新加坡海峡和周围海域的物理海洋学主要受潮汐和季节性净环流的控制。来自马六甲海峡、南海以及连接马六甲海峡和新加坡海峡与爪哇海的海峡的潮流相互作用使得新加坡海峡的总体流动相当复杂。作为这些相互作用的水体交汇处的一个节点，该区域内的任何排放，如漏油，都会影响周围的海洋，尽管浓度会通过混合和迁移而稀释。除了物理过程外，污染事件的最终命运还取决于水体的生物和化学相互作用，包括食物链相互作用和生物降解。对于海洋环境中持久性较强的有机物，基线研究表明，在新加坡沿海沃茨测得的多环芳烃浓度普遍高于其他地方报告的水平，而有机氯农药和多氯联苯普遍低于其他亚洲国家报告的水平，但高于世界其他地方报告的某些水平。总体而言，持久性有机污染物在新加坡沿海沃茨中的普遍存在表明，需要继续监测和评估其在海洋环境中的迁移和生物影响。
The physical oceanography of the Singapore Strait and ambient seas is governed mainly by the tides together with a seasonal net circulation. The interaction of tidal streams from the Malacca Strait, South China Sea and straits linking the Malacca and Singapore Straits to the Java Sea makes the overall flow in the Singapore Strait rather complex. Being a node at the confluence of these interacting water bodies, any discharges in the domain, such as oil spills, would affect the surrounding seas, although the concentration would be diluted through mixing and transport. In addition to physical processes, the ultimate fate of a pollution event would depend on the coupled interactions with biology and chemistry of the water body, including food-chain interactions and biodegradation. For the more persistent organics in the marine environment, baseline studies showed that concentrations of PAHs measured in Singapore’s coastal waters were generally higher than levels reported elsewhere, whereas OCPs and PCBS were generally lower than reported levels for other Asian countries, but higher than some levels reported elsewhere in the world. Overall, the prevalence of POPs in Singapore’s coastal waters suggest the need for continued monitoring and evaluation of their transport and biological impact in the marine environment.
