OECD SIDS p-CRESOL 3. ENVIRONMENTAL FATE AND PATHWAYS ID: 106-44-5 DATE: 24.05.2004 for low OC soils could be attributed to H-bond interactions between phenolic hydroxyl and clay surfaces (clay-content in these soils: 68% and 86%). This type of adsorption can't be applied to explain the adsorption phenomenon (correlation between OC-content and adsorption), which usually occures in standard soils. Result : Koc = 3420 (Apison), 3350 (Fullerton), 115 (Dormont) Test condition : 3 soils tested: Dormont (pH 4.2; OC 1.2%), Apison (pH 4.5; OC 0.11%), Fullerton (pH 4.4; OC 0.05%) soil/water ratio 1:1 - 1:66 initial TS concentration 0.5 - 1.0 mg/l incubation period 24 h Reliability : (3) invalid No standard soil was used in the test. Soils Apison and Fullerton have a very low OC-content.Suggested OC-content in OECD 106:0.6-3.5%; in 67/548/EEC C.18: >0.3%) ). 10.05.2004 (36) Type : adsorption Media : water - soil Air : % (Fugacity Model Level I) Water : % (Fugacity Model Level I) Soil : % (Fugacity Model Level I) Biota : % (Fugacity Model Level II/III) Soil : % (Fugacity Model Level II/III) Method : Year : Remark : the authors cite a log Koc of 2,70 (koc 501), but no details on the experiments are described nor the primary citation is given Reliability : (4) not assignable secondary literature, experimental details missing 15.01.2003 (37) Type : adsorption Media : water - soil Air : % (Fugacity Model Level I) Water : % (Fugacity Model Level I) Soil : % (Fugacity Model Level I) Biota : % (Fugacity Model Level II/III) Soil : % (Fugacity Model Level II/III) Method : Year : Result : Neither Freundlich adsorption coefficients nor Koc values are reported in the article. The authors report the isotherms in graphic formate. In the Chemfate database citation of this article Freundlich adsorption coefficients (K) are estimated from the isotherms at about 50 ppm: 0.50 E02 to 0.5 E01. The corresponding Koc values can be calculated as 560 to 10000. No explanation for the wide variety of the adsorpion coefficients is given. Test condition : 5 soils were tested: Davidson (pH 6.4; OC 0.3%), Molokai (pH 6.2; 0.5%), Fanno (pH 7.0; OC 0.9%), Mohave (pH 7.8; OC 0.4%), Ava (pH 4.5; OC 0.4%) 200 ml deionized water were added to 10 g of soil initial TS concentration 5 - 100 ppm temperatur 22 °C equilibration time 5 days Reliability : (3) invalid UNEP PUBLICATIONS 203
