I. Identification

1. The Issue

 

On January 30, 2000. a dam failure at the Aurul S.A. plant in Baia Mare (Romania) resulted in the biggest freshwater disaster in Central and Eastern Europe. Nearly 100,000 m3 of cyanide and heavy metal-contamined liquid spilled into the Lupus stream, reaching the Szamos, Tisza, and finally Danube rivers and killing hundreds of tonnes of fish and poisoning the drinking water of more than 2 million people in Hungary. Aurul S.A., which is owned by the Australian Esmeralda Exploration (55.2%) denied all responsibility.

2. Description

The tragic toxic spill in January can be considered Europe's worst ecological disaster since the Chernobyl nuclear reactor catastrophe in 1986. Cyanide, which spilled out of a gold mine in Baia Mare, eradicated aquatic life for miles in Europe's second longest waterway. The first official report from the General Manager of the Romanian Environmental Ministry, Liliana Mara, on January 31 reported cyanide levels 700 times above normal had been found in nearby river water after the spill. When the contaminated water reached Hungary, the cyanide levels (32.6 mg/l) were 300 times above the threshold of the Hungarian "highly polluted" standard. The transit of the cyanide spill through Hungary took a total of 12 days.

Warning to prevent human casualties

The amount of cyanide pollution in the River Tisza was equal to 60 million lethal doses for humans, therefore, Hungarian authorities ordered a disaster alert along the whole Tisza River. All water usage of the river was forbidden. For large settlements and urban areas, water treatment plants shut down until the danger had passed. Bottled water was shipped to the stricken areas to help overcome the ensuing water shortage. Thanks to this advanced warning, no human casualties were among the countless victims of the cyanide spill.

By the time the poisoned water reached the Serbian border on February 12, its concentration was less threatening, although dead fish were found in that part of the river as well. However, this accident had the most significant impact on the environment since it was neither the first, nor the last, case. In the past two years, Hungary has reported about a dozen incidents of water pollution from Romania. All of those disasters have had a deep impact on Hungary's economy and agriculture. International experts reported about $100 million in damages.

The "mourning"

People in Europe, but especially in Hungary were shocked by the environmental catastrophe. Unfortunately these kinds of "accidents" are not unusual and the consequences of this accident were the largest ever in Central and Eastern Europe. ''We use this river to fish and swim and now it's a danger in the middle of our towns. People are very emotional about it. We have never had anything like this.''-said a local man. When a person passes away in Hungary, relatives and friends throw flowers on the grave. This week it is the Tisza itself they have been mourning. A black flag had been raised at the city hall in Szeged (Hungarian city located along the river bank) where residents have held candle-lit vigils and dropped flowers off the bridges.

The polluter

The tragic poisoning was caused by breakage of the tailing lagoon's dam, which was maintained by the Australian-Romanian joint venture company, Aurul SA, in the region of Baia Mare in northwestern Romania Aurul S.A. is owned by the Australian Esmeralda Exploration (55.2%) and the Romanian Remin S.A. (44.8%) The project was co-financed by NM Rothschild & Sons Ltd. Australia and Dresdner Kleinwort Benson. Aurul reprocesses ore, which contains gold from the Remin mine in Baia Mare. This new company owns a modern factory for ore processing, which needed an investment of $30 million and produces yearly 1.2 tons of gold and 8 tons of silver. Cyanide is used to dissolve the gold and silver and separate it from the ore. Cyanide and heavy metal-ladened sludge is the waste product of this process. The waste is pumped through an above-ground pipeline over a distance of 15 km into a tailings lagoon. As the investigation concluded, the tailings dam failure resulted from an overflow of the pounding liquid, caused by: (1) inappropriately designed tailings dams; (2) inadequate monitoring of construction and operation of those dams; and (3) by severe, though not exceptional, weather conditions like heavy rain and melting snow. Nearly 100,000 m3 of water was polluted with high cyanide concentrations.

Ecological Impact

The cyanide spill first reached the Szamos, then the Tisza, and ultimately the Danube Rivers. The impacted area included 60 kms of the Szamos in Romania and 60 kms in Hungary, 550 kms of the Tisza in Hungary and 140 kms in Yugoslavia. In total, approximately 880 kms of river were severely polluted (This number does not include the pollution measured in the Danube). Potassium cyanide is a highly toxic crystal, the salt of hydrocyanic acid. It blocks the enzyme cytochromoxidase, inhibiting the supply of oxygen to cells. As cell respiration breaks down, organisms "suffocate from within." In addition to cyanide, the accident released sludge containing the heavy metals lead, zinc and copper into the environment. While cyanide toxicity is reduced over time, heavy metals are bioaccumulative and persistent. Because cold temperatures slow down the natural breakdown of cyanide into other less toxic compounds, the damages were even higher in this case as it was winter.

