Urgent warning issued over popular US lake during July 4 celebrations
A toxic algae bloom, containing harmful cyanotoxins, has been detected in Lake Powell's Antelope Canyon, disrupting Fourth of July weekend recreation.
The detected cyanotoxin levels are at the high end of safe exposure, posing risks such as liver and kidney failure, inflammation, and potentially death for humans and animals.
Although Lake Powell remains open for recreation, park officials advise visitors to avoid swimming in affected water and not to boat on scummy areas to prevent inhaling airborne toxins.
These harmful algal blooms are becoming more frequent and prolonged due to climate change, hotter temperatures, and nutrient run-off into water bodies.
Exposure to cyanotoxins can occur through accidental ingestion or inhalation during recreational activities, with microcystin being a potent liver toxin and possible human carcinogen.
