SECTION 12: Ecological information

12.1Toxicity

• Toxicity to fish: LC50 Species: /Oncorhynchus mykiss/ (Rainbow trout); Concentration: 1,020 mg/L for 96 hr /Conditions of bioassay not specified in source examined
• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2Persistence and degradability

AEROBIC: Using a mixed microbial consortia enriched from untreated sewage samples collected in the vicinity of a primary treatment plant in Delhi, India, L-ascorbic acid exhibited 36.7 mg/L BOD, suggesting moderate susceptibility to biodegradation(1).

12.3Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for L-ascorbic acid(SRC), using a log Kow of -1.85(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).

12.4Mobility in soil

The Koc of L-ascorbic acid is estimated as 10(SRC), using a log Kow of -1.85(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that L-ascorbic acid is expected to have very high mobility in soil. The pKa of L-ascorbic acid is 4.70(4), indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

12.5Other adverse effects

no data available

SECTION 13: Disposal considerations

13.1Disposal 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.
