Mitigation of nitrite toxicity by increased salinity is associated with multiple physiological responses: A case study using an economically important model species, the juvenile obscure puffer (Takifugu obscurus)

Adsorption Capability of Fe-HT3.0 for Nitrite and Nitrate Ions in a Binary Solution System

“…This result attributes to the higher charge density of nitrate ion compared to that of nitrite ion. 1,8) Effect of Contact Time on the Adsorption of Nitrite and Nitrate Ions Figure 2 shows the effect of contact time on the adsorption of nitrite and nitrate ions. The amounts of nitrite and nitrate ions rapidly increased during the first 2 h. Equilibrium was attained within 6-24 h under the experimental conditions.…”

“…Nitrites and nitrates (nutrients) have caused widespread concern for surface and groundwater safety around the world due to their impacts on human health (cyanosis in children and cancers of the alimentary canal) and ecological systems (eutrophication). 1,2) Agricultural overapplication of natural and synthetic fertilizers, aquaculture, municipal wastewaters, detergent manufacturing, and mineral processing industries are the main sources of nutrient release into the aquatic environment. 3,4) The WHO guideline for nitrite (NO 2 − -N) in drinking water is 0.91 mg/L.…”

Toxicidade de compostos nitrogenados em peixes influenciada por parâmetros físico-químicos da água: uma revisão narrativa

“…A salinidade é outro fator ambiental fundamental, pois pode afetar o desenvolvimento e as taxas de sobrevivência dos peixes (Yang & Chen, 2006). Peixes migratórios foram expostos ao nitrato elevado e diferentes níveis de salinidade, e os resultados mostram que níveis de salinidade mais altos foram capazes de mitigar os efeitos do nitrito em testes de toxicidade aguda (Kir & Sunar, 2018;Wang et al, 2017). Com o aumento da salinidade nos níveis testados (10, 20 e 30 ppt) o peixe dourada do mar foi mais tolerante ao nitrito, diminuindo os efeitos tóxicos (Kir & Sunar, 2018).…”

“…Com o aumento da salinidade nos níveis testados (10, 20 e 30 ppt) o peixe dourada do mar foi mais tolerante ao nitrito, diminuindo os efeitos tóxicos (Kir & Sunar, 2018). Resultado semelhante foi encontrado em baiacu obscuro (Takifugu obscurus), em que o nitrito foi capaz de diminuir significativamente as taxas de sobrevivência dos peixes juvenis, e o aumento da salinidade mitigou esses efeitos, aumentando as taxas de sobrevivência (Wang et al, 2017).…”

Integrative Biomarker Assessment of the Influence of Saxitoxin on Marine Bivalves: A Comparative Study of the Two Bivalve Species Oysters, Crassostrea gigas, and Scallops, Chlamys farreri

“…Due to the variation in the mechanisms involved in the organisms when they are exposed to the pollutant, results interpretation from a combination of the biomarkers has more advantage than interpreting single biomarker results. As results interpretation from multi-biomarker could provide the overall impact of a specific pollutant (i.e., STX), the integrated biomarker responses (IBRs), as an indicator of environment stress, has been widely used in stress responses and ecological risk assessment of marine pollutants including toxins ( Beliaeff and Burgeot, 2002 ; Wang et al, 2011 , 2018 ; Pain-Devin et al, 2014 ; Yan et al, 2014 ; Martínez-Ruiz and Martínez-Jerónimo, 2015 , 2017 ; Nogueira et al, 2015 ; Meng et al, 2016 ; Teles et al, 2016 ; Vieira et al, 2016 ; Devin et al, 2017 ; Duarte et al, 2017 ; Li et al, 2017 ; Luna-Acosta et al, 2017 ; Sanchez-García et al, 2017 ; Sobjak et al, 2017 ; Valerio-García et al, 2017 ). In addition, the integrated approach combining conventional toxicological bioassays with predictive biomarkers in native mussels might represent an additional tool for Control Agencies and Administrators dealing with management of human risk and economical damage caused by STX secreted by harmful algal blooms ( Beliaeff and Burgeot, 2002 ).…”
