Deadly blooms reach Britain's rivers

摘要

Toxins produced by blue-green algae in dozens of Britain's rivers and reservoirs could pose a high risk to swimmers and windsurfers this summer as outbreaks of algal blooms reach record levels. The warning comes in a report published last week by the new Environment Agency, which is in charge of the nation's rivers. But the agency admits that it has no powers to force landowners to put up notices warning about toxic blooms, even at popular swimming or paddling spots.
