Ramírez-Olivares AI, Vargas-Abúndez JA, Capparelli MV. Microplastics impair the reproductive behavior and life history traits of the amphipod Parhyale hawaiensis. MARINE POLLUTION BULLETIN 2024; 205:116630. [PMID: 38925027 DOI: 10.1016/j.marpolbul.2024.116630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/15/2024] [Accepted: 06/16/2024] [Indexed: 06/28/2024]
Abstract
We investigated the distribution and effects of waterborne microplastic (MP) (polyethylene microspheres, 53-63 um) on the emergent model for ecotoxicology, the amphipod Parhyale hawaiensis, during 30 days of exposure. The following life-history traits were measured: (1) survival, (2) specific growth rate (SGR), (3) reproductive performance (precopulatory pairing behavior, fecundity, and time to release neonates), (4) molting frequency, (5) F1 newborn offspring survival and (6) MP bioaccumulation. No significant mortality or molt was seen in any of the treatments. MP caused a reduction in SGR, being more pronounced in females. The time for precopulatory pairing was 3-fold longer in amphipods exposed to MP. Fecundity decreased by 50 %, and the time to release juveniles was 6.7 days longer for amphipods exposed to MP. Finally, neonate survival decreased by 80 % after ten days of release. MP disrupts the reproductive mechanisms and triggers adverse effects on life history traits in P. hawaiensis.

AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2024; 270:106883. [PMID: 38503038 DOI: 10.1016/j.aquatox.2024.106883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 02/08/2024] [Accepted: 02/27/2024] [Indexed: 03/21/2024]
Abstract
The escalating use of silver nanoparticles (AgNPs) across various sectors for their broad-spectrum antimicrobial capabilities, has raised concern over their potential ecotoxicological effects on aquatic life. This study explores the impact of AgNPs (50 μg/L) on the marine clam Ruditapes philippinarum, with a particular focus on its gills and digestive glands. We adopted an integrated approach that combined in vivo exposure, biochemical assays, and transcriptomic analysis to evaluate the toxicity of AgNPs. The results revealed substantial accumulation of AgNPs in the gills and digestive glands of R. philippinarum, resulting in oxidative stress and DNA damage, with the gills showing more severe oxidative damage. Transcriptomic analysis further highlights an adaptive up-regulation of peroxisome-related genes in the gills responding to AgNP-induxed oxidative stress. Additionally, there was a noteworthy enrichment of differentially expressed genes (DEGs) in key biological processes, including ion binding, NF-kappa B signaling and cytochrome P450-mediated metabolism of xenobiotics. These insights elucidate the toxicological mechanisms of AgNPs to R. philippinarum, emphasizing the gill as a potential sensitive organ for monitoring emerging nanopollutants. Overall, this study significantly advances our understanding of the mechanisms driving nanoparticle-induced stress responses in bivalves and lays the groundwork for future investigations into preventing and treating such pollutants in aquaculture.

Abstract
Chronic toxicity tests with representative organisms are essential for ecological risk assessment. The circumtropical marine amphipod Parhyale hawaiensis is a promising test organism in ecotoxicology. This study aimed to develop a chronic toxicity protocol for liquid samples testing with P. hawaiensis using reproduction and growth as endpoints. In the proposed protocol, organisms (≤52 days old) are placed in 5 replicates each containing 100 mL of solution, 10 organisms, and 5 g of crushed coral for 42 days of exposure. The protocol was successfully developed but reproduction showed better performance than growth rate. NOECs based on reproduction were determined for zinc (0.10 mg Zn L-1) and 3,4-DCA (0.50 mg L-1), and they are of the same order of magnitude compared with the values of other amphipods. The developed test based on reproduction can be considered a promising tool for hazard characterizations although more tests with different substances are still needed.

