Nitrates and Phosphates

Phosphates

Nitrates, DDT

Cadmium and DDT

Eliminates or reduces the number of organisms sensitive to high temperature

May enhance the growth of plants and fish in extremely cold areas

Cause damage to the indigenous flora and fauna

All of these

By utilising only artificial processes

By utilising only natural processes

By utilising both artificial and natural processes

By utilising advanced and more expensive means

The town of Arcata along northern coast of California and biologist Purdue University

The conventional sedimentation, filtering and chlorine treatment were performed in first stage

To remove dissolved heavy metal the biologist developed a series of 10 connected marshes

Only bacteria were seeded here in marshland

All of these

6 Marshlands of 60 hectares

Appropriate plants, algae, fungi and bacteria were seeded into this marshland

Such arrangements actually neutralize, absorb and assimilate the pollutants

All of these

A citizens group called Friends of Arcata Marsh, India

Responsible for the upkeep and safeguarding of integrated waste water management project of Arcata

Comes under Government of India

All of these

Sanctuary with a high level of biodiversity in the form of fishes, animals and birds

Appropriate plants, algae, bacteria neutralize, absorb and assimilate the pollutants

Both A and B

Act as ecological sanitation

Using dry composting toilets

Recycling human excreta into resource as a natural fertilizer

Both A and B

Using toilets which have a connection to the sewage

Practical and cost effective approach

Unhygienic and efficient approach

Reduces the reliance on chemical Fertilizer

All of these

Sanitary Landfills

Sanitary sinks

Sanitary dispose house

Sanitary cabinets

Not a complete solution of solid wastes in metro cities

Danger of seepage of the chemicals

Chances of polluting underground water resources

Has three categories on the basis of ease of degradability

Waste can be categorised into three categories- Bio-degradable, Recyclable and Non-biodegradable

Reduction of garbage generation is our prime goal by using milk and water in Polybags

Hospital waste is directly transferred to landfills or open dumps

All of these

Using incinerators

Using landfills

Using scrubber

Using precipitator

E-wastes are burried in landfills or incinerated

Over half of the e-wastes generated in the developed world are exported to developing countries mainly to China, India and Pakistan

Developing countries, recycle the waste and recover the metals like Platinum, cadmium and chromium

Developed countries have facilities for recycling of metals from E-waste while developing countries do it manually and expose workers to toxic substances

In a solution of waste water treatment

Solution to ever increasing problem of accumulating plastic waste

Organic Farming

Ozone protection

Polythene

Powdered form of Bitumen

Fine powder of recycled modified plastic

Polyester

R.V. College of Engineering and Bangalore City Corporation were also involved in the project

They used polyblend and bitumen

Raw material for creating polyblend is any plastic film waste

Used to construct houses in Kerala

As it increases the cementing power

As it enhances the bitumen’s water repellent property

As it makes the newly constructed road get easily dry

Toxicity to non target organisms

Toxicity to important components of the soil ecosystem

Eutrophication

All of these

Integration of all technique to produce more efficient and better crops

Cyclical zero waste process where products of one process serve as nutrient for another process

Mixing of all types of crops so that one may take out the best out of it without using chemical fertilisers

All of these

Organic Farming

Integrated waste water treatment

Solution to solid waste

More than one option

Accidental leakage

Safe disposal of radioactive waste

Global warming

Both A and C

Three mile Island

Chernobyl Incident

Bangalore

Both A and B

Lethal at high doses

Causes cancer at low doses

Should be stored in the shielded containers buried within rocks about 100m deep

An extremely potent pollutant
