Characterization of ecological risk. The sums of risk quotients (RQsum) are presented for different water resources including groundwater (GW: blue), canal water (CW: cyan), river water (RW: green) and drain water (DW: red). The boundaries of the central box are the 25th and 75th percentiles; the horizontal line is the median; and the whiskers of the boxplot represent the minimum and maximum values. The Red dashed line represents the threshold limit for the risk
