Pollution and Human Impact Questions

Multiple choice chemistry man made materials plastic and environment pollution due to plastics environmental impact: plastics

Plastic is bad for environment because :

  1. they are non-biodegradable

  2. they harm aquatic life

  3. they are toxin carrier

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Plastic poses several environmental risks, including leaching chemicals and toxins into surrounding ecosystems, threatening the health of local animal populations and releasing greenhouse gases into the air. plastic are non-biodegradable. The negative effects of plastic vary depending on the type of plastic in the environment, quantity and length of exposure time. Plastics contain compounds, such as PVC and BPA, elements deemed a health risk to humans and animals while the leaching of these compounds into air and waterways poses a health and safety risk for nearby organisms.

Solid waste dumping sites or improper land fill sites face problems of ______.

  1. Air pollution

  2. Leaching

  3. Over fertilization of soil

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Introduction of an undesired component in the natural ecosystem is called as pollution. Water insoluble chemical that seeps inside the soil and gets mixed with ground water. Due to this ground water gets polluted.

Multiple choice

Plastic causes pollution because it does not

  1. Melt

  2. Biodegrade

  3. Change shape
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plastic is a synthetic material that does not break down naturally through biological processes, which is why it persists in the environment for centuries.

Organic pollutants are discharged as a municipal sewage and

  1. Industrial effluents

  2. Mining Pollution

  3. Natural pollution

  4. Artificial Pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Organic pollutants in water bodies typically originate from municipal sewage and industrial effluents, which contain high levels of organic matter that can lead to oxygen depletion.

  1. Air pollution

  2. Noise pollution

  3. Soil pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dumping of discarded particles of old furniture, utensils, glass pieces, ash, aluminium etc which are similar other products which do not get degraded and spoil the quality and profile of soil.

Nuclear waste is one of the sources of soil pollution.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When the wastes are disposed in the ground, there is leaching of the chemicals from the waste. This results in the soil pollution and contamination of the ground water. The oil and fuel, nuclear wastes and the coal ash are dumped by making pits in the ground. This results in the loss of the fertility and quality of the soil. So, nuclear waste is a source of soil pollution.

Which of the following is not a cause of soil pollution?

  1. Pesticide

  2. Dumping of pieces of old furniture and utensils

  3. Carbon monoxide

  4. Insecticide
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Carbon monoxide is a gas that primarily contributes to air pollution. Pesticides, insecticides, and solid waste (like furniture) are direct contaminants that accumulate in the soil.

Which of the following causes soil pollution?

  1. Oil spill

  2. Fertilizers

  3. Acid rain

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The following are the main mechanisms that generate soil pollution:
A. Antropogenic – through human activity including:
1. Accidental spills and leaks during storage, transport or use of chemicals (e.g., leaks and spills of gasoline and diesel at gas stations);
2. Foundry activities and manufacturing processes that involve furnaces or other processes resulting in possible dispersion of contaminants in environment;
3. Mining activities involving crushing and processing of raw materials (such as mining activity);
4. Construction activities
5. Agricultural activities involving the spread of herbicides/pesticides/insecticides and fertilizers;
6. Transportation activities (e.g., vehicle emissions)
7. Dumping of chemicals (accidental or intended – such as illegal dumping);
Storage of wastes in landfills (which may leak to groundwater or generate polluted vapours)
8. Cracked paint chips falling from building walls, especially lead-based paint;
B. Natural causes:
1. Natural accumulation of compounds in soil due to imbalances between atmospheric deposition and leaching away with precipitation water (e.g., concentration and accumulation of perchlorate in soils in arid environments).
2. Natural production in soil under certain environmental conditions (e.g., natural formation of perchlorate in soil in the presence of a chlorine source, metallic object and using the energy generated by a thunderstorm).
3. Leaks from sewer lines into subsurface (e.g., adding chlorine which could generate trihalometanes such as chloroform).

Which of the following is the source of soil pollution?

  1. Oil and fuel dumping

  2. Nuclear wastes

  3. Coal ash

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When the wastes are disposed of in the ground, there is leaching of the chemicals from the waste. This results in the soil pollution and contamination of the groundwater. The oil and fuel, nuclear wastes and the coal ash are dumped by making pits in the ground. This results in the loss of the fertility and quality of the soil. 

Thus, the correct answer is option D.

Soil pollution can cause 

  1. Soil infertility

  2. Land degradation

  3. Change is structure of soil

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil pollution leads to a variety of negative outcomes, including the loss of nutrients (infertility), physical erosion or contamination (degradation), and changes in the chemical and biological composition of the soil.

Which of the following is the industrial sources of soil pollution?

  1. Paints

  2. Cardboard

  3. Fertilizers

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Paint is any pigmented liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, colour, or provide texture to objects.
  • Soil pollution is defined as the presence of toxic chemicals (pollutants or contaminants) in soil, in high enough concentrations to pose a risk to human health and/or the ecosystem.
  • Paints consist of heavy metal pollutants which when mixed with soil causes soil pollution.
  • Hence Paint is the industrial sources of soil pollution.
  • So, the correct answer is 'Paints'.
