Settleable atmospheric particulate matter affects cardiorespiratory responses to hypoxia in Nile tilapia (Oreochromis niloticus)

Settleable atmospheric particulate matter affects the swimming performance and aerobic metabolic rate of Nile tilapia (Oreochromis niloticus)

“…Industrial activity may vary seasonally, influencing SePM deposition (Santos et al, 2017;Souza et al, 2019). Therefore, we sampled the contaminant from a pool of raw SePM collected over a year in order to assure experimental repeatability (De Angelis et al, 2022;Soares et al, 2022).…”

“…Similar to previous experiments, we used 1 gL -1 of raw SePM mass to produce environmentally realistic contamination in the exposed group (De Angelis et al, 2022;Soares et al, 2022), this level of contamination is similar to that observed in estuarine waters close to Vitória Bay observed in environmental records (aquatic environment) and reported by the Institute of the Environment and Water Resources for the estuarine area near the city of Vitória, ES -Brazil (IEMA, 2021;Santos et al, 2017;Souza et al, 2013). Arrivabene et al (2015) reported SePM in the estuarine waters of Santa Cruz and Vitória Bay, which is related to air-water cross-contamination from metallurgical activity.…”

“…Although, recent publication has revealed potential risk to fish biota (e.g., Soares et al, 2022De Angelis et al, 2022, the presence of metallic particles from APM deposition (sedimentable APM -SePM) in water bodies has not been properly monitored.…”

“…In particular, SePM had effects that would compromise blood oxygen-carrying capacity, causing a reduction in hematocrit, erythrocyte numbers, and mean corpuscular hemoglobin concentration (Soares et al, 2022). Moreover, exposure to SePM also caused gill damage and ventilatory alterations in the same species (De Angelis et al, 2022). These findings indicate that SePM may cause limitations to physiological performance when aerobic metabolic demand increases, with consequences for activities such as swimming, feeding, reproducing, and diverse other components of population functioning.…”

Sensoriamento Remoto De Material Particulado E Aerossóis: Análise Cienciométrica

“…O material analisado apresenta origem difusa, uma vez que a área urbana foi o local de coleta, sendo identificados diversos componentes químicos -Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Mn, Fe, Ni, Cu, Zn, Pb. Outro grupo de pesquisadores, Souza et al (2021); Soares et al (2022); De Angelis et al (2022) e Adorno et al (2023), se dedicaram à análise do MPA depositado diariamente no estado do Espírito Santo, na região industrial, e registraram a presença dos seguintes componentes químicos: Fe, Al, Mn, Cu, Ti, Pb, Sr, Cr, Ni, V, Ce, Zr, La, Y, As, Mo, Rb, Se, Nb, W, Cd, Ag, Bi, Ba, Sn.…”
