Rajouri, Lajpat log high level of pollutants April 22

West Delhi's Rajouri Garden and south Delhi’s Lajpat Nagar have logged a high level of pollutants on April 22, the ninth day of the odd-even car-rationing scheme which experts maintain will have a “marginal” impact on the city’s overall air quality.

Sumit Sharma, R. Suresh and Jai Malik of Teri, who are analysing the impact of ongoing curb on vehicular traffic, explained the daily fluctuations in level of pollutants are observed largely due to meteorological factors like wind speed.

“Wind speeds have been lower during the odd-even week in comparison to the week before. This is one of the reasons why pollutant concentrations were higher during the odd-even week with respect to the week before,” they said in a statement.
