From an environmental perspective, there is a need to reduce the amount of biocides in chemically-active antifouling (AF) coatings, as these biocides can cause severe damage to marine life. In this study, six active molecules known as booster biocides were added at 3 wt% in solvent and aqueous-based acrylic paints. DCOIT, dichlofluanid, zinc pyrithione, copper pyrithione, tralopyril and zineb were used alone and mixed with a lower amount of copper (I) oxide and copper thiocyanate (10 wt%) than is currently used or with zinc oxide fillers. Field immersion tests were carried out in the Atlantic Ocean (Ste Anne du Portzic) and the Mediterranean Sea (Toulon), with contrasting physicochemical properties of water and macrofoulers' biodiversity. Microscopic analyses showed that AF coatings reduced the bacterial density differently for short immersion times at Ste Anne du Portzic. After four/five months of immersion, results, including multidimensional analyses, showed first specific patterns in the macrofoulers' assemblages depending on the site. In addition, the structure of macrofoulers' assemblages was affected by the biocide itself and by the combination of the biocide and the binder. When efficient, AF coatings appeared to decrease the richness with a strongest effect at Toulon. DCOIT was the most performing booster biocides whatever the immersion site and the polymer binder used. DCOIT was found to be efficient against marine bacteria and macrofoulers at Ste Anne du Portzic. The combination of zinc pyrithione with ZnO fillers in an aqueous-based AF paints exhibited the highest activity in the Mediterranean Sea over 16 months of immersion.

从环境角度来看，需要减少化学活性防污 (AF) 涂料中杀菌剂的用量，因为这些杀菌剂会对海洋生物造成严重损害。在这项研究中，在溶剂型和水性丙烯酸涂料中添加了 3 重量％的六种活性分子，称为增效杀菌剂。DCOIT、双氯氟氰胺、吡啶硫酮锌、吡啶硫酮铜、tralopyril 和 zineb 单独使用，并与比目前使用的或与氧化锌填料相比更低量的氧化铜 (I) 和硫氰酸铜 (10 wt%) 混合。在大西洋 (Ste Anne du Portzic) 和地中海 (Toulon) 进行了现场浸泡测试，水的物理化学特性和大污秽物的生物多样性形成鲜明对比。显微分析表明，在 Ste Anne du Portzic 的短时间内，AF 涂层以不同的方式降低了细菌密度。经过四五个月的浸泡，结果，包括多维分析，首先显示了大污秽物组合的特定模式，具体取决于地点。此外，大型污损物组合的结构受杀生物剂本身以及杀生物剂和粘合剂的组合的影响。当有效时，AF 涂层似乎降低了丰富度，在土伦效果最强。无论使用何种浸渍部位和聚合物粘合剂，DCOIT 都是性能最好的助推杀菌剂。在 Ste Anne du Portzic 发现 DCOIT 对海洋细菌和大型污损物有效。