Fish are approximately one thousand times more sensitive to cyanide than humans, and the lethal poison killed hundreds of tonnes of fish in River Szamos and in Tisza up to a town called Tokaj. There was a significant damage below the Tokaj and in the Lake Tisza. Further down the river, the pollution was less, although it has been shown that the cyanide killed fish as far downstream as Yugoslavia. In total, 64 species of fish were killed (see partial list). Besides the immeasurable damage among fish species, which is the most visible sign of the disaster, cyanide pollution has eradicated all life, down to tiny organisms, throughout the rivers.

The disaster has resulted in the devastation of larger parts of planktonneic organisms of the rivers Tisza and Szamos. Perhaps equally significant is the huge amount of exterminated water fleas and insects that are an indispensable part of the food chain.

In addition, numerous water birds (bald eagles, cormorants, and blue herons) and mammals (deer, otter, and fox) were affected by eating contaminated fish and drinking water.

Moreover, the ground water resources for people along the river could become contaminated with heavy metals (in complex form; zinc concentrations, copper and silver were also detected) in the medium term.

Biologists are estimating that at least 5 years is needed to restockfish there, and 10-20 years for most of river life to return. In November 2001, the Tisza had been restocked at 18 locations with 2.5 tonnes of fish. The fish were tagged so experts will be able to evaluate the success of the resettlement.

The immediate economic impacts are the following:

1. Direct employment

Baia Mare is considered to be Romania's most polluted area with life expectancy ten years lower than country average, but also has a high rate of unemployment (15.4%). The largest segment of unemployed persons, at over 70%, are manual labors. After the accident, the unemployment of the Baia Mare area rose less than expected. Production of gold was suspended in Baia Mare, but Aurul kept all its employees. However, employment fell in industries that were dependent on products from Aurul S.A.

2. Fishing sector

The fishing sector in Hungary was the worst affected. Fishing is an important economic activity in the Hungarian part of the river. The damage had a serious impact on the fishermen's income and on the fish processing industries. In addition to the 1240 tonnes of fish stock killed by the pollution, a six month fishing ban was ordered in Hungary. Future damage prediction, along with the lower reproductive capacity of remaining fish stocks, is estimated to at least double from initial costs. The total damage in the fishing and angling sector was some US$ 5,839,000.

3. Tourism

The European mass media publicized the pollution continent-wide, leading to mass cancellation of already booked trips. This led to a reduction in both domestic and international tourism due to the river pollution. White water canoeing activity dramatically decreased by around 90% after the contamination events. This is due to the clear data that, instead of the usual 18-20,000 annual guests hosted in the Tisza region, only about 1,500 visited in 2000. Along the banks of the Lake Tisza, there was a 33% reduction in the number of German and Austrian tourists - the most striking and severe loss to the region’s tourism. These losses are particularly painful in a region that has very few operating enterprises and alternatives. Due to these facts, the damage to the Hungarian tourism sector was sizeable, due also to Hungary's significant dependence on tourism.

CASE MNEMONIC: Bolgold

CASE NAME: Bolivia Gold Mining

Bolivia, as many countries in Latin America, faces a trade-off between economic growth and protecting its environment. The South American country earns the majority of its foreign exchange from mining. Zinc is the main mineral exported, followed by tin, gold, and silver. Bolivia has liberalized its mining sector's investment regulations in an effort to increase its foreign capital. At the same time, the U.S. has made mining extremely difficult for its companies with more stringent rules. Gold has been an increasingly important export for Bolivia. However, U.S. and Bolivian environmental groups continue to fight mining exploration and operations, largely because of the devastating effects on the environment. Mining has led to soil erosion and the pollution of freshwater. Many Bolivian peasants feel torn, as these U.S. and foreign mining companies are bringing much needed jobs to their country.

