The Atlantic puffin and other pelagic birds are excellent bioindicators of the environment, as they occupy a high trophic level. Heavy metals and other pollutants are concentrated through the food chain, and as fish are the primary food source for Atlantic puffins, the potential is great for them to bioaccumulate heavy metals such as mercury and arsenic. Measurements can be made on eggs, feathers, or internal organs and beached bird surveys, accompanied by chemical analysis of feathers, can be effective indicators of marine pollution by lipophilic substances, as well as metals. In fact, these surveys can be used to provide evidence of the adverse effects of a particular pollutant, using fingerprinting techniques to provide evidence suitable for the prosecution of offenders.
