Bulk metal analyses of surficial sediments collected around the Norwegian Crown cruise ship grounding site in Bermuda indicated significant but localized contamination of reef sediments by copper and zinc, caused by the stripping of the tri-butyltin (TBT)-free antifouling (AF) paint (Intersmooth 460) from the underside of the hull. Highest copper and zinc values were found in heavily compacted and red-pigmented sediments inside the impact scar and were comparable to levels found close to slip ways of local boat yards where AF paints from hull stripping and cleaning processes are washed into the sea. The re-distribution of AF contaminated sediments by storms and deposition on nearby reefs constitutes a significant ecological risk that could delay recovery processes and reduce the effectiveness of remediation efforts. Whilst the ecotoxicological effects of AF paint particles interspersed with sediment is unknown, and in need of further study, it is argued that the significance of AF paint contamination of grounding sites has been overlooked.
对在百慕大挪威皇家邮轮搁浅地点周围采集的表层沉积物进行的大量金属分析表明，船体底部无三丁基锡（TBT）防污漆（Intersmooth 460）的剥离导致铜和锌对珊瑚礁沉积物造成了显著但局部的污染。在撞击疤痕内压实严重且呈红色的沉积物中发现了最高的铜和锌含量，这与当地船厂滑道附近发现的水平相当，在那里船体剥离和清洁过程中产生的防污漆被冲入海中。风暴对受防污漆污染沉积物的重新分布以及在附近珊瑚礁上的沉积构成了重大的生态风险，这可能会延迟恢复过程并降低修复工作的效果。虽然散布在沉积物中的防污漆颗粒的生态毒理学影响尚不清楚，需要进一步研究，但有人认为搁浅地点的防污漆污染的重要性被忽视了。
