Aerial applications of pesticides  create a high off-target drift potential, which  results in unreliable effectiveness and could cause  contamination over large areas. Fenthion pesticide  (Queletox) was aerially applied in 2004 in Sebalola,  Botswana. As part of an Environmental Impact  Assessment of this operation, pre-spray soil  samples and post-spray soil samples were collected,  air-dried, bagged, transported to the UK and kept  deep frozen. Initial analysis of the samples as part  of the EIA study showed three post-spray samples  that had considerable amounts of the fenthion  pesticide. The aim of this study was to examine the  decay rates of fenthion using these samples. Lab  results showed that the resultant half-life of the  samples was 47 days. The concentrations of fenthion  residues after 64 days (0.26 mg\/kg-sample 1; 0.13  mg\/kg-sample 2; 0.04 mg\/kg-sample 3)were mainly  above approved maximum residue levels of fenthion in  animal products (0.05 mg\/kg, England and Wales).  This indicates a high tendency of fenthion to  persist in the soil medium.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838382777\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838382777","offer_id":39499055628381,"sku":"9783838382777","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1633a595-d675-4502-a082-08065ba6bc9f.jpg?v=1759211109","url":"https:\/\/shop.autorenwelt.de\/products\/decay-rates-of-fenthion-and-its-derivatives-in-soil-samples-von-enoch-adranyi","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
