It should be known that it should not exceed 60 and 100 respectively.
On the other hand, according to SAFAR India, an air quality monitoring organization under the Union Ministry of Earth Sciences, there is no scope for improvement in pollution for the next two-three days. Due to low temperature and freezing in the air, pollutants will not be able to fly. In such a situation, the air index is expected to remain in a very poor category. In such a situation, the elderly, children and sick people need to be cautious.
