Monitoring, pollution pattern and sources of litter in coastal zones in Tunisia and Germany

Key Points

The study aims to identify key indicators of litter pollution in coastal zones of Tunisia and Germany.
Conducted field monitoring of beach litter in Tunisia and Germany
Analyzed composition and sources of litter, focusing on plastics
Performed biodegradability tests on various materials
In Tunisia, 54-70% of beach litter is plastic, predominantly linked to tourism activities
Comparison with Germany revealed significant management gaps in litter control
Biodegradability tests indicated palm leaves, sugar cane, and paper degrade faster than PLA, CPLA, and PS

Abstract

Marine litter, especially plastics, poses a major threat to marine ecosystems. This study focused on Tunisia and Germany, identifying key indicators through field monitoring and analysis. In Tunisia, beach litter was mostly plastic (54–70%), mainly from tourism. A benchmark with Germany highlighted management gaps. Biodegradability tests showed palm leaf, sugar cane, and paper degrade faster than PLA, CPLA, and PS. Results stress the need for data-driven strategies to reduce coastal pollution effectively.
