Cypermethrin (95 th percentile (P 95 ) = 5.09E -01 ); a substance that produces only NCeffects, but it is below the limit value. As shown in the table, not even substancesthat have both types <strong>of</strong> effects are close to the threshold value.Table 5 also shows the biological risk values. In this case, only one substanceexceeds the threshold value, and it is again Cypermethrin (P 95 = 1.36E +01 ). <strong>The</strong> P 95<strong>of</strong> the risk to Daphnia sp. is 17.10 and 20.91 for Cyprinus sp. This high value leadsto a higher value <strong>of</strong> Biota + Human Risk, as shown in Table 6, where Cypermethrinhas a value <strong>of</strong> 1.41E +01 . <strong>The</strong> remaining substances are from 3 (Heptachlor,Chloropyrifos, α-HCH, 2.4-D and Acetochlor) to 7 orders <strong>of</strong> magnitude(Endosulfan) below the value <strong>of</strong> Cypermethrin.Table 5.
