Anti-fouling agents are usually applied to ship hulls to prevent worsening of fuel consumption rates resulting from the buildup of marine organisms, such as barnacles and bivalves, which become attached to the surfaces of ship hulls. Triphenylborane compounds (TPBP, TPBOA, OPA) are popular antifouling agents mainly used in Japan, but there is little information available on its fate and ecotoxicity in aquatic environments. The purpose of this study was to evaluate the effects of light on the fate of three triphenylborane compounds in water. The solutions containing triphenylborane compound irradiated with white fluorescent lamp for up to 48 h were subjected for chem. anal. of triphenylborane compounds and its degradation products and for ecotoxicity assessment to marine photo bacteria Aliivibrio fischeri and crustacean Artemia salina. TPBOA and OPA were quant. analyzed as TPBP with adding excess amount pyridine. Triphenylborane compounds in 2% sodium chloride solution and artificial seawater were degraded with irradiation of white fluorescent lamp. The 30-min EC50 values of the triphenylborane compounds for photo bacteria were ranging in 0.27 â?1.0 and the 48-h LC50 values of them for crustacean were ranging in 0.079 â?0.26 μ M, resp. Crustacean was more susceptible to triphenylborane compounds than photo bacteria. Ecotoxicity of the solution was reduced by irradiation of white fluorescent lamp. Crustacean lethality by triphenylborane compounds was well expressed with the concentration after exposure regardless of the treatments. It was suggested that unknown products, might have produced, had less ecotoxicity.
