What Are Primary Pollutants?

Primary pollutants are those substances directly emitted into the atmosphere that may cause harm to living organisms or upset the natural balance of nature. Examples of primary pollutants include carbon monoxide, sulfur oxides, dust, gases produced when burning fossil fuels and highly reactive organic compounds.

Primary pollutants normally affect the air directly and may cause death to animals, plants or human beings. They also cause other complications, including suffocation, skin irritation and global warming. It is important for every human being to be careful enough to avoid polluting the environment, in order to ensure a bright future for further generations.
