Abstract

In this study, it was aimed to determine the regional and temporal variations of organochlorine pesticide (OCP) concentrations in air and pollen samples in urban and semi-urban areas and the distribution between air/pollen. A total of 10 OCP (∑10OCP) concentrations in air and pollen samples during the sampling period were determined as 318.2±73.7 pg/m3 and 21.7±5.1 ng/g for the urban sampling point and 390.1±103.5 pg/m3 and 20.0±3.3 ng/g for the semi-urban point, respectively. In addition, it was determined that α-HCH and endosulfanß compounds were the most dominant OCP compounds in both pollen and air samples. High OCP concentrations were measured at both sampling points, usually during the summer months. Pollen/air partition coefficient (𝐾𝑃𝐴) was calculated to determine OCP exchange between air and pollen. According to the results obtained, it has been determined that there are generally OCP transitions from pollen to ambient air at both urban and semi-urban sampling points.

Özet

Bu çalışmada, kentsel ve yarı kentsel bölgelerdeki hava ve polen örneklerinde organoklorlu pestisit (OCP) konsantrasyonlarının bölgesel ve zamansal değişimleri ile hava/polen arasındaki dağılımların belirlenmesi amaçlanmıştır. Örnekleme periyodu boyunca hava ve polen örneklerindeki toplam 10 OCP (∑10OCP) konsantrasyonları kentsel örnekleme noktası için sırasıyla 318.2±73.7 pg/m3 v 21.7±5.1 ng/g, yarı-kentsel örnekleme noktası için ise sırasıyla 390.1±103.5 pg/m3 ve 20.0±3.3 ng/g olarak belirlenmiştir. Ayrıca α-HCH ve endosülfan-ß bileşiklerinin hem polen hem de hava örneklerinde en baskın OCP bileşikleri olduğu belirlenmiştir. Her iki örnekleme noktasında genellikle yaz aylarında yüksek OCP konsantrasyonları ölçülmüştür. Hava ve polen arasındaki OCP geçişlerinin belirlenmesi için polen/hava dağılım katsayısı (𝐾𝑃𝐴) hesaplanmıştır. Elde edilen sonuçlara göre, hem kentsel hem de yarı-kentsel örnekleme noktasında genellikle polenden dış ortam havasına OCP geçişlerinin olduğu belirlenmiştir.
