Establishment of a basis for administrative use of PestSurf

Table 5.12. Part of the result sheet generated by the PestSurf Excel sheet. The 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 5.25.
Tabel 5.12. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket. Detektionsgrænsen er sat til 1 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 10, 100 og 1000 ng/l. De tabellerede hændelser er vist i Figur 5.25.
