BOSTON – The flounders of Boston Harbor, formerly notoriously polluted, are now free of tumor.
Scientists at the Woods Hole Oceanographic Institution say, in a new study, that decades of cleanup efforts have led to a reversal in the health of the winter flounder.
Researchers say the port of Boston was so polluted in the late 1980s that more than three-quarters of the species showed signs of liver disease.
But Woods Hole biologist Michael Moore, author of the study, says his team has not found a cancerous tumor on a flounder since 2004. He has been monitoring the species since 1986.
Moore credits the completion of a new sewage treatment plant and dump tunnel nearly 15 km long in recent decades.
The Woods Hole study was published in the academic journal Diseases of Aquatic Organisms.
