Abstract—The crude recycling of electronic waste (e-waste) reported concentrations of PCDD/Fs in various environmental
in developing counties such as China has presented a partments at e-waste recycling centers, as well as the
environment pollution that affects both ecosystems and the estimated levels of human exposures [3], the potential
people living within or near the main recycling areas in recent environmental risk of discarded e-waste open burning sites
years. Although several studies have reported concentrations of scattered at villages is less concerned. In this study,
trace metals and several typical anic pollutants in polychlorinated dioxins and furans (PCDD/Fs) in 15 samples,
various partments at e-waste recycling busted residue, dust, soil and sediment collected
centers, as well as the estimated levels of human exposures to the from a discarded e-waste open burning site and its vicinage in
interested contaminants, the potential environment
