The cyanide pollution of the rivers
in szamos and Tisza was caused by AVRAL, an Australian joint venue in the
Romania’s Baia Mare region.
In the year 2000 a dam failure
occurred in the biggest fresh water disaster in central Europe. Nearly 100,000
metres cubed of cyanide and heavy mental liquid spilled into the stream reaching into
Szamos killing hundreds of animals in the Dubai Rivers and poisoning the
drinking water.
The tragic toxic spill in 2000 was
considered the worst ecological disaster.
The amount of cyanide pollution in
the river Tisza was equal to 60 million lethal doses for humans and alerts were
authorised along the whole Tisza River.
People in Europe were shocked by the
environmental catastrophe these types of ‘accidents’ were unusual for this
country.
Over 11 days 500 samples were taken from about 30 different sample sites after the spillage.

A description of Szamos-Tisza Cyanide Pollution

-Effected central and Eastern Europe

- Cyanide pollution extracts metals from waste rock from mining areas which uses metal enrichment technologies and then is carried out after the waste ore has been grounded.

-The cyanide spill fits reached the Szamos and then immediately to the Danube Rivers.

Lithosphere, Biosphere, Hydrosphere and Atmosphere

- The spilage polluted water way.

- The polluted water soaks into soil into lithosphere affecting how energy will travel and affect the growth of plants and animals.

- Biosphere being affected when the living organisms drink the water and die as the consotration of cyanide was over 60 times the amount for recomanded human drinking.

- The pollution from the Szamos-Tisza also affected the entire aquatic ecosystems.

-The most common forms of pollution in the hydrosphere are the waste products from humans and industries.

-Green house gases are being released into the atmosphere from air pollution

- Air pollution can create acidic compounds which can cause harm to vegetation (crops)

Question 1 a

The cyanide pollution of the rivers Szamos and Tisza was

caused by AURAL, an Australian-Romanian point venture that is situated in
Romania’s Baia mare region. The cyanide in these areas was used to extract left
over metals from waste rock around the mine region. This process requires lots
of water which is why the mines are placed next two water ways including the
Zazar and Lapos which belong to the catchment area of the Szamos River. An
extraordinary event to place 10pm on the 30^th of January 2000 where
100 thousand mega litres of wastewater with a high concentration of cyanide was
discharged into the water ways leading to Szamos River. Another event occurred later
close to the first incident, however it was less serious to the first event.
This then exceeded the water ways percentage limit of cyanide by sixty. It then
flowed into nearing towns flooding them in orange cyanide water. Killing crops
and destroying homes and destroying the water source.

Affecting spheres

Although the Cyanide pollution doesn't seem like a big problem it influences life on Earth. The Szamos-Tisza Cyanide Pollution problem is affecting biosphere when the water intoxicates birds, mammals by oral inhalation in the vicinity of height cyanide concentrations. The issue is also currently affecting the hydrosphere when the cyanide pollution pollutes the water and then it travels through multiple water ways in the oceans also causing harm to sea creatures. The Biosphere is impacted by this event because when the water is polluted, it kills the fish which is effecting there prey and the rest of the aquatic food cycle. There are numerous examples of extremely high conditions of concentraction of oil, gases and nutrients which are not connected with human activity at all but are still effected from the problem of cyanide pollution. One main important part of the Cyanide pollution which is a sub effect is that the existence of marine creatures could be increased after the problem has been resolved which may increase levels of enclosed seas and coastal waters as compared with the open ocean.

The star is the river

The event happened in .......

jjurc3 — 2015-05-25 04:42:51 UTC

- Zazar and Lápos waterways that belong to the catchment area of the Szamos River.

- it happened in the location close to the first one

- fortunately, it was more serious then the previous event

-The event took place at 10.p.m on the 30th of Janurary 2000

How many organisms where effected in the event?

jjurc3 — 2015-05-27 00:40:25 UTC

Considering that both cyanide and metal complexes of cyanide cause direct acute toxicity in living organisms getting in contact with them, it is important to have thorough knowledge of the toxic effects of these substances on certain groups of living organisms and on their habitats. It also helps to determine the degree of damage in different groups of living organisms.

The toxic effect of the lowest concentrations of cyanides can be detected in the case of fishes, zooplanktons and benthic organisms. The toxic effect on the phytoplanktons (algae) is caused by 4-6 times higher concentrations than in case of the fishes, while in the case of certain benthic organisms this concentration is even higher. The issue of accumulation of pollutants in the living organisms and especially in fishes should also be taken into account.

Beyond the individuals of aquatic organisms other ecosystems having contact with the aquatic environment (birds, mammals, macro vegetation etc.) can also be damaged.
