Initial Discovery of Microplastic Presence in the Gastrointestinal Tract of Certain Fish Species in Al-Hoceima Bay
Summary
Fourier Transform Infrared spectroscopy was used to assess microplastic presence in the gastrointestinal tracts of 90 mackerel and gilthead sea bream from Al-Hoceima Bay in the Mediterranean, finding microplastics in 33% of fish overall. Occurrence was 26% in mackerel and 40% in sea bream, highlighting significant contamination in a key Mediterranean fishing area.
The accumulation of plastic waste in ocean environments is a critical ecological issue impacting marine wildlife and human health. This study assesses the presence of microplastics in the gastrointestinal tracts of fish from Al-Hoceima Bay, a key part of the Mediterranean marine ecosystem. Using Fourier Transform Infrared (FT-IR) spectroscopy, we analyzed 90 individuals from two different species, finding that 33% of the examined fish contained microplastics. Specific occurrences were 26% in mackerel and 40% in gilthead sea bream. These findings highlight significant contamination even in commercial fishing areas, raising urgent questions about the long-term ecological effects and health risks. Therefore, the need for effective plastic waste management policies is critical to protect our marine ecosystems and food safety.
