ECOTOXICITY ID: 793-24-8 DATE: 11.05.2005 Unit : mg/l EC50 : 420 Method : ISO 8192 "Test for inhibition of oxygen consumption by activated sludge" Year : 1984 GLP : no Test substance : other TS: technical grade 6PPD Reliability : (4) not assignable Original reference not available 04.11.2004 (55) 4.5.1 CHRONIC TOXICITY TO FISH 4.5.2 CHRONIC TOXICITY TO AQUATIC INVERTEBRATES 4.6.1 TOXICITY TO SEDIMENT DWELLING ORGANISMS 4.6.2 TOXICITY TO TERRESTRIAL PLANTS Species : Lactuca sativa (Dicotyledon) Endpoint : growth Exposure period : 14 day(s) Unit : mg/l EC50 : ca. .5 calculated Method : other: calculation Year : 1993 GLP : Test substance : other TS: various chloroanilines and other compounds, but not 6PPD Method : OECD Guide-line 208 was used to derive QSAR, which was used to calculate phytotoxicity of 6PPD. 6PPD was not measured. Remark : Lactuca sativa Ravel R2 Result : The 14 d EC50 of Lactuca sativa was measured for various chloroanilines and other compounds, but not with 6PPD. An equation for the calculation of the EC was derived (log EC50 = -0.46 log Kow + 2.38 [µmol/l]), which was used to calculate the EC50 of 6PPD (Log kow = 4.68) to be about 0.5 mg/l. Test condition : - 10 Seeds per tray. Trays covered with glass plates. Temperature 21 °C, photoperiod 16 h light / 8 h dark, light intensity 6500 lux, humidity 40 - 80 % - 6PPD was not tested but wide range of other chloroanilines and other compounds - The authors derived an equation for the QSAR for the relationship between log EC50 (µmol/l) and the log Kow: EC50 = -0.46 log Kow + 2.38 [µmol/l] - Using this equation (Log kow = 4.68), the EC50 was calculated to be about 0.5 mg/l Reliability : (2) valid with restrictions Accepted calculation method 05.11.2004 4.6.3 TOXICITY TO SOIL DWELLING ORGANISMS 88 UNEP PUBLICATIONS
