3. ENVIRONMENTAL FATE AND PATHWAYS ID: 106-44-5
DATE: 24.05.2004
No standard soil was used in the test. The five soils have a very low OCcontent
(0.3-0.9 %).Suggested OC-content in OECD 106:0.6-3.5%; in
67/548/EEC C.18: >0.3%)).
The isotherms are reported in five graphs, but the logarithmic scale is not
labeled correctly.
