Assessment of biological effects of environmental pollution in Mersin Bay (Turkey, northeastern Mediterranean Sea) using Mullus barbatus and Liza ramada as target organisms

The EU Interreg Project “GEREMIA” on waste management for the improvement of port waters: results on monitoring the health status of fish as bioindicator

“…Statistical analysis performed to test the comparison of EROD activity in males and females did not show a significant difference (Mann–Whitney test, p value: 0.06234). The EROD activity levels in Port of Genoa organism were generally higher compared to the baseline EROD activity observed in individuals of the same species collected from reference areas (Corsi et al 2003 ; Gorbi et al 2005 ; Pacheco et al 2005 ; Yilmaz et al 2016 ), and this suggests that the differences observed between sites were caused by exposure to organic compounds, as for instance petrogenic PAHs, known to promote the biotransformation mechanism of cytochrome P450A1 activity (Aas et al 2000 ; Gorbi et al 2005 ; Whyte et al 2000 ). Indeed, EROD levels comparable to those measured in specimens sampled in the Port of Genoa were previously observed in mullets collected in polluted areas characterized by input of contaminants, as basins receiving sewage treatment plant discharge, industrial wastes, and urban outfall (Corsi et al 2003 ; Yilmaz et al 2016 ; Oliveira et al 2020 ).…”

There was no significant difference in EROD activity between species within the same site, for either the port (one-way ANOVA, p value: 0.6972) or the fishpond (one-way ANOVA, p value: 0.0689), confirming the validity of the comparison between sites.…”

Spatial Distribution of Microplastic Contamination in the Invasive Red Sea Mussel Brachidontes pharaonis (Fischer P., 1870) Around the İskenderun Bay

“…In this study, MP accumulation in terms of MPs per ind and MPs per gr were significantly higher in Çevlik station (p<0.05). Significant amount of plastic were transported to coastal part of Çevlik station due to main current system and wind directions (Yılmaz et al, 2022). In addition, many waste deposition peaks were formed around the discharge zone of Orontes River (Yılmaz et al, 2022) which seems to be increase the microplastic amount in the coastal shore.…”

In addition, many waste deposition peaks were formed around the discharge zone of Orontes River (Yılmaz et al, 2022) which seems to be increase the microplastic amount in the coastal shore. In a basic sense, the higher microplastic contamination in the habitat of Brachidontes pharaonis, the higher the microplastic accumulation in the mussel.…”

A study on transboundary governance of marine plastic debris—the case of an adjacent waters between China and Taiwan

“…It is an important material for global manufacturing and industry (Anani et al, 2022). In recent years, marine plastic debris (MPD) has gradually entered the marine ecosystem, and increased the existing pollution pressure of marine creatures (Yılmaz, 2022). Relevant studies found that about 4.8 to 12.7 million metric tons of waste enters the ocean every year, of which about 80% originates from land, including various types of waste most of which are plastic products (Jambeck et al, 2015).…”
