The presence of the unsaturated zone below the surface of where the discharge is important. This is above the water surface area, in places down to the water to meet water-level. If the garbage underneath the unsaturated zone, the country operations as the is a filtering process by the chemical and biochemical activities.
Pollution of surface water:
Outer surface of the water near where the waste can get the toxic waste flowing from the surface. Moreover, the flow of land - the country also put chemicals into the water pollution. In terms of air exposure will promote decomposition of bio-chemistry of organic compounds. Evaporation at the surface is easier in the land.
Cross contamination by:
The organic compounds can evaporate into the air, the wind can bring toxic waste into the environment, fruits and vegetables grown close to where the waste can absorb the waste toxins.
The artificial air pollution is causing the most dangerous to humans and the earth's atmosphere?
The most dangerous man-made air for human health and the Earth's atmosphere has been known to include: carbon dioxide (CO2), sulfur dioxide (SO2).; Carbon monoxide (CO), nitrogen oxide (N2O); Clorofluorocacbon (also known as CFC) and methane (CH4).
1. Carbon dioxide (CO2) content of 0.03% CO2 with the atmosphere is the raw material for photosynthesis process to produce the primary biological productivity in the trees. Typically, the amount of CO2 produced naturally balanced with the amount of CO2 is used for photosynthesis. Two types of human activities that burn fossil fuels and deforestation have made the process imbalance, have negative impacts on global climate.
2. Sulphur dioxide (SO2): sulfur dioxide (SO2) is the air pollutant levels low in the atmosphere, mainly in the troposphere. Sulfur dioxide produced by volcanic eruptions, from burning coal, oil, gas, plant biomass, sulfide ores. Etc. .. SO2 is toxic to human health and animals, causes lung tracheobronchitis. SO2 in air to form oxygen and water have acid concentration in rain water causing acid rain.
3. Carbon monoxide (CO): CO is formed by burning fossil fuels do not all like coal, oil and some other organic materials. Emissions from the motorcycle engine is the source of CO pollution in major cities. Every year around the globe produce about 600 million tons of CO. CO is not toxic to plants because plants can transform CO => CO2 and use it during photosynthesis. Thus, vegetation is considered a natural agent is effective in reducing CO pollution. When people in the air is about 250 ppm CO concentration will die.
4. Nitrous oxide (N2O): N2O is a greenhouse gas glass, was born in the burning of fossil fuels. Its content is growing on a global scale, every year approximately 0.2 - 3%. Small amounts of other N2O into the atmosphere as a result of nitrification of organic fertilizers and inorganic. N2O into the atmosphere will not change the format in the long run, only reaching the upper atmosphere of the new impact it slowly with oxygen atoms.
5. Clorofluorocacbon (abbreviated as CFC): CFC are chemicals synthesized by humans for use in many industries and from there into the atmosphere. CFC 11 or CFCl3 or CFCl2 or CF2Cl2 (also known as Freon 12 or F12) is the common nature of the CFC. A small amount of other CFCs CHC1F2 (or F22), CCl4 and CF4 also enters the atmosphere. Both compounds CFC 11 and CFC 12 or freon are compounds of high economic significance, the production and use has increased rapidly in the past two decades. They exist both in the form of aerosols and aerosol. Aerosol form is often damage the ozone layer, so that the alarm about the environment, these types of aerosols are not produced and continue growing in number. CFCs are highly stable and not decomposed. When CFCs reach the upper tanphan cancel. Speed will decompose quickly if CFC ozone damage and ultraviolet radiation to reach the lower atmosphere.
6. Methane (CH4): Methane is a greenhouse gas. It was born from the biological process, as the men of the intestinal tract of animals with hooves, sheep and other animals, the resolution in anaerobic wetlands, rice paddies, forest fires and combustion of agar. CH4 oxidation promotes the stratospheric water vapor. The increase in water vapor causes the greenhouse effect stronger than the direct effect of CH4.
Currently the atmosphere annually received about 400 to 765x1012g CH4
