Аннотация

Due to rapid growth of Delhi city and nearby areas, air pollution problem is everybody's concern. In spite of some measures taken by the government, the levels of air pollutants have increased drastically, especially during past two decades. Recently, the Delhi government called for odd-even trial during January 1–15, 2016. In general, the trial was successful for saving travelling time across the city destinations. However, the results indicated no significant reduction in PM2.5, PM10 and CO levels at various sites in the city. At Anand Vihar site, PM2.5 level was recorded as 381 μg/m3 on 31st December 2015 before the implementation of the odd-even trial while 400 μg/m3 on January 1st, 2016. Similarly, CO level was 108 μg/m3on 31st December, 2015 and 113 μg/m3 on January 1st, 2016 suggesting no significant change in the values. Nevertheless, the exercise suggested that the public of Delhi is highly disciplined and can march in tune with the difficult calls of government for any common cause of community life. The experiment is seen as social networking tool which compelled people to come closer for sharing the vehicles. Since, the particulate matter is naturally high due to suspension of soil and road dust in north India, such trials should be done in the months of July and August when soil is relatively wet and road dust suspension is minimum.  Keywords: Delhi city, odd-even trial, air pollution, PM 2.5, vehicular exhaust
