Dataset for Acanthochromis microplastic lab study 2019
AI summary Read the abstract
This dataset supports a 150-day laboratory study examining whether polystyrene microplastic fragments containing common plasticizers (DEHP or DEHT) affected growth, body condition, reproduction, or liver histology in the tropical damselfish Acanthochromis polyacanthus. No detectable effects were found across any measured outcome.
The current study experimentally explored the influence of periodic consumption of polystyrene (PS) microplastic fragments on the body condition and fitness of a tropical marine fish. Adult damselfish, Acanthochromis polyacanthus, were pulse fed microplastic fragments bound with one of two different common plasticizers (DEHP or DEHT) together with virgin-plastic and no-plastic controls. Ingestion of plastic over a 150d period had no detectable effect on growth, indices of body condition, or gonadosomatic indices. Histology of the liver showed no detrimental effects of ingesting any of the plastic treatments on hepatocyte density or vacuolation. Plastic consumption also had no effects on the number of clutches produced over the breeding period, the number of eggs or the survival of the embryos.

Damselfish in distress after consuming plastic
AI summary Read the abstract
This study found that damselfish consuming plastic containing the plasticizer DEHP experienced elevated reactive oxygen species, reduced antioxidant capacity, and behavioral disruptions — suggesting both chemical toxicity and physical blockage contribute to plastic's harm to reef fish.
No Effect of Polystyrene Microplastics on Foraging Activity and Survival in a Post-larvae Coral-Reef Fish, Acanthurus triostegus
AI summary Read the abstract
Exposure to polystyrene microplastics at environmentally relevant concentrations had no measurable effect on foraging activity or survival of juvenile coral reef fish (Acanthurus triostegus) in laboratory trials.
Microplastic consumption elevates fish oxidative stress but does not affect predator-driven mortality
AI summary Read the abstract
Juvenile coral reef fish exposed to polystyrene microplastics for just two days showed increased oxidative stress and cellular damage, especially when the plastics contained the common plasticizer DEHP. However, the microplastic exposure did not affect the fish's ability to escape predators in short-term trials. The study highlights that microplastics may cause hidden health damage to marine organisms even when they appear to function normally.
No effects of plasticized microplastics on the body condition and reproduction of a marine fish
AI summary Read the abstract
Researchers found no significant effects of plasticized microplastics on body condition or reproductive success in a terrestrial animal model, suggesting that plasticizers associated with microplastics may not impair these endpoints at tested concentrations. The findings contribute to understanding the ecological risk of microplastic-associated chemical additives.
Polystyrene microplastics did not affect body growth and swimming activity in "Xenopus laevis" tadpoles
AI summary Read the abstract
This study found that polystyrene microplastics did not significantly affect body growth or swimming behavior in a freshwater fish species ('X-ray fish') at tested concentrations. The results suggest that physical effects of microplastic ingestion may be less pronounced in some freshwater species, though chemical and long-term effects were not assessed.
