Another study was conducted in the open air at a place called Karawal Nagar in East Delhi where a large scale Yagya of 108 Kunds was performed. The sampling was done in the same way as in the case of indoor experiments and a comparison of the microbe colony counts during and after Yagya was made with the background . The experiment continued from 12th to 16th of Yagya and the sampling was continued till two days after the Yagya. The results show that in comparison with the background counts, there was a reduction of 55% in bacteria, 15% in fungi, and 79% in the pathogens on the next day after the Yagya was over. The reduction in pathogens was 79% even on the second day after Yagya. The total microflora had reduced by 49% on the 2nd day after Yagya.
In order to study the effect of Yagya on the gaseous pollutants, two experiments were performed in the open air. Samples of air were collected by CPCB in one case and by Envirotech in the second case and analyzed for gaseous pollutants SO2 and NO2 . The two experiments were performed at M.S. Apartments, K.G. Marg, New Delhi, in the open air in January 2004 and February 2005, respectively. In both the experiments the objective was to see if there was any effect of performing Yagya in the open air on the gaseous pollutants. The results in both the cases were encouraging. In the first experiment there was a reduction of 47% in NO2 on the day of Yagya and 60% on the next day. In case of SO2, the reduction was 86% on the day of experiment and almost 100% on the next day as the SO2 was below detection level.
