Special Issue Information

Dear Colleagues,

Chemicals have been widely used in agricultural crops, forests, and wetlands in the last 30 years. However, the extensive use and discharge of these chemicals in aquatic environments will induce aquatic toxicology and may impair biological communities. Due to the lack of target specificity, these chemicals can cause severe and persistent toxic effects on non-target aquatic species, including invertebrates and vertebrates.

This Special Issue will cover new monitoring technologies, mathematical analysis methods, and aquatic environmental assessments of such aquatic toxicology. Increased knowledge and understanding of these issues have led to the development of new monitoring, analysis, and assessment technologies based on biological and chemical methods. We invite investigators to contribute original research articles, as well as review articles, that will stimulate the continuing development of the research areas described above.

Potential topics include, but are not limited to, the following:

  • Type analyses of environmental chemicals in the aquatic environment;
  • The transport and transformation of chemicals in aquatic environments;
  • Scientific methods for monitoring and assessing aquatic toxicology: scaling methods, the use of biological indicators/biomarkers, dynamic and commitment models, pollution indices, etc.;
  • The biological and chemical characteristics of the water pollution caused by different chemicals;
  • The design and development of sampling techniques, analysis methods, and monitoring systems of chemicals in groundwater and surface water;
  • Methods and procedures for pollution risk assessment in aquatic environments;
  • The mechanisms of cytotoxicity, genotoxicity, and tumorigenicity exerted by environmental chemicals in the aquatic environment;
  • The use of wastewater and other qualities of water;
  • Mitigation strategies for nanoparticles in water pollution;
  • The impacts of monitoring and assessment methods as a result of new trends in aquatic toxicology;
  • New laboratory techniques of emerging pollutant quantification;
  • Recent developments in water, sediment, and tissue quality guidelines;
  • The marine environment and toxicology.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The Application of an Infrared-Based ECG Acquisitor in an Online Healthy Assessment System: The Effect of Temperature on Cardiac Function in Carp (Cyprinus carpio)

Carp (Cyprinus carpio) is one of the major farmed fish species in China. In recent years, the increasing water temperature caused by global warming has caused physiological stress in fish, which in turn affects the heart function and health of the fish. Therefore, we hypothesized that the electrocardiogram (ECG) parameters of carp could reflect the temperature-induced stress. To test this hypothesis, in this study, the real-time online cardiac function assessment system (OCFAS) was used to monitor the electrocardiogram signals (heart rate, P wave, R wave, T wave, P-R interval, QRS complex, Q-T interval) of carp at different temperatures. The results showed that the heart rate of the fish increased with the temperature within a certain range. However, when the temperature exceeded this range, the cardiac function of the fish was significantly impaired. The P-R interval was shortened with the increase in the body temperature, and there was a negative correlation between them. This study emphasizes the importance of using real-time online fish ECG assessments to evaluate cardiac health, and it further improves the evaluation index system for ECG in fish. At the same time, the temperature in aquaculture and water environments requires special attention to avoid its adverse effects on the health of aquatic populations. Full article
