Supreme Court Asks Delhi Govt, Says Odd-Even May Not Be the Solution.

School reopened on Monday after it was declared shut for two days last week due to the poor quality air. Stubble burning in the neighbouring states has not decreased and it is adding to the worsening air. Regarding the implementation of the odd-even scheme in the national capital again, CM Arvind Kejriwal had said on Monday that the skies have turned clear and there is no need for it. The odd-even scheme was started by the Delhi government to curb the rising pollution, but Supreme Court on Friday questioned on its effectiveness.

The AQI between the range of 51 to 100 is considered as satisfactory; 101-200 is moderate; 201-300 falls under the category of poor. While 300-400 is considered as 'very poor', levels between 401-500 fall under the 'hazardous category'.
