A long-term programme for monitoring toxic substances in the marine environment was established in Hong Kong in 2004, focusing on chemicals of potential ecological and health concern. The programme ran on 3-year cycles, with the first two years monitoring marine water, sediment, biota, and the third year monitoring pollution sources. Twenty-four priority chemicals were measured, including dioxins/furans, dioxin-like PCBs, total PCBs, PAHs, DDTs, HCHs, TBTs, phenol, nonylphenol (NP), NP ethoxylates, PBDEs and metals. Results from the first three years of monitoring indicate that toxic substances in the Hong Kong marine environment were within the range reported for the coastal waters in China and other regions, but generally lower than in the Pearl River Estuary. The levels met the standards for protecting aquatic life and human consumption. Sewage effluent, stormwater and river water were possible sources of phenolic compounds; whereas air deposition or regional pollution, rather than local discharges, may contribute to the dioxins/furans, PAHs and PCBs found in the marine environment.
2004年，香港设立了一项监测海洋环境中有毒物质的长期计划，重点关注具有潜在生态和健康影响的化学物质。该计划以三年为一个周期，前两年监测海水、沉积物、生物群，第三年监测污染源。共检测了24种优先化学物质，包括二噁英/呋喃、类二噁英多氯联苯、总多氯联苯、多环芳烃、滴滴涕、六氯环己烷、三丁基锡化合物、苯酚、壬基酚（NP）、壬基酚乙氧基化物、多溴二苯醚和金属。头三年的监测结果表明，香港海洋环境中的有毒物质在中国及其他地区沿海水域报告的范围内，但总体低于珠江口。这些水平符合保护水生生物和人类消费的标准。污水、雨水和河水可能是酚类化合物的来源；而海洋环境中发现的二噁英/呋喃、多环芳烃和多氯联苯可能是由大气沉降或区域污染造成的，而非本地排放。
