In Arctic populations, a primary route of exposure to contaminants is through the diet. The health risks associated with these exposures can be characterised by conducting human health risk assessments. However, while there is guidance from many international and national organisations, there are limited examples of human health risk assessment in the Arctic. The 2022 AMAP Human Health Assessment Report was the first AMAP report to describe, in one place, the utility of food-based, dietary intake-based and human tissue-based contaminant data in estimating risk. Here, we present available tools, case studies and challenges associated with conducting human health risk assessments in the Arctic. Future efforts in the Arctic should be able to use this information to best interpret human exposure to contaminants in a risk-based context.

Over the last three decades, the Arctic Monitoring and Assessment Programme has published five human health assessments. These assessments have summarised the current state of the science regarding environmental contaminants and human health in the Arctic. The 2021 Human Health Assessment Report had a particular focus on dietary transitions, in addition to human biomonitoring levels and trends, health effects, risk assessment methodologies, risk communication and multi-disciplinary approaches to contaminants research. The recommendations and research priorities identified in the latest assessment are summarised here to assist decision- and policy-makers in understanding and addressing the impacts of contaminants on human populations in the Arctic.
