Analysis of cyanotoxins in Desertifilum and Leptolyngbya from Veeranam Lake: a potential health risk for Chennai, India

Abstract

Abstract Globally, dwindling potable water supplies and toxic waste triggered by human activities and climate change are substantial concerns. Below these occurrences, the suitability of drinking water regulations and their diligent execution are critical issues in maintaining human health. Unfortunately, even in developed countries, many infectious diseases (and other unidentified health effects) are linked to drinking water. These changes impact the harmful growth of Cyanobacteria or blue-green algae. Cyanobacteria-produced toxins can harm humans if they compromise drinking or ingested foods. Toxins like microcystin kill humans and creatures, leading to severe medical conditions. The present research focussed on the isolation, and identification of Cyanobacteria from the Veeranam Lake in the Cuddalore district of Tamil Nadu, India. The (ADDA)-specific ELISA technique is preferred to check the cytotoxicity in identified strains. The IC50 values of Leptolyngbya sp. showed 17.72 (g/L), and Desertifilum sp. exhibited 19.38 (g/L). Consequently, in (ADDA)-specific Microcystin quantitative assessment, Desertifilum sp. had higher toxin concentrations than Leptolyngbya sp. after the samples' singlet, duplicate, and triplicate values. Such toxicity evidence indicates that the concerns necessitate monitoring and maximum sustainability, especially when considering the various incipient toxins and the constantly evolving techniques to deal with them.
