Persistence and degradability

AEROBIC: Metformin, added at 10 ug/g soil, exhibited biodegradation rates of 0.264. 0.231, and 0.118/day corresponding to half-lives of 5, 5 and 1 day, respectively, using three soil innocula - an alluvial agricultural soil (pH 6.6; 7.2% organic matter; 60.5% clay), loessy brown soil (pH 6.5; 6.5% organic matter; 47.4% clay), and a podsolic soil (pH 4.3; 3.9% organic matter; 28.2% clay), respectively, typical of Poland(1). However, the hydrochloride salt has been classified as not readily biodegradable(2). Metformin hydrochloride, present at 10 mg/L, exhibited 0.6% CO2 evolution in 28 days using a non-adapted, domestic sewage inoculum. In an aerobic aquatic system, 14C-labelled metformin hydrochloride dissipated from the water phase mainly through degradation and adsorption to sediment. The level of radioactivity in river water decreased over 56 days to 1.3% of applied metformin hydrochloride; 8.2% was present in the water phase after 100 days in a test pond system. The majority of radioactivity applied (81.5%) was found in the sediment(3).

Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for metformin(SRC), using an estimated log Kow of -2.64(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Koc values of 19, 16 and 12 were measured using an alluvial agricultural soil (pH 6.6; 7.2% organic matter; 60.5% clay), loessy brown soil (pH 6.5; 6.5% organic matter; 47.4% clay), and a podsolic soil (pH 4.3; 3.9% organic matter; 28.2% clay) typical of Poland(1). According to a classification scheme(2), this estimated Koc value suggests that metformin is expected to have very high mobility in soil.

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.
