Establishment of a basis for administrative use of PestSurf

Table 11.9. Part of the result sheet generated by the PestSurf Excel sheet for the upstream part of the sandy loam catchment. The lowest detection value for table generation is 100 ng/l, toxicity to fish, daphnies and algae are set to 1000, 10000 and 100000 ng/, respectively. The recorded peaks are shown in Figure 11.26.
Tabel 11.9. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for den opstrøms del af morænelersoplandet. Detektionsgrænsen for tabelgenerering er sat til 100 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 1000, 10000 og 100000 ng/l. Hændelserne er vist i Figur 11.26.
