Triclosan, an antibacterial chemical found in everyday bathroom and kitchen products, is accumulating in dolphins at concentrations known to disrupt the growth and development of other animals. Scientists have found that one-third of the bottlenose dolphins tested off South Carolina and almost one-quarter of those tested off Florida carried traces of triclosan in their blood. It is the first time the chemical has been reported in a wild marine mammal – a worrisome finding, researchers say, because it shows it is building up in the ocean’s food web.
