What is the term for dense growth of cyanobacteria commonly misnamed 'blue-green algae'?

• A. HABs
• B. Algal blooms
• C. Cyanotoxin events
• D. Eutrophication

Answer: (A)

Dense growth of cyanobacteria in water is best described as a harmful algal bloom, or HABs. This term emphasizes not just the bloom itself but its potential danger, since cyanobacteria can produce toxins that threaten drinking water, wildlife, and recreation. While people often say “blue-green algae,” cyanobacteria are bacteria, not true algae. The broader term algal blooms doesn’t necessarily imply danger or toxin production. Cyanotoxin events focus on the toxins, not the bloom itself, and eutrophication describes the nutrient-driven process that can fuel blooms but is not the bloom.
