Pollution control Department is the agency that made the air quality. By measuring air pollutants include dust, small (less than 10 micron sized dust: PM-10). Sulphur dioxide (SO2), lead (Pb), carbon monoxide (CO), nitrogen dioxide (NOx), ozone (O3), and from nature.Source pollution caused by nature. Not caused by man-made pollution that has very little impact from the natural, for example,The eruption of the volcano, causing Smoke and ashes in the air a lot.The eruption of the volcano. Caused by the magma under the Earth's crust get heat from the pith, the world was cause of magma from a drainpipe of ejaculation's crust becomes lava.

Dust is characterized as small solid particles that float in the air, which caused objects that are bashing grinding bumps until split into small parts. When the wind blows, it will thukkrasae flyer in the air and the subsequent agreement to which time is fast or slow, depending on the weight of the dust particles. Sources of dust to represent the properties of the toxic dust with such as the radioactive hydrocarbons sabet stump lead dust, sat in a major air pollution problem in large cities and towns that are developing, it might lead to impact the health of people in both direct and indirect [7].