Abstract
As a ubiquitous environmental pollutant in China, triazophos (TP) is known to have neurotoxicity, oxidative stress, and reproductive toxicity to mussels. To investigate the molecular mechanisms of TP toxicity, metabolic changes in the digestive glands of Perna viridis in different sexes were examined after treated with 35 μg/L TP. Notably, 158 significant different metabolites (SDMs) were detected in TP-treated mussels and more than half of the SDMs were lipids and lipid-like molecules, which suggested that TP disturbed the lipid metabolism of P. viridis. In addition, metabolites associated with neurotoxicity and reproductive disturbance were also detected in female and male mussels. Moreover, a larger number of SDMs were found in male mussels (120 SDMs) than females (99 SDMs), and 60 common metabolites exhibited consistent variation tendency and similar magnitude in both sexes. The metabolic alternations in female and male mussels displayed similar protective mechanisms and also sex-specific responses, male mussels were more sensitive to TP exposure. This research provided new data about the molecular mechanisms of TP toxicity and the gender specific changes in mussels after treated by chemicals.

[PMID: 35944683 DOI: 10.1016/j.chemosphere.2022.135959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 07/14/2022] [Accepted: 08/01/2022] [Indexed: 06/15/2023]
Abstract
Near-shore marine/estuarine environments play an important role in the functioning of the marine ecosystem and are extremely vulnerable to the presence of chemical pollution. The ability to investigate the effects of pollution is limited by a lack of model organisms for which sufficient ecotoxicological information is available, and this is particularly true for tropical regions. The circumtropical marine amphipod Parhyale hawaiensis has become an important model organism in various disciplines, and here we summarize the scientific literature regarding the emergence of this model within ecotoxicology. P. hawaiensis is easily cultured in the laboratory and standardized ecotoxicity protocols have been developed and refined (e.g., miniaturized), and effects of toxicants on acute toxicity (Cd, Cu, Zn, Ag, ammonia, dyes, pesticides, environmental samples), genotoxicity as comet assay/micronuclei, and gene expression (Ag ion and Ag nanoparticles) and regeneration (pesticides) have been published. Methods for determination of internal concentrations of metals (Cu and Ag) and organic substances (synthetic dye) in hemolymph were successfully developed providing sources for the establishment of toxicokinetics models in aquatic amphipods. Protocols to evaluate reproduction and growth, for testing immune responses and DNA damage in germ cells are under way. The sensitivity of P. hawaiensis, measured as 50% lethal concentration (LC50), is in the same range as other amphipods. The combination of feasibility to culture P. hawaiensis in laboratory, the recent protocols for ecotoxicity evaluation and the rapidly expanding knowledge on its biology make it especially attractive as a model organism and promising tool for risk assessment evaluations in tropical environments.

Abstract
Triazophos (TP) is a widespread pollutant in aquatic environments. A sex-specific metabolic response in green-lipped mussel Perna viridis to TP exposure was observed in our previous study, and this led us to investigate the mechanisms associated with its toxicity. P. viridis were subjected to chronic exposure (15 days) to TP at 35 μg/L to compare the sex-biased transcriptomic profiles in the gonads of male and female mussels. We identified 632 differentially expressed genes (DEGs) (348 up-regulated and 284 down-regulated) in TP-exposed males, and only 61 DEGs (9 up-regulated and 52 down-regulated) in TP-exposed females. Many DEGs were found to be involved in the nervous, reproductive endocrine, oxidative stress, and immune systems of P. viridis. Additionally, enzymatic activity analysis indicated TP induced neurotoxic effects and oxidative damage to the mussels. Our results demonstrate that the stress response and molecular mechanisms of TP toxicology are different between female and male mussels.

Abstract
Arthropods are the most abundant and diverse animals on earth. Among them, pancrustaceans are an ancient and morphologically diverse group, comprising a wide range of aquatic and semi-aquatic crustaceans as well as the insects, which emerged from crustacean ancestors to colonize most terrestrial habitats. Within insects, Drosophila stands out as one of the most powerful animal models, making major contributions to our understanding of development, physiology and behavior. Given these attributes, crustaceans provide a fertile ground for exploring biological diversity through comparative studies. However, beyond insects, few crustaceans are developed sufficiently as experimental models to enable such studies. The marine amphipod Parhyale hawaiensis is currently the best established crustacean system, offering year-round accessibility to developmental stages, transgenic tools, genomic resources, and established genetics and imaging approaches. The Parhyale research community is small but diverse, investigating the evolution of development, regeneration, aspects of sensory biology, chronobiology, bioprocessing and ecotoxicology.

