Additional information on environmental fate and behaviour
Administrative data
- Endpoint:
- additional information on environmental fate and behaviour
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Genrerally a state of the art (Q)SAR screening in substance registry lists (DSL, TSCA) used to compile P&B potential substances identifiable and/or identified in environmental probes - but with regard to DCDPS the QSAR models deliver values at variance in orders of magnitude to experimental data.
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6

Results and discussion

610 chemicals were identified that might be persistent and bioaccumulative (P&B) and that were not being considered incurrent Great Lakes, North American, and Arctic contaminant measurement programs.
Applicant's summary and conclusion
- Conclusions:
- DCDPS is listed as example of High Priority Chemical with Persistence and Bioaccumulation Potential.
- Executive summary:
The goal of this study was to identify commercial chemicals that might be persistent and bioaccumulative (P&B) and that were not being considered incurrent, North American, and Arctic contaminant measurement programs. The authors combined the Canadian Domestic Substance List (DSL), a list of 3059 substances of “unknown or variable composition complex reaction products and biological materials” (UVCBs), and the U.S. Environmental Protection Agency (U.S. EPA) Toxic Substances Control Act (TSCA) Inventory Update Rule (IUR) database for years 1986, 1990, 1994, 1998, 2002, and 2006 yielding a database of 22263 commercial chemicals. From that list, 610 chemicals were identified by estimates from U.S EPA EPI Suite software and using expert judgment. This study has yielded some chemicals considered interesting and probable P&B compounds that are pointed out for further study.
Recent studies confirming the presence of many of these chemicals in the environment are cited. Among these DCDPS is included despite a relatively low predicted BCF.
The following calculated values of DCDPS are reported: Atmospheric dissipation half life time DT50, log Kaw, log Kow, log Koa, and BCF. While the calculation of the atmospheric DT50 seems to be erring (see executive summary of the weight of evidence entry in section 5.1.1) and the estimated BCF is higher than the experimentally determined one (NITE 2002, section 5.3.1), the Log Kowis exactly in line with the experimental value (Boelhouwers 2006, section 4.7). Log Kawand are derived using a calculated vapour pressure / Henry constant and thus slightly different from the ones calculated on the basis of the experimental values (see Endpoint Summary of section 5.4).
