Table 2.4. Part of the result sheet generated by the PestSurf Excel sheet. The selected table shows the pre-defined point along the stream with the highest concentration recorded. Lowest detection value is set to 100 ng/l, toxicity to fish, daphnies and algae are set to 200, 400 and 1000 ng/, respectively. The recorded peaks can be seen in Figure 2.9.
Tabel 2.4. 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 1 ng/l mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 200, 400 og 1000 ng/l. De viste hændelser kan ses i Figur 2.9.
