Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
6.3 Methods and materials for containment and cleaning up
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: LC50; Species: Daphnia magna (Water flea, neonate); Conditions: freshwater, renewal, 20 deg C, pH 8.2, hard water, dissolved oxygen 8.6 mg/L; Concentration: 310 ug/L for 48 hr (95% confidence interval: 210-470 ug/L)

12.2 Persistence and degradability
The potential of microbes from the rhizosphere of bulrush plants (Scirpus robustus), and bulk soil to volatilize selenomethionine was studied in liquid cultures under controlled conditions; in the absence of added carbon, selenium volatilization was greatest from selenomethionine, as compared to selenite and selanate.
12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated in fish for selenium methionine(SRC), using an estimated log Kow of -3.0(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of selenium methionine can be estimated to be 8.7(SRC). According to a classification scheme(2), this estimated Koc value suggests that selenium methionine is expected to have very high mobility in soil.

SECTION 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.
