Appendix

In this section, a table showing all basic information about sampling points is presented. The original names that all the Hydrographical Confederations and Water Agencies give to the samples are showed in column 2. The river and town where sediments are sampled is showed in column 4. Numerical values of all variables are expressed as originally reported by each Confederation or Water Agency. For simplicity, only concentrations of total PAHs are showed. They were calculated as the sum of 8 individual PAH concentrations (further details are given in the main text). When any individual PAH concentration was reported under their method detection limit, half the detection limit was used.

Table A.1Basic information about sampling points as well as all analytical data collected. All trace element concentrations are expressed in mg/kg dw. Total PAH concentrations are expressed in μg/kg dw
