The Effects of Micro & Nano Pollution on Fish Reproduction
This review summarizes how micro- and nano-sized pollutants — including microplastics — enter fish through food, respiration, and direct contact, disrupting reproductive success and causing developmental abnormalities in offspring. The cumulative harm to fish reproduction poses a long-term threat to aquatic population viability, with potential cascading effects up the food chain to humans.
Effects of pollution on freshwater aquatic organisms
This annual review of scientific literature covers 2018 research on the effects of various pollutants on freshwater aquatic organisms, including microplastics, pesticides, pharmaceuticals, and heavy metals. The review highlights the growing body of evidence that multiple freshwater pollutants impair the health, reproduction, and behavior of aquatic species.
Experimental Approaches for Characterizing the Endocrine-Disrupting Effects of Environmental Chemicals in Fish
This review examines experimental approaches used to characterize the endocrine-disrupting effects of environmental chemicals, including microplastics, in fish. Researchers summarize methods spanning molecular, cellular, and whole-organism levels, including gene expression analysis, hormone measurements, and reproductive assays. The study provides a framework for evaluating how pollutants interfere with hormonal regulation in aquatic vertebrates and highlights the value of fish as sentinel species.
Toxicological implications of emerging pollutants on aquatic organisms
Researchers reviewed how a broad range of emerging pollutants — including microplastics, pharmaceuticals, pesticides, and heavy metals — harm aquatic organisms like fish, amphibians, and molluscs. Evidence shows these pollutants trigger oxidative stress, disrupt hormones, impair reproduction, and reduce biodiversity, with the review calling for stronger regulations, better wastewater treatment, and more research on the combined effects of multiple pollutants.
Individual and combined effects of microplastics and diphenyl phthalate as plastic additives on male goldfish: A biochemical and physiological investigation
Male goldfish exposed to both microplastics and the plasticizer chemical DPP (diphenyl phthalate) together showed significant liver damage, disrupted fat and sugar metabolism, and hormonal imbalances including decreased testosterone and increased estrogen. The combined exposure was more harmful than either pollutant alone, demonstrating how microplastics and their chemical additives can work together to disrupt the endocrine system.
Impact of Heavy Metals and Pesticide Contamination on Aquatic Environment and Fish Health: Challenges and Bioremediation Strategies
This review examines the impact of heavy metals and pesticide contamination on aquatic environments and fish health, including the role of microplastics as co-contaminants. The authors discuss how industrialization has increased pollutant levels in water systems, affecting fish physiology and ecosystem balance. The study highlights bioremediation strategies as promising approaches for cleaning up contaminated aquatic environments.
A review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes
This review summarizes how microplastics cause a range of harmful effects in fish, including behavioral changes, brain and immune system damage, oxidative stress, and reproductive disruption through interference with hormone signaling. These findings are relevant to human health because many of the same biological pathways affected in fish also exist in humans, and people consume fish that have accumulated microplastics.
The effects of environmental changes on the endocrine regulation of feeding in fishes
