EC number: 942-710-1
CAS number: -
The 0% of control
organisms were immobilised and the dissolved oxygen concentration at the
end of the test was 9.1-9.2 mg O2/L. The initial pH measurements did not
differ from the final measurements by more than 1.5 units in each test.
The color of the test solutions remained the same throughout the test.

This test using the
procedures outlined in the Maxxam Study Plan for TOX1522 which is based
on the SOP for the OECD 202 (BBY2SOP-00017) and OECD 202 (OECD, 2004).
The results of this OECD 202 test for CJ302 show that all validity
criteria were met.
Based on the nominal
concentrations of CJ302:
48-hr EC50 was >100 mg/L.
NOEC and LOEC was 100 mg/L and >100 mg/L, respectively.
The 48-hr EC50 of CJ302
was >100 mg/L for Daphnia magna (OECD TG202).
The test was considered
valid as 0% of control organisms were immobilised and the minimum
dissolved oxygen concentration at the end of the test was 9.1-9.2 mg
O2/L. All test validity criteria were met. The pH of the test solutions
was within the ranges outlined in the OECD 202 test guideline. The
measured concentrations of CJ302 were within 80-120% of their nominal
1. The 48-hr EC50
was >100 mg/L.
2. The NOEC and
LOEC was 100 mg/L and >100 mg/L, respectively.
