Establishment of a basis for administrative use of PestSurf

Table 3.19. Part of the result sheet generated by the PestSurf Excel sheet for autumn- applied bromoxynil. The limiting values applied in the simulation is lowest detection valuε = 1 ng/l, toxicity to fish, daphnies and algae are set to 10, 100 and 1000 ng/, respectively. The recorded peaks are shown in Figure 3.49.
Tabel 3.19. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for efterårsudbragt bromoxynil. Grænseværdien anvendt i tabellen er detektionsgrænsen, 1 ng/l mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 10, 100 og 1000 ng/l. De tabellerede hændelser er vist i Figur 3.49.
