Establishment of a basis for administrative use of PestSurf

Table 7.16. Part of the result sheet generated by the PestSurf Excel sheet for the downstream part of the sandy loam catchment for the autumn application of pendimethalin. The limiting values is set to 25 ng/l, toxicity to fish, daphnies and algae are set to 100, 1000 and 10000 ng/, respectively. The recorded peaks are shown in Figure 7.45.
Tabel 7.16. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for den nedstrøms del af morænelersoplandet for efterårsudbringningen af pendimethalin. Detektionsgrænsen for tabelgenerering er sat til 25 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 100, 1000 og 10000 ng/l. Hændelserne er vist i Figur 7.45.
