Antifouling paints are widely used to avoid organisms settling on boat hulls. The active ingredients in the paints have differed over the years where lead, TBT, irgarol and diuron have been deemed too harmful to non-target organisms and subsequently been banned within the EU. Most of these compounds however are persistent in the environment and can cause problems long after they are deposited. We have examined if present-day and banned substances used in antifouling paints can be found in sediments in a national park on the Swedish west coast. Sampled locations include waterways, natural harbours and small marinas for leisure crafts to investigate if number of visiting boats affect the concentration of antifouling compounds in sediments. Few significant differences were found when comparing the different locations types, suggesting that overall boat presence is more important than specific mooring sites, however, several banned antifouling compounds were found in the surface sediments.
防污漆被广泛用于防止船体上的生物附着。多年来，防污漆中的有效成分有所不同，其中铅、三丁基锡、Irgarol 和敌草隆由于对非目标生物有太大的危害而被欧盟禁止使用。然而，这些化合物中的大多数在环境中具有持久性，并且在它们被沉积后很长时间仍会造成问题。我们已经研究了目前和被禁止的防污漆中的物质是否可以在瑞典西海岸的一个国家公园的沉积物中找到。采样地点包括航道、天然港口和小型游艇码头，以调查游船数量是否会影响沉积物中防污化合物的浓度。在比较不同的地点类型时，发现几乎没有显著差异，这表明总体上船只的存在比特定的停泊点更为重要，但在表层沉积物中仍发现了几种被禁止的防污化合物。
