under static conditions
over a period of 48 hours from 2009-09-16 to 2009-09-18 at Dr. U.
Käthe-Paulus-Str. 1, D-31 157 Sarstedt, Germany.
20 test organisms were exposed to the limit concentration and the
control. The limit
concentration and the control were analysed via HPLC in the fresh media
(0 hours) and in the
old media (48 hours). Details of the analytical method are given in part
9. The recoveries of the
test item in the limit concentration were 102 % of the nominal value in
the fresh media at test
start (0 hours) and 100 % of the nominal value in the old media at test
end (48 hours). All effect
values given are based on the nominal test item concentration (Table 1).