Abstract
Silver nanoparticles (AgNPs) are known to cause ecotoxic effects, but there are no existing derived ambient water quality criteria (AWQC) for these nanomaterials to protect freshwater aquatic life due to insufficient toxicological data. We exposed Hyalella azteca to silver nitrate, citrate-coated AgNPs (citrate-AgNPs), and polyvinylpyrrolidone-coated AgNPs (PVP-AgNPs) in a 10-day and 28-day water-only static renewal system with clean sand as a substrate for the amphipods and compared their point estimates with the United States Environmental Protection Agency (USEPA) AWQC for silver. We observed that all treatments decreased the survival, growth, and biomass of H. azteca, and the order of toxicity was AgNO3 > citrate-AgNPs > PVP-AgNPs. The LC50s of AgNO3, citrate-AgNPs, and PVP-AgNPs were 3.0, 9.6, and 296.0 µg total Ag L-1, respectively, for the acute exposure and 2.4, 3.2, and 61.4 µg total Ag L-1, respectively, for the chronic exposure. Acute and chronic EC20s of citrate-AgNPs ranged from 0.5 to 3.5 µg total Ag L-1 while that of PVP-AgNPs ranged from 31.2 to 175 µg total Ag L-1 for growth and biomass. Both Ag+ released from AgNPs and the nanoparticles contributed to the observed toxicity. The dissolution and toxicity of AgNPs were influenced by surface coating agents, particle size, and surface charge. Most point estimates for AgNPs were above AWQC for silver (4.1 µg L-1) and the lowest concentration (0.12 µg/L) at which Ag is expected to cause chronic adverse effects to freshwater aquatic life. Our study demonstrates that the current AWQC for silver, in general, is protective of freshwater aquatic life against AgNPs tested in the present study.

Abstract
Determining the bioavailability and toxicity mechanism of silver nanoparticles (AgNPs) is challenging as Ag+ is continuously released by external or internal AgNP dissolution in the actual exposure system (regardless of the laboratory or the natural environment). Here a novel pulsed-gradient Ag+ (AgNO3) exposure was conducted with zebrafish (Danio rerio) larvae to simulate dissolved gradient concentrations of Ag+ from polyvinylpyrrolidone (PVP)-coated AgNPs. The accumulation and toxicity of the pulsed-gradient Ag+ (AgNO3) and, in the meantime, the released Ag+ from PVP-AgNPs were predicted using a toxicokinetic-toxicodynamic (TK-TD) model with obtained Ag+ parameters. In order to further understand the possible mechanism of PVP-AgNP releasing Ag+ in the body, subcellular fractions (S9) of zebrafish were also used to incubate with AgNPs in vitro to mimic the realistic in vivo scenarios. In the TK process, in vivo analysis showed that AgNPs released around twice as many Ag+ into the body than were detected with a single Ag+ pulse-exposure system; this was supported by evidence that subcellular S9 fractions might cause the PVP-AgNPs to lose the capping agent and favor Ag+ release. In the TD process, toxicity (survival rate) was predicted by the total bodily Ag(I) concentration, suggesting that AgNP toxicity in larvae was mainly due to gradually released Ag+ rather than AgNPs themselves. This study helps clarify the role of Ag+ in AgNP toxicity and offers a novel framework by which to investigate the toxicity of metal nanoparticles and corresponding metal ions in biological systems.

