Distribution and Elimination of¹⁴C-Ethion Insecticide in Chamomile Flowers and Oil

Foliar Application of Calcium Chloride to Decrease Ethion Residues in the Oil of Chamomile Flowers and Soybean Seeds

“…The percent removal due to foliar applications of CaCl 2 after 30 days of the last application increased from 34% to 36%. Distribution and elimination of 14 C-ethion insecticide in chamomile flowers and oil was investigated (12) . Ethion residues were decreased by sun drying of chamomile flowers .The percentage of removal was 18-47% (12) .…”

“…14 C-Ethion had specific activity (7.4MBq/g), the radiometric purity was greater than 98% (Fig. 1 The non-labeled insecticide and some of its degradation products have been prepared in our laboratory (12) for identification purposes such as Ethion monooxon (II), Ethion dioxon (III), O,O-diethyl phosphorothioate (IV) and Oethyl phosphorothioate (V). The structures of these compounds were shown in Fig.…”
