It was found that some river sediments in Guiyu were contaminated with Cd (n.d.-10.3 mg/kg), Cu (17.0-4540 mg/kg), Ni (12.4-543 mg/kg), Pb (28.6-590 mg/kg), and Zn (51.3-324 mg/kg). The Pb-206/(207) Pb and Pb-208/Pb-207 ratios of the Pb-contaminated sediments of Lian-jiang (1.1787 +/- 0.0057 and 2.4531 +/- 0.0095, respectively) were lower than those of Nanyang River (1.1996 +/- 0.0059 and 2.4855 +/- 0.0082, respectively), indicating a significant input of non-indigenous Pb with low Pb-206/Pb-207 and Pb-208/Pb-207 ratios. Copper, Pb and Zn in the non-residual fractions noticeably increased in the contaminated sediments compared to those in the uncontaminated sediments. A genuine concern is associated with potential transport of the contaminated sediments downstream and enhanced solubility and mobility of trace metals in the non-residual fractions.
