Role of Rotifers in Betanodavirus Transmission to European Sea Bass Larvae

Frontiers in Veterinary Science, 2022
Marine invertebrates such as rotifers or Artemia, frequently used for fish larvae feeding, can be a potential source of pathogens. It has been demonstrated that Artemia can act as a nervous necrosis virus (NNV)-vector to Senegalese sole larvae. Therefore,

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Ecotoxicological Assessment of Mercury in Fish From a Gold‐Mining‐Impacted Amazonian River: Biomonitoring and Human Health Risk

Environmental Toxicology, EarlyView.
ABSTRACT The Peixoto de Azevedo River, located in northern Mato Grosso, southern Brazilian Amazon, has a long history of artisanal and small‐scale gold mining (ASGM). This study evaluated total mercury (THg) concentrations in fish tissues to assess biomagnification and potential risks.
