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.

2A Carcinogenic 2B CarcinogenicIt is expected that air quality would be improved

if the emission of these PAHs is controlled
