中文摘要 | 本研究評估水田殺螺劑三苯醋錫(fentin acetate ) 45% 可濕性粉劑和田埂用 殺草劑嘉磷塞(glyphosate) 41% 溶液對水蚤(Scapholeberis kingi Sars)繁殖的影響, 利用14天測試期間內母蚤的存活數和小蚤產生總數為觀測因子,估計其對水蚤 繁殖的無毒害濃度、最低影響濃度及慢毒性值。試驗結果顯示,三苯醋錫 45% 可濕性粉劑和嘉磷塞 41% 溶液對水蚤的48小時急毒性值分別為0.012 mg/l(95% 可信賴界限為0.0054 - 0.046 mg/l)及> 100 mg/l。三苯醋錫 45% 可濕性粉劑對水 蚤繁殖的無毒害濃度為< 0.00031 mg/l,遠低於田間最低推薦濃度;嘉磷塞41% 溶液對水蚤的慢毒性影響估計值為0.14 mg/l,建議環境中持續存在量應不超過此濃度。 |
英文摘要 | This study evaluated exactly how two pesticides (fentin acetate 45% WP nad glyphosate 41﹪ S), that are commonly used in the paddy fields of Taiwan , influence reproduction of the water flea (Scapholeberis kingi Sars). Both mortality and reproduction per adult female flea during 14 days of test periods were recorded. This study also determined no observed effect concentration (NOEC) , lowest observed effect concentration (LOEC) and chronic value (ChV) of pesticides to water flea. The 48 hours effective concentration of fentin acetate and glyphosate to water flea were 0.012 mg/1 (95% confidence limits were 0.0054-0.046 mg/1) and>100 mg/1, respectively. NOEC of fentin acetate to water flea was < 0.00031 mg/1, i.e significantly lower than the concentration applied to the paddy field. Moreover, NOEC and LOEC values were used to evaluate the chronic value of glyphosate 41% S for the water flea. Based on those results, we recommend a limit concentration (0.14 mg/1) as a threshold for environmental pollution. |
