SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 Salmo gairdneri (Rainbow trout) 19 ppm/96 hr /Conditions of bioassay not specified/ /Technical eptam
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
AEROBIC: Radio-labeled eptam (initial concn of 2 ppm) was incubated at 25 deg C and pH 5.3 in sludge- and manure-amended soils; after a 60 day test period, 65-66 and 62-65% 14C-carbon dioxide evolution was observed, respectively(1). In a heavy silt loam, heavy silt and fine sandy loam which all had 3-4 yrs previous exposure to eptam, about 100% (initial concn not given) degradation was observed after 12-15 days. In the same time period, about 10-20% loss of eptam was noted in sterile soil samples(2); this may have been due to volatilization. In a heavy silt loam, heavy silt and fine sandy loam which had no previous exposure to eptam, about 100%, 20% and 20% (initial concn not given) degradation was observed after 12, 15 and 15 days, respectively(2). In a sandy loam soil (pH 6) incubated at 28 deg C, 93% and 68% carbon dioxide production was observed after 30 days for concns of 150 and 1500 ppm eptam(3). Laboratory tests to measure the aerobic soil degradation rates of eptam indicated half-lives of 36 to 75 days(4). The rate of eptam degradation decreases with time(4).
Bioaccumulative potential
The bioaccumulation and elimination of 14C-EPTC by bluegill sunfish was investigated in a dynamic flow-through system, where the fish were exposed for 28 days to radiolabeled 14C-eptam at 22 deg C, followed by depuration in EPTC free water for 14 days(1). Bioconcentration factors were 37, 60, and 110, respectively, in the edible, whole fish, and non-edible fish tissues(1). According to a classification scheme(2), the whole-fish BCF value suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
The avg Koc of eptam is 200; and measured values of Koc range from 170-280(1). Experimentally-determined Kocs are: 283 in soil with 1.0-4.5% organic content and 109 in soil with 30% organic content(2). Koc values for eptam were measured for 4 soil series with various organic matter (OM%) levels(1): e.g., Atterberry (2.2%), Columbia (1.1%), Keeton (0.3%), and Sorrento (1.8%); the Koc values were 136, 146, 264, and 143, respectively(3). According to a classification scheme(4), these Koc values suggest that eptam is expected to have moderate to high mobility in soil(SRC). Eptam has low affinity for binding to soil suggesting a potential to leach to groundwater(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
