pollution

Pollution or environmental pollution is the introduction of living things, energy substances, and / or other components into the environment, or changing the order of the environment by human activity or by natural processes so that environmental quality decreases to a certain level which causes the environment to be less or not work again in accordance with its allocation (Act No. Principles of Environmental Management. 4 / 1982).
Substance or substances that can cause pollution called pollutants. The terms of a substance called a pollutant when its presence can cause harm to living beings. Contohnya, karbon dioksida dengan kadar 0,033% di udara berfaedah bagi tumbuhan, tetapi bila lebih tinggi dari 0,033% dapat rnemberikan efek merusak. For example, carbon dioxide content of 0.033% in air beneficial to the plant, but when higher than 0.033% to yield to the damaging effects.
A substance can be called a pollutant if:

1. 1. amount exceeds the amount in excess ofnormal normal2. 2. located on the not is at times notAppropriate right3. 3. be in a place not be in a place notAppropriate right
The nature of pollutants are:1. 1. damage for a while, but when it reacts with the substance of damage for a while, but it reacts with substances Plsenvironment does not damage the longer notes damage the environment more
2. damaging in the long term. 2. Damaging in the long term.For example if the lead did not damage the low concentration. For example if the lead did not damage the low concentration. But Butin the long term, lead can accumulate in the body in the long term, lead cans accumulate in the bodyto the extent that destroy. That to the extent destroy.
Types of PollutionVarious kinds of pollution can be distinguished based on place of occurrence, pencemarnya kinds of materials, and pollution levels. Various Kinds of pollution cans be distinguished based on place of occurrence, pencemarnya Kinds of materials, and pollution levels.
a. According to the site ofAccording to the place of occurrence, pollution can be classified into three, namely air pollution, water, and soil. According to the place of occurrence, pollution cans be classified into three, namely water pollution, water, and soil.
1. Air Pollution Air PollutionAir pollutant gases and particles can form. Air Pollutant gases and particles cans form. Examples are as follows. Examples are as follows.a. HzS gas. a. HzS gas. This gas is poisonous, there are volcanoes in the region, This gas is poisonous, there are Volcanoes in the region,can also be generated from burning oil and coal. Also cans be generated from burning oil and coal.
b. CO gas and Coz. Carbon monoxide (CO) is colorless and not Carbon monoxide (CO) is colorless and does notodorless, toxic, is a hash that is not burning odorless, toxic, is a hash That Is not burningperfect from car exhaust and engine material letup. Coz in a perfect gas from car exhaust and engine material letup. Gas coz in.pure air amounted to 0.03%. pure water amounted to 0.03%. When you exceed the tolerance to her When you exceed the tolerance cans Eitherinterfere with breathing. interfere with breathing. In addition, the C02 gas is too much at In Addition, the C02 gas is too excessive inearth to the sun's heat so that bind to heat the earth's temperature. earth to the sun's heat so That Bind to heat the earth's temperature.Global warming of the earth due to C02 is also known as the Global greenhouse warming of the earth due to C02 is Also known as greenhouseglass. glass.
c. SOZ particles and NO2. Both these particles together with liquid particles Both these particles together with particles of liquidforming dew, forming clouds forming near the ground which can be dew, clouds forming near the ground the which cansinterfere with breathing. interfere with breathing. Solid particles, such as bacteria, fungi, solid particles, Such as bacteria, fungi,virus, feathers, and pollen can also interfere with health. virus, feathers, and pollen cans Also interfere with health.
d. coal containing sulfur through the burning going toproduce sulfur dioxide. Produce sulfur dioxide. Sulfur dioxide was $ ama with air and sulfur dioxide was $ ama with water andoxygen and sunlight can produce sulfuric acid. Produce oxygen and sunlight cans sulfuric acid. This acid These acidsform a mist and a time will fall as rain which forms a mist and a time will of fall as raincalled acid rain. Called acid rain. Acid rain can cause interference on May cause acid rainhumans, animals, and plants. Humans, animals, and plants. For example, respiratory problems, For example, respiratory disorders,morphological changes on leaves, stems, and seeds. morphological changes on leaves, stems, and seeds.
Another source of water pollution cans come from radiation of radioactive materials, for example, nuclear. After a nuclear detonation, the radioactive material into the atmosphere and fall on earth. Explosion After a nuclear, radioactive materials into the atmosphere and fall on earth. this radioactive material will terakumulusi in soil, water, animals, plants, and also in humans. terakumulusi will from this radioactive material in soil, water, animals, plants, and Also in Humans. Nuclear pollution effects on living beings, in some degree, can cause mutations, a variety of diseases caused by gene abnormalities, and even death. Nuclear pollution effects on living Beings, in Some degree, can cause mutations, a variety of diseases the caused by gene abnormalities, and even death.
Water pollution expressed by ppm (parts per million), the which means the number of cm3 per m3 of water pollutants.
