| Research Abstract |
The fate of pharmaceuticals and polycyclic aromatic hydrocarbons (PAHs) in water environments and in treatment processes were investigated focusing on the separate estimation of adsorption and biodegradation. The significant contribution of co-metabolism in the degradation of pharmaceuticals durintg nitrification was observed in an mixed culture system. The degradation spectrum for hparmaceuticals by fungi was quite different from that by activated sludge. The continuous operation of a granular activated carbon reactor showed a considerable adsorption capacity for ionic pharmaceuticals. A model calculation in Nagoya Bay based on be experiments of adsorption and degradation showed that the half amount of PAH loading to the bay remained in the bay without biodegradation in the sediments, while the residual half was transported outside the bay by the tidal exchange.
