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.

在全球范围内，人类活动和气候变化引发的饮用水供应减少和有毒废物令人担忧。在这些情况下，饮用水法规的适用性及其认真执行是维护人类健康的关键问题。不幸的是，即使在发达国家，许多传染病（以及其他不明的健康影响）也与饮用水有关。这些变化会影响蓝藻或蓝绿藻的有害生长。蓝藻产生的毒素如果影响人类的饮酒或摄入食物，就会对人类造成伤害。微囊藻毒素等毒素会杀死人类和生物，导致严重的医疗状况。目前的研究重点是印度泰米尔纳德邦库达洛尔地区维拉南湖中蓝藻的分离和鉴定。(ADDA) 特异性 ELISA 技术优选用于检查已鉴定菌株的细胞毒性。Leptolyngbya sp . 的 IC50 值  。显示 17.72 (g/L)，以及 Desertifilum  sp。表现出19.38(g/L)。因此，在（ADDA）特异性微囊藻毒素定量评估中，Desertifilum sp。比Leptolyngbya sp.具有更高的毒素浓度。在样品的单重、重复和三次重复值之后。这些毒性证据表明，这些担忧需要监测和最大程度的可持续性，特别是在考虑各种初期毒素和不断发展的处理技术时。
