Persistence and degradability

AEROBIC: The biodegradation of L-aspartic acid was measured in several BOD5 tests. After 5 days, 48.5%(1) 38.7(2) and 80.5%(3) of the theoretical BOD was reached using a sewage inoculum. L-Aspartic acid was degraded by 81% BODT after 30 days using a sewage inoculum(4). In a second Warburg test using an activated sludge inoculum, 8.9, 16.2, and 28.8% BODT was reached after 0.25, 0.5, and 1 day, respectively(5). DL-Aspartic acid was rapidly degraded by 98 to >99% in a laboratory-scale activated sludge unit at initial concentrations of 599, 1198, 2396, and 4792 mg/L and average detention times of 20.5, 29, 42, and 85 hours, respectively(6). Samples of marine water from the Scheldt estuary, the Belgian coastal zone of the North Sea, and the English Channel were incubated with 14C-labeled DL-aspartic acid and relative rates of total utilization (incorporation plus respiration) of 2.7, 1.5, and 0.10%/hr, respectively, were measured over a 4-hour period(7). Based on these data, L-aspartic acid is expected to biodegrade rapidly.

Bioaccumulative potential

An estimated BCF of 0.7 was calculated in fish for L-aspartic acid(SRC), using a water solubility of 5,360 mg/L(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).

Mobility in soil

The Koc of L-aspartic acid is estimated as 39(SRC), using a water solubility of 5,360 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that L-aspartic acid is expected to have very high mobility in soil. However, L-aspartic acid has pKa values of 1.92, 3.87, and 9.87(5), indicating that this compound will exist as a zwitterion in the environment. In H(Al) montmorillonite, aspartic acid showed an L-2 type adsorption isotherm with an initial preferential sorption when compared with the solvent or other solutes followed by a decrease in sorption as more solute was sorbed(4).

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
