Abstract Tabulations are given for total dissolved trace metal concentrations in the Var and the Roya, two rivers containing relatively little pollution, which enter the North Mediterranean. Means and standard deviations were as follows. For the Var Cu was 240 ± 140 ng L−1, Zn 122 ± 16 ng L−1, Cd 30.7 ± 4.9 ng L−1, and Pb 111 ± 68 ng L−1. For the Roya corresponding values were Cu 284 ± 98 ng L−1, Zn 87 ± 14 ng L−1, Cd 74 ± 57 ng L−1, and Pb 80 ± 48 ng L−1, These values are lower than expected from stuidies reported in the literature, but probably are explained by the limestone environment. Values are also tabulated for the content in the suspended matter and sediments. The Var and the Roya differed in the amount of complexed metals, the percentage being much higher for the Roya. These regional background results are important for assessment of possible pollution in future.
