Table 2 Overview of research questions

From: Understanding microplastic pollution in the Nordic marine environment – knowledge gaps and suggested approaches

Section name

Research question

Sources, sinks and transport

How do oceanographic dynamics determine transport and fate of MPs in the Icelandic waters?

What sampling designs will best capture spatial and temporal MP distribution patterns in Nordic marine systems?

Is it possible to determine the relative contribution of MPs from long distance and local sources in the Arctic?

Is the movement of microplastics in the sea a new type of long-range transport of chemicals, including transport to the Arctic?

Exposure and potential impacts

How do MP particles move through the Nordic marine food webs?

What are the chemical and immunotoxicological biomarkers of MP exposure in the economically important Baltic herring?

What are the biological effects of MPs in the Nordic environment?
