Question

compare the air quality ,water quality and sound quality of Delhi and Sikkim.

​

Answer 1

Explanation:

Air pollution is responsible for many health problems in the urban areas. Of late, the air pollution status in Delhi has undergone many changes in terms of the levels of pollutants and the control measures taken to reduce them. This paper provides an evidence-based insight into the status of air pollution in Delhi and its effects on health and control measures instituted. The urban air database released by the World Health Organization in September 2011 reported that Delhi has exceeded the maximum PM10 limit by almost 10-times at 198 μg/m3. Vehicular emissions and industrial activities were found to be associated with indoor as well as outdoor air pollution in Delhi. Studies on air pollution and mortality from Delhi found that all-natural-cause mortality and morbidity increased with increased air pollution. Delhi has taken several steps to reduce the level of air pollution in the city during the last 10 years. However, more still needs to be done to further reduce the levels of air pollution.

Explanation:

DELHI

1. Air pollution is caused by a number of pollutants such as ozone, carbon monoxide, nitrogen dioxide, methane, sulphur dioxide, benzene and mercury. But the key pollutants in Delhi—and probably the deadliest—are PM2.5 and PM10. These fine particles can settle deep in the lungs and can even be absorbed in our bloodstream, which can lead to increased respiratory and cardiovascular diseases among people.
2. Similarly, noise pollution levels crossed the safe limit at all 10 locations where they were monitored both during the day (6am to 10pm) and at night (10pm to 6am).
3. Yamuna, the main source of water for Delhi, is one of the most polluted rivers in the country. Nineteen drains in the capital flow into the river contributing 96 per cent on the total pollutants in Yamuna. Just five per cent of the sewage that is discharged into the river is treated, posing a serious health hazard.

SIKKIM

1. The newest sound in Gangtok, Aenon Sound is creating waves all over, this Red Panda Winter Festival. Their world class audio standards has been getting appreciation from artists and locals alike. Never before had MG Marg resonated to a sound of this magnitude and quality.
2. According to Binod, the drummer of Sabin Rai and the band, the drum kit provided by Aenon came as a surprise to him and was beyond his expectation. For Nima Rumba,who has had numerous concerts in Gangtok before, this has been by far his best.
3. The results showed that most of the water samples were in poor condition (85.3%) and very few of them were in good condition (2.6%). The water quality of the natural sources indicated that the water is poor-quality and not totally safe for human consumption, and that it needs treatment before consumption.
4. Currently 605,495 people in Sikkim are breathing toxic air that does not meet WHO's clean air guidelines. The district with the worst air pollution in Sikkim is East Sikkim , where PM2. 5 is forecasted to be 12.8 µg/m3 . That's good.
