PAHs from Waste Incineration main Achievements Dr. Vinit Prakash Department of Chemistry Maharishi Markandeshwar University Mullana, Ambala (Hry)
PAHs from Waste Incineration Objectives during Ph.D. 1.To analyses the formation of 16 PAHs from incineration of waste from Acrylic industry/ local hospital. 2.To analyses waste management practices followed by Acrylic industry/local Hospitals and the problems faced by them in complying with the environmental regulations.
PAHs from Waste Incineration 16 PAHs as Priority Pollutants (EPA, 1997) 1.Naphthalene(Nap) 2.Acenaphthylene(AcPy) 3.Acenaphthene(Acp) 4.Fluorene(Flu) 5.Phenanthrene(PA) 6.Anthracene(Ant) 7.Fluoranthene(FL) 8.Pyrene(Pyr) 9. Chrysene(CHR) 10. Benzo[a]anthracene(BaA) 11. Benzo[b]fluoranthene(BbF) 12 Benzo[k]fluoranthene(BkF) 13. Benzo[a]pyrene(BaP) 14. Indeno(1,2,3-c,d)pyrene(IND) 15 Benzo(g,h,i)perylene(BghiP) 16. Dibenzo(a,h)anthracene(DBA) 2A Carcinogenic 2B Carcinogenic It is expected that air quality would be improved if the emission of these PAHs is controlled
