Katar'da kıyı suyu kalitesinin değerlendirilmesi: Toplam askıda katı maddeler, bulanıklık, sıcaklık, pH, tuzluluk ve çözünmüş oksijene odaklanma

Öz

Katar'ın kıyı suları çevre, ekonomi ve sağlık için hayati öneme sahip olmakla birlikte antropojenik ve doğal faktörlerden etkilenmektedir. Toplam askıda katı maddeler (TSS), bulanıklık, sıcaklık, pH, tuzluluk ve çözünmüş oksijen (DO) kıyı sularının sağlığını etkiler. Bu çalışma, Katar'ın kıyı sularındaki bu parametrelerdeki mekansal ve zamansal değişimleri belirlemeyi amaçlamaktadır. Gözlemler 2022 ve 2023 yılları arasında aylık olarak gerçekleştirildi ve sıcaklık, pH, bulanıklık ve tuzluluğu kaydetmek için çoklu prob sensörleri kullanılarak seçilen bölgelere odaklandı. Sonuçlar, sıcaklık ve TSS açısından yedi çalışma bölgesi arasında önemli bir fark olmadığını gösterdi. Tüm bölgelerdeki ortalama sıcaklık aralığı 27,22 ± 5,96 °C ile 28,40 ± 5,97 °C iken, ortalama TSS aralığı 4,64 ± 3,32 mg/L ile 6,64 ± 6,15 mg/L idi. Sonuçlar ayrıca bu çalışma sahaları arasında tuzluluk, pH, DO ve bulanıklıkta önemli farklılıklar (P < 0,05) olduğunu gösterdi. Su kalitesi parametrelerinde önemli mevsimsel farklılıklar vardı. Sıcaklık ve tuzluluk seviyeleri sonbahar ve yaz mevsimlerinde en yüksek, pH ve DO seviyeleri ise ilkbahar mevsiminde en yüksekti. Bulanıklık kış aylarında en yüksekti. Su kalitesi parametreleri arasında karmaşık ilişkiler vardır ve bir parametredeki değişiklik diğerlerini etkileyebilir. Bu sonuçlar, su kalitesini değerlendirirken birden fazla faktörün dikkate alınması gerektiğini vurguladıkları için Katar'daki kıyı kaynaklarının yönetimi açısından çıkarımlar içermektedir. Bu çalışma, su kalitesi parametrelerinin bazı Arap Körfezi bölgelerine yakınlık, kentleşme ve kıyı erozyonu dahil olmak üzere birden fazla faktörden etkilendiğini ileri sürmektedir. Bu gözlemler, ilgili sorunları ele almak ve Katar'daki kıyı suyu kalitesini korumak için kapsamlı yönetim stratejilerine olan ihtiyacı vurgulamaktadır.

Variability of total suspended solids, turbidity, temperature, pH, salinity and dissolved oxygen in Qatar’s coastal waters

Abstract

The coastal waters of Qatar are vital for the environment, economy and health but they are impacted by anthropogenic and natural factors. Among other parameters, Total suspended solids (TSS), turbidity, temperature, pH, salinity and dissolved oxygen (DO) are important parameters in the determination of quality of coastal waters. This study aims to determine the spatial and temporal variations in these parameters in coastal waters of Qatar. The observations were conducted monthly between 2022 to 2023 and focused on selected sites, using multiprobe sensors to record temperature, pH, turbidity and salinity. The results showed that there were no significant differences (P<0.05) between the seven study sites with respect to temperature and TSS. The mean temperature range across all sites was 27.22±5.96°C to 28.40±5.97°C, while the mean TSS range was 4.64±3.32 mg/L to 6.64±6.15 mg/L. Results also suggested that there were significant differences (P<0.05) in salinity, pH, DO and turbidity across these study sites. There were significant seasonal differences (P<0.05) in water quality parameters. Temperature and salinity levels were highest during the fall and summer seasons, while pH and DO levels were highest during the spring season. Turbidity was highest during winter. There are complex relationships between water quality parameters and changes in one parameter could impact others. These results have implications for the management of coastal resources in Qatar, as they highlight the need to consider multiple factors when assessing the water quality. This study suggests that the water quality parameters are influenced by multiple factors, including proximity to some Arabian Gulf regions, urbanization and coastal erosion. These observations highlight the need for comprehensive management strategies to address the pertinent issues and protect the coastal water quality in Qatar.
