Vertical Distribution Characteristics of Microcystin in Water during the Accumulation and Deposition of Cyanobacteria
Metal oxide composites are increasingly developed under the influence of green synthesis technology. However, the lake water environment is getting worse and worse, and the contents of nitrogen (N) and phosphorus (P) are seriously exceeding the standard. The outbreak of cyanobacteria caused by eutrophication is getting worse and worse. Microcystin (MC) is a natural toxin caused by cyanobacteria. The death accidents of aquatic animals, birds, animals and even people caused by MC occur from time to time. MC-LR is the most common and abundant microcystins in MC. MC-RR is the two microcystins (L and R represent leucine and tyrosine respectively). Therefore, MC prediction in water is very necessary. However, the existing forecasting means are single and backward, and the emergency monitoring capacity is insufficient. Based on this, this paper established a cyanobacteria information collection system, analyzed and simulated the cyanobacteria sampling, analyzed the vertical distribution characteristics of microcystin during the accumulation of cyanobacteria, and studied the changes of its characteristics, thus providing a scientific basis for the prevention and control of cyanobacteria aggregation. In order to accurately predict the change of MC in cyanobacteria bloom, a set of cyanobacteria information collection system was established using modern technology to achieve the goal of real-time and accurate monitoring of cyanobacteria. The experiment showed that the concentration of MC-LR is higher than that of MC-RR in the process of cyanobacteria aggregation, regardless of the sediment thickness. In the process of blue-green algae deposition, the concentration range of MC-LR is 1.37ng/g ∼ 6.89ng/g, and the concentration range of MC-RR is 0.32ng/g ∼ 5.38ng/g. This experiment has certain significance for predicting the change of MC concentration in water and sediment during algae accumulation and sedimentation in natural water environment, and for carrying out comprehensive water environment management.
