Measurements of chlordecone, an organochlorine insecticide with high persistence in natural environments, have been carried out on several species and genus of macroalgae in Guadeloupe and Martinique. These data were statistically compared to determine the ability of the genus Dictyota to accumulate chlordecone, compared to other collected macroalgae. The comparisons were conducted between phylogenetic groups (Rhodophyta, Phaeophyta and Chlorophyta), and between sites (Guadeloupe vs Martinique). Concentrations of chlordecone measured in Dictyota spp. samples were significantly higher than the other groups regardless to the site. Phaeophytes are generally characterized by a higher capacity for biosorption of contaminants. In this study, however, only the Dictyota spp. samples followed this pattern. Therefore, this genus is of interest in cases of phycoremediation of the chlordecone.

在瓜德罗普岛和马提尼克岛的大型藻类和属中，对十氯酮（一种在自然环境中具有较高持久性的有机氯杀虫剂）进行了测量。与其他收集的大型藻类相比，对这些数据进行统计比较，以确定Dictyota属积累十氯酮的能力。比较是在系统发育组（红藻，生藻和绿藻）之间以及地点（瓜德罗普岛与马提尼克岛）之间进行的。敌百虫的十氯酮浓度。无论地点如何，样本均显着高于其他组。赘生植物的特征通常是具有更高的生物吸附污染物的能力。但是，在这项研究中，只有梭菌属 样本遵循此模式。因此，该属在十氯酮的phycore介导的情况下是令人感兴趣的。
