Body feather mercury and arsenic concentrations in five species of seabirds from the Falkland Islands
Several pollutants, including heavy metals, magnify along the food chain, and top predators such as seabirds can be used to monitor their trends in the marine environment. We studied mercury and arsenic contamination in body feathers in penguins, petrels and cormorants in three islands of the Falkla...
