Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
bioaccumulation in aquatic species: fish
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
other: Unsuitable test system (more than one substance tested in the same vessel). BCF for p-chloronitrobenzene cannot be derived with this test design; adopted according to OECD SIDS. The original source is available and has been reviewed.

Materials and methods

Principles of method if other than guideline:
Method: other: 30 fish exposed to 780+/-130 ng TS/L in a flow-through system; aceton used as solvent; samples of 6 fish each analysed at 5,12,20,28 and 36 days of exposure; duplicate water samples taken every 3 or 4 days; GC analysis
GLP compliance:
not specified

Results and discussion

Bioaccumulation factor
Type:
BCF
Value:
84 - 112

Any other information on results incl. tables

The BCF were determined for 5 incubation periods: 84 ± 8 for 5 days, 112 ± 23 for 12 days, 96 ± 14 for 20 days, 103 ± 16 for 28 days, and 108 ± 15 for 36 days. The mean BCF was 101 ± 18 with significant differences (p </= 0.05) among the sample intervalls. Since the higher chlorinated nitrobenzenes are possibly dechlorinated by metabolism in fish, a BCF for p-chloronitrobenzene cannot be derived with this test design.
