Hazards

Blue-green algae (cyanobacteria)

Reported by the Sudbury Star on August 26th 2010, blue-green algae has been found in Lake Nipissing. Visible algal blooms may produce toxins, the highest concentrations being located in blooms and scum; therefore, using or drinking the water should be avoided. Toxins can irritate the skin and, if ingested, can cause diarrhea and vomiting. At high enough levels, toxins may cause liver and nervous system damage.

A warning was issued by the Sudbury and District Health Unit :

If blooms are visible:


 * Avoid using the water for drinking, bathing, or showering, and do not allow children, pets, or livestock to drink or swim in the water.


 * Lakeshore residents with shallow drinking water intake pipes that might pump in bluegreen algae should be cautious.


 * Residents should not boil the water because that may release more toxins.


 * Residents should avoid cooking with the water because food may absorb toxins.
