Quantifying the Effect of Transient and Permanent Dietary Transitions in the North on Human Exposure to Persistent Organic Pollutants and Mercury

Globally, human exposure to persistent organic pollutants (POPs) and mercury is strongly influenced by diet. Moreover, it is well known that dietary POP and mercury exposure risks vary greatly based on where foods originate from and how they are prepared. This implies that contaminant exposure can be affected by changes in diet. Such dietary changes may involve transitions from one food type or source region to another, i.e. populations gradually shifting from a local traditional food (TF) diet to one including more imported food, or they may involve transient changes during major life stages, i.e. mothers adjusting their diet during pregnancy and nursing. Additionally, such dietary changes may relate instead to changing food preparation, for example individuals continuing to eat the same types of food but altering their cooking methods. Here we propose an approach to quantify the effect of such dietary changes on human POP and mercury exposure by combining the use of computer-based simulation models and experimental TF study. At the same time we will attempt to estimate how much these changes affect the intake of beneficial nutrients. We hope that our model and analytical results may eventually be used to inform Northern food consumption choices that minimize risk from POPs and mercury while maximizing diet nutritional values.
