Mieno, Hirohisa published the artcileToxic effects of alternative antifouling biocides on marine zooplankton and phytoplankton, COA of Formula: C23H20BN, the publication is Yosui to Haisui (2004), 46(12), 1031-1036, database is CAplus.
The toxic effects of antifouling biocides as alternatives of TBT, TBTO and the like on marine zooplankton and phytoplankton were assessed; the used biocides were Irgarol 1051, Diuron, Sea-Nine 211, Zinc pyrithione, Copper pyrithione, Tri-Ph borane pyridine (KH101). Zinc di-Me dithiocarbamate and N-(2,4,6-trichlorophenyl)maleimide (TCPM); in addition, Cu2+, Cr6+, Zn2+, Cd2+ and DMSO were examd; the used phytoplankton were Skeletonema costatum (NIES-323) and the used zooplankton were Artemia saline. The bioassay examination for the phytoplankton were performed based on the ISO 10253 (1995) method; for the zooplankton, Artoxkit M (Microbiotest corporation) with a microplate was used. Values of NOEC and 72-h EC50 for S. costatum, and 48-h LC10 and 48-h LC50 for A. salina were determined for each of the biocides, and metals also. The values of 72-h EC50 were 0.85-21 μg/L; the ones of 48-h LC50 were 28-7400 μg/L. The biocides showed higher sensitivities than the metals. The risk assessment in the maline environment also was tried based on the obtained data and published data for the highest concentrations of the residual biocides in maline water (HCRB) in references; the assessment were relied on risk coefficients determined in an equation: risk coefficient = (HCRB)/(NOEC or LOEC). The values of NOEC and LOEC were discussed of many countries.