CASE MNEMONIC: Bragold

CASE NAME: Brazil Gold Mining

Gold production has become a major source of income for several countries of the Amazon region, especially Brazil which has become the fourth largest producer in the world. The primary concern of the industry is mercury pollution that goes hand in hand with current mining techniques. Although the environmental effects of the mercury are not currently serious, there are significant dangers to the health of the human population of the region. Other factors involved in the case are human rights and the level of discretion that the Indians are entitled to in the use of the resources on their reservations. Finally, there is the sovereign right of Brazil to develop the Amazon as they wish. This is in direct opposition to the prevailing viewpoint of international environmental organizations, which regard the Amazon as a world resource.

CASE NAME: Gold Mining in Ghana

Caught in low literacy rates, high unemployment and foreign debt, Ghana is reliant upon its select few commodity sectors for revenue. Since the 16th century Ghana has been a world leader in the export for gold. Although increased levels of foreign direct investment have increased the overall output of the handful of major mines a 1989 law legalizing small-scale gold mining is leading to major environmental problems. Small-scale companies use outdated machinery and techniques and the situation is further compounded by lax government regulations and oversight

CASE MNEMONIC: Papua

CASE NAME: Mining in Papua New Guinea

During the 1980s, Papua ( New Guinea) experienced a proliferation of mining projects. With the third-largest gold reserves in the world, the country has become a magnet for giant multinationals seeking to exploit this rich resource along with extensive silver and copper deposits. However, the development of these mineral resources has been a mixed blessing. Toxic waste from the mines has polluted many areas of the country. Local residents, particularly those of the Bougainvillea region, have taken to armed resistance to protest the destruction of habitat and to express dissatisfaction with their lack of sharing in the mining benefits.

The Summitville Mine in southwestern Colorado is a Superfund site of the federal Environmental Protection Agency. The EPA took over supervision of the mine at the request of Colorado mining regulators after the most recent operator of the 1,400-acre gold and silver mine, Galactic Resources Ltd. of Canada, walked away from the site and filed for bankruptcy late in 1992, leaving behind acid mine drainage and a 160-million-gallon containment filled with cyanide-laden water that threatened to spill over the earthen berm holding it back.

CASE NAME: Venezuela Gold Mine

Gold miners in Venezuela are wreaking havoc on the Amazon rain forest, and its inhabitants, because of their destructive mining techniques. These miners are the same ones who were expelled for damaging the Amazon and the Yanomami Indian reservations in the Brazilian state of Roraima in 1990. The central government has been debating methods of enforcing tougher border controls, as well as tougher statutes on the export of gold from Venezuela, however, at present, the state is powerless to intervene.

 

CASE NUMBER: 314

CASE MNEMONIC: Zambcopp

CASE NAME: ZAMBIA AND THE COPPER INDUSTRY

Since the discovery of copper deposits in the 1920s in northern Rhodesia, which would become Zambia at independence, copper has had an "extraordinary dominance" (Bostock & Harvey, 1972) in the country's economy. Many developing countries depend heavily on a few primary products for export as their means of earning foreign exchange. Zambia, however, is an extreme case of over dependence on the production and export of a single product; copper. Zambia is also characterized by an urban community shaped by the requirements of the copper industry and the growth of its labor force. The dominating conflict points for this case are both trade related and environmentally focused. First, Zambia's dependence on copper has been exacerbated by its inability to influence world market prices, therefore negatively affecting its trading ability on the international scene. Second, Zambia's need to earn foreign exchange predominantly through copper, has over the years created environmental problems caused by the long and dangerous smelting processes of copper ore which heavily pollute the air and water sources. Under trade, the country's economy and therefore its development have been at the mercy of fluctuating world market prices dominated by the industrialized countries. Falling world prices have put Zambia's balance of trade into the red. Consequently Zambia is unable and rather reluctant to invest into tightening its pollution abatement and regulation standards. Environmentally, the most vulnerable to the pollution caused by the copper mining industry are the people located in the immediate vicinity of the mines, i.e. the miners and their families. However, if ever acid rain were to be produced by the gases from the copper smeltering process, land, vegetation, water sources and people hundreds of miles away could be affected.

The central banks in the developed countries reached the conclusion that the gold reserves could no longer support the national currency and let their national currency adjust. That is why they began to sell their gold, the most active countries in this direction are the United Kingdom and Switzerland. For an emerging market economy like that of Romania, the gold continues to be a stable support mechanism.. But it needed consolidation from the Canadian and Australian companies that brought investment in new equipment.
