Partitioning behavior of the antifouling booster biocide, Irgarol-1051 (2-methythio-4-tert-butylamino-6-cyclopropylamino-s-triazine), its production by-product, M3, and its environmental transformation products, M1 and M2, were studied. Octanol-water partition coefficients, log K(OW), and organic matter-water partition coefficients, log K(OC), of these s-triazines were measured by reversed-phase HPLC and a triphasic SPME equilibrium model, respectively. The average log K(OW) (+/-SD) of the four s-triazine species were: 4.39+/-0.07 (M3); 3.38+/-0.12 (Irgarol-1051); 2.92+/-0.12 (M2) and 2.54+/-0.11 (M1), while mean log K(OC) (+/-SD) of these species were: 2.47+/-0.03 (M3); 2.16+/-0.03 (Irgarol-1051); 1.97+/-0.03 (M2) and 1.79+/-0.04 (M1). These results were compared to reported physicochemical parameters of Irgarol-1051 in the literature. Partitioning behavior of these s-triazine species in the coastal environment revealed by their K(OW) and K(OC) were also discussed.
研究了防污增效杀生剂2-甲硫基-4-叔丁氨基-6-环丙氨基-s-三嗪（Irgarol-1051）、其生产副产物M3及其环境转化产物M1和M2的分配行为。分别采用反相高效液相色谱法和三相固相微萃取平衡模型测定了这些s-三嗪的正辛醇-水分配系数log K(OW)和有机碳-水分配系数log K(OC)。这四种s-三嗪的平均log K(OW)（±标准差）分别为：4.39±0.07（M3）；3.38±0.12（Irgarol-1051）；2.92±0.12（M2）和2.54±0.11（M1），而这些物质的平均log K(OC)（±标准差）分别为：2.47±0.03（M3）；2.16±0.03（Irgarol-1051）；1.97±0.03（M2）和1.79±0.04（M1）。将这些结果与文献中报道的Irgarol-1051的理化参数进行了比较。还讨论了这些s-三嗪在沿海环境中的分配行为，其K(OW)和K(OC)揭示了这一点。
