Pollution Atmosferica Leading Causes

There are many causes of air pollution, but we can name some of the more common throughout the world, with its activities and emissions.

Refinery in oil
Activity: Refined petroleum and derivatives, such as fuels and lubricants substances manufacturing.
Emissions: carbon dioxide, methane, sulfur dioxide, hydrocarbons.
Effects: Cardiovascular and respiratory, eye irritation, carcinogenic properties, effect greenhouse and acid rain. Carbon dioxide, methane and oxides of nitrogen are important greenhouse gases. The oxides of nitrogen and sulphur are the cause of acid rain threatening all the forests of the Earth.

Chemical industry
Activity: Production of chemicals from various raw materials.
Emissions, sulfides, sulphur dioxide, carbon dioxide, organic and inorganic compounds.
Effects: carcinogenic properties and mutagenic, cardiovascular, respiratory and skin complaints, pestilence and different toxicities.

Incineration of waste
Activity: urban solid waste disposal
Emissions: sulphur oxide, various organic substances, hydrochloric acid.
Effects: cardiovascular, respiratory and central nervous system, carcinogenic properties and acid rain.
