Genotoxicity and Metabolic Changes Induced Via Ingestion of Virgin and Uv-Aged Polyethylene Microplastics by the Freshwater Fish Perca Fluviatilis

Ecotoxicological Consequences of Microplastics in Aquatic Life

AI summary · Read the abstract

Researchers reviewed how microplastics — tiny plastic particles under 5mm — harm aquatic ecosystems, documenting that fish, invertebrates, and other marine life can ingest them, leading to physical damage, toxic chemical exposure, and disruptions to feeding and reproduction.

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.

Acute Effects of Size Dependent Low-Density Polyethylene Microplastics on Zebrafish

AI summary · Read the abstract

Zebrafish embryos exposed to low-density polyethylene microplastics for 48 hours accumulated particles in their gut, experienced reduced hatching rates, increased heart rates, and significant tissue damage, with smaller particles causing the most harm. These acute effects in a widely used model organism suggest that even brief early-life exposure to plastic particles can disrupt normal development.

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.
