Introduction
Scientists and specialists of different countries have
come to the conclusion that it is wrong to solve environmental problems in one
country. Developed countries differ from other ones due to the fact that they
use modern technologies in order to recover from air, water and soil pollution,
deforestation, littering and accumulate a lot of experience. However, these
countries are surrounded by poor neighbors unable to attack ecological problems
effectively.
Environmental pollution by fabric and domestic wastes
are actual all over the world. Furthermore, this issue is the most significant one
in the national action plan protecting Kazakhstan’s nature for stable
development of our country.
Todays situation in Kazakhstan demonstrates that
environment’s deterioration is dangerous not only for citizens’ wellbeing but
also for nation’s health. More than one
fourth of our country’s land are
inapplicable for living because of the nuclear tests on military firing fields,
million tonnes of toxic fabric wastes and soils poisoned by pesticides and
fertilizers. Due to the desertification more than a half of pasture land are
useless and 75% of irrigated land are saline. In some regions the level of
average life expectancy is reduced by 15-20 years in comparison with developed
countries like Japan, Germany, France.
Ecologists consider that there are more than 20
billion tonnes of solid industrial enterprises’ wastes in Kazakhstan. Only
non-ferrous metallurgy produced more than 5.2 billion tonnes of wastes.
Territories belonged to non-ferrous metallurgy plants occupy near 15000
hectares.
Every year this ‘bunch of garbage’ is increasing by 1
billion tonnes. The major part of toxic wastes are arranged in Zhezkazgan
region(29.4%), East Kazakhstan region(25.7%), Kostanay region(17%) and Pavlodar
region(14.6%). These regions are known for their industrial progress.
Main pollutants
It is not a secret for anyone that large congestion of
poisoning wastes are dangerous for the nature and humanity. They pollute air,
soil, rivers, lakes, seas and even groundwater. More than 25 years ago magazine
“ The UNESCO courier” characterized 8 main biosphere’s pollutants harming human
beings as well as flora and fauna:
1. Carbon dioxide
2. Carbon oxide
3. Sulfur dioxide
4. Nitrogen oxides
5. Phosphates
6. Mercury
7. Lead
8. Oil
«Hotspots» of Kazakhstan
Hotspots
are the most unfortunate places where people can hardly live. Usually, these
are located near places hostilities. Luckily, there is no war in Kazakhstan.
Nevertheless, there are some areas with polluted air, poisoned soils and toxic
water. Ecologists examined territory of our republic and named Kazakhtan’s
hotspots. They are lands located near industrial enterprises specialized on
copper mining such as joint-stock companies “Balkhashmed” and
“Zhezkazgancvetmed”. There can be found 8 piles of rocks and ores, 4 tailings
and 3 piles of dross where these companies put wastes of copper mining industry. Tailings keeping
especially dangerous substances are more dangerous for citizens and nature.
These objects not only pollute soil and flora, but they are also spread with
the help of wind on 10 km around.
There
are 14 plants specialized on the production of lead and zink. The most
dangerous are: “Achisay polymetallic plant”, “Zhezkent Mining Processing
Plant”, “Irtish polymetallic plant”, “Leninogorsk polymetallic plant”, “Tekeli
lead-zinc plant”, “Ust’-Kamenogorsk lead-zink plant”, “Shymkent lead plant”
,etc. These enterprises have more than 40 piles and 30 tailings.
Fabrics
situated near the river Irtish pollute water sources. For instance, “Zyryanovsk
lead plant” damage Bukhtarma reservoir. The bottom stream of pollution reached
the dam of hydropower plant Bukhtarma
and now dumps in Ust-Kamenogorsk reservoir which is known as fisheries pond. Of
course, it continues to pollute further Shul’ba reservoir till the boundary
with Omsk region of Russian Federation.
The
more region is anhydrous, the more pollution is dangerous. The minimal amount
of pollutants is required to seriously harm little rivers.
Besides,
factories specialized on mining and processing of rare metals and nickel damage
environment as well. “Belogorsk mining processing plant”, “Kairak mining
metallurgical plant”, “Ust’-Kamenogorsk titanium-magnesium plant” possess 10
piles as well as tailings dangerous for environment.
The most polluted air in Kazakhstan.
