Atratonun Sulama Kanalı Suyu ve Toprak Örneklerinde Gaz Kromatografisi Kütle Spektrometresi ile Tayini

Öz

Benefits such as disease prevention, improved food quality and yield are attributed to pesticide usage but severe health effects that arise from their wrong usage and continual accumulation in the environment has called for constant monitoring. Hastalıkların önlenmesi, arttırılmış gıda kalitesi ve ürün verimi gibi faydalar, pestisit kullanımı ile ilişkilendirilmektedir, ancak bunların yanlış kullanımının ve çevrede birikimlerinin sonucunda ortaya çıkan ciddi sağlık etkileri sürekli olarak izlenmelerini gerektirmektedir. Bu çalışma, atratonun sulama kanalı suyu ve toprak örneklerinde gaz kromatografisi- kütle spektrometresi ile yüksek doğrulukta tayinini gerçekleştirmek için yürütülmüştür. Analit için tatmin edici analitik performans verileri elde edilmiştir. Optimum koşullar altında, sulama kanalı suyu ve toprak örneklerinde yapılan analizlerde analit tespit edilememiş ve bu nedenle doğrusal çalışma aralığında bulunan farklı derişimlerde analit standartı ilave edilmesi işlemi gerçekleştirilmiştir. Karmaşık toprak matriksindeki analitin tayininin doğruluğunu arttırabilmek için kalibrasyon çözeltileri ekstrakte edilmiş toprak örnekleri içerisinde hazırlanmıştır. Standart ilave edilmiş sulama kanalı suyu örnekleri için ultra saf suda hazırlanan kalibrasyon standartlarına göre hesaplanan geri kazanım yüzdesi %97-110 arasında değişmektedir. Etanol içerisinde hazırlanan kalibrasyon standartları kullanılarak standart ilave edilmiş toprak örnekleri için hesaplanan geri kazanım yüzdesi ise %90-104 aralığındadır.

Determination of Atraton in Irrigation Canal Water and Soil Samples by Gas Chromatography Mass Spectrometry

Abstract

Benefits such as disease prevention, improved food quality and yield are attributed to pesticide usage but severe health effects that arise from their wrong usage and continual accumulation in the environment has called for constant monitoring. This study was performed to determine atraton in irrigation canal water and soil samples by gas chromatography mass spectrometry with high accuracy. Satisfactory analytical figures of merit were obtained for the analyte. Under the optimum conditions, the analyte was not detected in the analysis of irrigation canal water and soil samples and was therefore spiked at different concentrations within the linear calibration range. In order to increase the accuracy of quantifying the analyte in the complex soil matrix, calibration standards were prepared in soil extracts. The percent recoveries calculated for spiked irrigation canal water samples by calibration standards prepared in ultrapure water ranged between 97 and 110%. The percent recoveries calculated for spiked soil samples using the calibration standards prepared n ethanol ranged between 90 and 104%.
