Air Pollution:

Air pollution can be defined as an alteration of air quality that can be characterized by measurements of chemical, biological or physical pollutants in the air. Therefore, air pollution means the undesirable presence of impurities or the abnormal rise in the proportion of some constituents of the atmosphere. It can be classified in 2 sections: visible and invisible air pollution.

Types of Pollutants:

In order to understand the causes of Air pollution, several divisions can be made.

Primarily air pollutants can be caused by primary sources or secondary sources. The pollutants that are a direct result of the process can be called primary pollutants. A classic example of a primary pollutant would be the sulfur-dioxide emitted from factories

Secondary pollutants are the ones that are caused by the intermingling and reactions of primary pollutants. Smog created by the interactions of several primary pollutants is known to be as a secondary pollutant.

How is Air Quality Measured?

With measuring devices using laser-based technologies, chemiluminescence, flame ionization, etc. These devices are, for instance, located close to the traffic, far from the traffic and close to industrial zones. All the collected data are compiled into a value scale, called the Air Quality Index (AQI).

Causes of Air Pollution:

-The burning of fossil fuels

-Agricultural activities

-Exhaust from factories and industries

-Indoor air pollution

-Mining operations

Effects of Air Pollution:

-Effect on Human Health:

-Mortality

-Cardiovascular Disease

-Lung Disease

-Effect on Central nervous system

-Effect on wildlife

-Agricultural effects

-Global Warming

-Effect on Environment

-Depletion of the ozone layer

-Eutrophication

Air Pollution Prevention:

There are ways to prevent, control and eventually reduce air pollution:

-Renewable fuel and emphasis on clean energy production

-Energy conservation and efficiency

-Eco-friendly transportation

-Use public mode of transportation

-Green building

-Understand the concept of Reduce, Reuse and Recycle

Look around, walk around, breathe clean air and don't litter the ground. :) :)
