What Is The Difference Between Primary And Secondary Pollutants Quizlet?

What are examples of primary and secondary pollutants?

Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide.

Secondary pollutants include ground-level ozone, acid rain and nutrient enrichment compounds..

What are the main sources of particulate matter?

Some are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles.

How are primary and secondary pollutants harmful for humans and environment?

Primary pollutants are directly generated from human activities like from car, from ships, from construction work etc. … Secondary pollutants form due to mixing of primary pollutants and natural resources such as water, air etc. They are harmful like mixing of sulphuric acid susoended in air with rain to form acid rain .

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 DDT a secondary pollutant?

It includes the DDT. The secondary pollutants are those which are not able to maintain their form in the environment. It includes the peroxyacyl nitrate which is formed due to the reaction between the primary pollutants like the hydrocarbons and nitrogen oxides. … It includes the DDT, fungicides etc.

What are the differences between primary pollutants and secondary pollutants give an example of each?

Examples of primary vs. Examples of primary pollutants include sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOX), and particulate matter (PM). Examples of secondary pollutants include photochemical oxidants (ozone, nitrogen dioxide, sulfur trioxide) and secondary particulate matter.

What are the sources of primary and secondary pollutants?

A primary source results from the direct emissions from an air pollution source. In contrast, a secondary source results from the formation of a pollutant in the atmosphere from the chemical reaction of precursors emitted from air pollution sources.

Which is more harmful primary or secondary pollutants?

2) Which are more harmful primary or secondary pollutants? Ans- They emit carbon monoxide which is one of the biggest contributors (by weight) to air pollution. Though these statistics are horrifying, secondary pollutants can be more harmful and severe to human health than primary pollutants.

Which among the following is a secondary pollutant?

Secondary pollutants are not emitted directly. They are formed from the combination of primary pollutants with some other compound. Examples of secondary pollutants are Ozone, Formaldehyde, PAN (peroxy acetyl nitrate) and Smog etc.

What is a secondary pollutant quizlet?

A secondary pollutant is when a primary pollutant comes into contact with other primary pollutants or with naturally occurring substances. An example is ground-level ozone.

What is the difference between primary and secondary sources of particulate matter?

Particle pollution can come from two different kinds of sources — primary or secondary. Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles.

What are the top 3 sources of particulate matter in the atmosphere?

Particulate matter (PM) is composed of solid and liquid particles in the air that are small enough to be inhaled. Natural sources of PM include sea salt, dust (such as airborne soil), and pollen, but it also includes material from volcanic eruptions and particles formed from natural gaseous precursors (eg sulphates).

What are 5 primary air pollutants?

5 Major Outdoor Air PollutantsOzone (O3)Nitrogen Oxides (NOx)Carbon Monoxide (CO)Sulfur Dioxide (SO2)Particulate Matter (PM10 and PM2.5)

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.

What are the three types of particle pollution?

Particulate matter is separated into three main groupings: coarse particles (PM10), fine dust (PM2. 5), and ultrafine dust (PM0. 1). These particle sizes, in general, differ in origin and health effects.

What are the 5 primary air pollutants and their sources?

Name five primary air pollutants, and give sources for each. The five primary air pollutants include carbon monoxide, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. The sources for all five of these pollutants include electricity production, industry, and transportation.

Is so2 a secondary pollutant?

Like nitrogen dioxide, sulfur dioxide can create secondary pollutants once released into the air. … Secondary pollutants formed with sulfur dioxide include sulfate aerosols, particulate matter, and acid rain.
