Are primary pollutants more harmful?
Primary pollutants ans secondary pollutants are equally harmful. Secondary pollutants are more harmful than primary pollutants.
Are secondary air pollutants more harmful?
Primary pollutants and secondary pollutants can be more dangerous. The first are those that are emitted directly from a source, which can be natural (volcanic eruptions or fires, for example) or of anthropogenic origin (carbon monoxide from vehicles). Secondary pollutants, on the other hand, are not emitted directly.
Which of the following is the most harmful pollutant?
Sulphur dioxide is the most harmful pollutant. It is responsible for acid rain. Sulphur dioxide produces smog. It causes membrane damage, destruction of chlorophyll, corrodes metals, impairs sensitive equipments, damages buildings, marble, paper and textiles.
How do secondary pollutants harm the environment?
Harmful Secondary Pollutants Primary pollution is harmful enough, but when it mixes with the atmosphere, it creates damaging secondary pollutants like smog and nitrogen dioxide. These secondary pollutants can affect other areas too by creating acid rain.
How does a primary pollutant differ from a secondary pollutant give an example of each?
A primary pollutant is emitted directly into the atmosphere and a secondary pollutant is produced from reactions within atmospheric substances. An example of a primary pollutant is carbon monoxide. An example of a secondary pollutant would be Tropospheric ozone.
What is the difference between primary and secondary air pollutants What are some examples of each?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What is the main reason we need to distinguish between primary and secondary pollutants?
Identifying air pollutants and studying the difference between primary and secondary pollutants are important for the control and prevention of atmospheric pollution, especially through the reduction of anthropogenic sources.
What is most harmful to the environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Which one of the following pollutant is more harmful for the health of humans Mcq?
Particulate matter (PM) It affects more people than any other pollutant.
What is the main difference between primary air pollutants and secondary air pollutant?
| Primary Pollutants | Secondary Pollutants |
|---|---|
| These are radiated from the source itself | These are produced by the chemical reaction between primary pollutants and the elements of the atmosphere. |
| In the atmosphere, these are found in the original state. | These are not found in the original state. |
What is the difference between primary and secondary pollutants quizlet?
What is the difference between primary and secondary pollutants? Primary pollutants are harmful substances emitted directly into the air. Secondary pollutants are formed when primary pollutants react with one another or with the basic components of air to form new harmful pollutants.
What is the difference between primary and secondary air?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What are the differences between primary pollutants and secondary pollutants give examples of each?
Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollutants: Pollutants that are formed in the lower atmosphere by chemical reactions.
What are the harmful substance that pollute the environment?
They can be gases, like hydrogen chloride, benzene or toluene, dioxin, or compounds like asbestos, or elements such as cadmium, mercury, and chromium. The U.S. Environmental Protection Agency has classified 187 pollutants as hazardous.
What are the harmful materials which pollute the environment?
Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides—chemical poisons used to kill weeds and insects—seep into waterways and harm wildlife.
Which causes most harm to human health Mcq?
Which one of the following cause harm to human health? Explanation: Pesticides can harm to human health if they use in excess proportion in the environment. Pesticides are intentionally toxic substances linked to various diseases like cancer, birth defects, mutations and other health problems.
How is CO and CO2 harmful to humans?
Carbon dioxide acts as a simple asphyxiant; in other words, as CO2 levels in a closed room rise, carbon dioxide replaces the oxygen your body needs. When your body can't get oxygen, it slows down and does not function properly. Because carbon dioxide is an asphyxiant, it mostly affects your brain.
What is the difference between a primary and secondary air pollutant?
Glossary: Primary & Secondary pollutant. 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 is the most damaging type of pollution?
Most dangerous air pollutant – particulate matter This group of air pollutants refers to solid particles that appear as a result of mixing the droplets present in the air with soot, dust, and mineral elements. It can have a natural origin – for example, wildfires or volcanic eruptions.
Which one of the following causes harm to human health?
Which one of the following cause harm to human health? Explanation: Pesticides can harm to human health if they use in excess proportion in the environment. Pesticides are intentionally toxic substances linked to various diseases like cancer, birth defects, mutations and other health problems.
Why is CO2 gas harmful?
Carbon dioxide acts as a simple asphyxiant; in other words, as CO2 levels in a closed room rise, carbon dioxide replaces the oxygen your body needs. When your body can't get oxygen, it slows down and does not function properly. Because carbon dioxide is an asphyxiant, it mostly affects your brain.
What’s the difference between carbon monoxide and carbon dioxide?
The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom. Carbon dioxide is non-flammable, whilst carbon monoxide is not – we certainly wouldn't encourage you to light a match in order to determine which gas is which.
Where are air pollution problems the most severe?

What is the difference between primary air and secondary air quizlet?
Primary are emitted directly into the air from a specific source while secondary are not emitted directly from a source but are formed in the atmosphere.
Which pollutants are proved to be more harmful to humans?
Ultrafine Particles (UFPs) UFPs are the most dangerous particulate matter because their tiny size makes them extremely inhalable.
Which pollutant is more hazardous to human lunch than others?
While all pollutants in the atmosphere cause harm to the planet, there are some that are more dangerous than others. The more dangerous air pollutants are: Sulphur Dioxide – high concentrations can result in breathing impairment for asthmatics that are active outdoors.
Which one of the following is a negative effect of environmental pollution for human health?
Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts.
