2. Description
The tragic toxic spill in January can
be considered
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
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,

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
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
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

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

Diversity: Wide diversity. The pollution affected several parts of the protected and
strictly protected National Parks in Hungary, such
as Lake Tisza, incorporated into Hortobágy
National Park (which is also an IBA area -Internationally Important Bird Area).
These have recently become part of the World Heritage program (1991), also
a Ramsar site (1979). Further areas
falling under the scope of the Ramsar Convention
(a treaty designed to preserve wetlands of international importance), and
biosphere reserves in the MAB (Man and the Biosphere) programme
of the UNESCO, are affected as well.The most affected
species were silver carp and spotted silver carp, which accounts for more
than 90% of collected dead fish.
In total, 64 species of fish were killed.

Effect: High and Product
23.
Urgency and Lifetime: High and 1-10
years.
The estimated rehabilitation for the
river is 1-2 years and for the riverbed is 10 years.
24. Substitutes: RECYCling. Differing processes for recovering gold without using
cyanide. Cyanide recovery or destruction systems are
available to mining companies, but these systems are not used
frequently at this time.
