作为审查英国 (UK) 管理疏浚海洋沉积物处置污染物行动水平 (AL) 的一部分，对三丁基锡 (TBT) 进行了重新评估。 TBT 是一种禁用的杀菌剂，能够对海洋环境造成严重危害。在对疏浚沉积物进行海洋处置之前，通常会对其存在进行筛查。使用 2000 年至 2018 年期间获得的英国监测数据对疏浚沉积物 TBT 浓度进行了研究。这些 TBT 浓度的变化指导了 AL 的重新评估。最近的毒性研究也指导了 TBT AL 的重新评估。这项研究本身是环境、食品和农村事务部更大规模审查的一部分，得出的结论是，当前的英国 TBT AL 可能不再适合其目的。建议采用更加环保的方法来控制 TBT 向海洋环境的释放。
As part of reviewing the United Kingdom (UK) action levels (ALs) of contaminants for managing the disposal of dredged marine sediment material, tributyl tin (TBT) has been reassessed. TBT is a banned biocide capable of causing severe harm to the marine environment. Its presence is routinely screened for prior to marine disposal of dredged sediment material. Dredged sediment TBT concentrations have been studied using UK monitoring data obtained between 2000 and 2018. The changes in these TBT concentrations have guided the reassessment of ALs. Recent toxicity studies have also guided the reassessment of TBT ALs. This study, which itself forms part of a larger review by the Department for Environment, Food and Rural Affairs, has concluded that current UK TBT ALs may no longer be fit for purpose. A more environmentally protective approach for controlling release of TBT into the marine environment is recommended.
