Question 1

which of the integrated waste management is reduced on an individual level?
A) Source reduction
B) Recycling
C) Disposal
D) Burning

Accepted Answer

Source reduction involves minimizing waste before it is created, which can be achieved on an individual level through actions like using less packaging or choosing reusable products.

Question 2

which of the following can be recycled many times?
A) Plastic
B) Wood
C) Organic materials
D) Aluminum

Accepted Answer

Aluminum can be recycled many times without losing its quality or properties, making it highly recyclable compared to the other options listed.

Question 3

what is called for the process of burning municipal solid waste in a properly designed furnace under suitable temperature and operating conditions?
A) Landfill
B) Recycling
C) Vermicomposting
D) Incineration

Accepted Answer

Incineration is the process of burning municipal solid waste in a specially designed furnace under high temperatures and appropriate operating conditions to reduce its volume and weight, and sometimes to generate energy.

Question 4

what is the order of waste management hierarchy, from most to least favoured
A) Prevention- Recycle- Reuse- Disposal
B) Prevention- Reuse- Disposal- Recycle
C) Prevention- Disposal- Reuse- Recycle
D) Prevention- Reuse- Recycle-Disposal

Accepted Answer

The waste management hierarchy prioritizes waste management strategies from most to least environmentally preferred. It starts with prevention (minimizing waste creation), followed by reuse (using items again), recycling (processing materials for new uses), and finally disposal (landfill, incineration, etc.).

Question 5

_____ devices remove materials which would damage equipment or interfere with a process.
A) Grit
B) Screening
C) Oxidation
D) Reduction

Accepted Answer

Screening devices are used to remove materials that could cause damage to equipment or interfere with a process by physically separating these materials from the flow.

Question 6

______ represents the heavier inert matter in wastewater.
A) Debris
B) Waste
C) Screens
D) Grit

Accepted Answer

Grit represents the heavier inert matter in wastewater, such as sand, gravel, cinders, or other heavy solid materials that are not readily decomposable.

Question 7

what is the most common used coagulant?
A) Alum
B) Ferric sulphate
C) Limestone
D) Coal

Accepted Answer

Alum (aluminum sulfate) is the most commonly used coagulant in water treatment processes for the removal of suspended solids and colloidal particles.

Question 8

which gas is mainly produced due to incomplete burning of wood? A) CO B) SO₂ C) NO₂ D) NO₃

Accepted Answer

Carbon monoxide (CO) is primarily produced from the incomplete combustion of wood, due to insufficient oxygen for the wood to fully convert into carbon dioxide (CO2).

Question 9

which of the following is involved in production of carboxy hemoglobin. A) CO B) SO₂ C) NO₂ D) NO₃

Accepted Answer

Carboxyhemoglobin is formed when carbon monoxide (CO) binds with the hemoglobin in red blood cells. This binding is much stronger than the binding of oxygen to hemoglobin, which interferes with the blood's ability to carry oxygen throughout the body.

Question 10

which of the following is a liquid form of aerosol?
A) Fume
B) Dust
C) Mist
D) Smoke

Accepted Answer

Mist is a liquid form of aerosol, consisting of tiny liquid droplets suspended in the air.

Question 11

X ray films are a source of which of the following gas? A) SO₂ B) CO₂ C) NO₂ D) SO₃

Accepted Answer

The answer of X ray films are a source of...

Question 12

which of the following leads to a disease called broncho spasm? A) SO₂ B) SO₃ C) SO₄ D) CO₂

Accepted Answer

The answer of which of the following leads to a...

Question 13

which air pollutant cause corrosion of building? A) SO₂ B) SO₃ C) CO D) NO₂

Accepted Answer

Sulfur dioxide (SO₂) is a significant air pollutant that can lead to the formation of acid rain, which causes corrosion and damage to buildings and structures.

Question 14

which of the following air pollutant effects plants the most? A) Fluorine B) SO₂ C) PAN D) HCL

Accepted Answer

Fluorine is a highly reactive gas that can cause damage to plant leaves, stems, and flowers. It can also interfere with photosynthesis and reduce plant growth.

Question 15

which of the following is used in ceramic industries?
A) Electrostatic precipitator
B) Dynamic precipitator
C) Spray tower
D) Wet cyclonic scrubber

Accepted Answer

The answer of which of the following is used in...

Question 16

which of the following air pollution control device has maximum efficiency?
A) Electrostatic precipitator
B) Dynamic precipitator
C) Spray precipitator
D) Wet cyclonic scrubber

Accepted Answer

Electrostatic precipitators have a very high efficiency for removing particles from an airstream, often above 99%, making them more efficient compared to other types of precipitators and scrubbers listed. They work by charging particles electrically and then collecting them on charged plates.

Question 17

which of the following is incorrect regarding the fabric filter?
A) They can remove very small particle
B) They are liable to chemical attack
C) They have low efficiency in comparison to venturi scrubber
D) They can handle large volume of gas at relatively high speed

Accepted Answer

Fabric filters, also known as baghouse filters, are highly efficient at removing small particles from gas streams, often achieving more than 99% efficiency, which can be comparable to or better than the efficiency of venturi scrubbers depending on the specific application and conditions.

Question 18

which of the following removes both gaseous and particulate contaminants?
A) Venturi scrubber
B) Gravitational settling chamber
C) Dynamic precipitator
D) Wet scrubber

Accepted Answer

Venturi scrubbers are designed to remove both gaseous and particulate contaminants by using a high-velocity gas stream to atomize a liquid, which then captures the contaminants.

Question 19

where undertaken, EIA should be used to help determine whether consent is given for development.
A) Never
B) Hardly ever
C) Often
D) Always

Accepted Answer

Environmental Impact Assessments (EIA) are a critical tool used to evaluate the potential environmental effects of a proposed project before proceeding. They are designed to ensure that decision-makers consider environmental impacts when deciding whether to approve a development. Therefore, EIAs should always be used to help determine whether consent is given for development.

Question 20

the primary reason for EIA is to
A) Mitigate existing environmental impacts of development
B) Predict the size of impacts of developments
C) Describe proposed developments
D) Identify the environmental consequences of development in advance

Accepted Answer

The primary reason for Environmental Impact Assessment (EIA) is to identify the environmental consequences of development projects in advance, allowing for the consideration of environmental impacts in the planning and decision-making process.
