“…Moreover, Facey et al [255] explored the role of Mo on the growth and toxin production of freshwater M. aeruginosa; however, the reported results show no notable influence on growth and microcystin production. Meanwhile, studies on V in aquatic environments are mostly focused on redox geochemistry and mobility, providing limited evidence on the linkage between V and HABs [346]. A better understanding of redox metabolism in dinoflagellates, as well as physiological functions of Mo and V in both marine and freshwater HABs, could better inform on the roles of these metals in mitigating the impacts of HABs.…”

In a constantly changing environment brought about by the climate crisis and escalated anthropogenic perturbations driven by the growing population, harmful algal bloom dynamics and their impacts are expected to shift, necessitating adaptive management strategies and comprehensive research efforts. Similar to primary productivity, HABs have been thought to be driven primarily by major nutrients such as N, P, and Si. However, recent investigations on the role and importance of micronutrients as limiting factors in aquatic environments have been highlighted. This paper provides a review of metal and phytoplankton interactions, with a specific emphasis on pertinent information on the influence of trace nutrients on growth, toxin production, and other underlying mechanisms related to the dynamics of HABs. Low to near-depleted levels of essential nutrients, including Fe, Cu, Zn, Se, Mn, Co, and Mo, negatively impact cell growth and proliferation of various marine and freshwater HAB species. However, evidence shows that at elevated levels, these trace elements, along with other non-essential ones, could still cause toxic effects to certain HAB species manifested by decreased photosynthetic activities, oxidative stress, ultrastructure damage, and cyst formation. Interestingly, while elevated levels of these metals mostly result in increased toxin production, Co (i.e., yessotoxins, gymnodimine, and palytoxins) and Mn (i.e., isodomoic acid, okadaic and diol esters) enrichments revealed otherwise. In addition to toxin production, releasing dissolved organic matter (DOM), including dissolved organic carbon (DOC) and humic substances, was observed as an adaptation strategy, since these organic compounds have been proven to chelate metals in the water column, thereby reducing metal-induced toxicity. Whilst current research centers on free metal toxicity of specific essential elements such as Cu and Zn, a comprehensive account of how trace metals contribute to the growth, toxin production, and other metabolic processes under conditions reflective of in situ scenarios of HAB-prone areas would yield new perspectives on the roles of trace metals in HABs. With the growing demands of the global population for food security and sustainability, substantial pressure is exerted on the agriculture and aquaculture sector, highlighting the need for effective communication of information regarding the interactions of macro- and micronutrients with HABs to improve existing policies and practices.

“…Mercury is a common pollutant and is most toxic in its organic form. In phytoplankton, Hg will bind to cytosolic ligands and distribute into the organelles [335] wherein it may affect photosynthesis [336][337][338] and increase reactive oxygen species inside the cell [339,340]. As a consequence of toxicity, phytoplankton has devised mechanisms to counter this toxicity, which includes the conversion of ionic mercury to elemental mercury [341].…”

“…For example, the remobilization of V with soluble V concentration at 3.87 μg/L is observed in eutrophic Lake Taihu, China, due to the combined effect of the dissolved organic matter complexation and the Fe(hydr)oxides reduction. 104 Vanadium migration also occurs within ecosystems. In soils, V tends to accumulate in the rhizosphere of plants, which affects its distribution.…”

“…Occasionally, oxic sediments tend to release V to water, causing the exchange and flux of V between water and sediment. For example, the remobilization of V with soluble V concentration at 3.87 μg/L is observed in eutrophic Lake Taihu, China, due to the combined effect of the dissolved organic matter complexation and the Fe(hydr)oxides reduction …”
