Establishment of a basis for administrative use of PestSurf

Table 6.6. Part of the result sheet generated by the PestSurf Excel sheet, applied to metamitron. The detection value used for generation of the table is 10 ng/l. Toxicity to fish, daphnies and algae are set to 100, 1000 and 10000 ng/, respectively. The recorded peaks are shown in Figure 6.11.
Tabel 6.6. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket anvendt på metamitron. Grænseværdien anvendt til tabelgenerering er 10 ng/l mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 100, 1000 og 10000 ng/l. De tabellerede hændelser er vist i Figur 6.11.
