Establishment of a basis for administrative use of PestSurf

Table 9.6. Part of the result sheet generated by the PestSurf Excel sheet, applied to prosulfocarb. The detection value used for generation of the table is 1 ng/l. The toxicity values were set to 10,100 and 1000 ng/l, respectively. The recorded peaks are shown in Figure 9.14.
Tabel 9.6. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket. Grænseværdien anvendt til tabelgenerering er sat til 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 9.14.
