SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 - Pimephales promelas - 164 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 141 mg/L - 48 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 22.5 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge - > 100 mg/L - 3 h. Remarks:Respiration rate.
12.2 Persistence and degradability
AEROBIC: Hydroxyacetic acid achieved 32% theoretical oxidation by acclimated activated sludge after 12 hours of aeration(1). The theoretical BOD for hydroxyacetic acid was reported to be 0.89 after 5 days using acclimated mixed microbial cultures(2). Hydroxyacetic acid, present at 100 mg/L, reached 86% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(3). Therefore this compound is expected to biodegrade rapidly in the environment(SRC).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for hydroxyacetic acid (SRC), using a measured log Kow of -1.11(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
The Koc of hydroxyacetic acid is estimated as 0.14(SRC), using a measured log Kow of -1.11(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that hydroxyacetic acid is expected to have very high mobility in soil. The pKa of hydroxyacetic acid is 3.6(4), indicating that this compound will exist almost entirely in the anion form and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
12.5 Other adverse effects
no data available
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.
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.