Abstract
Regeneration is a widely spread process across the animal kingdom, including many species of marine crustaceans. It is strongly linked to hormonal cycles and, therefore, a great endpoint candidate for toxicology studies. We selected the amphipod Parhyale hawaiensis as test organism, already used in ecotoxicological studies and able to regenerate its body appendages. We are proposing a protocol to use the antenna regeneration as a toxicity endpoint. First, we evaluated differences in time of completion of regeneration in males and females after the amputation of one antenna of 6 months old animals. Then we compared the influence of different testing volumes in the regeneration process (100 and 5 mL). We used as testing substances, dimethyl sulfoxide (DMSO) and diflubenzuron, a chitin synthesis inhibitor. The most suitable protocol consisted of volumes of 5 mL in 12-well microplates, with 1 organism per well, 12 organisms per concentration (1:1 females/males) and test time duration of around 5 weeks. DMSO accelerated regeneration time with a NOEC of 0.06%. Diflubenzuron inhibited the time necessary to its completion with a NOEC of 0.32 μg L-1. We conclude that the Parhyale hawaiensis antenna regeneration protocol proposed here is a potential tool in ecotoxicology, but more studies are required for its validation not only to verify its utility for testing chemicals but also environmental samples.

Abstract
The aim of the present study was the assessment of the sub-chronic effects of silver (AgNPs) and gold nanoparticles (AuNPs) of 40 nm primary size either stabilised with citrate (CIT) or coated with polyethylene glycol (PEG) on the freshwater invertebrate Gammarus fossarum. Silver nitrate (AgNO3) was used as a positive control in order to study the contribution of silver ions potentially released from AgNPs on the observed effects. A multibiomarker approach was used to assess the long-term effects of AgNPs and AuNPs 40 nm on molecular, cellular, physiological and behavioural responses of G. fossarum. Specimen of G. fossarum were exposed for 15 days to 0.5 and 5 µgL-1 of CIT and PEG AgNPs and AuNPs 40 nm in the presence of food. A significant uptake of both Ag and Au was observed in exposed animals but was under the toxic threshold leading to mortality of G. fossarum. Silver nanoparticles (CIT-AgNPs and PEG-AgNPs 40 nm) led to an up-regulation of Na+K+ATPase gene expression. An up-regulation of Catalse and Chitinase gene expressions due to exposure to PEG-AgNPs 40 nm was also observed. Gold nanoparticles (CIT and PEG-AuNPs 40 nm) led to an increase of CuZnSOD gene expression. Furthermore, both AgNPs and AuNPs led to a more developed digestive lysosomal system indicating a general stress response in G. fossarum. Both AgNPs and AuNPs 40 nm significantly affected locomotor activity of G. fossarum while no effects were observed on haemolymphatic ions and ventilation.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2020; 264:114605. [PMID: 32380390 DOI: 10.1016/j.envpol.2020.114605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 04/14/2020] [Accepted: 04/14/2020] [Indexed: 06/11/2023]
Abstract
The adaptive fitness of insect species can be shaped by how males and females respond, both physiologically and behaviorally, to environmental challenges, such as pesticide exposure. In parasitoid wasps, most toxicological investigations focus only on female responses (e.g., survival and especially parasitism abilities), leaving the male contributions to adaptive fitness (survival, locomotion, mate search) poorly investigated. Here, we evaluated the toxicity of the spinosyn insecticide spinosad against the South American fruit fly, Anastrepha fraterculus, and we used the parasitoid wasp Diachasmimorpha longicaudata (Ashmead) to evaluate whether sex-linked locomotory and physiological responses would influence the susceptibility of these organisms to spinosad. Our results revealed that D. longicaudata males were significantly more susceptible (median lethal time (LT50) = 24 h) to spinosad than D. longicaudata females (LT50 = 120 h), which may reflect the differences in their locomotory and physiological (e.g., respiratory) responses to mitigate insecticide exposure. Compared to D. longicaudata females, male wasps were lighter (P < 0.001), walked for longer distances (P < 0.001) and periods (P < 0.001), and exhibited higher sensilla densities in their tarsi (P = 0.008), which may facilitate their intoxication with the insecticide. These findings indicate that male parasitoids should not be exempt from insecticide selectivity tests, as these organisms can be significantly more affected by such environmental challenges than their female conspecifics.
