| Abstract: | The vapour phase acetic and formic acid levels were measured at two different sites of Delhi. Mean formic and acetic acid levels were found to be 1.66±0.81 and 5.83±2.24 ppbv, respectively, at the urban site of Rohini, while they were 2.51 ±1.22 and 2.92±1.78 ppbv, respectively, at National Physical Laboratory (NPL), a semi-urban site. Strong correlation between formic and acetic acids was observed at Rohini (correlation coefficient r=0.73) indicating similar source type for both the acids at this site, while at NPL, the correlation was very weak (r=0.19) indicating different sources of two acids. |
