Kalite kontrolü için, standart prosedür, laboratuvar boşlukları olarak, algılama (LOD), kurtarma ve tekrarlanabilirlik sınırları 23 incelenmiştir. Birkaç böcek ilaçları, düşük konsantrasyon seviyelerinde boş örneklerde tespit edildi. LODs ortalama LODs silikon kauçuk, POCIS-A için 1.7 pg mutlak 1.6 sütun üzerine enjekte 8.0 pg mutlak 3. Bu gürültü oranına bir sinyal kriterlerini karşılayan kalibrasyon eğrisine en alçak noktası değeri olarak belirlendi pg POCIS-B, SDB-RPS disk ...

Pestisitler sürekli su ortamında tanıtıldı ve Sucul organizmalar 1 için risk teşkil edebilir. Sulu bir ortamda pestisit izlenmesi tipik olarak akış ya da epizodik girdiler (örneğin, çökeltme, kombine kanalizasyon taşmaları, kanalizasyon lagün salım) 2 dalgalanmalar kapmak örnekleme, ancak bu örnekleme tekniği tamamen konsantrasyonlarda zamansal farklılıkları hesaba gelmez kullanılarak yapılır 3. Böylece, izleme yöntemleri pestisitler ile ilgili çevresel risklerin daha iyi bir tahmini için geliştirilmiş olması gerekir. Pasif örnekleme minimum altyapı ve düşük kirletici konsantrasyonları 4,5 ile uzun bir süre boyunca sürekli olarak izlenmesine olanak verir. Pasif numune yeraltı 6 izleme, tatlı su 7-10, atıksu 11 ve deniz suları 12 için değerli bir araç olduğu gösterilmiştir. izleme amacıyla yanında <sup&gt; 13,14, pasif numune de hedef olmayan analizi 15, toksikoloji testleri 16,17 kullanılmaktadır, ve bir alternatif olarak sediment- ve 18 biyoizleme için. Pasif numune sudan sürekli kimyasallar birikir ve ağırlıklı ortalama (TWA) 14 konsantrasyonlar zamanı sağlar. Kirletici alımı pasif örnekleyici tasarım, örnekleyici malzeme, kirletici fizikokimyasal özellikleri ve çevresel koşullara (örneğin, su bağlıdır örnekleme hızı (R ve S) ve pasif örnekleyici-su dağılım katsayısı (K PW) bağlıdır türbülans, sıcaklık) 13,14,19,20. ayrıntılı video kalibre ve su pestisitlerin pasif numune nasıl uygulanacağına göstermeyi amaçlıyor. Özel hedefler i) pasif sampl beş farklı türleri kullanarak 124 farklı böcek ilacı için hazırlık, çıkarma ve enstrümantal analiz gerçekleştirmek için dahilsilikon kauçuk içeren, ERS polar organik kimyasal birleştirici örnekleyici (POCIS) -A, POCIS-B, uykuda solunum bozukluğu-RPS ve C 18 diski, ii) Bir laboratuar alımının etüd pestisit R, S ve K, PW değerlendirmek ve iii) ilgi ve nasıl kendi pasif örnekleyici için TWA konsantrasyonlarının hesaplamak için hedef bileşiğin uygun pasif örnekleyici seçmek için nasıl göstermek için. Referans standartları ve pasif örnekleyici cihazları Hedef bileşikler, 124 mirası ve herbisit, insektisit ve fungisit (Tablo 1) de dahil olmak üzere şu anda kullanılan böcek ilaçları dahildir. Iç standart karışım (karışım IS) fenoprop (2,4,5-TP), klotiyanidin-D 3, etion ve terbutilazin-D 5 dahil. Diğer kullanılan kimyasallar metanol (MeOH), asetonitril (ACN), aseton (ACE), diklorometan (DCM), sikloheksan (CH), etil asetat (EA) dahil, petrol veOnunla (PE), 2-propanol,% 25 amonyak çözeltisi, asetik asit (HAc) ve formik asit (FA). Beş farklı pasif örnekleme cihazlar, silikon kauçuk, POCIS-A ve POCIS-B, SDB-RPS ve C18 diski 1,21 da dahil olmak üzere karakterize edilmiştir. Tablo 1.

characterization and application of passive samplers for monitoring of pesticides in water

Beş farklı su pasif numune 124 mirası ölçümü ve mevcut kullanılan pestisitler için laboratuvar koşullarında kalibre edildi. Bu çalışma, pasif örnekleyici hazırlama, kalibrasyon, ekstraksiyon yöntemi ve enstrümantal analiz için bir protokol sağlar. Örnekleme oranları (R ve S) ve pasif örnekleyici-su bölünme katsayısı (K PW), silikon kauçuk, polar organik kimyasal birleştirici örnekleyici POCIS-A, POCIS-B, uykuda solunum bozukluğu-RPS ve C 18 disk için hesaplanmıştır. Seçilmiş bileşiklerin alımı fizikokimyasal özelliklerine bağlı, yani, silikon kauçuk POCIS-A ise POCIS-B ve SDB- (oktanol-su bölünme katsayısına (K OW)&gt; 5.3 log) daha fazla hidrofobik bileşikler için, daha iyi bir alımının gösterdi RPS diski hidrofilik bileşiklerin (K ow &lt;0.70 log) için daha uygun idi.

Beş farklı pasif örnekleyici teknikleri 124 mirasının alımı ve silikon kauçuk (Şekil 1) ve POCIS A, POCIS B, SDB-RPS ve C 18 diskte (Şekil 2) dahil olmak üzere mevcut kullanılan pestisitlerin için karşılaştırıldı. ekstraksiyon yöntemi ve enstrümantal analiz performansı optimize edildi. Laboratuar alım deneylerinin sonuçları PW değerleri farklı böcek ilacı (Şekil 3) için alım ...
