Establishment of a basis for administrative use of PestSurf

Table 3.18. Part of the result sheet generated by the PestSurf Excel sheet for spring application of bromoxynil. The limiting values applied in the table 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 3.48.
Tabel 3.18. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for forårsudbragt 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 3.48.
