SETAC Europe 2020 Session: Marine and Freshwater Pelagic and Benthic Harmful Algal Blooms

SETAC Europe 30th Annual meeting will take place on 3-7 May 2020 in Dublin, Ireland.

A Session on “Marine and Freshwater Pelagic and Benthic Harmful Algal Blooms: Toxins Production, Detection, Fate, Effects, Monitoring and Management” (Co-chairs Triantafyllos Kaloudis, James Lazorchack) is scheduled under “Track 6”. 

You can submit your abstracts by 27 November 2019.

Harmful algal blooms (HABs) in freshwater and marine systems are defined as an assemblage of eukaryotic or prokaryotic plankton which have the potential to cause negative health, ecological or economic impacts. These negative impacts are caused by mechanisms that include, but are not limited to, public health and environmental risks from toxin(s) production, light attenuation, diurnal swings in pH and dissolved oxygen, offensive tastes and odors, and impaired visual aesthetics. Examples of some of the major toxins found in various combinations are: (a) prokaryotes (cyanobacteria) – microcystins, cylindrospermopsins, anatoxins, nodularin and saxitoxins; and (b) eukaryotes (dinoflagellates, diatoms, chrysophytes and raphidophytes) euglenophysins, prymensins, brevetoxins, ciguatoxins, saxitoxins and domoic acid. In recent years, there has been new information about the potential threat of benthic (attached and/or buried) toxin-producing cyanobacteria and algae. However, there are still many uncertainties about planktonic and benthic cyanobacteria/algae and the nature of their benthic/pelagic life stages. There is also some uncertainty concerning whether there is a greater risk to aquatic life due to the effects of filamentous and matt forming toxin and non-toxin producing algae on feeding inhibition and smothering. What are the current knowledge gaps related to blooms of benthic cyanobacteria/algae on substrates (attached) and/or in sediment (buried)? What research is required to address these gaps? Do we have enough knowledge to develop mitigation plans and predictive models? What tools are available to track and monitor benthic cyanobacteria/algae and their associated toxins in freshwater and marine environments, and are these fit for purpose? What information do we need to make informed risk assessments and are our current tools/techniques sufficient? How should we best incorporate ‘omics techniques into benthic cyanobacterial/algal research? What are the risks of filamentous of matt forming cyanobacteria and algae? What are the current regulations available to address both benthic and pelagic HABS and what are the current difficulties in managing the conditions that contribute to toxin production? To help address these questions, the objective of this session is to exchange information on the distribution, detection, identification, , occurrence and interaction of both benthic and planktonic cyanobacteria and algae and their associated toxins and finally management tools or approaches to reduce occurrence of blooms.

Join us in a HABs session – SETAC Annual Meeting, Rome, May 2018

 You are invited to submit abstracts for a Session titled “Global Challenge of freshwater and marine harmful algal blooms (HABs): treatment, detection, toxic effects, risk assessment and management” (Session 4.12) within SETAC Europe 28th Annual Meeting, to be held on 13-17 May 2018, in Rome.

This session on freshwater and marine HABs focuses on:

1) Innovative treatment technologies such as advanced oxidation processes, nanofiltration and nanocomposites.

2) Development of methods for detection and monitoring of HABs and their toxins, including advanced chemical analysis, toxicity assays, molecular and genetic tools, electrochemical, spectroscopic or hyperspectral imaging and microscopic morphology methods and phone/tablet Apps, and instrumental methods such as online sensors providing information about toxicity (e.g., fluorescence, behavior) or field handheld fluorimeters and remote sensing.

3) Studies on toxic effects of HABs in humans and aquatic organisms, and routes of exposure (food web, recreational activities).
4) Risk assessment and risk management of HABs, including development of decision making tools, water safety plans and management practices for prevention and control of HABs and their hazardous impacts. Keywords: harmful algal blooms (HABs), toxins, detection methods, toxicity molecules to organisms, food, water, treatment approaches, natural resource extraction, eutrophication.
The deadline for abstract submissions is 29 November 2017.
