Abnormally high temps, heavy rains lead to unusual blue green algae conditions in N.B.
However, she and other researchers have observed the presence of benthic mats on parts of the river where they haven’t been observed in the past, something she also links to heavy rainfall.She says those walking their dogs near bodies of water should still exercise caution, as this summer’s high temperatures could jump start the growth of the algae blooms.
“They do seem to be growing now and if the water levels drop to more seasonal levels we do expect them to grow very rapidly,” she said.Roxanne MacKinnon, a biologist who works with ACAP Saint John, an environmental non-profit that monitors the condition of the Saint John River, said that dogs often fall victim to the toxins from the algae because they are attracted to the blooms.
“They`re very attracted to the smell of cyanobacteria so they are the most likely animal to come in contact with them. They actually seek them out and they will ingest the material,” she said in an interview on Tuesday. “And then if it`s producing a toxin they will be ingesting a lot of toxins because they’re ingesting the cells themselves, and then unfortunately they can potentially come into contact with the neurotoxin which will shut down their respiratory system.”
