Summary: Harmful algal blooms (HABs) are increasing globally, and the relationship between HAB aerosols and human health remains unclear. This review synthesizes current knowledge and identifies gaps in understanding this relationship. Some HAB aerosols have been linked to respiratory outcomes, but direct measurements of aerosol or toxin concentrations are lacking, and epidemiological studies are limited. Further research is needed to explore the health effects of other HAB species, dose-response relationships, effects of concurrent exposures, the impact of long-term exposures, and disparities in vulnerable populations.

Summary: This study analyzed the temporal and spatial variability of harmful algal blooms (HABs) in coastal waters of Fujian. It found that the number and impact area of HABs varied significantly over different decades, with the highest occurrence in the 2000s. The proportion of HABs caused by dinoflagellates decreased, while the proportion caused by diatoms increased. In the 2010s, toxic HAB events caused by Karenia mikimotoi increased in frequency and spatial coverage along the central Fujian coast.

Summary: This study investigates the effects of climate change on harmful algal blooms (HABs) in coastal China. The researchers analyze HAB observed data since 1981 and identify the key environmental drivers of HABs, such as nutrients, sea surface temperature (SST), and precipitation. The results show that HABs have expanded their geographic range and increased their impacting period in China's near seas. Rising total nitrogen (TN) or SST is found to be the dominant factor driving the increase in HABs. The study highlights the importance of controlling watershed nutrient input to mitigate marine eutrophication.

Summary: Harmful algal blooms pose a threat to human health, local economies, and coastal ecosystems. The use of GAMMs and climate simulations predicts an increase in blooms of Dinophysis acuminata and Dinophysis norvegica, while blooms of Pseudo-nitzschia seriata are predicted to stabilize or decrease in the future on the Canadian East Coast.

Summary: Harmful algal blooms are a global issue with significant negative impacts on aquatic environments and human health. However, the current monitoring and control methods have limitations, which restrict their practical application. Therefore, there is a need to improve existing approaches for monitoring and controlling harmful algal blooms.

Summary: This study explores the use of TROPOMI's red SIF for detecting Karenia brevis, comparing it with the standard remote sensing HAB indicator MODIS-Aqua. The results show that red SIF provides more spatiotemporal fluorescence information than nFLH and can be used for detection under cloudy conditions, which improves early warning systems for harmful algal blooms.

Summary: Climate change and anthropogenic pressures have significantly impacted coastal environments, including Zhanjiang Bay, which has experienced increased eutrophication and harmful algal blooms (HABs). Nutrient patterns have changed over the past 30 years, resulting in a shift from a phosphorus-limited oligotrophic state to a nitrogen-limited eutrophic state. Integrated land-ocean environment management is needed to mitigate pollution sources and control HABs.

Summary: Coastal harmful algal blooms (HABs) in China's seas, particularly in the East China Sea, have attracted researchers' attention for decades. The impact of climate change and anthropogenic dominant factors on HABs is not well quantified, but future projections indicate a significant increase in HAB events in the East China Sea due to climate change.

Summary: In this study, a novel TP@Fe3O4 magnetic composite was used in combination with magnetic flocculation and sulfate radical-based advanced oxidation processes (S-AOPs) to efficiently remove Microcystis aeruginosa and algal organic matters. The TP@Fe3O4 showed a high positive charge, resulting in a high algae removal rate at a modest dosage. The system of PMS/TP@Fe3O4 successfully reduced the TP@Fe3O4 dosage and effectively degraded AOMs. Through UV/PMS oxidation, a significant removal of microcystin and DOC was achieved. This method provides a non-destructive approach to mitigate harmful algal blooms.

Summary: Under the influence of climate warming and human activities, large lakes worldwide have experienced an increase in eutrophication and algal blooms. This study utilizes daily satellite observations to develop an algorithm that accurately identifies the spatiotemporal distribution of algal bloom dynamics in large lakes. The findings show positive trends in bloom area, frequency, and an earlier bloom time, with climate factors and human activities identified as key drivers.

Summary: Harmful algal blooms pose a significant challenge to the operation of seawater reverse osmosis desalination plants. This study reviews the historical changes and current status of pretreatment applications for large desalination plants and evaluates the efficiency of these systems in mitigating the impact of harmful algal blooms. The study also proposes future strategies for intelligent monitoring, improvement of unit processes, and utilization of algal biomass for greener operation.

Summary: In this study, 1064 nm confocal Raman spectroscopy combined with multivariate statistical analysis techniques was used to measure the differences in cell viability of different phytoplankton species. The combination of near-infrared Raman spectroscopy and multivariate data analysis allowed for reliable monitoring of small spectral changes and identification of specific features that classify cells as viable or nonviable. Carotenoid bands at 1527 and 1158 cm(-1) showed the most significant differences upon cell death.

Summary: This review article discusses the complex and dynamic interactions between bacteria and phytoplankton in aquatic ecosystems, with a focus on algicidal interactions. Bacteria can control algal growth through physical association or the production of algicidal compounds. The article highlights the specificity of bacterial control, mechanisms for activity, and chemical and biochemical analysis of these interactions. It also reviews the development of environmentally friendly or sustainable methods using algicidal bacteria or compounds derived from bacteria to control harmful algal blooms. The article concludes with potential avenues for future research and the further development and application of bacterial algicides.
