EMISSION LEVELS OF POLYCHLORINATED DIBENZODIOXINS AND DIBENZOFURANS (PCDDs/PCDFs) FROM WASTE INCINERATORS IN INDIA
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are recognized as persistent organic pollutants (POPs) and included in priority list for action under Stockholm Convention. Waste incinerators are prime sources for influx of PCDDs/PCDFs into the environment. In recent years studies have been continuously carried out world-wide on the emissions of these pollutants from incinerators in India also, studies are being undertaken on assessment of the levels of PCDDs/PCDFs in biological matrices and ambient air particulate matter including emissions from waste incinerators in India. The emission levels of total dioxin/furan in this study have been found as 498.40, 139.23 and 195.34 pg I-TEQ/m3 respectively from biomedical waste, industrial process waste, and hazardous waste incinerator. The detected congener pattern shows that high chlorinated dioxins are dominant in all the samples while low chlorinated furans are higher in biomedical waste incinerator except hepta and octa furans in hazardous waste incinerator. Congener pattern and group homolog profile is also presented.
