Methodenlisting

Auswertung (Statistische Methode) Raw daphnid survival data sets were analyzed by Fisher's Exact test. Arcsine square root transformations were made on all ether survival and hatching success raw data before further data analvxys were performed. With the exception of the daphnid survival data, all data (both transformed and raw data) were then subjected to a chi-square test of normality and Bartlett's test for homogeneity of variance.

Memos

Bemerkung The chronic toxicity to Ceriodaphnia was determined by the method given in Draft No. 3 of the ASTM proposed guide for conducting three brood, renewal toxicity tests (Waller and Lazorchak, 1986).
