Assessment of eutrophication in the Berdan River Basin (Türkiye) using various classification tools

ÖZGÜR ÖZBAY | İSMAİL AKÇAY | MEHMET TAHİR ALP

The trophic status of the Berdan River Basin was determined using univariate and multivariate classification tools. The results indicated that the water quality/ trophic status of a downstream section of the Berdan River was characterized as “poor/eutrophic” due to anthropogenic inputs from agricultural, industrial and domestic wastewater discharges. Strong and positive correlations between TRIX values and concentrations of eutrophication parameters suggest that nutrient enrichment of water in the Berdan River during its flow will result in further eutrophication in the coastal region of the N ...Daha fazlası

MEHMET TÜRKERİ | SUAT MARANKOZ | ÖZGÜR ÖZBAY | İSMAİL AKÇAY | MEHMET TAHİR ALP

In this study, dissolved nutrients concentrations were measured monthly at downstream points of the two regional rivers (the Berdan and Göksu rivers) flowing into the Cilician Basin of the North-eastern (NE) Mediterranean Sea.The dissolved nutrients data obtained between September 2021 and August 2022 were used to determine riverine nutrient fluxes. This study showed that spatial and temporal variations were recorded in nutrients concentrations of the two regional rivers with the maximum values consistently recorded in the Berdan River having lower volume fluxes.The annual nutrient inputs of t ...Daha fazlası

Potential Health Risk Assessment for Nitrate Contamination in the Groundwater of Mersin Province, Türkiye

ÖZGÜR ÖZBAY

Though groundwater is one of the most significant natural water sources, its quality is deteriorating due to the anthropogenic pressures that poses health risks for people. In this study, potential health risk assessment for nitrate pollution in groundwater of Mersin Province was determined by commonly using health indices. Study findings indicated that the calculated Hazard Index (HI) values varied between 0.001 and 17.89 for the adults whilst the HI values ranging from 0.001 to 29.87 for the children. The HI values in the groundwater of Erdemli, Göksu and Anamur regions showed low chronic he ...Daha fazlası

Alg terimi genellikle sucul ortamlarda bulunan fotosentetik mikroskobik ve makroskobik tallusa sahip canlılar için kullanılmaktadır. Türkçe’de “alg” karşılığı olarak “suyosunu” benimsenmiş; metin boyunca her iki sözcük de karışık olarak kullanılmıştır. Bu canlılar bir hücreli (kamçılı ve kamçısız), koloniyal (kamçılı ve kamçısız), ipliksi (dallı ve dalsız), sifonlu ya da parankimatik tipte olabilmektedir. Tatlısu ve denizel ortamlarda birincil üretici konumunda olan suyosunlarının ekonomik kullanımı, antimikrobiyal, antitümoral inhibitör aktiviteleri gibi birçok alanda gelişerek tıp ve eczacıl ...Daha fazlası

A study on water quality and trophic state of Akgöl Lagoon (Mersin, Turkey).

MEHMET TAHİR ALP | YUNUS EMRE FAKIOĞLU | ÖZGÜR ÖZBAY

This study aimed to determine the physicochemical characteristics of the water quality and trophic state of Akgol Lagoon located in the eastern Mediterranean. Cluster analysis clearly revealed the € spatial heterogeneity classifying sampling stations as saline and freshwater/brackish water sites. A multivariate analysis of variance followed by principal component analysis supported that salinity was major factor affecting physicochemical water quality variations in the lagoon. As salinity was mainly governed by freshwater inflows depending on agricultural irrigation, it can be proposed that wa ...Daha fazlası
