C. SHORT ANSWER QUESTIONS

(Page-225)
Question 1. Define the following terms :
(i) Biodegradable waste
(ii) Pollutant
(iii) Thermal pollution
(iv) Eutrophication
(v) Biomedical waste
(vi) Biomagnification
Answer :
(i) biodegradable waste as “any waste that is capable of undergoing anaerobic or aerobic decomposition, such as food and garden waste, and paper and cardboard.”
(ii) A pollutant is a substance that is present in concentrations that may harm organisms (humans, plants and animals) or exceed an environmental quality standard. The term is frequently used synonymously with contaminant
(iii) Thermal pollution is any deviation from the natural temperature in a habitat and can range from elevated temperatures associated with industrial cooling activities to discharges of cold water into streams below large impoundments
(iv) Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
(v) Biomedical waste is defined as any waste, which is generated during the diagnosis, treatment or immunisation of human beings or animals, or in research activities pertaining thereto, or in the production or testing of biologicals
(vi) Biomagnification is defined as the accumulation of a particular substance in the body of the organisms at different trophic levels of a food chain. One example of biomagnification is the accumulation of insecticide DDT which gets accumulated in zooplanktons
Question 2. State three ways by which:
(i) Air gets polluted
(ii) Water gets polluted
(iii) Soil gets polluted
Answer :
(i) Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog
(ii) Contaminants such as chemicals, nutrients, and heavy metals are carried from farms, factories, and cities by streams and rivers into our bays and estuaries; from there they travel out to sea. Meanwhile, marine debris—particularly plastic—is blown in by the wind or washed in via storm drains and sewers
(iii) Soil pollution is often caused by the uncontrolled disposal of sewage and other liquid wastes resulting from domestic uses of water, industrial wastes containing a variety of pollutants, agricultural effluents from animal husbandry and drainage of irrigation water
Question 3. Describe the harmful effects of:
(i) Burning of fossil fuels
(ii) Air pollution
(iii) Noise pollution
(iv) Soil pollution
Answer :
(i) Fuels such as coal, and petroleum release unburnt particles into the environment. The particles result in air pollution and cause respiratory diseases such as respiratory illness, lung damage, ozone (smog) effect, reduces the ability of blood to bring oxygen to the blood cells and tissues, liver and kidney, etc
(ii)
- Respiratory and Heart Problems. The effects of air pollution are alarming. …
- Child Health Problems. Air pollution is detrimental to your health even before you take your first breath. …
- Global Warming. …
- Acid Rain. …
- Eutrophication. …
- Effect on Wildlife. …
- Depletion of the Ozone Layer
(iii) Noise pollution adversely affects the lives of millions of people. Studies have shown that there are direct links between noise and health. Problems related to noise include stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity
(iv) The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield. The contaminated soil is then used to produce fruits and vegetables, which lacks quality nutrients and may contain some poisonous substance to cause serious health problems in people consuming them.
Question 4. Name any two waterborne diseases caused by contaminated water.
Answer : The result: dangerous diseases like cholera and typhoid fever. Other waterborne diseases include diarrhoea, dysentery, polio and meningitis. Unclean water for washing can cause skin and infectious eye disease
Question 5. Name the gas that caused the Bhopal gas tragedy. Which organisation was responsible for leakage of this gas?
Answer : The Bhopal disaster occurred when about 45 tons of the gas methyl isocyanate escaped from a plant owned by a subsidiary of the U.S.-based Union Carbide Corporation.
Question 6. Mention any two effects of air pollution on human health.
Answer : Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.
Question 7. Explain any two effects of eutrophication.
Answer : The known consequences of cultural eutrophication include blooms of blue-green algae tainted drinking water supplies, degradation of recreational opportunities, and hypoxia.
Question 8. What are Bharat Stage Vehicular Standards?
Answer : Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from compression ignition engines and Spark-ignition engines equipment, including motor vehicles
Question 9. Define Euro standards
Answer : Formally introduced by the European Union (EU) in 1992, the Euro Emissions Standards are a set of regulations designed to define the acceptable amount of exhaust emissions that vehicles sold in the EU can release
