 In Monaco, scientists at the IAEA's Environment Laboratories are conducting research to better protect our coasts and oceans and to ensure the safety of seafood. As our oceans change, their work is becoming vital. Since the industrial era, we can see that the contamination of the coast and the ocean is increasing. Seafood is an essential source of food and revenue for millions of people worldwide. And now it's under increasing threat. In seafood safety, we're interested in looking at contaminant flows through the food web, through trophic structure. Nuclear techniques play an important role in better understanding how contaminants move through the food chain. We use radioisotopes as proxies for metals and trace elements. And we can see how these trace elements move from land to the ocean through marine organisms. One of the techniques we have developed here is basically to try to understand how the contaminants are going from the seafood to the human. And the technique is developed using radio tracer and to mimic each step of the human digestion. These laboratories have developed a way to replicate the human digestive process. This allows scientists to observe which contaminants are broken down during digestion and which remain in our system. The information gathered through this research is provided to the IAEA's member states. With this scientific data, informed decisions can be made to improve the safety of seafood. This is Alexandra Anapanich reporting for the IAEA.
