Table 10.4. Part of the result sheet generated by the PestSurf Excel sheet. The selected table shows the point along the stream with the highest concentration recorded. The lowest detection value is 0.5 ng/l, toxicity to fish, daphnies and algae are set to 1, 10 and 100 ng/l, respectively. The recorded peaks are shown in Figure 10.9.
Tabel 10.4. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket. Den udvalgte tabel viser det fordefinerede punkt langs med åen med højest koncentration. Detektionsgrænsen er sat til 0.5 ng/l mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 1, 10 og 100 ng/l. De tabellerede hændelser er vist i Figur 10.9.
