Abstract(s)
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 an thropogenic 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.
