Additional information

Data are from representative river stations. Stations that have no designation of type are assumed to be representative and are included in the analysis. Time series trends have been calculated using only stations that have recorded concentrations for at least 4 of the years included in the time series. Sen´s Test then applied to determine statistically significant trends in the data (see Methodology section for further details).
