Aurangabad, May 12: Pollution levels were significantly reduced in the first lockdown last year. However, a slight increase in pollution levels has been seen in the current lockdown. The city's air quality index had risen to 113 for several hours on Wednesday, a trend that has continued for several days. Although, in the afternoon, the air quality index is declining, it sees a sharp increase in evening and morning hours.
In the first lockdown, from March to May, the vehicular movement was completely closed. As a result, air pollution was found to be significantly reduced. As the air pollution was reduced, the visibility increased in the city. After the first lockdown, however, the pollution increased again and the situation almost returned to normal. Only vehicular movement has been reduced and companies and offices are running along with all the essential services. Due to these reasons, the level of pollution has increased in many parts of the city. According to Maharashtra Pollution Control Board, the air quality index had reached 113 around 12 noon, which is considered dangerous for children, elderly and sick. Normally, the air quality index level remained at 113 till 3 pm. The level dropped to 86 after 3 pm and rose to 90 again. In addition, the levels of PM2.5, PM10, ozone, nitrogen oxides, sulfur dioxide and carbon monoxide were found to be slightly below the maximum level. Despite some relief, there are definitely signs of increased pollution after the lockdown.
Tree felling, burning garbage leading to pollution
On the one hand, huge trees have been cut down, while on the other hand, cement roads have been built in most parts of the city. So the temperature rises by at least half a degree. In addition, cement roads and low trees create smog in the atmosphere. Likewise, burning garbage, pollution from companies and vehicles are also contributing to the increase in air pollution, said nature lover and researcher Dr Shivam Barule.
