“…HEDAYATI; JAHANBAKHSHI (2013), que observaram o efeito do óleo diesel em juvenis de H. huso, registraram a presença de linfócitos, neutrófilos e eosinófilos no tecido sanguí-neo, mostrando que a exposição dos juvenis por 48 horas ao xenobiótico ocasionou redução de linfócitos e aumento de neutrófilos. Logo, o derramamento ou descarte inadequado dos derivados de petróleo no ambiente aquático pode ocasionar inflamação nos organismos, alterando possivelmente os parâmetros hematológicos dos peixes (RODRIGUES et al, 2010;SIMONATO et al, 2013). Assim, o aumento da glicemia com a crescente adição de óleo diesel é uma resposta fisiológica dos peixes ao desequilíbrio homeostático, na tentativa de se adaptar às condições adversas às quais estão submetidos.…”

“…O descarte ou escape desse combustível no ambiente aquático pode afetar severamente os organismos existentes, ocasionando alterações teciduais e hematológicas, podendo levar à morte das espécies mais sensíveis (SIMONATO et al, 2008;SIMONATO et al, 2013;RODRIGUES et al, 2010).…”

“…Os riscos gerados por esses compostos remetem à preocupação com o seu derramamento ou descarte residual no meio hídrico (KUBACH et al;EGRES et al, 2012), principalmente os oriundos das embarcações pesqueiras, que, mesmo quando descartados em pequena quantidade, por ocorrer de maneira contínua, atuam de forma crô-nica nos organismos aquáticos (SIMONATO et al, 2008;SIMONATO et al, 2013). Essa exposição toxicológica pode alterar o comportamento, a morfologia, o metabolismo, o crescimento, a reprodução e o sistema imunológico dos peixes (RODRIGUES et al, 2010;SIMONATO et al, 2013).…”

ABSTRACT:This study aimed to evaluate the stress and changes in white blood cell count of juveniles Oreochromis niloticus subjected to acute toxicity of diesel oil. The toxicity was evaluated in a completely randomized design with five dilutions (20, 25, 30, 35 and 40%) and one control, both with three replicates. For the assessment of blood glucose levels and changes in white blood cell count, blood was drawn by caudal puncture of the dying fish. It was concluded that diesel oil can present risks to aquatic ecosystem, causing toxicity and physiological changes to fish. KEYWORDS: physiological changes; fish; derived oil; leukogram. RESUMO:O presente trabalho teve como objetivo avaliar o estresse e as alterações no leucograma dos juvenis de Oreochromis niloticus submetidos à toxicidade aguda do óleo diesel. A toxicidade foi avaliada em um delineamento inteiramente casualizado com cinco diluições (20, 25, 30, 35 e 40%) e um controle, ambos com três repetições. Para a avaliação dos níveis glicêmicos e alteração no leucograma, foi retirado sangue por punção caudal dos peixes moribundos. Dessa forma, conclui-se que o óleo diesel pode apresentar riscos ao ecossistema aquático, provocando toxicidade aos organismos aquáticos e alterações fisiológicas.

“…This response consists of a chain of reactions promoted by a stressor, starting in fish with the neuroendocrine responses, called primary responses, including the rapid release of hormones into the circulation, such as catecholamines and cortisol (Belanger et al 2001). This is followed by the secondary stress response, which includes various biochemical and physiological changes mediated by hormones liberated in the primary response and leads to hematological, osmo-ionic, and metabolic changes (Oliveira et al 2011;Simonato et al 2013). These events will lead to the tertiary response, resulting in a decrease of growth performance or reproductive capacity, as well as the ability to cope with other stressful situations (Wendelaar Bonga 1997).…”

Fish normally undergo periods of food deprivation that are longer than non-hibernating mammals. In aquacultured rainbow trout (Oncorhynchus mykiss), it is unclear how fasting may affect their physiological adaptative response, especially when they are normally fed daily. In addition, that response may vary with temperature, making it necessary to express fasting duration in terms of degree days. In the current study, trout were fasted for 5, 10, and 20 days (55, 107, and 200 degree days (°C d), respectively). To assess the physiological response of fish to fasting, different biometric, blood, plasma, and metabolic parameters were measured, as well as liver fatty acid composition. The fish weight, condition factor, and the hepato-somatic index of 5-day fasted trout were not significantly different from those of control fish. Gastric pH increased as fasting progressed while plasma concentrations of glucose, triglycerides, and total proteins decreased significantly after 10 days of fasting, while the percentage of non-esterified fatty acids increased. There were no significant differences in plasma ions (sodium, potassium, and calcium), except for chloride ion which decreased after 5 days of fasting. Liver glycogen decreased after 5 days of fasting while glycogen concentration in muscle did not decrease until 20 days of fasting. Liver color presented a higher chroma after 5 days of fasting, suggesting a mobilization of reserves. Finally, acetylcholinesterase activity in the brain was not affected by food deprivation but increased after 10 days of fasting in liver and muscle, suggesting the mobilization of body reserves, but without severely affecting basal metabolism.

Fire suppression agents are recommended for extinguishing fires by flammable liquids and frequently end in water bodies, combined with the fuels. There is a lack of toxicity information on these commercial formulations and the effects of mixtures of fire suppression agents and fuels. The aim of the present study was to evaluate the toxic effects of different fire suppression agents, the gasoline water‐soluble fraction (GWSF), and mixtures of each fire suppression agent and GWSF. Individual tests were performed with Daphnia similis and Artemia sp.; the most toxic fire suppression agents to D. similis and Artemia sp. were F‐500®, Cold Fire®, Agefoam®, and Kidde Sintex® 1%; the GWSF was the least toxic. The concentration addition model was used to predict the mixture effects and evaluate synergism/antagonism, dose ratio dependence, and dose level dependence. Cold Fire with GWSF showed dose level deviation to D. similis, marked mainly by synergism; for Artemia sp., the dose ratio pattern was predicted, with a synergistic response mainly by Cold Fire. Agefoam and GWSF behaved additively for D. similis and dose ratio for Artemia sp., with synergism being caused by Agefoam. Kidde Sintex 1% with GWSF were dose ratio for both organisms, with Kidde Sintex 1% being responsible for synergism. Our results show that some mixtures of fire suppression agents and GWSF may cause toxicity to aquatic organisms, posing risk in a real environmental scenario, such as a major fire combat.
