Summary: The study found that nickel exposure had significant toxic effects on the early development of marine fish, affecting egg size, heart rate, hatchability, deformity rate, and total body length of newly hatched larvae. Embryos were more sensitive to nickel than larvae, with specific genes showing altered expressions in response to nickel exposure.

Summary: Exposure to 17 alpha-ethinylestradiol (EE2) in fish can result in developmental toxicity, including growth retardation, decreased heart rate, delayed eye pigmentation, reduced hatching rate, and impaired larval locomotion. Transcriptional analysis revealed that these impairments are controlled by estrogen receptor and related to eye structure, neuronal and synaptic structure, and behavior. Key factors identified, such as PRKAA2, APOB, EPHB2, OXTR, NR2E3, and POU4F2, could serve as biomarkers for assessing EE2-induced embryo developmental toxicity.

Summary: Previous studies have shown that exposure to polychlorinated biphenyls (PCBs) in fish can lead to alterations in reproductive functions and behavior. However, the effects of embryonic exposure to PCBs or their metabolites on long-term reproductive function in fish have not been studied. In this study, the marine medaka fish was used to assess the reproductive endpoints after embryonic exposure to either PCB 28 or 4'-OH-PCB 65. The results showed that exposure to 4'-OH-PCB 65 feminized the sex ratio and decreased fecundity in the medaka. Additionally, embryonic exposure to 4'-OH-PCB 65 resulted in reduced fertilization, hatching success rate, and sperm motility. To explain these effects, transcriptomic analysis of the gonads was performed, revealing differential expression of genes involved in reproductive functions. Therefore, the long-term reproductive toxicity of PCBs and their metabolites should be considered in environmental risk assessment.

Summary: This study investigated the reproductive toxicity of chronic diflubenzuron exposure in female marine medaka. The results showed that exposure to diflubenzuron resulted in reduced reproductive performance, altered ovarian histopathology, inhibited development of the F1 generation, and changes in hormone levels and gene expression. These findings highlight the importance of investigating the potential environmental risks of diflubenzuron in marine ecosystems.

Summary: This study investigated the effects of bisphenol compounds (BPA, BPS, BPF, and BPAF) on the early growth and development of aquatic organisms using marine medaka larvae. The results showed that these compounds have toxic effects on the cardiovascular system of the larvae, causing neurotoxicity and endocrine disruption. Functional enrichment analysis suggested that the main toxic effects of bisphenols on marine medaka larvae targeted the liver and heart, mainly affecting lipid metabolism and cardiac muscle contraction. This study provides a theoretical foundation for evaluating the toxicological effects of bisphenols on the early development of aquatic organisms.

Summary: This study found that different types of microplastics did not significantly affect the locomotor activity of marine medaka larvae, while exposure to triphenyl phosphate (TPhP) resulted in decreased mobility. However, in the binary mixture exposure of TPhP and microplastics, the presence of microplastics was able to reverse the decrease in mobility caused by TPhP.

Summary: The study showed that TDCIPP and TPhP have developmental toxicity in marine organisms, leading to shortened body length, fin deformities, and spinal curvature in Oryzias melastigma, posing potential risks to marine fish and ecosystems. Additionally, although both chemicals caused similar bone toxicity, they had different effects on the expression of bone developmental genes such as bmp4, bmp2, and runx2.

Summary: The study showed that MPs can increase the bioaccumulation of Phe in aquatic organisms, reduce reproductive capacity, and exacerbate toxicity effects. Maternal uptake of Phe can be transferred to offspring, with accumulation increasing with MPs concentrations. MPs may amplify the adverse effects of organic pollutants on the health and population stability of marine fishes.

Summary: The study revealed that environmentally relevant concentrations of 4-MBC have toxic effects on Tigriopus japonicus, with increasing salinity levels further enhancing its lethal, developmental, and reproductive toxicities. This may be attributed to the higher salinity levels increasing the uptake rate constant and bioconcentration factor of 4-MBC, exacerbating the oxidative stress induced by 4-MBC exposure in T. japonicus.

Summary: This study investigated the effects of salinity fluctuations on the Antarctic harpacticoid copepod Tigriopus kingsejongensis, finding that female copepods were more tolerant to hypo- and hypersalinity compared to males. Lifespan was significantly shortened under hypo- and hypersalinity, but there was no significant difference in sex ratio between salinity treatments. Multigenerational experiments showed that exposure to certain salinities reduced body length compared to control.

Summary: This study evaluated the acute and chronic effects of dichlofluanid, a broad-spectrum fungicide, on the marine mysid Neomysis awatschensis. The results showed higher sensitivity to dichlofluanid in juvenile mysids compared to adults, with lower survival rate and reduction in food consumption. Exposure to dichlofluanid induced oxidative imbalance and affected enzymatic activities. Chronic exposure to sublethal concentrations of dichlofluanid resulted in decreased survival rate in juveniles and growth retardation in multigenerational monitoring. Consistent exposure to environmentally relevant concentrations of dichlofluanid could be detrimental to the mysid population.

Summary: This study analyzed the acute and chronic effects of diuron on the harpacticoid copepod Tigriopus japonicus. The acute exposure experiment showed that 1/10 LC50 diuron significantly reduced the copepod's feeding rate and acetylcholinesterase activity. Chronic exposure revealed adverse multigenerational effects, with the second generation being the most sensitive to diuron.
