In Georgia, there was a marked increase in both phosphate and nitrate concentration between 2004-2017. These increases were associated with sites in the Kura RBMU, where on average, phosphate concentrations were more than three times higher at the end of the time series, whilst nitrate concentrations doubled. Data from 2011-2013 should be treated with some caution, due to lower numbers of samples taken each year. This can explain the higher concentrations observed in these years. The concentrations for sites in the Black Sea RBMU have been fairly stable, with a slight decrease observed for nitrate.
