| Abstract | This study aimed to investigate As, Cd, Cr, Pb, Mn and Zn quantities in water, sedimentand two edible aquatic plants (Ottelia alismoides and Ipomoea aquatic). The samples werecollected from five sampling sites near an electronic waste (e-waste) dumpsite in Kalasinprovince of Thailand. Heavy metal quantity, bioaccumulation factors (BAFs) and inter-simplesequence repeats (ISSR) analysis were evaluated in two edible aquatic plants near an e-wastedumpsite and was compared with a reference area. The As and Pb quantities in the watersamples from the e-waste dumpsite exceeded the surface water quality standard. In the sediment, heavy metal quantities were significantly higher than those in the reference area. The As, Cd, Cr, Pb and Zn quantities in O. alismoides near an e-waste dumpsite were higher than the food standards. The Pb quantity in I. aquatic near an e-waste dumpsite was greater than the food standards of the FAO/WHO. The highest BAFs of As (2.27 ? 0.12), Cd (1.40 ? 0.11) and Mn (22.73 ? 1.65) were found in O. alismoides. The genetic similarity values ranged from 0.43 - 0.99 in O. alismoides and from 0.42 - 0.98 in I. aquatic. These results indicated that heavy metals near e-waste accumulated in the two aquatic plants might be a factor in genetic differentiation. |
