Noise pollutionYou may live on a main road, or have noisy neighbours. Either way, a third party cost is imposed upon you through noise pollution. In some studies, this can be associated with increased blood pressure and heart conditions. Obviously a very serious externality.Who is the third party?What is the externalities?Good or bad?When does the spillover occurs?

Air pollutionAs manufacturers produce cars, televisions, and other goods – they leave Carbon emissions. An example of this was visible in 1952 during ‘The Great Smog of London’. Over the course of 5 days, it is estimated that 6,000 died from air pollution. Obviously this is a very extreme case but is an example of how there can be serious external effects from air pollution.Who is the third party in this serious case of air pollution?What is the externalities?Good or bad?When does the spillover occurs?

Refer to the following article to answer the next two questions.  Noise Exposure and Public HealthExposure to noise constitutes a health risk. There is sufficient scientific evidence that noise exposure can induce hearing impairment, hypertension and heart disease, annoyance, sleep disturbance, and decreased school performance. For other effects such as changes in the immune system and birth defects, the evidence is limited. Most public health impacts of noise were already identified in the 1960s, and noise abatement is less of a scientific but primarily a policy problem. A subject for further research is the [clarification] of the mechanisms underlying noise-induced cardiovascular disorders and the relationship of noise with annoyance and non-acoustical factors modifying health outcomes. A high-priority study subject is the effect of noise on children, including cognitive effects and their reversibility. Noise exposure is on the increase, especially in the general living environment, both in industrialized nations and in developing world regions. This implies that in the twenty-first century noise exposure will still be a major public health problem. Which of the following best describes why the authors claim that reducing noise exposure is currently more of a public policy problem than a scientific problem?There is sufficient scientific evidence that noise exposure can induce hypertension and heart disease.⊝The relationship of noise with annoyance that negatively impacts human health is a subject for future research.⊝Most public health impacts of noise were already identified in the 1960s.⊝It is unclear whether negative cognitive effects are reversible in humans.⊝CLEAR ALL

1. Although pollution of land, sea and air has been well documented, the latest and the least recognisedversion is the swelling tide of noise which is engulfing urban as well as rural areas. This has long-termimplications on the ecology, health, and productivity of a fast developing country like India.2. Unlike other pollutants, noise lacks visibility, seldom registering on the consciousness, except asa trifling irritant to be dismissed at will, therefore, less likely to be perceived as a threat. Availabledata indicates that noise does pose a threat and is known to have caused a number of complications.Declining productivity among workers in certain industries has been directly correlated with noiselevels, particularly these under constant exposure to the menace.3. The first ever survey of the impact of noise on health, conducted by All India Institute of MedicalSciences, has established that noise not only impairs the physical and psychological functioning of thehuman organism, but also causes nausea, vomiting, pain, hypertension and a lot of other complications,including cardio-vascular complaints.4. A study by Post Graduate School of Basic Medical Sciences, in Chennai, confirms such conclusions. In50 per cent of industries, it was found that workmen exposed to higher intensities of noise in occupationalcapacities were often irritated, short-tempered, and impatients and more likely to resort to agitation anddisrupt production. This was true of units in heavy industrial pockets in and around the four metropolitancentres.5. Recreational noise, another ugly facet, is becoming more widespread in cities and towns. Loudspeakersare turned at full volume during marriages, festivals, jagrans, musical programmes, particularly atnight, without the least consideration for others. Even at 50 db sound can awaken a person from a deepslumber. As experiments have shown, loudspeakers with output from 60 to 80 db cause the pupils ofa slumbering person to dilate, with increasing intake of oxygen, resulting in palpitation. The effect ismore pronounced in narrow lanes. TV sets are played at full volume at prime time, invariably disturbingneighbours. Noise-making seems to have become the latest status symbol, be it an election campaign orslogan shouting or advertising ownership of a TV set.Page 2 NODIA Sample Paper 1 CBSE X EnglishClick the Following Button to See the Free MS/SolutionsAnswer the following questions, based on the passage above.i.
