[email protected] Hazardous persistent organic pollutants including polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) associated with informal electronic waste (e-waste) recycling process is an emerging environmental problem in India. Hence we took the first attempt to measure the toxic equivalents (TEQ) of dioxins and furans in surface soil and passive air samples collected from informal e-waste recycling facilities and open dumpsites in India by using Chemically Activated Luciferase Expression (CALUX) bioassay. CALUX TEQs for PCDD/Fs was measured in the informal e-waste recycling sites engaged in crude process of extracting precious metals and compared with the CALUX TEQs from the open dumpsites from three major metropolitan cities of India viz., Chennai, New Delhi and Mumbai. Highest CALUX response of 658 pg CALUX TEQ/g in soil was observed in solid waste © 2016 American Chemical Society Loganathan et al.; Persistent Organic Chemicals in the Environment: Status and Trends in the Pacific Basin Countries I ...
