Floods caused by heavy rain carry significant amounts of pollutants into marine environments. This study evaluates the effect of multiple floods that occurred in the northeastern Mediterranean region in Turkey between December 2016 and January 2017 on the microplastic pollution in the Mersin Bay. Sampling was repeated in four different stations bot...

Turkey became a major importer of global plastic waste after China banned plastic imports on January 1, 2018. Turkey imported only 261,864 tons of plastic waste annually before the ban, but annual imports increased to 772,831 tons by 2020. Turkey recently implemented restrictions on importing plastic waste (quotas, %1 contamination limit, banned mi...

Chapter
The tendency for plastic leakage into the environment is increasing, and researchers struggle to detect the increase of plastic particles in marine environments. However, this situation raises a heated debate about the fate and final destination of missing plastics. The main axis of these discussions is whether the polymer types of plastics are als...
Chapter
Due to the increasing plastic production in the world, it is predicted that the amount of microplastic will increase in the future in all ecosystems in the world, especially in aquatic ecosystems. It is obvious that the negative effects of this pollution will increase in the same way. In this section, the coastal ecosystem, which is an important pa...

Microplastic pollution in the marine environment is a growing concern. Microplastic particles floating or settled in the sea affect both biotic and abiotic components of the marine environment through absorption by biota, entanglement, and colonization. There is also strong evidence that microplastics support microbial growth (also known as plastic...
Article

Contamination of the food and especially marine environment with nano/micro-plastic particles has raised serious concern in recent years. Environmental pollution and the resulting seafood contamination with microplastic (MP) pose a potential threat to consumers. The absorption rate of the MP by fish is generally considered low, although the bioavai...

Conference Paper
Plastic pollution is widely recognized as an important issue for marine environment. Currently, a large proportion of the plastics found in the marine environment are in the form of microplastics (< 5 mm). Microplastics are of most concern because they cannot be easily spotted, and are easily ingested by marine organisms and make their way through...
