中文摘要 | 本研究利用鯉魚(Cyprinus carpio)及水蚤(Daphnia pulex)為指標生物,根據「農 委會83年10月修正公佈之農藥對水生物毒性分類及其審核管理規定」,評估本省水稻田常用之布芬淨(buprofezin)及其混合劑對水生生物的急毒性。六個供試 原體級藥劑對供試生物均屬劇毒性,故成品對水生生物的毒性應再評估;十個 商品級製劑中僅布芬淨40%水懸劑及布芬滅蝨25%可濕性粉劑對供試生物屬輕 毒性。其餘8種藥劑:布芬淨25%可濕性粉劑(兩家不同公司產品)、布芬第滅寧11.78%乳劑、布芬大利松5%粒劑及25%可濕性粉劑、布芬治蝨2.5%粉劑 及25%可濕性粉劑和布芬丁滅蝨2.5%粉劑對供試生物毒性較高,在水稻田中推 廣使用對水生生物具潛在危險性。根據藥劑在不同作用時間下對水蚤的毒性變化趨勢,推測含布芬淨之藥劑對水蚤的毒性作用與水蚤的蛻皮過程有密切關係。 |
英文摘要 | Buprofezin and its chemical mixtures are extensively used for pest comtrol in the rice fields of Taiwan. In this study, we evaluated the toxicity of these chemicals to the aquatic organism according to the criterion established by the Council of Agriculture of the Republic of China. Test chemicals consisted of ten commercial pesticides and technical active ingredients. The toxicities were assessed with Cyprinus carpio and Daphnia pulex. According to the test results, six technical chemicals were all highly toxic to the tested organisms; the aquatic toxicity of their commercial product had to be evaluated as well. Among the commercial pesticides, only buprofezin 40% SP and buprofezin +MIPC 25%WP exhibited a slight amount of toxicity to aquatic organisms, buprofezin 25%WP (from two manufacturers), buprofezin + BPMC 2.5% DP, buprofezin + diazinon 5% GR and 25%WP, buprofezin + deltamethrin 11.78% EC and buprofezin + MTMC 2.5% DP could pose a major threat to aquatic organisms in a rice field. In addition, the relationship between exposure time and chemical toxicity to water flea was also discussed. Based on the results presented herein, we can infer/conclude that the toxicity mechanisms of buprofezin and its chemical mixtures may be related to the molting processes of Daphnia. |
