Question: Is Sulphur Dioxide A Primary Or Secondary Pollutant?

What is difference between primary and secondary pollutants?

Definition: A primary pollutant is an air pollutant emitted directly from a source.

A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere..

Is sulfur dioxide a primary or secondary pollutant?

Secondary pollutant form when primary pollutants emitted directly from a combustion process react in the atmosphere. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

Why is Sulphur dioxide considered a pollutant?

When sulfur dioxide combines with water and air, it forms sulfuric acid, which is the main component of acid rain. Acid rain can: cause deforestation. acidify waterways to the detriment of aquatic life.

Which is not a primary pollutant?

Explanation: Ozone is not a primary pollutant since it is formed by the photo-chemical reaction of oxygen with the UV rays and not directly discharged into the atmosphere by a source.

Is Pan a secondary pollutant?

PANs are secondary pollutants, which means they are not directly emitted as exhaust from power plants or internal combustion engines, but they are formed from other pollutants by chemical reactions in the atmosphere.

Is co2 a secondary pollutant?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds.

Does sulfur dioxide cause global warming?

Large volumes of SO2 erupted frequently appear to overdrive the oxidizing capacity of the atmosphere resulting in very rapid Warming. Such warming and associated acid rain becomes extreme when millions of cubic kilometers of basalt are erupted in much less than one million years.

Is Sulphur dioxide a primary pollutant?

Sulfur Dioxide – Air Pollutants of Primary Concern.

Which of the following is primary pollutant?

A primary pollutant is an air pollutant emitted directly from a source e.g., carbon monoxide (CO), oxides of nitrogen (NOx, NO), sulfur oxides (SOx), SO2, volatile organic compounds (VOCs) and particulate matter (dust, ash, salt particles).

Is benzene a primary or secondary pollutant?

Oxides of Carbon Then, we have primary pollutants such as Volatile Organic Compounds or VOCs which are methane (CH4) and non-methane (NMVOCs). Methane is a GHG which contributes to Global Warming. The NMVOCs include the aromatic compounds such as Benzene, Toluene, Xylene which are proved or suspected carcinogens.

What does sulfur dioxide do to your body?

Sulfur dioxide irritates the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO2 can cause inflammation and irritation of the respiratory system, especially during heavy physical activity.

Is Sulphur dioxide a pure substance?

Sulfur dioxide, (SO2), inorganic compound, a heavy, colourless, poisonous gas. …
