Ingestion of rubber tips of artificial turf fields by goldfish
AI summary Read the abstract
Researchers found that rubber crumb infill from artificial turf sports fields can migrate into adjacent waterways and be actively ingested by goldfish, suggesting that synthetic sports fields are a potential pathway for rubber-derived microplastics to enter aquatic ecosystems.
Marine microplastics are one of the global environmental issues. The present study examined whether rubber tips of artificial sports fields could be marine microplastics. We observed the migration of rubber tips from the artificial turf field to the surrounding ditch connected to sewer pipes and then examined the ingestion of rubber tips using the goldfish Carassius auratus. The rubber tips found in sediments in the ditch suggest that the rubber tips could be sent to the river and released into the ocean. The goldfish ingested rubber tips with or without fish feed, and rubber tips were found in the intestine. However, the fish discharged the rubber tips within 48 h after ingestion. These results indicate that ingestion of the rubber tips was not accidental but an active behavior. Therefore, artificial turf sports fields could be a source of marine microplastics and may cause hazardous effects on wild fishes through ingestion.

This Japanese study found that rubber crumb particles from artificial turf fields migrate through drainage systems into waterways and can be actively ingested by goldfish, which retained the particles in their intestines for up to 48 hours. The findings indicate that artificial sports turf is a source of marine microplastic that can be consumed by fish.

AI summary Read the abstract
A Swedish study investigated whether watercourses near artificial turf pitches are a pathway for rubber granulate microplastics to enter the environment, with artificial turf identified as Sweden's second largest source of microplastics. Sediment samples from streams near and far from artificial turfs were compared to assess rubber granulate dispersal.
Environmental risks of breakdown nanoplastics from synthetic football fields
AI summary Read the abstract
Researchers collected drainage water from a synthetic football field and tested whether nanoplastics released from the turf materials were toxic to aquatic organisms. They found that broken-down particles from the rubber granules used as infill were highly toxic to water fleas, particularly chemicals from the granule surfaces. The study raises concerns about the environmental impact of synthetic sports turf on nearby waterways.