The
most damaged areas are Pavlodar, Karagandy, Zhezkazgan regions. The main air
pollutant is auto transport. As a
perfect example 1994 year might be considered. That year the total discharge of
cars was 1.2 million tonnes of fumes consisting of carbon oxide. As a matter of
fact, high concentrations of carbon monoxide disturb the balance in
atmosphere’s upper layers.
Water sources’ pollution.
The
most adverse situation is in Irtysh river basin where the level of polluting of
rivers like Glubochanka, Krasnoyarka, Breksy, Ul’ba, Bukhtarma by zink and
copper is quite high. What is more, the largest hot spots of groundwater are
located near the “Karagandy metallurgic
plant”, production association ”Karbid”, Aktobe CHP, “Himprom’s” slurry tanks
and settlers . The quality of water for drinking water-supply is rather low
especially in Kokshetau, Kizyl-orda and Kostanay regions.
Soil’s pollution.
Kazakhstan’s
land resources actively continue worsening: each year 250 000 hectares of
land become useless for agricultural industry. Soils are polluted with various
dangerous pesticides and poisonous toxic wastes. Industrial plants of
Ust’-Kamenogorsk, Zhezkazgan, Shymkent, Karagandy are responsible for this
terrible situation. There are lead, copper, zink and cadmium content in soil
reaches 10-50 MPC.
Non-peaceful atom.
The level of radiation in regions such as Semipalatinsk, Aktobe where
nuclear tests were held is still high. There is located a large amount of
uranium anomalies, occurrences and deposits.
Solid wastes.
One
more theme cannot but be mentioned is solid wastes. Every town and city faces
this problem daily. Due to the collapse of the communist system, abundance in
shops and markets appeared. So, the quantity of litter drastically increased.
Government in civilized countries are successfully solving the issue by
constructing lots of plants specialized on litter recycling. However, these
fabrics are not so popular in Kazakhstan. Therefore, each citizen in our country
produces 1.3-2.2 cubic meters every day. What is more, solid industrial wastes
are even more dangerous for land. East-Kazakhstan region is situated in the
central part of Eurasia. It is the most significant area in Kazakhstan
specialized on mining and metallurgical industry. Because of social-economic
development of this region, it is the most environmentally-unfriendly one. Lots
of sulphide polymetallic deposits
of Rudny Altay are sources of raw
materials for non-ferrous metallurgy , energy industry engineering and
construction industry. The composition of ores and scattered sulphide
mineralization metal deposits includes such metals as Cu, Zn, Fe, Mn, Ag, Ba,
Au, significant concentrations observed Cd, As, Sb, Tl, Hg, Se , and others .
In the oxidation zone of sulfide deposits in a humid climate the oxidation of
sulphides and removal of ore matter in groundwater environment. Oxidation of
sulfide minerals is followed by the temperature raising, formation of large
amounts of sulfuric acid. Aqueous solutions become acidic and high
aggressiveness. Mineralization of groundwater because of leaching ores and
surrounding rocks in the presence of large amounts of sulfate ion is increased
to 1 - 3 g / l or more , the water hardness increases to 15 - 20 mg -eq . / L ,
the concentration of ore-forming metals and their satellites is increased in
ten hundred times above background . The big danger for the environment and, above all ,
for water areas of deposits’ placing
and mining enterprises are pumped out of mines and quarries mine waters
, drainage and waste water tailings enrichment plants. The construction of
special treatment facilities is required for their disposal and treatment.
Conclusion
To
sum up, the quantity of wastes will dramatically rise until the progress in
fighting against pollution outweighs the industry. This is the reason why more
and more politicians are paying attention at environmental situation in
Kazakhstan by taking special measures such as reducing the amount of industrial
wastes. It is quite expensive for developing countries and their fabrics as
well as enterprises. Luckily, there are some methods encouraging individuals to
be environmentally-friendly like:
-
The adoption of national policy that recognize all waste
classification and aimed to help to implement it ;
-
Education about the waste problem
and the need to prevent the pollution, starting with primary school up to university programs for engineers and
managers;
-
Government’s financial support
directed to enterprises bringing up new projects to improve environment’s
safety;
-
High taxes on the production of
wastes;
