Scientific Sessions

We would like to highlight that we also welcome any contribution that does not focus marine environments!

Effects of pollutants in a multiple stressor context

Co-chairs: Ketil Hylland, Heli Routti

Chemical pollution is only one of many environmental factors that may influence the health and fitness of marine organisms. Other stressors related to human activities include marine litter and microplastics, harvesting, habitat modification, noise pollution and eutrophication. Global climate change may increase the amplitude of “natural” stress to marine organisms in terms of changes in temperature, pH, turbidity, food availability and quality, and predation. This session invites studies using observational, experimental and/or modelling approaches and contribute to our understanding of how individual stressors add up to or detract from the total stress level experienced by organisms, populations or communities. In addition, papers that quantify specific effects of individual stressors are also welcome.

Impacts and analysis of mixture toxicities

Co-chairs: Bjørn Henrik Hansen, Daniela Pampanin

Complex mixtures of contaminants from different origins (e.g., industry, agriculture, urban) display different toxicities alone or in combination. Substances may be mixtures themselves (e.g., crude oil) or chemicals emitted jointly to environmental media. When present in a mixture, they can cause complex and substantial changes in the apparent properties of individual constituents affecting bioavailability, adsorption, distribution, excretion, metabolism and interactions with targets. While environmental concentrations of most compounds are far below their individual effect thresholds, they may contribute to substantial effects when in combination. Papers studying mixture toxicities, including empirical (field based or experimental studies of whole mixtures and fraction-based) or computational (e.g., CA and IA models) approaches are invited. 

Impact of climate change on contaminant transport, fate and food web accumulation

Co-chairs: Amanda Poste, Sophie Bourgeon

Climate change is leading to increased temperatures; changing wind and precipitation patterns; loss of sea ice, glaciers and permafrost; and shifts in species distributions, ecosystem productivity, growth rates and food web structure; all of which in turn will have a broad range of direct and indirect impacts on contaminant cycling in the environment. Understanding these complex linkages is critical for predicting how climate change is likely to affect contaminant concentrations in the environment and in food webs, as well as potential implications for ecosystem and human health. In this session we aim to bring together a diverse group of researchers studying current and potential future climate change impacts on the transport, fate and food web accumulation of contaminants. We welcome observational, experimental and modelling studies focusing on effects of climate change on: 1) (re-)mobilization and transport of contaminants in the environment, 2) contaminant transformation and fate, 3) bioavailability and uptake at the base of the food web, and 4) food web structure, bioenergetics, and trophic transfer of contaminants.

Mechanistically-informed hazard and risk assessment for a sound and sustainable management of the aquatic environment

Co-chairs: Knut Erik Tollefsen, Odd Andre Karlsen

The aquatic environment has evolved as a result of human activities over the past several decades. Today, the aquatic environment contains a complex mixture of different natural and man-made chemicals and non-chemical stressors. Consequently, aquatic organisms are exposed to a wide range of stressors that have the potential to cause adverse effects on individuals, populations, species, and communities through changes in traits such as growth, reproduction, and survival. Billions of people worldwide depend on services from freshwater, marine and coastal biodiversity for their livelihoods, and maintaining healthy and productive ecosystems is therefore essential for achieving a sustainable development. Environmental monitoring programmes are commonly applied to monitor chemical and non-chemical stressors. However, these programs have proven insufficient as the direct causal relationship between the stressor and adverse outcomes are seldomly characterized due to limitations in analytical approaches, focus on limited number of stressors, and lack of toxicity information for single stressors and how they interact to cause combined toxicity. This supports the need for applying and developing alternative approaches that can be integrated into future monitoring programmes and environmental risk assessment for ensuring sustainable management of the aquatic environment. This session welcomes presentations on toxicological approaches concerning integrated chemical and biological effects monitoring, hazard and risk characterization, AOP-development, omics and mechanism-based toxicology, modelling approaches and more.

Impacts of contaminants over lifetime and generations

Co-chairs: Pål Olsvik, Jasmine Nahrgang

Many classes of contaminants including heavy metals, legacy persistent organic pollutants and contaminants of emerging concern have the capacity to lead to long-term impacts on species and possibly also to multi- and transgenerational impacts through a range of toxicity pathways. Environmental contaminants can further affect genetic diversity and contribute to population level effects. We invite presentations on recent research related to the long-term impact of contaminants to organisms and populations, over a lifetime and/or multiple generations. We welcome studies investigating effects at different levels of biological organization from mechanistic studies including epigenetic inheritance, to studies focusing on physiological and individual level impacts on fitness traits and population level studies using for instance modelling approaches or empirical data.

Fate and effects of particles on organisms

Co-chairs: Dorte Herzke and Martin Wagner

For this session, we invite presentations on recent research related to the sources, fate and impacts of natural, anthropogenic or synthetic particles, including suspended solids, mine tailings, engineered nanomaterials and nano- and microplastics. Contributions regarding three lines of research on particle impacts are invited:

  • research on the environmental levels, new analytical approaches and modelling of particle fate and dispersion from the area of environmental chemistry, including associated chemicals,
  • research into the effects of these particles and associated chemicals on biota, especially when this work focusses on improving our understanding of mechanisms and ecological consequences, and
  • Broader contributions on the ecological and societal impacts and responses to particle pollution focusing on promoting solutions.

Realizing that most of the recent research is done on plastic particles, we also invite contributions on other particulate matter to foster an exchange of knowledge and learnings from multiple fields.
