Toxic Effects of Microplastics (Polyethylene) Exposure on Neurotransmitter, Stress Indicators and Immunity in Korean Bullhead, Pseudobagrus Fulvidraco

Physiological Alterations and Immune Modulation in Fish Exposed to Microplastics

AI summary · Read the abstract

Researchers reviewed the physiological and immunological effects of microplastic exposure in fish, finding that these particles smaller than 5 mm induce a range of biological disruptions including immune modulation, oxidative stress, and systemic health impacts with broader implications for aquatic ecosystem integrity.

Toxicity Impact of Polyethylene Microplastics on Biochemical Parameters and Oxidative Stress in Benni Fish (Barbus sharpeyi)

AI summary · Read the abstract

Benni fish exposed to increasing concentrations of polyethylene microplastics showed significant liver enzyme disruption, elevated cholesterol and triglycerides, and clear signs of oxidative damage in their cells. These dose-dependent biochemical changes suggest that microplastic exposure causes systemic physiological stress in fish, raising concerns about the health of species humans consume.

Polyethylene Microplastics Induce Concentration- and Time-Dependent Hematophysiological Impairment and Oxidative Stress Following Tissue Accumulation in Rock Bream (Oplegnathus Fasciatus)

Microplastic Toxicity in Aquatic Organisms and Aquatic Ecosystems: a Review

AI summary · Read the abstract

Researchers reviewed how microplastics move through aquatic food webs, finding evidence that these particles accumulate across trophic levels, but noted that most toxicity studies are conducted in labs rather than real ecosystems, leaving major gaps in understanding the true ecological and human health risks.

Impact of Microplastics on Reproductive and Physiological Aspects of Aquatic Inhabitants

AI summary · Read the abstract

Researchers reviewed how microplastic exposure affects reproduction and physiology in freshwater aquatic organisms, finding that plastic particles disrupt hormonal signaling, reduce fertility, and impair development across a range of sensitive freshwater species.
