Table 1.4. 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. The lowest detection concentration is set to 1, while the toxicity values for fish, daphnies and algae are set to 10, 100 and 1000 ng/l, respectively.
Tabel 1.4. 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 mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 10, 100 og 1000 ng/l.
