15 million people, Ericson said. “It is also a huge source of mercury pollution worldwide.”

Once released into the environment, mercury can end up in fish and other foods people eat anywhere on the planet. Low-cost, mercury-free methods for gold mining do exist but this knowledge is not widespread, he said.

The Top Ten Toxic Threats report is the latest in a series of annual reports documenting global pollution issues. The list is based on the severity of the health risk and the number of people exposed.

Previous reports have documented that the disease burden of pollution is comparable in scope to tuberculosis or malaria, posing a threat to 200 million people. Globally, one-fifth of cancers and 33 percent of disease in children can be blamed on environmental exposures, but this is far higher in low income countries, the report notes.

The Blacksmith Institute has conducted more than 3,000 initial risk assessments in 49 countries since the last list of polluted sites released by the two groups in 2007. Some sites listed in 2007, such as the lead battery recycling site in Haina, Dominican Republic, have been fully remediated.

“The good news is countries like India have come to grips with their pollution problems,” said Ericson. India has imposed a “Clean Energy Cess” or coal tax to help fund a clean energy fund of up to 400 million dollars which will inventory and clean up contaminated areas.

However, one of the emerging issues around toxic hotspots are clusters of poorly-regulated small-scale industries now found in many countries. There are more than 2,000 industries along the Citarum River in Indonesia, contaminating an area 13,000 sq km in size with lead, mercury, arsenic and other toxins, the report found.

“Clean-up is beginning thanks to a 500-million-dollar loan from the World Bank, but it will take a decade or more to complete,” said Ericson.

Near Buenos Aires, Argentina an estimated 50,000 small-scale industries dump a toxic mix of chemicals and metals into the air, soil and water. At least 20,000 people living along the Matanza Riachuelo river are exposed to dangerous levels of toxins, the report shows. The World Bank is also funding a major clean-up, with Blacksmith providing technical support.

Some toxic hotspots are so big and so badly polluted it will cost billions of dollars and take decades to clean up, said Stephan Robinson of Green Cross Switzerland.

“There are places that will be on our list for many years,” Robinson told IPS.

Russia has two of these. Russian authorities have finally acknowledged the issue and set aside three billion dollars to clean up Soviet-area legacy sites. One of these is Dzerzhinsk, a city of 300,000 people where chemical weapons like sarin, VX gas, mustard gas, and phosgene were manufactured for 50 years. At least 300,000 tonnes of waste from their manufacture were disposed of in the groundwater.

Birth defects are very common and the average lifespan of residents has fallen to the low forties. The situation is similar in Siberia’s Norilsk region, where the world’s biggest nickel smelter has killed all the trees within a 30-km radius.

“There has been lots of talk about improving pollution controls in Norilsk but not much action,” said Robinson.

A new site that will be on the list for years is the very polluted Niger Delta in Nigeria. Millions of barrels of oil have been spilled over the years and a U.N. study found two-thirds of the sites tested to be highly contaminated. Petroleum and its byproducts are very toxic, and when combined with poor nutrition, are a major unrecognised health threat for the 30 million people who live there, the report noted. The U.S. has been the major export destination for Nigerian oil.
