New Invertebrate Vectors for PST, Spirolides and Okadaic Acid in the North Atlantic
Abstract: The prevalence of poisoning events due to harmful algal blooms (HABs) has declined during the last two decades through monitoring programs and legislation, implemented mainly for bivalves. However, new toxin vectors and emergent toxins pose a challenge to public health. Several locations o...
