Description of key information
The acute fish toxicity studies of FAT 20028 were performed with trout and zebra fish. In a key study, LC50of FAT 20028/B in trout fish was 8 mg/L. The 48 h EC50 to daphnia study was 75.3 mg test substance/l (95 % conf. limits: 46.0 - 123.1 mg test substance/l). The influence of FAT 20028/E on the growth of the freshwater plant Lemna gibba was assessed in a semi-static dose-response test. The 7-day EyC50was calculated to be 1.11 and >1.98 mg test item/L for frond number and dry weight, respectively. The 7-day ErC50was calculated to be >1.98 and >1.98 mg test item/L for frond number and dry weight, respectively. The 7-day NOEyC and the LOEyC were determined to be 0.080 and 0.241 mg test item/L for frond number and 0.241 and 0.706 mg test item/L for dry weight, respectively. The 7-day NOErC and the LOErC were determined to be 0.080 and 0.241 mg test item/L for frond number and 0.241 and 0.706 mg test item/L for dry weight, respectively. Few studies with different batches of FAT 20028 were carried out to determine the toxicity to microorganisms. Based on the key study the IC50(3 h) of FAT - 20'028/B was 300 mg/l
