ClearPolystyrene microplastics exposure in freshwater fish, Labeo rohita: evaluation of physiology and histopathology
Researchers fed freshwater fish varying levels of polystyrene microplastics for 90 days and found dose-dependent damage to blood health, growth, and organ tissues. Higher microplastic concentrations caused more severe harm to the liver, kidneys, gills, and intestines. The study highlights that microplastics in freshwater systems can accumulate in fish and cause significant health problems, raising concerns about food safety for communities that rely on freshwater fish.
Eco Toxicological Assessment of Micro Plastic Ingestion in Freshwater Fishes: A Case Study on Bioaccumulation and Histopathological Alterations
Researchers assessed microplastic accumulation in three freshwater fish species (tilapia, rohu, catla) from a major river system, finding microplastics in gastrointestinal tracts and associated histopathological damage in gills, liver, and kidneys.
Chronic Toxicity of Microplastics on Fish (Labeo rohita) and Their Impact on the Freshwater Ecosystem: A Case Study of Gangasagar Pond, Darbhanga, India
Researchers investigated microplastic contamination in Gangasagar Pond in India, finding fibers as the most common type, primarily from domestic waste and discarded packaging. Fish in the pond showed microplastics lodged in their gill chambers and mouths, and tissue analysis revealed damage to the stomach and intestines. The study suggests that microplastic pollution in freshwater ecosystems can directly harm fish health through ingestion and physical contact.
ASSESSING HEPATIC TOXICITY IN Labeo rohita (Rohu Fish) INDUCED BY MICROPLASTIC POLLUTION IN FRESHWATER ECOSYSTEMS OF SARGODHA, PUNJAB
This study assessed microplastic pollution in freshwater ponds in Sargodha, Punjab, Pakistan, and investigated physiological effects on Labeo rohita (Rohu fish). PE, PP, and PS microplastics were found in the ponds, and fish showed elevated oxidative stress and hepatic dysfunction consistent with microplastic-induced toxicity.
Toxic effects of microplastic (polyethylene) exposure: Bioaccumulation, hematological parameters and antioxidant responses in crucian carp, Carassius carassius
Researchers exposed crucian carp to polyethylene microplastics at various concentrations and found that the particles accumulated in tissues including gills, gut, and liver. The microplastics altered blood cell counts and disrupted the fish's antioxidant defense system in a dose-dependent manner. The study suggests that even common polyethylene microplastics can cause measurable biological harm in freshwater fish.
Oxidative Stress Induced by Exposure of Microplastics in Labeo Rohita
Exposure to low-density polyethylene (LDPE) microplastics caused dose-dependent oxidative stress in rohu fish (Labeo rohita) over 45 days. The findings suggest that microplastic contamination in aquatic environments can harm fish health through increased free radical damage.
Ecotoxicological effects of low-density polyethylene microplastic on Heteropneustes fossilis: behavioral, hematological, biochemical, and histopathological impacts
Scientists exposed freshwater fish to tiny plastic particles (microplastics) from everyday items like plastic bags and found they caused serious health problems including blood disorders, organ damage, and weakened immune systems. The higher the amount of plastic particles, the worse the damage became to vital organs like gills, intestines, and liver. This matters because these same microplastics are found throughout our food chain and water supply, raising concerns about potential health risks for humans who consume contaminated fish and water.
Effect of plastic microbeads on the development of roho (Labeo rohita)
Researchers fed roho fish (Labeo rohita) varying doses of plastic microbeads over 120 days and found that ingesting microplastics directly stunted their growth, with higher concentrations causing greater harm — providing evidence that microplastic pollution can impair the health of freshwater fish species.
Assessment of dietary polyvinylchloride, polypropylene and polyethylene terephthalate exposure in Nile tilapia, Oreochromis niloticus: Bioaccumulation, and effects on behaviour, growth, hematology and histology
Nile tilapia fish fed three common types of microplastics (PVC, polypropylene, and PET) showed reduced growth, abnormal behavior, blood cell damage, and tissue damage in their gills, liver, and intestines. The harmful effects increased with higher doses of microplastics and varied by plastic type. Since tilapia is one of the most widely consumed fish globally, these findings raise concerns about the health of fish that may carry microplastic contamination to human diets.
[Effects of Microplastic Exposure on Crucian Growth, Liver Damage, and Gut Microbiome Composition].
Researchers exposed crucian carp to varying concentrations of polyethylene microplastics in feed for 30 days and found that low-concentration exposure increased body weight while higher concentrations caused liver damage and altered gut microbiome composition, suggesting dose-dependent effects.
Microplastic Contamination in Edible and Inedible Tissues of Labeo rohita Across Rajasthan and Haryana: A Comparative Assessment
Researchers analyzed microplastic contamination in edible (muscle and skin) and inedible (gut and gills) tissues of freshwater rohu fish (Labeo rohita) from 10 locations in Rajasthan and Haryana, India. MPs were found in all tissue types, including muscle and skin consumed by humans, indicating a food safety concern in these regions.
The effects of exposure to microplastics on grass carp (Ctenopharyngodon idella) at the physiological, biochemical, and transcriptomic levels
Researchers exposed grass carp to microplastics at two concentrations for 21 days and observed liver damage, inhibited growth, and increased oxidative stress. Transcriptome analysis revealed over 1,500 differentially expressed genes related to immune response, metabolism, and cellular stress pathways. The study suggests that microplastic exposure can trigger broad physiological and molecular disruptions in freshwater fish.
Deleterious Effects of Polypropylene Microplastic Ingestion in Nile Tilapia (Oreochromis niloticus)
Researchers fed Nile tilapia daily doses of polypropylene microplastics for 30 days and observed significant health effects including changes in blood cell counts, altered gut bacteria, and tissue damage to the intestines and liver. The higher dose group showed more pronounced effects, including elevated inflammatory markers and signs of oxidative stress. The study provides evidence that chronic ingestion of microplastics commonly found in aquatic environments can cause meaningful harm to a widely consumed fish species.
