Establishment of a basis for administrative use of PestSurf

Table 5.6. Part of the result sheet generated by the PestSurf Excel sheet, applied to malathion. The limiting values applied for table generation is 1 ng/l, toxicity to fish, daphnies and algae are set to 10, 50 and 100 ng/, respectively. The recorded peaks are shown in Figure 5.10.
Tabel 5.6. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket anvendt på malathion. Grænseværdien anvendt til tabelgenerering er sat til 1 ng/l mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 10, 50 og 100 ng/l. De tabellerede hændelser er vist i Figur 5.10.
