Harmful blue-green algal blooms and the toxic microcystins that accompany them have been a persistent threat in the lake's western basin but, until this study, bloom-related toxins had not been formally documented and analyzed in the central basin.
Submitted as an entry in the Environmental Science and Engineering Category, the winning project presents practical and affordable solution for the early detection of algal blooms (red tide) through a device that uses a set of sensors for pH level, temperature, and light intensity to measure and predict HABs.
"As well as having a negative effect on the appearance, quality and use of the water, algal blooms can also move around - you could see it one day, but it may have moved the next." Dogs who ingest the algae could suffer from vomiting, diarrhoea, drooling, disorientation, trouble breathing, seizures and blood in faeces.
Susan Fitzpatrick, natural resource management team leader for NRW, said: "We receive many inquiries about the quality of Wales' waters and while most are about genuine pollution incidents, sometimes they relate to algal blooms.
Dogs can become ill by ingesting blue green algae from water We know that some dogs enjoy nothing better than a paddle in a cool lake while on a walk in this hot weather, but my advice to pet owners would be to keep your dog on a lead during walks near water confirmed to have toxic algal blooms.
