Summary: The cause of harmful algal blooms has been a mystery, but research using genetic technologies has made progress in understanding its mechanism. A long-term monitoring of toxic algae and its associated bacteria as a community, known as 'holobiont', in Chilean coastal waters has been conducted from the perspective of bacteria as the driver of algal blooms. This review discusses the challenges of holobiont monitoring, particularly in standardization and compliance with monitoring protocols, to ensure reliable and sustainable data collection. It suggests adopting the high-throughput sequencing (HTS) standard operating procedure (SOP) by the International Human Microbiome to enhance the quality and consistency of holobiont monitoring in the harmful algal world.

Summary: An unprecedented harmful algal bloom dominated by Karenia selliformis occurred off the southeastern coast of Hokkaido, Japan, in 2021. The study found that the development, maintenance, and decay of the bloom were primarily controlled by changes in water temperature. The vertical diffusion following marine heatwaves contributed to the formation and acceleration of the bloom, but the bloom could still occur in the absence of marine heatwaves.

Summary: Planktothrix agardhii dominates the cyanobacterial harmful algal bloom community in Sandusky Bay, Lake Erie, USA, from May through September, being host to a known obligate parasite, the chytrid Rhizophydium sp. Specific infections by isolated chytrids were limited to Planktothrix planktonic species, with varying degrees of infectivity and preferences for different host isolates, suggesting possible ecological partitioning even within the same sample population. Infection mechanisms by chytrid parasites led to the release of intracellular microcystin toxins from the hosts, highlighting the importance of medium choice for experimental outcomes and the need to understand host-pathogen relationships to effectively model the ecology of cyanobacterial harmful algal blooms.

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: During harmful algal blooms (HABS), permanganate can be used as a preoxidant to improve drinking water quality by removing algal cells and degrading algal toxins. However, permanganate oxidation also alters the precursors of disinfection byproducts (DBPs) from intracellular algal organic matter (AOM), affecting DBP formation during disinfection. This study evaluated the impacts of permanganate preoxidation on DBP generation during chlorination and chloramination of AOM. The results showed that permanganate preoxidation increased the formation of certain DBPs and decreased others, indicating a complex interaction between permanganate and AOM.

Summary: Manipulating the decomposition of agricultural straws by white-rot fungi can enhance the antialgal efficiency and lead to the discovery of new allelochemicals called sphingosines. These sphingosines exhibit superior antialgal capability, with lower effective concentration compared to other known antialgal chemicals. The growth suppression of algae is triggered by programmed cell death, dysfunction of photosystem and antioxidant system, and disruption of CO2 assimilation and light absorption.

Summary: Algal blooms in inland lakes have shown divergent trends over the past 37 years, with increasing and decreasing frequencies and extents observed in different regions. North America experienced an intensification of algal blooms before 1999, followed by a decrease in severity after the 2000s. Asia had the strongest intensification of algal blooms, followed by South America, Africa, and Europe. Anthropogenic factors had slightly stronger contributions to algal bloom intensification compared to climatic drivers.

Summary: Aquatic ecosystems contribute 50% of global productivity and play a crucial role in mitigating climate change. Factors such as water temperature, ocean acidification, nutrient availability, deoxygenation, and exposure to UV radiation interact to either enhance or decrease productivity. While ocean warming and deoxygenation may have opposite effects on mitochondrial respiration, they synergistically affect plankton migration and N-2-fixation of diazotrophs. Ocean acidification and elevated pCO(2) have controversial effects on marine primary producers, but they can worsen viral attacks on microalgae and reduce calcification of algal calcifiers when combined with UV radiation. Field observations over a long period of time are limited, but future studies are expected to explore the responses and mechanisms to multiple drivers in different regions.

Summary: The marine picocyanobacterium Synechococcus plays a significant role in primary production in the global oceans. However, its responses to changing pCO(2) and light levels have been poorly studied. This research found that the growth of Synechococcus strain CB0101 is strongly influenced by light intensity, with peak growth at 250 μmol m(-2) s(-1). Elevated pCO(2) inhibits cell growth at high light intensities and decreases photosynthetic carbon fixation rates. It also significantly reduces particulate organic carbon and nitrogen, particularly under low light. These findings suggest that future ocean acidification may affect the growth and competitiveness of Synechococcus in surface waters.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
