Results and discussion
Any other information on results incl. tables
Divinylbenzene-55 test material 5, 10 and 20 day BOD's are 0.08, 0.24 and 0.38 parts/part, respectively.
The Pollutional Evaluation of Compounds is a summary of data that can be used to assess certain environmental properties of compounds or formulations evaluated by the Michigan Division Waste Control Laboratory and since September, 1974, by Environmental Sciences Research. This summary has been compiled from data sheets on file in the above laboratories. Some of the data, especially that relating to biodegradability and fish toxicity, is best interpreted with knowledge of the special test conditions and/or additional observations made during the test.
Applicant's summary and conclusion
- Conclusions:
- Divinylbenzene-55 test material 5, 10 and 20 day BOD's are 0.08, 0.24 and 0.38 parts/part, respectively.
- Executive summary:
Screening tests were run on a sample of divinylbenzene-55 (DVB-55) and the following conclusions may be made:
Movement - Water solubility is 44 mg/L and the vapour pressure is 1.0 mm Hg at 33°C. Removal after 1 hour aeration was 96% by sensitive dichromate analysis and 100% after 4 hours.
Stability - DBV-55 does not consume oxygen in the standard 20-day BOD test and will probably not degrade in a biological wastewater treatment plant.
Bioconcentration - DVB-55 has a predicted bioconcentration factor (BCF) of 184 which may be contrasted with PCB which has a BCF of 10000 or more. The persistence of DVB-55 in the aquatic environment is unknown.
Fish toxicity - DVB-55 showed 96-hr LC10, LC50, and LC90 values of 6.6 (4.4-7.2)*, 7.5 (6.5-8.1) , and 8.6 (8.1-10.8) mg/L, respectively, to fathead minnows, Pimephales promelas Raf inesque, in static water tests.
