Establishment of a basis for administrative use of PestSurf

Table 3.15. Part of the result sheet generated by the PestSurf Excel sheet for the upstream part of the sandy loam catchment for the autumn application of bromoxynil. The limiting values applied in the simulation is lowest detection valuε = 10 ng/l, toxicity to fish, daphnies and algae are set to 100, 1000 and 5000 ng/, respectively. The recorded peaks are shown in Figure 3.39.
Tabel 3.15. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for den opstrøms del af morænelersoplandet for efterårsudbragt bromoxynil. Grænseværdien anvendt ved tabelgenerering er detektionsgrænsen: 10 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 100, 1000 og 5000 ng/l. Hændelserne er vist i Figur 3.39.
