Environmental Issues NEET Questions with Answers

Environmental issues contain a range of problems that threaten the health of our planet and its ecosystems. These include deforestation, which leads to the loss of biodiversity and disruption of water cycles; air and water pollution, which contaminate natural resources and harm living organisms and climate change, driven by greenhouse gas emissions that result in global warming and extreme weather events. Each of these issues is interlinked, creating a complex web of challenges that affect not only wildlife but human health and livelihoods as well.

Addressing environmental issues requires a multifaceted approach, combining individual actions with policy changes and technological innovations. Sustainable practices, such as reducing waste, conserving energy and protecting natural habitats can mitigate some of the damage.

Environmental Issues NEET Questions with Answers

Q1. Which of the following is a secondary pollutant ?
NEET 2018
A) \( \mathrm{SO}_{2} \)
B) \( \mathrm{CO}_{2} \)
C) \( \mathrm{CO} \)
D) \( \mathrm{O}_{3} \)
Answer. D
Explanation: (d) Ozone \( \left(\mathrm{O}_{3}\right) \) is a secondary pollutant as it is formed by reaction amongst primary pollutants. On the other hand, \( \mathrm{SO}_{2} \) is a primary pollutant. These pollutants persist in the environment in the form they are passed into it. \( \mathrm{CO} \) is qualitative pollutant. It is considered as pollutant only when its concentration reaches beyond a threshold value in the environment.
\( \mathrm{CO}_{2} \) is a quantitative as well as a primary pollutant.
Q2. Fine organic or inorganic particles suspended in air is called
A) gaseous pollutant
B) particulate pollutant
C) aerosols
D) None of these
Answer. B
Q3. In plants, air pollution causes
A) reduce growth and yield
B) leads to premature death
C) Both (a) and (b)
D) None of the above
Answer. C
Q4. The harmful effects of the air pollution on organism depends on
A) size of bollutant particles present in air
B) concentration of air pollutants
C) duration of exposure and the organism
D) All of the above
Answer. D
Q5. Which method is used to remove particulate matter present in exhaust of thermal power plant ?
A) Wet scrubbers
B) Absorption
C) Electrostatic precipitator
D) Gravitational method
Answer. C
Explanation: (c) Electrostatic precipitator is used to remove particulate matter present in the exhaust of thermal power plant. These are very efficient devices, which remove \( 99 \% \) of particulates of 5-20 \(\mu \mathrm{m} \) size, present in the industrial and thermal plant exhausts.
Q6. The diagram given below shows electrostatic precipitator. Identify \( A, B, C, D \) and select the correct option.
A) A - Dust particle, B - Negatively charged wire, C - Discharge corona, D - Collection plate grounded
B) A - Discharge corona, B - Collection plate grounded, C - Dust particle, D - Negatively charged wire
C) A - Discharge corona, B - Negatively charged wire, C - Dust particle, D - Collection plate grounded
D) A - Discharge corona, B - Dust particle, C - Negatively charged wire, D - Collection plate grounded
Answer. C
Q7. \(\ldots\ldots\) are used in electrostatic precipitator.
Choose the most appropriate option to fill in the blank.
A) Catalysts
B) Absorbers
C) Electrodes
D) Chemicals
Answer. C
Q8. A scrubber in the exhaust of a chemical industrial plant removes
CBSE-AIPMT 2014
A) gases like sulphur dioxide
B) particulate matter of the size 5 micrometer or above
C) gases like ozone and methane
D) particulate matter of the size 2.5 micrometer or less
Answer. A
Explanation: (a) A scrubber in the exhaust of a chemical industrial plant removes gases like sulphur dioxide. The dirty air is cleaned by capturing the harmful gases in water/lime spray.
Q9. Which of the following health problems originate due to the inhalation of fine particulate matter ?
A) Irritation
B) Inflammation of respiratory tract
C) Damage of lungs and premature deaths
D) All of the above
Answer. D
Q10. The below diagram shows a scrubber. Identify \(A, B, C\) and \(D\).
A) A - Particulate matter, B - Clean air, C - Dirty air, D - Dust particle
B) A - Dirty air, B - Clean air, C - Water/lime spray, D - Particulate matter
C) A - Clean air, B - Dirty air, C - Particulate matter, D - Water/lime spray
D) A - Dust particle, B - Clean air, C - Particulate matter, D - Collection plate grounded
Answer. B
