Table 7.6. Part of the result sheet generated by the PestSurf Excel sheet for pendimethalin application during autumn. The selected table shows the point along the stream with the highest concentration recorded. The lowest detection value is 10 ng/l, toxicity to fish, daphnies and algae are set to 100, 1000 and 10000 ng/, respectively. The recorded peaks are shown in Figure 7.14.
Tabel 7.6. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for efterårsudbragt pendimethalin. Den udvalgte tabel viser det fordefinerede punkt langs med åen med højest koncentration. Detektionsgrænsen er sat til 10 mens toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 100, 1000 og 10000 ng/l. De tabellerede hændelser er vist i Figur 7.14.
