Particulate and dissolved trace metals in Lake Ontario
Particulate metal concentrations in the nearshore waters of Lake Ontario have been determined to be 690 ng l −1 for Cu; 40 ng l −1 for Cd; 180 ng l −1 for Ni; 1690 ng l −1 for Zn; 2100 ng l −1 for Mn; and 700 μg l −1 for Fe. These values are considerably higher than the particulate metal concentrati...

| description | Particulate metal concentrations in the nearshore waters of Lake Ontario have been determined to be 690 ng l
−1 for Cu; 40 ng l
−1 for Cd; 180 ng l
−1 for Ni; 1690 ng l
−1 for Zn; 2100 ng l
−1 for Mn; and 700 μg l
−1 for Fe. These values are considerably higher than the particulate metal concentrations in the offshore waters: 130, 8, 34, 230, 110, 260 and 9000 ng l
−1 for Cu, Cd, Ni, Zn, Pb, Mn and Fe respectively. In general, 50–80% of the Cu, 10–40% of the Ni, 20–60% of the Cd and >60% of the Pb in the lake water were bound to the suspended particulates. From the standing crop of the particulate metals and the estimated rates of their deposition on the lake bottom, the residence times of the particulate metals in the lake water column have been estimated to be about 0.5 yr. on the average. The suggestion is made that particulate organic matter may be an important vehicle for metal transport to the Lake Ontario sediments. |
