AIR BORNE PARTICULATE BOUND POLYCHLORINATED DIBENZODIOXINS AND DIBENZOFURANS (PCDDs/Fs) LEVELS IN DELHI, INDIA
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofuran (PCDFs) are globally wide spread, and persistent environmental pollutants. The four sampling locations namely ITO (n=13), Siri Fort (n=12), Janakpuri (n=7) and Shahdara (n=9) have been selected for monitoring of PCDDs/Fs in air borne particulates in ambient air at Delhi. ITO is busy traffic intersection with two nearby Coal based and Gas based thermal power plants, Siri Fort and Janakpuri are the residential sites while Shahdara an Industrial site. The identification and quantification of PCDDs/Fs were performed by HRGC-HRMS (JEOL JMS-800D, Japan) coupled to auto sampler using a positive electron ionization (EI+) source operated in Selective Ion Monitoring (SIM) mode at 10000 or better resolution. The average deposition of total 2,3,7,8-subsituted PCDDs/Fs congeners were found as 0.971 pg I-TEQ/m3 at ITO monitoring site, 0.570 pg I-TEQ/m3 at Siri Fort, 0.631 pg ITEQ/ m3 at Janakpuri and 1.250 pg I-TEQ/m3 at Shahdara industrial site.
