12.1 Toxicity
LD50; Species: Apis mellifera (Honey Bee) adult; topical >25.4 ug/bee
Gentamicin's production and administration as a veterinary and human medication may result in its release to the environment through various waste streams. Gentamicin is derived from Micromonospora species. If released to air, an estimated vapor pressure of 1.8X10-13 mm Hg at 25 °C indicates gentamicin will exist solely in the particulate phase in the atmosphere. Particulate-phase gentamicin will be removed from the atmosphere by wet and dry deposition. Gentamicin does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. If released to soil, gentamicin is expected to have very high mobility based upon an estimated Koc of 10. The estimated pKb of gentamicin is 9.0, indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 9.8X10-31 atm-cu m/mole. Gentamicin is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data in soil or water were not available. If released into water, gentamicin is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from
