12.2 Persistence and degradability
AEROBIC: Dicyclopentadiene, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test (OECD 301C) which classified the compound as not readily biodegradable(1). Using OECD Guideline 301F (Ready Biodegradability: Manometric Respirometry Test) with an activated sludge inoculum, a petroleum-cracked stream containing 29% dicyclopentadiene had 0% biodegradation of the dicyclopentadiene fraction after 28 days(2). Very slow biotransformation of dicyclopentadiene was observed when it was inoculated with soil and water obtained from the Rocky Mountain Arsenal(3). Two field studies in Alberta, Canada found biodegradation rates of 37-57% in 266 days and not appreciable to 60% in 116 days(4).
12.3 Bioaccumulative potential
A BCF range of 58.9-384 was measured in fish for dicyclopentadiene using OECD method 305C and carp (Cyprinus carpio) which were exposed over an 8-week period(1). According to a classification scheme(3), this BCF range indicates that bioconcentration in aquatic organisms is moderate to high(SRC). A BCF of 53 was measured in bluegill fish (Lepomis macrochirus) using a concentration of 1 mg/L; however, a "disregarded study" flag was applied for environmental fate assessment as the exposure period was only 96 hours(4).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of dicyclopentadiene can be estimated to be 1500(SRC). According to a classification scheme(2), this estimated Koc value suggests that dicyclopentadiene is expected to have low mobility in soil.
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
