MCA is a weak acid (pKa = 2.86) under environmental conditions MCA
will occur in anionic or salt form e.g. sodium monochloroacetic acid
(SMCA). Therefore ecotoxicological data from both MCA and SMCA can be
used for hazard and risk assessment.
Based on the physicochemical properties (log Kow = -3.8,
solubility = 822 g/L), the substance is expected to have a very low
potential to adsorb to soil and sediment and will therefore stay in the
Also, due to the low log Kow SMCA does not have a potential to
The substance is readily biodegradable (aerobically as well as
anaerobically) and will therefore not persist in the environment.
