Analysis of Water Quality in Seawater Samples Collected from Beaches of Istanbul

Abstract

Oceans all throughout the world are becoming more acidic. Due to significant anthropogenic and natural consequences, the acidification of the marginal seas is a more serious threat than it is to the open ocean. Changes in the pH, temperature, level of dissolved oxygen, and salinity of seawater may also be signs of ocean acidification. The current study's objective is to evaluate the water quality in three coastal areas of Istanbul by taking measurements of the physicochemical characteristics over a period of around 3 months. The Marmara coast is a well-liked site for outdoor activities like swimming and fishing in Istanbul, a heavily industrialized and congested metropolis. Bostanci, Kartal, and Maltepe are the most visited swimming beaches on the Anatolian side of the Marmara coast, and the Sea of Marmara is significant for the variety of coastal species. This study looked at certain water quality measures to see if the saltwater quality near the shore was adequate for marine life and human health. The research was conducted from November 2022 to January 2023. The results showed that there is no major risk to human or aquatic life health from the levels of pH, temperature, salinity, and dissolved oxygen in the Sea of Marmara.
