SECTION 12: Ecological information

12.1 Toxicity

Toxicity to fish: LC50 - Leuciscus idus - 37 mg/L - 96 h.
Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 0.4 mg/L - 48 h.
Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - 19 mg/L - 72 h.
Toxicity to microorganisms: EC50 - Pseudomonas putida - 125 mg/L - 17 h.

12.2 Persistence and degradability

ANAEROBIC: 2-Mercaptoethanol, was shown to be biomineralized under methanogenic conditions(1). 2-Mercaptoethanol, present at 100 mg/L reached 29% biodegradation in 55 days using 120 mL flasks containing sludge from an upflow anaerobic blanket reactor treating liquid hen manure at 1 g volatile suspended solids (VSS)/L, 0.4 g Chemical Oxygen Demand (COD), basal medium, and incubated at 30 deg C(1). Therefore, this compound is not expected to biodegrade rapidly under anaerobic conditions(SRC). Addition of cosubstrates, glucose or a combination of propionic or butyric acids, did not affect the rate of degradation(1). The compound is moderately toxic to microorganisms(1).

12.3 Bioaccumulative potential

An estimated BCF of 3.0 was calculated for 2-mercaptoethanol(SRC), using an estimated log Kow of -0.20(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 2-mercaptoethanol can be estimated to be 1.3(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-mercaptoethanol is expected to have very high mobility in soil.

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.
