Flocoumafen's production may result in its release to the environment through various waste streams; it's use as a rodenticide will result in its direct release to the environment. If released to air, a vapor pressure of 1.0×10-12 mm Hg at 25 deg C indicates flocoumafen will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase flocoumafen will be removed from the atmosphere by wet and dry deposition. If released to soil, flocoumafen is expected to have slight mobility based upon an estimated Koc of 4,100. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 7.3×10-13 atm-cu m/mole. If released into water, flocoumafen is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 400 suggests the potential for bioconcentration in aquatic organisms is high. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions.   

Usage: Rodenticide reported by D. J. Bowler et al. (Proc. Br. Crop Prot. Conf. - Pests Dis., 1984, 2, 397). Introduced by Shell International Chemical Co., Ltd (now BASF AG). Manufacturers: BASF. Biochemistry: Second-generation indirect anticoagulant. Inhibits the metabolism of vitamin K1, and thus depletes vitamin K1-dependent clotting factors in plasma. Blocks formation of prothrombin.

Application: Control of rodents including Mus musculus, Rattus norvegicus, R. rattus, Arvicanthis niloticus, Bandicota spp., Praomys natalensis, R. argentiventer, R. rattus diardii, R. losea, R. tiomanicus and Sigmodon hispidus. Effective against rodents which have become resistant to other anticoagulant rodenticides. In addition to use around buildings, it is effective in controlling rodents in field and plantation crops including cocoa, cotton, oilpalm, rice and sugar cane.
