Tsunemasa, Noritaka published the artcileEffects of Organoboron antifoulants on oyster and sea urchin embryo development, Application of Triphenyl(pyridin-1-ium-1-yl)borate, the publication is International Journal of Molecular Sciences (2013), 421-433, database is CAplus and MEDLINE.
Prohibition of Ot (organotin) compounds was introduced in Japan in 1997 and worldwide from Sept. 2008. This meant that the production of paints containing TBT compounds was stopped and alternatives to the available Ot antifoulants had to be developed. It has been claimed that the degradation byproducts of these alternative antifoulants were less toxic than those of Ot compounds Since the introduction of the alternative antifoulants, the accumulation of these compounds has been reported in many countries. However, the toxicity of these compounds was still largely unreported. Here, the toxicity of the alternative Ot antifoulants TPBP (triphenylborane pyridine) and TPBOA (triphenylborane octadecylamine) and their degradation products on Crassostrea gigas and Hemicentrotus pulcherrimus were tested. The results showed that toxic effects in C. gigas was higher for each antifouling biocide than that in Hemicentrotus pulcherrimus. Also, while the toxicity of the Organoboron antifoulants and the Ots were the same, the former’s degradation products were much less harmful.
