Summary: Edible seaweeds are a valuable source of nutrients and bioactive compounds, but they can also accumulate harmful heavy metals. This review analyzes recent research on edible seaweeds, including their nutritional composition, usage in food products, heavy metal accumulation, and trends in Chile. More research is needed to identify new types of seaweeds and ensure their safety by controlling heavy metal levels. It is important to promote the benefits of seaweed consumption and support the development of a social algal culture.

Summary: Ocean acidification poses a high threat to marine microalgae, but the role of marine sediment in the adverse effects of acidification on microalgae is largely unknown. This study systematically investigated the effects of acidification on the growth of individual and co-cultured microalgae in sediment-seawater systems. The presence of sediment significantly mitigated the growth inhibition of certain microalgal species induced by acidification, while promoting the growth of others. Additionally, the introduction of sediment affected the community stability of the co-cultured microalgae under acidification. This work demonstrates the importance of sediment in understanding the impact of ocean acidification on marine ecosystems.

Summary: The direct impact of mining activities on physicochemical and biological parameters in aquatic ecosystems increases the ecotoxicological risk of exposure to contaminants and pollutants. This study used a native and adapted floating aquatic macrophyte as a model organism to assess the environmental risk and its potential application in bioremediation of heavy metals in a gold mining area. The results showed significant bioconcentration of Cr, Pb, Cu, and Zn in the roots of the macrophyte, confirming its suitability for use in rhizofiltration. H. ranunculoides also demonstrated high potential for phytoextraction of arsenic, an essential requirement for plants in bioremediation programs.

Summary: In this study, SBSG was found to have protective effects against arsenic-induced cell damage by reducing extracellular lactate dehydrogenase activity and influencing mitochondrial membrane potential, reactive oxygen species level, malondialdehyde content, and anti-oxidative enzyme activity. Additionally, SBSG promoted nitric oxide production and inhibited the activation of the JNK signaling pathway to protect against arsenic-induced damage. This study provides new insights into the detoxification effects of SBSG on heavy metals in the intestine and suggests that SBSG can be used as a natural antioxidant to combat heavy metal toxicity.

Summary: Microplastics (<5 mm) are widespread in the world and their presence in the environment raises concerns for health and safety. This review primarily focuses on the characterization techniques of microplastics and their interaction with conventional coexisting substances such as heavy metals, organic pollutants, and nutrients. It is observed that there is a significant pollution of microplastics in various areas, especially in Africa, Asia, India, South Africa, North America, and Europe. The separation methods and characterization technologies can accurately identify the shape, abundance, color, and particle size of microplastics. Additionally, the adsorption and desorption characteristics of heavy metals and organic pollutants on microplastics vary based on their properties.

Summary: Increased dietary n-6 FA leads to reduced n-3 in tissue polar lipids in Atlantic salmon, with EPA significantly reduced while DHA remains stable. Maintaining a stable n-3 content in polar lipids can be achieved by simultaneously increasing dietary n-3 content and maintaining the same n-6:n-3 FA ratio. The study suggests that a better use of dietary EPA is achieved by keeping the dietary n-6:n-3 FA ratio low.

Summary: The use of plant-based feeds in fish farming has introduced undesirable substances such as pesticides. Research indicates that commercially produced Atlantic salmon feed may contain unsafe levels of the pesticide pirimiphos-methyl (PM-m), leading to adverse effects on fish health. Fish fed with PM-m spiked feeds showed growth reduction, oxidative stress, liver damage, and disturbances in lipid metabolism. Safe limits for dietary PM-m were determined through dose-response analysis, setting the daily safe dose for fish consumption.

Summary: A study on the evolution of life cycles in brown algae revealed that diploid growth evolves when sexual reproduction is preferred over asexual reproduction. The research also found that haploid sex determination is ancestral to diploid sex determination, and isogamous species in brown algae evolved from anisogamous ancestors, contrary to the commonly reported pattern of evolution from isogamy to anisogamy.

Summary: The Darss-Zingst Bodden Chain, a shallow lagoon on the Southern Baltic coast, was thoroughly studied in terms of hydrological, biogeochemical, and floristic and faunistic aspects. A recent revisit of a sampling site revealed a total of 103 diatom taxa in sediment and macrophyte samples collected between 2015 and 2019. Compared to the 1970s, a greater variety of epipsammic diatoms, including many small species, were observed. The study highlights the importance of combining light and electron microscopy for accurate identification of small diatoms and comprehensive understanding of diatom flora in different benthic habitats.
