抄録: The physico-chemical characterization, distribution, degradation and cross media partitioning in aquatic environment of eight species of booster biocides were reviewed. The physico-chemical characterizations of these booster biocides varied. Generally, low water/sediment partitioning, low bioconcentration factor and non volatilization were assumed from physico-chemical properties. The survey of booster biocides were carried out in somewhere of the world. Sea-Nine 211, Diuron, Irgarol 1051, Chlorothalonil and Dichlofluanid in water were detected in the range of <0.001-3.7μgl^<-1>, <0.0007-6.742μgl^<-1>, <0.001-1.7μgl^<-1>, <0.001-1.38μgl^<-1> and <0.001-0.76μgl^<-1>, respectively. Concentrations of Sea-Nine 211, Diuron, Irgarol 1051, Chlorothalonil and Dichlofluanid in sediment ranged of <0.1-2.35μgkg^<-1>dry, <0.1-1350μgkg^<-1>dry, 0.007-222.3μgkg^<-1>dry, <0.1-46.5μgkg^<-1>dry and <0.1-688.2μgkg^<-1>dry, respectively. While, there are no report concerning of Copper pyrithione, Zinc pyrithione and Pyridine triphenylboron. Sea-Nine 211, Dichlofluanid, Copper pyrithione, Zinc pyrithione and Pyridine triphenyl boron were degraded easily by sunlight and bacteria. Further Copper pyrithione, Zinc pyrithione and Pyridine triphenyl boron were hydrolyzed in seawater. As a consequence, these compounds therefore produced various degradation products.
