. Caused by human activities, transportation
2.1. The engine-driven vehicles such as cars, boats, aircraft, motor vehicle exhaust emissions, including significant off
.Oxides of nitrogen. Carbon dioxide
Carbon monoxide, sulfur dioxide, smoke, dust, moths and heavy metals
2.2. The industry. Industry is very important
.Emissions to air include industrial chemicals. Electricity industry.
Smelting industry.Metal refining industry. Cement industry. Food processing industry. Process to toxins such as smoke, dust, moths Acid Vapours
.The oxide of sulfur. Oxides of nitrogen. Of carbon dioxide from human activities in agriculture, etc.
2.3. Burning of agricultural waste injection
.The aerosol pesticides pesticides. Dust in the wind

2.4. Resulting from waste disposal. The city has no standards for waste disposal. Gas emissions of soot, dust or garbage incineration of solid waste is contaminated
.Into the air and dangerous
2.5. Caused by construction activities, building roads, transportation, backfilling and cement paint etc grinding dusts. Spray paint them with oil, such as gasoline, heavy metals
lacquer etc. etc.

From human activities.
2.1 transportation Caused by a vehicle that is driven by the engine, such as automobiles, aircraft, boats engines. Major pollutants from car exhaust pipes:
Nitrogen oxide Carbon dioxide. Monte carbon outer side
sulfur dioxide, smoke and dust, heavy metals, Mao
2.2. Arising from the factories Industrial plants are the most important source is
.Release toxins into the air, namely, chemical industry, electrical industry, tasa tasa tasa-karma to squander
.Metals, oil refining and tasa -Tasa tasa, cement and food processing industry in the process, they are toxic substances released, such as an acid smoke particulates Mao. Chemical vapor
Lead Assembly Sulfur oxide oxide of nitrogen oxide of carbon, etc.
2.3. Due to agricultural activities. Burning of agricultural remainder Injection
The eradication of pests, pesticide aerosol Floating dust by wind 2.4

Arising from waste disposal activities. The city where there are no standards to get rid of waste. Pollution from waste gases or dust Extractor, carbon burning waste will contaminate
.Into the air and dangerous.
2.5 Arising from construction activities. Building roads transportation The painted plaster filling mix To crush, etc, cause they color dust heavy metal evaporation of gasoline, oil, by Exchange of
, etc, etc.

. arising from activities of the human
2.1 transport vehicles from the car powered by an airplane engine such as motorboat สารมลพิษ out of the exhaust, car
Oxide of nitrogen dioxide carbon monoxide Sulfur dioxide condiments bed
smoke dust and heavy metals from Industrial Plants
2.2 is a very important source of
Let toxic substances into the air, including the chemical industry, electrical industry to spend
Metal industry oil refining industry cement industry food processing in production process will have toxic substances such as dust, smoke the condiments of the acid substances
contains lead Oxide of sulfur Oxide of nitrogen oxide of carbon, etc.
2.3 caused by agricultural activities on the remaining piece of burning agricultural sprayer the
pesticides to spray pesticides to dust floating in the wind

2.4 disposal of rubbish Activities The city is not a standard in the disposal of waste gas pollution from garbage heap of dust or smoke smoke burned rubbish will be contaminated
Go to the air, and it is dangerous.
2.5 caused by construction activities building where the road transport to cover the soil mixed Painted cement grinding, etc. , cause the color of spray cleaner with the heavy metal
oil volatile exchange such as benzene, burgers, etc. etc.
