高科技產業放流水中生物效應評估及鑑識(34)-氧化物、高濁度、高酸鹼物質鑑定評估程序
| 中文摘要 | 本研究確認含氧化物（次氯酸鈉、過氧化氫）對水蚤及羅漢魚之毒性高低依序為：次氯酸鈉＞過氧化氫；水蚤及羅漢魚的耐酸鹼範圍分別為pH 5.4~10.2及pH 4.2~10.8；二物種對二氧化矽及氟化鈣產生之濁度，皆具有極高的耐受性（＞18000 NTU）。 運用規劃之毒性確認試驗流程，鑑定評估高科技產業放流水中氧化物（次氯酸鈉、過氧化氫）、高濁度（二氧化矽、氟化鈣）及高酸鹼物質（氫氯酸、氫氧化鈉）污染物的毒性，有效確認次氯酸鈉、過氧化氫、二氧化矽、氟化鈣及氫氯酸、氫氧化鈉污染物之毒性，發現含有次氯酸鈉及氫氧化鈉毒物之水體，藉由曝氣方式，不需添加任何藥劑，即可達到去除效果，屬於綠色及環保之物化處理方式。整合3年成果之毒性鑑定評估程序，可有效確認竹科高科技廠水樣HSP1的毒性來自銅離子、水樣HSP2則來自銅離子及銀離子，表明其運用於水體毒性成因鑑定及評估的潛力。 初步成果證實毒性鑑定評估程序互補歐盟毒性效應導向分析方法，並結合102年建立之斑馬魚胚胎慢毒性檢測方法，可有效鑑定及評估水體中潛藏毒化物。 | ||

The evaluation and identification of biological effects in high-tech industry effluent (3/4) – oxida
| 英文摘要 | This study confirms that the toxicity order of oxidants (sodium hypochlorite, hydrogen peroxide) to D.magna and Pseudorasbora parva is sodium hypochlorite > hydrogen peroxide. It also reveals that the suitable pH range for D. magna and Pseudorasbora parva is 5.4-10.2 and 4.2-10.8, respectively. Both species are highly tolerant to the turbidity caused by silicon dioxide and calcium fluoride (＞18000 NTU). The proposed toxicity identification evaluation (TIE) procedure was effectively used to confirm the toxicity by oxidants, turbidity, highly acidic and alkaline pollutants in high-tech industry effluents. Toxic and artificial industry effluents prepared by adding oxidants (sodium hypochlorite, hydrogen peroxide), turbidity (silicon dioxide, calcium fluoride), acidic and alkaline pollutants (hydrochloric acid, sodium hydroxide) were subjected to relevant physico-chemical treatments first. The toxicants were correctly identified and confirmed thereafter. The presence of hydrochloric acid and sodium hydroxide in water was effectively removed by simple aeration without adding any agent, representing a green and environmentally friendly treatment. Integration of toxicity identification evaluation procedures from the last three year achievements can efficiently identify the toxicity cause in Hsinchu Science Park high-tech industry plant water sample is by copper ions in HSP1 sample and copper/silver ions in HSP2, demonstrating its potential use for toxicity identification and evaluation in water body. Our preliminary result demonstrates that TIE procedure complemented to toxicity effect directed analysis method and integrated with Zebra fish embryonic chronic toxicity testing method developed in 2013 can effectively identify and evaluate potential toxicants in water body. | ||
