Contamination profiles of antifouling biocides were investigated in a deep-sea environment in Suruga Bay Japan. Significant differences in the tributyltin (TBT) and triphenyltin (TPT) concentrations in subsurface sediment between 850 and 800 m of water depth were not observed (p < 0.05). Organotin (OT) concentrations in sediment core of 0-30.5 cm from a water depth of 800 m were investigated. The butyltins (BTs) and phenyltins (PTs) concentrations were constant between 0 and 15 cm, and, subsequently, the concentration of these compounds increased. The peaks of the BTs and PTs concentrations were observed between 18 and 19 cm. The concentrations of Irgarol 1051 decreased until a core depth of 9 cm, and, the values then became near the detection limit under the 10 cm of core depth. Perfluorooctane sulfonate (PFOS) and perfluorooctanic acid (PFOA) were detected in the sediment core (0-30.5 cm) of Suruga Bay. The concentration of PFOS was high in the 0-5-cm core depth and then decreased. The concentrations of PFOA, however, were at the values near the detection limit throughout the sediment core. The BTs and PTs concentrations in surface sediment from Tosa Bay decreased with water depth. Although Irgarol 1051 was the only alternative compound detected, the value was near the detection limit. PFOS and PFOA were detected in sediment core from Tosa Bay. The concentrations of PFOS became low as the water depth became deeper. TBT, TPT, Sea Nine 211, Diuron and Irgarol 1051 were detected in sediment core (core depth: 10 cm) from the Nankai trough (water depth: 4010 m).
在日本骏海湾的深海环境中，调查了防污生物杀灭剂的污染状况。在 850 至 800 米水深的次表层沉积物中，三丁基锡（TBT）和三苯基锡（TPT）的浓度没有显著差异（p<0.05）。研究了水深 800 米处沉积物芯 0-30.5 厘米处的有机锡（OT）浓度。在 0-15 厘米处，丁基锡（BTs）和苯基锡（PTs）的浓度保持不变，随后这些化合物的浓度增加。BTs 和 PTs 浓度的峰值出现在 18-19 厘米处。在 9 厘米的岩芯深度处，Irgarol 1051 的浓度降低，在 10 厘米的岩芯深度以下，其值接近检测限。在骏海湾的沉积物岩芯（0-30.5 厘米）中检测到全氟辛烷磺酸（PFOS）和全氟辛酸（PFOA）。PFOS 在 0-5 厘米的岩芯深度处浓度较高，然后降低。然而，在整个沉积物岩芯中，PFOA 的浓度接近检测限。土佐湾表层沉积物中的 BTs 和 PTs 浓度随水深而降低。尽管 Irgarol 1051 是唯一检测到的替代化合物，但该值接近检测限。在土佐湾的沉积物岩芯中检测到 PFOS 和 PFOA。随着水深的增加，PFOS 的浓度降低。在南海槽（水深：4010 米）的沉积物岩芯（岩芯深度：10 厘米）中检测到 TBT、TPT、Sea Nine 211、Diuron 和 Irgarol 1051。
