Microplastics Detected in Commercial Fish in the Gulf of Izmir
A recent study conducted by scientists from a university in western Turkey has revealed the presence of microplastics in the digestive systems of various commercial fish species in the Gulf of Izmir. The researchers found that microplastics were more abundant near the water surface compared to the bottom of the sea.
Research Findings and Statistics
The study involved examining fish such as mackerel, red mullet, sea bream, tern, sea bass, coral, mullet, horse mackerel, sardine, mackerel, and shad in the Gulf of Izmir. Microplastics were detected in the digestive systems of these fish, with sizes ranging from 101 to 4,901 micrometers.
Percentage of Microplastics in Different Fish Species
Among the fish species examined, microplastics were found in varying percentages. For instance, microplastics were detected in 55% of mullet fish, 50% of mackerel, 42% of horse mackerel, 41% of bream, and so on.
Color Variations of Microplastics
When sorted by color, the study revealed that black microplastics were the most common at 64.9%, followed by red at 10.4%, blue at 9.1%, green at 7.8%, white at 6.5%, and transparent microplastics at 1.3%.
Impact of Microplastics on Marine Life
Kenan Gedik, an academic involved in the study, emphasized that various everyday plastics like food packaging, bags, disposable items, and toys contribute to the presence of microplastics in marine life. He warned that the increasing plastic pollution poses a significant threat to marine ecosystems globally.
Accumulation of Microplastics in Fish Species
The researchers examined different fish species living in various habitats within the Gulf of Izmir and found that more microplastics accumulated in pelagic fish species compared to demersal ones. The predominant type of microplastics detected was polyethylene.
Health Risks Associated with Microplastics
Gedik highlighted that microplastics can obstruct fish digestive tracts, affect nutrient absorption, and act as carriers for pollutants. He warned that these pollutants can enter the food chain, leading to imbalances in the marine ecosystem and potential health risks for humans.
Human Exposure to Microplastics
Gedik also pointed out that humans can be exposed to microplastics through consuming contaminated fish, raising concerns about the health implications of these synthetic particles.
