Summary: The study investigated the H2O2 concentration and water quality parameters in a large artificial lake near a metropolitan city, finding that the H2O2 concentration in summer was over three times higher than in winter. The lake produced more H2O2 during daylight hours compared to streams, with the lowest production rates in dark conditions. Exposure to external substances, such as heavy metals and antibiotics, increased the generation of H2O2, with antibiotics having a more pronounced effect.

Summary: The Lake in Central Park and Prospect Park Lake in New York City have extremely high levels of cyanobacteria and microcystin. These lakes have elevated levels of orthophosphate relative to dissolved inorganic nitrogen during summer months. Nitrogen consistently limits cyanobacterial populations while green algae are rarely nutrient limited. Adding public drinking water rich in phosphorus and to a lesser extent nitrogen significantly enhances the growth of cyanobacteria.

Summary: Harmful algal blooms in coastal areas can impact water sources, and this study evaluates the effectiveness of H2O2 and S2O82- reagents in treating algae-laden waters. The results show that H2O2-based processes are more efficient in inhibiting cyanobacterial growth compared to S2O82-. However, S2O82- can prevent the regrowth of bacteria, while H2O2 doses alone are not sufficient.

Summary: Cyanobacterial blooms pose a danger to human and animal health due to cyanotoxins, and traditional water treatment methods struggle to remove cyanobacterial cells efficiently. Hydrogen peroxide has been shown to suppress cyanobacterial growth effectively, with photosynthetic activity proving to be the most suitable method for rapid oxidative cell stress detection in cyanobacteria. Combined methods are recommended for efficient water treatment management.

Summary: This study found that applying hydrogen peroxide (7 mg/L) could effectively reduce the population of Microcystis sp. in both laboratory and pond trials, without affecting other algal species. The treatment also promoted the growth of beneficial algae. Additionally, it was observed that the gill status of Tilapia and Giant tiger prawn remained unaffected by the H2O2 treatment, suggesting its potential as a mitigation strategy for cyanobacteria in pond aquaculture.

Summary: In response to the criticism by Huisman et al., this article demonstrates that their claims are based on incomplete evidence, misinterpretation of data, or do not actually refute our model. While our model, like any ecosystem models, has its simplifications and uncertainties, it outperforms existing approaches that ignore biology and cannot predict toxin concentration.

Summary: This study investigates the potential role of quorum sensing in mediating the interaction between Microcystis aeruginosa and heterotrophic bacteria. The luxS and mcyB genes in M. aeruginosa PCC7806 were examined, and it was found that luxS gene expression is consistent in algal bloom scenarios, while mcyB gene expression is related to cyanotoxin production rather than algal blooms.

Summary: Microcystis spp. are photosynthetic prokaryotes that can convert CO2 and minerals into organic compounds and biomass. While considered as a potential protein source for animal feeds, Microcystis also produce cyanobacterial toxins that present health hazards. Further research on nutritional value and safety is needed before incorporating Microcystis into animal feed ingredients.

Summary: The application of hydrogen peroxide (H2O2) in controlling harmful algal blooms is affected by algal density and species. While H2O2 effectively eliminated algal biomass, using high dosages could lead to increased nutrients and toxins in water. Moreover, higher concentrations of H2O2 altered the phytoplankton community diversity and may result in acute toxicity to zooplankton.

Summary: The spatial dynamics and composition of picophytoplankton in Lake Hongze were investigated using flow cytometry and high-throughput sequencing. Picocyanobacteria dominated the community, while photosynthetic picoeukaryotes were diverse but less abundant. Environmental factors, particularly total phosphorus, suspended solids, and chemical oxygen demand, showed spatial differences with higher concentrations near the river channel. The abundances of different picophytoplankton groups exhibited similar spatial patterns, being negatively related to certain environmental factors like suspended solids and chemical oxygen demand.

Summary: The study found that photosynthetic picoeukaryotes (PPEs) are the dominant group of autotrophic picophytoplankton in the highly eutrophic Lake Taihu, with higher abundance at night than during the day. Environmental variables significantly influenced PPE community composition, with the daily effect being more important than the diurnal effect over a 3-day period. Stochastic processes, rather than deterministic processes, played a key role in shaping the PPE community assembly over a short temporal scale.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
