Abstract:

The presence of Blue-green algae (BGA) toxins in surface water sources and recreation is receiving increasing attention around the world as a public health concern. However, potential risks from exposure to these toxins in contaminated health food products that contain BGA have been largely ignored. Toxic BGA produces compound called microcystin. Fine-grained sediment is a natural and essential component of river systems and plays a major role in the hydrological, geo-morphological and ecological functioning of rivers. These complex nutrient influx increases pollution in the frequency and severity of toxic algae blooms in freshwater river has been a major concern for small communities that rely on them for drinking water supply. The present investigation observed the potency of bi-toxin (Cyanotoxin) in surface water reservoir and also the applications of the method for risk assessment and mitigation for five case studies, including Rasoolabad Ghat, Daraganj Ghat, Ram Ghat, Sangam and Chhatnag Ghat, Allahabad city. A hazard quotient approach to risk characterization is employed to analyze the effectiveness of treatment methods for removal of cyanotoxins, in addition to in-water reservoir (possibly through sediments reduction) as part of a suite of approaches, for restoration of eutrophic reservoir in general and running water for no risk of cyanotoxin.
