**4. Hazards resulting from algal toxins**

Environmental parameters such as temperature, illumination, pH, salinity, macroand micronutrients are among the most important regulators of toxins production from blue-green algae, according to environmental studies in continuous cultures of algae. Microcytins and Anatoxin-a are maintained to a significant extent inside the cell. Because the degree of (Microcytins) harm to the environment and neighboring creatures increases as the logarithmic length of growth increases, the presence of (Microcytins) cannot be overlooked. According to certain research, the quantities of

toxins in water containing creatures that emit toxins range from (1–100 g/l) and can be higher, and as a result, (microcytins) are among the contents that pose a health risk and have an effect if the water has been ingested from change the detoxification of cyanobacteria and their cells [15].
