Air pollution "Virtual Lab Chemistry Dobrianka TI
Mankind has entered the twentieth century under the slogan: Nature is not a temple but a workshop. This approach could not be completed global degradation of the environment great smog in the world. The current great smog ecological crisis is qualitatively different nature compared to all the previous ones. This is the first crisis that has engulfed the entire great smog planet is not entirely caused by natural great smog processes and human activities.
In 1992, in Rio de Janeiro hosted the conference of the UN (brought together representatives of 179 countries) Environment, which took the historic decision of the variable rate of the global society. The international community was concerned about the environmental situation in the world, is deteriorating. It analyzes the dynamics great smog of global catastrophe that could happen in the twentieth great smog century and lead to the death of all life on Earth.
The territory of Ukraine belongs to one of the most polluted in Europe due to the high production capacity great smog resources, outdated processes, significant business of development of low ecological culture of the population. Pollution boomerang struck great smog on health and life expectancy. Today, Ukraine is rapidly growing demographic crisis. Since 1993, the death rate exceeds the birth rate, 70% of children great smog are born with complications. The current environmental crisis, the result of human activity
Therefore, we, the Grade 11 students decided to investigate sources of pollution of air, water and soil, to find ways to improve the ecological great smog state of the environment, great smog to contribute to solving this problem. We live at the bottom of the great ocean-air atmosphere. A person can survive for weeks without food, days without water, but without air - a few minutes. Given that the day a person great smog consumes an average of about 1 kg of food and 2.5 liters of water and 12 kg of air is clear that clean air - the most important, the most important consumer product. Especially because breathing great smog has always - whether or not the polluted air and poisoned it or clean.
Today, the total capacity great smog of the sources of anthropogenic pollution in many cases exceed the natural capacity. Natural sources emit 30 million tons per year of nitrogen oxide and anthropogenic -35-50 million tons; sulfur dioxide, respectively, 30 million from natural sources and more than 150 million great smog tons of man-made. As a result of human activity and the biosphere lead gets 10 times more than in the natural contaminants. Among the settlements great smog of Ukraine the most polluted air of Dnepropetrovsk, Dneprodzerzhinska, Krivoy Rog, Donetsk, Mariupol, Zaporozhye, Lugansk, Alchevsk.
Smog is the cause of the destruction of the respiratory system; contributes to the development of lung cancer; ozone in small concentrations is a cause of chronic bronchitis, and in high - causing pulmonary edema. Acid rain have a harmful effect on the environment. The greenhouse effect is contributing to global warming on the earth. Such a sharp warming may cause the disappearance of some species of plants and animals. Some scientists believe that warming will cause melting of the Greenland ice sheet and Antarkdyty, which threatens an environmental disaster. Our group conducted a study on the sources of pollution in our village.
The beautiful and unique our village with their views. We live in an area where there is no industry that pollute the air we breathe relatively clean air. But in winter, more people began to use coal as a fuel is not, and rubber, as it is well lit and cheaper. But during its burning great smog a large amount of soot and smoke odor. If you continue to pass all of that type of fuel, the environmental condition of the atmosphere dramatically worse.
Pellets - Wood waste from wood processing production and chopped straw, sunflower husk and more. Calorific value of pellets at least 1.5 times greater than that of wood. So no wonder in Europe they are considered sustainable fuel for the future. And pesticides great smog degrade air that people use to cultivate gardens in summer, great smog especially from the Colorado potato beetle. Sometimes you can hear in the air, even the smell of Dostum, a substance great smog that has long been taken out of production, as a carcinogen.
We estimate that the average grain yield 30 quintals per hectare can be obtained 4,000 tons of straw. It can be recycled into pellets great smog and used for heating residential buildings villagers. This environmentally friendly fuel. With this proposal we have applied to individual farmers great smog and received a positive response.
Motor - the main pollutants nitrogen oxides (NO2) and carbon (CO). Engine exhaust gases contain more than 200 chemicals. The aim of our study: to show the benefits of switching to alternative transport fuels. For the study we selected great smog section of highway, highway Golden Beam - Novovoroncovka length of 250 m Determined number of cars, trucks, vans and buses. Did Bank
