The Goal Is to Investigate the Effects of Common Pesticides on the Growth and Biochemical
Parameters of some Cyanobacteria Species, Isolate, Purify, and Identify Cyanobacterial Strains, Growth
Kinetics of Purified Samples, and Biochemical Parameters Under Selected Metal Stress, As Well As The
Frequency of Heterocyst and Akinete Under Control and Treated Conditions. the Subarnarekha River
Basin, Which Runs Through Ranchi District In India's Jharkhand State, Served As the Study Area. Paswspss-
18 Was Used to Calculate One Way Anova and Multiple Co-Relations to Investigate the Probability
Distribution Pattern and Significance of the Collected Data. Higher Amounts of Mda Accumulation Under
Treatment Conditions Might Be the Consequence of Photosynthetic Membrane Rupture, Which Causes A
Brief Rise In Sod Activity In the Test Organism. Mda an Increase In Sod Activity Might Be Used As A
Biomarker For Metal Exposure. When Nostoc Carneum Blooms In Water, It Provides More Surface Area For
The Metal Binding Abilities of the Other Two Species, Potentially Making It a Highly Effective Heavy Metal
Removal Agent. Furthermore, It Is Cost-Effective, Ecologically Friendly, and Can Be Mass-Produced.
