Abstract Many epidemiological studies have shown that ambient and personal concentration of both fine and ultrafine aerosol in urban environment are related to adverse cardiovascular effect, increased case of heart rate variability (HRV). We investigated the effect of aerosol and its components on the root mean square of successive differences (RMSSD) and standard deviation of normal-to-normal intervals (SDNN) and low to high frequency ratio (LF/HF) and ST segment depression/elevation. Sampling has been done at road site near the Main gate of IIT-DELHI, HAUZ KHAS, NEW DELHI during July 2017 to December 2017. The Electrocardiograph of healthy security guards stationed at main gate was recorded for 5-6 hours. The mass of aerosol was collected using SKC multi-stage cascade impactor for mass, and real time BC was monitored using aethalometer. The quartz filters were used to determination of EC (elemental carbon), and OC (organic carbon). Concentrations of PM2.5 range from 208 to 547 µg/m³ and black carbon ranged from 2.0-40.3 µg/m³. These concentrations were significantly higher than those reported for developed countries. Therefore, we expect that the link between HRV parameters (i. e. indicator of arrhythmia), PM2.5 and BC to be entirely different than those reported for developed countries. The statistical link between PM2.5, BC and HRV will be discussed.
