The functional conservation of important selective serotonin reuptake inhibitor (SSRI) targets in non-target organisms raises concerns about their potential adverse effects on the ecosystems. Although environmental levels SSRIs like paroxetine (PAR) have risen, knowledge regarding long-term exposure to PAR is limited. This study investigated impact sub-chronic (21 days) two sub-lethal concentrations (40 and 400 μg/L) behaviour adult zebrafish different scenarios: basal activity (under dark light conditions), stress response (evoked by sudden transitions) recovery. A new framework was employed for integrative fish's swimming performance based innate ability respond shifts. Several swimming-associated parameters (e.g., total distance, time inactivity, angles) thigmotaxis were monitored an integrated analysis each scenario. Data revealed reduced activity, impaired behavioural alterations recovery PAR-exposed fish. An anxiolytic effect particularly noticeable fish at μg/L (from light) dark) exposed 40 μg/L. detected PAR-induced modifications suggest a disruption brain glucocorticoid signalling that may implications individual level changing responses predators), with repercussions population community levels. Therefore, applied protocol proved sensitive detecting changes induced PAR.

Sex-specific effects of psychoactive pollution on behavioral individuality and plasticity in fish

Abstract The global rise of pharmaceutical contaminants in the aquatic environment poses a serious threat to ecological and evolutionary processes. Studies have traditionally focused on collateral (average) effects psychoactive pollutants ecologically relevant behaviors wildlife, often neglecting among within individuals, whether they differ between males females. We tested sex-specific behavioral individuality plasticity guppies (Poecilia reticulata), freshwater species that inhabits contaminated waterways wild. Fish were exposed fluoxetine (Prozac) for 2 years across multiple generations before their activity stress-related behavior repeatedly assayed. Using Bayesian statistical approach partitions we found males—but not females—in fluoxetine-exposed populations differed less from each other (lower individuality) than unexposed males. In sharp contrast, observed females—but males—whereby exposure even low levels resulted substantial decrease (activity) increase (freezing behavior) Our evidence reveals pollution has individual fish, suggesting females might be equally vulnerable pollutants.

Exploring the Impact of Naphthalene (Polycyclic Aromatic Hydrocarbons) on Anabas testudineus (Bloch) through Dose-Specific Bioenzymological Analysis

ACS Omega, Год журнала: 2024, Номер 9(13), С. 14923 - 14931

This study addresses the increasing concern about naphthalene, a polycyclic aromatic hydrocarbon (PAH), highlighting its growing threats to environment and aquatic life. The research examines impact on Anabas testudineus (Bloch) through detailed dose-specific bioenzymological analysis. Experimental fish groups were exposed T1 (0.71 mg/L) T2 (1.42 naphthalene concentrations, representing 25 50% of LC50 value, respectively, over 1–21 day period. Following experiment, water samples underwent physicochemical analysis, while tissues examined for diverse parameters. Among these parameters, aspirate aminotransferase (AST) alanine (ALT) serve as crucial indicators monitoring physiological status addressing pollution induced by PAHs, especially naphthalene. Statistical significance was observed in morpho-pathological changes erythrocyte alterations, particularly presence tear-drop appearance (Tr) positively interacting with swelled cells (Sc), vacuolated (Va), sickle (Sk) (P < 0.05). These findings highlight significant biomarker response exposure.

Are early and young life stages of fish affected by paroxetine? A case study with Danio rerio

The Science of The Total Environment, Год журнала: 2023, Номер 900, С. 165706 - 165706

Paroxetine (PAR) is a selective serotonin reuptake inhibitor (SSRI) antidepressant increasingly detected in surface waters worldwide. Its environmental presence raises concerns about the potential detrimental effects on non-target organisms. Thus, this study aimed to increase knowledge PAR's impacts, assessing of commercial formulation (PAR-c) and active ingredient (PAR-a) fish. Therefore, short-term exposure PAR-c PAR-a were assessed zebrafish (Danio rerio) embryos/larvae determine most toxic [through median lethal (LC50) effective concentrations (EC50)]. induced morphological abnormalities (scoliosis) dose-dependent manner from 96 hours post-fertilization onwards, suggesting involvement fully functional biotransformation system. As exhibited higher toxicity, it was selected be tested subsequent stage (juvenile stage), which more sensitive (lower LC50). significantly decreased fish swimming activity disrupted stress response. Overall, results highlight ability adversely affect performance, an effect that persisted even after ceases (21-day depuration), may impair individual fitness.

Parental exposure to antidepressants has lasting effects on offspring? A case study with zebrafish

Fish have common neurotransmitter pathways with humans, exhibiting a significant degree of conservation and homology. Thus, exposure to fluoxetine makes fish potentially susceptible biochemical physiological changes, similarly what is observed in humans. Over the years, several studies demonstrated potential effects on different species at levels biological organization. However, parental unexposed offspring remain largely unknown. The consequences 15-day relevant concentrations (100 1000 ng/L) were assessed using zebrafish as model organism. Parental resulted early hatching, non-inflation swimming bladder, increased malformation frequency, decreased heart rate blood flow, reduced growth. Additionally, behavioral impairment was also found (reduced startle response, basal locomotor activity, altered non-associative learning during stages negative geotaxis scototaxis, thigmotaxis, anti-social behavior later life stages). These alterations are consistent anxiety, increase expression monoaminergic genes slc6a4a (sert), slc6a3 (dat), slc18a2 (vmat2), mao, tph1a, th2, neurotransmitters. Alterations behavior, genes, persisted until adulthood. Given high neuronal between data show possibility transgenerational multigenerational pharmaceuticals' exposure. results reinforce need for fish, under realistic scenarios, provide insights into impact these pharmaceuticals.

The Antidepressant, Sertraline, Impacts Growth and Reproduction in the Benthic Deposit Feeder, Tubifex Tubifex

Опубликована: Янв. 1, 2024

Among emerging contaminants, pharmaceuticals are considered one of the most pertinent substances that may threaten aquatic ecosystems. Pharmaceuticals designed to be directed at specific metabolic- and molecular pathways. Thus, they assumed still biologically active when entering ecosystem result in unpremeditated impacts on non-target organisms. One widely used selective serotonin reuptake inhibitors, sertraline (an antidepressant), is regularly found environments. However, knowledge about effects, particular, sediment-associated benthic invertebrates limited. We examined chronic exposure (28d) (3.3, 33, 330 μg/g dw sed.) survival, growth reproduction deposit-feeding oligochaete, Tubifex tubifex. Sertraline significantly decreased T. tubifex survival growth. Worms exposed high concentrations (330 μg/g) had a lower rate reproduction, as indicated by number cumulated cocoons. an environmentally relevant concentration (3.3 ug/g) but maintained similar control. The implications adult worms presumably required more energy for maintenance detoxification, reducing available This represents trade-off between In contrast, allocated slightly increasing cocoons produced quantity quality offspring impacted fewer juveniles were treatment than Overall, results indicate bioavailable negatively growth, reproduction.
