In the last decades, due to monitoring programs and strict legislation poisoning incidents occurrence provoked by ingestion of naturally contaminated marine organisms has decreased. However, climate change and anthropogenic interference contributed to the expansion and establishment of toxic alien species to more temperate ecosystems. In this work, the coasts of Madeira, São Miguel islands and the northwestern Moroccan coast were surveyed for four groups of lipophilic toxins (yessotoxins, azaspiracids, pectenotoxins, and spirolides), searching for new vectors and geographical tendencies. Twenty-four species benthic organisms were screened using UHPLC-MS/MS technique. We report 19 new vectors for these toxins, six of them with commercial interest (P. aspera, P. ordinaria, C. lampas, P. pollicipes, H. tuberculata and P. lividus). Regarding toxin uptake a south-north gradient was detected. This study contributes to the update of monitoring routines and legislation policies, comprising a wider range of vectors, to better serve consumers and ecosystems preservation.

在过去的几十年中，由于实施了监测计划和严格的立法，由于摄入自然污染的海洋生物而引起的中毒事件有所减少。但是，气候变化和人为干扰促使有毒外来物种的扩张和建立，使温带生态系统更加温和。在这项工作中，对马德拉岛，圣米格尔群岛和摩洛哥西北海岸进行了调查，以发现四组亲脂性毒素（耶索毒素，氮杂螺环酸，果胶毒素和螺状体），以寻找新的媒介和地理趋势。使用UHPLC-MS / MS技术筛选了24种底栖生物。我们报告了这些毒素的19种新载体，其中有6种具有商业意义（P. aspera，P。ordinaria，C. pod Lampasom酒店，P. pollicipes，H. tuberculata和P.苋）。关于毒素吸收，检测到南北梯度。这项研究有助于更新监测程序和立法政策，包括更广泛的媒介，以更好地为消费者和生态系统的保护服务。
