Abstract
Turkish coastline neighbor to the Mediterranean Sea faces serious problems such as eutrophication and diffuse pollution. Among diffuse pollution, the leading actor is intensive agriculture. This research focuses on four developed cities, Antalya, Mersin, Adana, and Hatay, along the Turkish Mediterranean shoreline. The inadequate sewage system and insufficient treatment plants lead to eutrophication in populated cities. In the year 2017, in Turkey's Mediterranean region, Aksu, Manavgat, Göksu, Seyhan, Ceyhan, and Asi rivers were monitored. Concentration values for BOD5, Total Phosphorus, Nitrite Nitrogen, and Nitrate Nitrogen parameters were determined. This study observes the pollution status of the rivers according to the Turkish Water Pollution Control Regulation. One sample T-Test determined the actual pollution potentials of the rivers. Besides, uncontrolled heavy metal and toxic emissions from industry are essential problems.
Highlights
The Mediterranean Sea is under thread of wastewater discharges from municipalities, industries, rivers
This research underlines the level of pollution and recommends necessary measurements that could be taken against pollution on the Mediterranean Sea along Turkey’s shoreline
Surface Water Quality Management Regulation (SWQMR) is a regulation to determine all aspects of water pollution control, river, lake, and groundwater quality, protection zones for water reservoirs, discharge principles, domestic and industrial wastewater discharge standards
Summary
The Mediterranean Sea is under thread of wastewater discharges from municipalities, industries, rivers. Another threat is the oil seep, which is common in Hatay due to petroleum transport and ship maintenance [1]. This research underlines the level of pollution and recommends necessary measurements that could be taken against pollution on the Mediterranean Sea along Turkey’s shoreline. It is to highlight the most critical issues related to pollution in the Mediterranean Sea. The leading transboundary problems of the Mediterranean Sea are nutrient-enrichment/eutrophication, changes in marine living resources, diffuse pollution, and biodiversity/habitat changes [2]. Diffuse pollution involves actual diffuse pollution and a large number of contaminated dispersed, usually single, minor, spot sources [3]. Municipal and industrial wastewaters are often combined and discharged directly into the Mediterranean Sea
