“…The main factors affecting the removal of algae include the water quality parameters of the test water, such as pH, turbidity, total nitrogen, and total phosphorus (Lucero et al, 2018;Hu et al, 2022), and the control parameters of the electro-flotation process, such as current density, electrode spacing, and residence time (Souza et al, 2016;Antonyováa and Antonyb, 2018). Under the current situation of general eutrophication of lakes and reservoirs, it is difficult to solve the problem of excessive endogenous nutrients in the short term, and it is impossible to Frontiers in Environmental Science frontiersin.org fundamentally eliminate the basic conditions that lead to abnormal algal reproduction, therefore insisting on the implementation of source control strategies.…”

In order to reduce the influence of algae on the conventional treatment process of the water plant, the electro-flotation process was used to test the raw water of a lake-type reservoir. After raw water with cyanobacteria as the dominant algae is treated by the best electro-flotation process, the average removal rate of algal density can reach 99.1%. The effects of current density, residence time, and electrode spacing on the algal removal efficiency of the electro-floating process were investigated by orthogonal experiments. The order of influence was current density > residence time > electrode spacing. Considering economics, the optimal process conditions were as follows: the current density was 5 mA/cm2, the dwell time was 6 min, and electrode spacing was 10 mm.

“…This adversely affects the ecosystem. Toxins from harmful algal blooms (HABs) can poison or even kill shellfish and other marine organisms and can be passed on to humans through the food chain or direct contact, thus causing poisoning and even death in humans (Klijnstra et al, 2021;Hu et al, 2022). About half of all unnatural deaths in marine mammals can be attributed to ingestion of HABs or animals contaminated with them and cause about 60,000 annual poisonings worldwide (Griffith and Gobler, 2020;Klijnstra et al, 2021).…”

Okadaic acid (OA) is a biotoxin from marine microalgae and widely present in shellfish, which severely affects the seafood safety. Therefore, it is essential to establish a highly sensitive OA analysis and detection method. In this study, a new type of immunoassay technology was established on the basis of the competition method using time-resolved fluoroimmunoassay (TRFIA). OA-bovine serum albumin (OA-BSA) coated on a 96-well plate competes with OA standard or samples to bind OA antibodies. A rare-earth ion-labeled secondary antibody, which fluoresces strongly under the effect of the enhancement solution, was then added as a tracer for detection. The established linear range of OA detected by TRFIA was 2.49 × 10-3 – 50 ng/ml, and the limit of detection was 2.49 × 10-3 ng/ml. The average coefficients of variation from intra-assay and inter-assay batches were 3.34% and 5.87%, respectively, and the recovery rate was 93.04%–111.66%. The OA in shellfish samples was determined by TRFIA and high-performance liquid chromatography (HPLC), and the results showed a good correlation. This study established a TRFIA to detect OA, which has the characteristics of simplicity, sensitivity, precision, and high accuracy, far exceeding the EU or the US standards for the detection of shellfish toxins. It is expected to make proper contribution in marine biotoxin detection.
