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

Nutrient inputs from two major rivers into the cilician basin of the north-eastern Mediterranean Sea.

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

Türkiye Suyosunları Listesi

ÖZGÜR ÖZBAY | MEHMET TAHİR ALP

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

The Economic Importance of Macroalgae

MEHMET TAHİR ALP | DENİZ AYAS

In this study, we discussed algae with economic importance. Information was given about the use of macroalgae in the food industry, medicine and pharmacy, additives, organic agriculture, wastewater treatment, and bioplastic production, which are the areas of use in the economy. The taxa and species used in these areas were investigated. Macroalgae in the seas of our country were examined, and information was given about how they can contribute to the economy

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

Determination of Effects of Seasonal and Sampling Area on Ulva Rigida’s Elemental Composition

MEHMET TAHİR ALP | NAHİT SONER BÖREKÇİ | DENİZ AYAS

Macroalgae is used as a bioindicator for their accumulation capacity of potentially hazardous elements. Ulva spp. was used extensively in previous studies as in the recent study. Along the Mersin coast, sampling was made in four different locations (Çamlıbel Marina, Pozcu Marina, Deniz Feneri, Karaduvar) during the spring and summer seasons between 2015-2016. For elemental analyses, ICP-MS was used, and Mg, Al, K, Ti, Cr, Mn, As, Se, Sr, Mo levels were analyzed in Ulva rigidasamples. The highest level (134960.0 μg g-1) was found in the elemental analysis of Mg, and the lowest levels (20.83 μg ...Daha fazlası

Eutrophication Status of the Berdan and Göksu River Basins in Turkey

İSMAİL AKÇAY | ÖZGÜR ÖZBAY | MEHMET TAHİR ALP

In this study, the eutrophication status of the Berdan and Göksu River Basins was determined by using recently obtained data between September 2021 and August 2022. Very high total phosphorus and trophic index (TRIX) values indicated that all stations visited in the Berdan, and Göksu River Basins were characterized as eutrophic (bad). The correlations between TRIX and eutrophication-related parameters showed strong and positive relations between TRIX and concentrations of Chlorophyll-a and total phosphorus strongly suggesting that the increase in total phosphorus concentrations highly enhanced ...Daha fazlası
