Establishment of a basis for administrative use of PestSurf

Table 7.14. Part of the result sheet generated by the PestSurf Excel sheet for the downstream part of the sandy loam catchment for the spring application of pendimethalin. The limiting values is set to 5 ng/l, toxicity to fish, daphnies and algae are set to 10, 100 and 1000 ng/, respectively. The recorded peaks are shown in Figure 7.43.
Tabel 7.14. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for den nedstrøms del af morænelersoplandet for forårsudbringningen af pendimethalin. Detektionsgrænsen for tabelgenerering er sat til 5 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 10, 100 og 1000 ng/l. Hændelserne er vist i Figur 7.43.
