Questions Related to pollution due to plastics

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

______ is an example of biodegradable .

  1. Thermal power plants

  2. Fertilizer industries

  3. Steel plants

  4. Cotton mills
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cotton mills  (cotton clothes) is an example of biodegradable.
Other biodegradable materials are paper, wood, peels of vegetable and fruits, leftover foodstuff, woollen clothes etc.
Non-biodegradable materials are plastic bags, tin, aluminium, and other metal cans.

Note : Biodegradable waste consists of plant and animal waste that is broken down by other living organism. It is produced in industries like cotton mills, food processing units, paper mills and textile factories.

A Correct answer
Explanation

Biodegradable waste consists of plant and animal waste that is broken down by other living organism, substances that are broken down by biological processes are said to be biodegradable. Biodegradable waste products can also be called green waste, food waste, or organic waste.

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

Burning of plastic causes :

  1. water pollution

  2. air pollution

  3. sound pollution

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

Plastics is burnt which releases toxic gases like Dioxins, Furans, Mercury and Polychlorinated Biphenyls into the atmosphere. Further, burning of Poly Vinyl Chloride liberates hazardous halogens and pollutes the air, the impact of which is climate change. The toxic substances thus released are posing a threat to vegetation, human and animal health and environment as a whole. These gases cause air pollution only.

 Disposable plastic plates should not be used because:

  1. They are made of materials with light weight

  2. They are made of toxic materials

  3. They are made of biodegradable materials

  4. They are made of non-biodegradable materials
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Disposable plastic plates should not be used because its waste is non-biodegradable and cannot be broken down into its base compounds by micro-organisms, air, moisture or soil in a reasonable amount of time. Non-biodegradable waste is an environmental concern, as it threatens to overwhelm landfills and create disposal problems.

Hence, the correct option is $D$

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

Non-biodegradable substance releases harmful gases when burnt.

  1. True

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

Non-biodegradable products include plastic products, metal products, construction waste, electronics etc. Non-biodegradable products are items that cannot decay or be broken down by living organisms. The bio-degradable substances leach out toxic chemicals when they are burnt and are harmful to health.

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

The substance which undergoes decomposition by the microbial action is called a:

  1. biodegradable substance

  2. non-biodegradable substance

  3. recyclable substance

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biodegradable substances are those materials or products that are able to naturally break down or decompose without causing any harm to the environment. Biodegradable substances are generally things that are organic in nature. This means they are substances that are made from things that were living at some point. Examples of biodegradable substances include paper which is made from trees, meat products which come from animals and leather products.

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

Environmental pollution by plastics can be minimized by practising the 4R principle of:

  1. REDUCE, REUSE, RECYCLE

  2. REDUCE, REUSE, RECYCLE and RECOVER

  3. REDUCE, REUSE, REWORK and RECYCLE

  4. REDUCE, REGENERATE, REWORK and RECYCLE
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The 4R principle is Reduce, Reuse, Recycle and Recover. This principle is environment friendly and would help reduce environmental pollution to an extent.


The principle directs people to


•reduce the usage of resources. Use them only if necessary.


•reuse the resources (or materials) if possible. For example, reusing cloth bags for shopping.


•recycle materials if they are no longer usable.


•recover materials; converting waste into usable resources.

Hence, the correct option is $\text{B}$

Plastic __________ the percolation of water into the soil and prevents replenishment of ground water.

  1. increases

  2. reduces

  3. doesn't affect

  4. varies
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Groundwater moves through soil and rocks, picking up pollution along the way. Plastic trash can affect groundwater quality, especially if you dispose of it improperly. It reduces the percolation of water as it comes in the way as water moves through soil.
