Description

Cyanobacteria (also referred to as blue-green algae) are common photosynthetic bacteria that live in surface waters. Under favorable conditions, such as warm water and high nutrient content, these bacteria can form nuisance “blooms”. The presence of blooms in recreational water causes unpleasant aesthetics and exposure to some toxin-producing blooms may pose potential health risks. Contact with blooms can cause skin rashes and irritation, itchy eyes, and ear infections. Inhaling water may cause allergic-like reactions, runny noses or sore throats. Ingestion of toxins can cause a range of symptoms (e.g., hepatotoxic or neurotoxic effects, and even death). There has been increased public awareness as a result of research over the past 20 years, recent monitoring efforts, and increased public education on the topic. In 2009, Alberta Health and Alberta Health Services began seasonal monitoring for cyanobacterial blooms at high use recreational beaches. In 2019, beach operators took over...

Description

Harmful blue-green algae (toxic cyanobacteria) blooms in surface water are prevalent in Alberta. The presence of blue-green algae in recreational water causes unpleasant aesthetics, and exposure to some toxin-producing blue-green algae may pose potential health risks. There have been increased public awareness and health concerns as a result of increased research and public education over the past 20 years. This report presents the results of programs for monitoring cyanobacteria on Alberta beaches conducted by Alberta Health and Alberta Health Services between 2010 and 2013. It discusses the objectives and presents the findings of the monitoring programs and lists recommendations for further monitoring studies.
