“…Therefore, lower turbidity values are justified due to social isolation and suspension of socio-cultural events to contain the spread of COVID-19 in Brazil ( Aman et al, 2020 ). Corroborating the results of this study, Régis et al (2018) studied the water quality standards of the Capibaribe River, and observed an increase in the water turbidity of the river for the urban region of the municipality, due to chemical pollutants from human action, while the referring region of the forest area ( Fig. 4 ) is due to suspended particles (e.g., organic matter, and clay).…”

“…It is reasonable that other contaminants not measured in the present study might be influencing the detected zebrafish developmental toxicity. There is a lack of information about chemical contaminant concentrations in the upper reaches of the Capibaribe River, but in the lower reaches close to sites S9 and S10 sediments contaminated by metals, PAHs, chlorinated pesticides dichlorodiphenyltrichloroethane and dichlorodiphenyldichloroethylene, and polychlorinated biphenyls were associated with toxicity in laboratory tests to nauplii of the meiofaunal copepod Tisbe biminiensis (Régis et al, 2018), and estrogens have been detected and associated with behavioral effects in male Poecilia vivipara (de Melo et al, 2021).…”

The Capibaribe River provides water to a population of 1.7 million people in the Brazilian northeast, while receiving agricultural runoff and industrial and domestic effluents along its 280 km. The present study evaluated the ecotoxicity of surface waters along ten sites in rural and urban areas using zebrafish (Danio rerio) early‐life stages and related it to water quality indices and chemical abiotic variables. Lethality rates, delays in embryo‐larval development quantified by the general morphology score (GMS), and frequencies of developmental abnormalities were analyzed. A correlation was detected between zebrafish GMS and water quality index (WQI), sensitivity to domestic sewage contamination, and trophic state index, focused on eutrophication. These indices agreed in identifying a spatial pattern of smaller impact in terms of ecotoxicity, domestic sewage contamination, and eutrophication risk at three sites in rural areas (mean GMS 16.9), an intermediate impact at four sites with urban and agricultural influence (mean GMS 16.4), and greatest impacts at three more urbanized sites (mean GMS 14.9). Most frequent developmental abnormalities included noninflation of the swim bladder, delayed hatching, nonprotrusion of the mouth, blood stasis, and nondevelopment of pectoral fins. Toxic NH3 concentrations varied spatially, with higher concentrations in urban sites; and blood stasis correlated positively with NH3, suggesting a causal relationship. Polycyclic aromatic hydrocarbons were detected in both rural and urbanized sites, contributing to detected toxicity. The present study demonstrates the potential of zebrafish early‐life stages as an ecotoxicological model that may contribute to a better understanding of surface water quality and ecotoxicity in tropical river systems.

“…Benthic copepods are used in a range of studies, to evaluate how exposure to chemical stressors can be associated to effects on reproductive success, fecundity, and development of different species, such as the genus Nitocra spp. (Izar et al, 2019;Cariello, 2018;Perina, 2018), Tisbe biminiensis (Araújo-Castro, et al, 2009;Maciel, 2015;Régis, 2018), and Amphiascus tenuiremis (Sikder, 2018; Organisation for Economic Cooperation and Development, 2007). These detritivore filter feeding organisms constitute an important component of the marine trophic chain, linking the energy and biomass flow from the primary producers to the consumers, since they represent relevant dietary items for diverse marine organisms, such as fish (special fingerlings and post larvae) and other crustaceans (Ruppert et al, 1996).…”

Fire suppressors are widely used in firefighting and their chemical composition may present a mixture of perfluorochlorinated surfactants (PFCs), including the perfluorooctane sulfonate (PFOS) which has been internationally banned due to its classification as a persistent organic pollutant (POP). PFCs have been found in environmental matrices and soft tissues of organisms, but the potential effect of such compounds on marine organisms has been overlooked. Here, it was evaluated whether the chronic exposures (i.e., seven days) to the fire suppressors Ageofoam, Cold Fire, Kidde and Argus could affect the reproduction of the copepod Nitocra sp. The tested concentrations consisted of those recommended on the products’ manuals and those ranging between 0.0001% and 1%. For each compound, the effective concentrations to 50% exposed organisms (EC50) and the lowest observed effect concentrations (LOEC) were estimated. All the fire suppressors exhibited high toxicity, causing fecundity reduction. At the recommended dilutions, 100% lethality occurred for all compounds. The EC50 values ranged from 0.00817% - Ageofoam - to 0.03081% - Argus. The LOECs ranged from 0.001% - Ageofoam - to 0.1% - Argus and Kidde; and were much lower than the concentrations recommended for commercial use. The fire suppressors showed high toxicity to the copepod, reducing the reproduction rates, even in very low concentrations, suggesting that the release of such substances in the estuary caused severe effects to the environment. This assessment provides subsides to the environmental regulation of fire suppressors in Brazil, because these compounds do not have national regulations for their use and disposal.
