The registrant is currently undertaking registration studies with the
test item EXP0700332, and have requested Charles River determine the
adsorption coefficient. This study meets the requirements of the OECD
Guidelines for the testing of chemicals, OECD 121. A summary of the
findings is presented below:
During testing it was observed that these hydrocarbon structures did not
elute from a cyanopropyl solid phase HPLC column during the 45 minute
run time. The adsorption coefficient of duplicate determinations of
EXP0700332 test item was therefore determined to be as follows:
Log10 Koc of EXP0700332 >10.04 (retention time greater than 45 minutes
Koc of EXP0700332 >1.10 x 1010
Alternatively, the adsorption coefficient may be expressed as being
greater than that of 4,4’-DDT, the latest eluting reference standard
used. Since 4,4’-DDT has a theoretical adsorption coefficient of 5.63,
it may be stated that for EXP0700332:
Log10 Koc >5.63
Koc >4.27 x 105
During testing, it was observed that these hydrocarbon structures did
not elute from a cyanopropyl solid phase HPLC column during the 45
minute run time. The adsorption coefficient of duplicate determinations
of EXP0700332 test item was therefore determined to be as follows:
Koc of EXP0700332 >1.10 x 10^10
