Waste Management and Pollution Questions

Multiple choice commercial studies waste generation and management e-waste management e-wastes waste generation

Biomedical waste may be disposed of by

  1. Incineration

  2. Autoclaving

  3. Land filling

  4. Both B and C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biomedical waste may be infectious waste include discarded blood, sharps, unwanted microbiological cultures and stocks, body parts after amputation. The wastes may also include bandages and dressings, discarded gloves, other medical supplies that may have been in contact with blood and body fluids, and laboratory waste. This waste is highly infectious. The method used for the disposal of biomedical waste is incineration. Incinerators are operated at very high temperatures. This temperature kills and destroys the microorganisms and pathogens. Autoclaving is done for reusable products like gloves. 

So, the correct answer is option A.

Multiple choice chemistry for a pollution free nature properties of soil soil pollution and its effects soil and soil pollution

The portion of solid waste that is hazardous is: 

  1. paper

  2. food waste

  3. agricultural waste

  4. battery metals
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The portion of solid waste that is hazardous are oils, battery metals, heavy metals from smelting industries and organic solvents. These can in the long run, get deposited to the soils of the surrounding area and pollute them by altering their chemical and biological properties. They also contaminate drinking water aquifer sources. More than 90% of hazardous waste is produced by chemical, petroleum and metal-related industries and small 
businesses such as dry cleaners and gas stations contribute as well.

Multiple choice biology interdependence in living beings - plants and animals animals as consumers scavengers and decomposers interdependence between plants and animals

For recycling of materials, which of the following is most necessary?

  1. Producers

  2. Consumers

  3. Decomposers

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biogeochemical cycle mainly involves the exchange of materials between biotic and abiotic components of the biosphere. The bio - genetic nutrients are essential elements required by organisms for their body building and metabolism which are provided by earth and returned to earth after the death of organisms and/or through excreta of animals. The decay of excreta and dead bodies of organisms is carried out be decomposers. The activity of decomposers releases the bio - genetic nutrients from excreta and dead bodies of organisms. Hence decomposition activity is most important part of biogeochemical cycles. Else all the nutrients will slowly become trapped in excreta and dead bodies of organisms.

So, the correct answer is option C.

Read the following statements and select the incorrect one.

  1. Little decomposition occurs during the formation of primary sludge

  2. formation of primary sludge requires ample aeration.

  3. Activated sludge possess flocs of decomposer microbes

  4. Formation of activated sludge requires aeration.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Little decomposition occurs during the formation of primary sludge. Activated sludge possess flocs of decomposer microbes. Formation of activated sludge requires aeration. But formation of primary sludge does not requir ample aeration. So, the correct option is 'Formation of primary sludge requires ample aeration'

Multiple choice types, sources and impact of waste accumulation waste management - impact of waste accumulation our life and environment geography

 The term ISWM refers to ________.

  1. Integrated Solid Waste Machine

  2. International Solid Waste Mechanism

  3. International Solid Waste Management

  4. Integrated Solid Waste Management
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Integrated solid waste management involves the comprehensive process of dealing with waste such as collection, recycling, source reduction, transportation, and landfilling. The waste gets completely treated and safe disposal is made after all the process that renders waste reusable, reduced and recycled.
