“…They should be interpreted in reference to WHO alert levels. Our previous study 13 assessed probe readings by using different hourly (2,6,12,18) moving averages, daily and weekly moving averages. And the study concluded that 2 hour moving average provides actionable information to the plant manager to be vigilant, indicating the need for immediate corrective action.…”

“…In recent years, there has been an increase in the occurrence of potentially toxic cyanobacterial (CB) blooms in water supply systems around the world, [1][2][3] due to climate change and human activities. 4,5 Cyanotoxins can cause a range of health problems, including skin diseases, gastroenteritis, Alzheimer's disease, and liver damage.…”

“…Cyanotoxins that are intracellular and extracellular (dissolved) can be removed using various techniques. Numerous techniques have been utilized to remove internal cyanotoxins, including coagulation/sedimentation, coagulation-dissolved air flotation (DAF), micro- and ultrafiltration, and pre-treatment oxidation [ 343 , 344 , 345 , 346 , 347 , 348 , 349 ]. While some techniques for eliminating extracellular (dissolved) cyanotoxins have been mentioned in the literature, these techniques include membranes (nano- and ultrafiltration), potassium permanganate, ozonation, the use of free chlorine, ultraviolet radiation, physical cyanotoxin adsorption using powdered activated carbon (PAC), granular activated carbon (GAC), and activated carbon adsorption [ 350 , 351 , 352 , 353 , 354 ].…”

Blue-green algae, or cyanobacteria, may be prevalent in our rivers and tap water. These minuscule bacteria can grow swiftly and form blooms in warm, nutrient-rich water. Toxins produced by cyanobacteria can pollute rivers and streams and harm the liver and nervous system in humans. This review highlights the properties of 25 toxin types produced by 12 different cyanobacteria genera. The review also covered strategies for reducing and controlling cyanobacteria issues. These include using physical or chemical treatments, cutting back on fertilizer input, algal lawn scrubbers, and antagonistic microorganisms for biocontrol. Micro-, nano- and ultrafiltration techniques could be used for the removal of internal and extracellular cyanotoxins, in addition to powdered or granular activated carbon, ozonation, sedimentation, ultraviolet radiation, potassium permanganate, free chlorine, and pre-treatment oxidation techniques. The efficiency of treatment techniques for removing intracellular and extracellular cyanotoxins is also demonstrated. These approaches aim to lessen the risks of cyanobacterial blooms and associated toxins. Effective management of cyanobacteria in water systems depends on early detection and quick action. Cyanobacteria cells and their toxins can be detected using microscopy, molecular methods, chromatography, and spectroscopy. Understanding the causes of blooms and the many ways for their detection and elimination will help the management of this crucial environmental issue.

“…In simple words, biotoxins known as phycotoxins, which are generated by harmful algal blooms species (HABs), can bioaccumulate in the tissues of mussel shellfish during the time and, when taken by people, can result in severe/fatal shellfish poisoning syndromes. Phycotoxins pose a significant hazard to various marine life, including fish, seabirds, crustaceans, and marine mammals [53]. Additionally, cyanoHAB toxins in drinking water reservoirs may pose major health dangers to the public.…”

Phycotoxins or marine toxins cause massive harm to humans, livestock, and pets. Current strategies based on ordinary methods are long time-wise and require expert operators, and are not reliable for on-site and real-time use. Therefore, it is urgent to exploit new detection methods for marine toxins with high sensitivity and specificity, low detection limits, convenience, and high efficiency. Conversely, biosensors can distinguish poisons with less response time and higher selectivity than the common strategies. Aptamer-based biosensors (aptasensors) are potent for environmental monitoring, especially for on-site and real-time determination of marine toxins and freshwater microorganisms, and with a degree of superiority over other biosensors, making them worth considering. This article reviews the designed aptasensors based on the different strategies for detecting the various phycotoxins.
