Description of key information

Biodegradation of vinylbenzyl chloride failed to exceed the 60% pass criterion for demonstrating "ready biodegradability" in the manometric respirometry test (KS_ Manometric Respirometry Test_2017). The results of this test, therefore, demonstrate that vinylbenzyl chloride cannot be classified as "readily biodegradable," according to the OECD 301F: Manometric Respirometry Test (OECD, 1992).

This conclusion is supported by measurement of the oxygen demand as an indication of biodegradability. Using effluent from general wastewater treatment as the seed, a biochemical oxygen demand of 0.16 and 0.58 pts/pt (parts of oxygen demand per part of vinylbenzyl chloride) was determined after 5 and 10 days, respectively. The total oxygen demand was found to be 2.54 (pts/pt). 5% of the compound were removed after 4 hours of aeration (other information_oxygen demand_1975).
