| Abstract |
Heavy metals from electronic waste (e-waste) accumulate in the environment and can affect
human health. The purpose of this study was to determine As, Cd, Cr and Pb concentrations in
water, sediment and three species of edible aquatic plants (Ottelia alismoides, Ipomoea aquatic
and Marsilea crenata) near an e-waste open dumpsite. Samples were collected from six sampling
points surrounding an e-waste open dumpsite and heavy metal concentrations were analyzed by
inductively coupled plasma optical emission spectrometry (ICP-OES). Bioaccumulation factors
(BAFs), estimated daily intake (EDI), hazard quotient (HQ), hazard index (HI) and carcinogenic
risk (CR) were evaluated in the plants. The Pb concentration in the water samples exceeded the
quality standard. The order of the heavy metal concentrations in the sediment was Pb>Cr>As
>Cd, and these concentrations were within the limits of the quality standard. The order of the
heavy metal concentrations in O. alismoides, I. aquatic and M. crenata was Cr>Pb>As>Cd,
Pb>Cr>As>Cd and Pb>Cr>As>Cd, respectively. The concentrations of As, Cd, Cr and Pb in
O. alismoides and As, Cr and Pb in I. aquatic and M. crenata exceeded the quality standard of
food consumption. Most of the BAF values of the heavy metals in O. alismoides were more than
one, but in I. aquatic and M. crenata, they were less than one. The order of the EDI values in
O. alismoides, I. aquatic and M. crenata was Cr>Pb>As>Cd, Pb>Cr>As>Cd and Cr>As>Pb
>Cd, respectively. The HQ values were greater than one for As, Cd and Pb in O. alismoides; Pb
in I. aquatic; and As and Pb in M. crenata. The HQ and CR values show that the consumption
of edible plants from an e-waste open dumpsite is a human health risk |
