中文摘要:
      随着我国工业建设的飞跌发展,各种工业废水排入天然水体的数量,日益激增。由于大多数废水在排放前缺乏必要的净化处理,在排入江河后,改变了水的自然性质,造成了不同程度的污染。这些废水中常含有某些毒物,给人民健康和水产资源带来了严重的后果。 对于这些有毒的工业废水,目前主要采取回收利用与处理相结合的办法,降低其毒性至对水生生物无害的程度,再排入天然水体。
英文摘要:
      Tests have been made on the fingerlings of the Cyprinid, Hypophthalmiohthys molitric,to determine the acute toxicity of certain phenolic effluent. The 24-hr TLm. and 48-hr TLm.were found to be 7.75 mg/L and 6.10 mg/L respectively at 6-8℃, and from which a "harm-less concentration" of 1.13 mg/L was computed after the formula of Hart et al. Oxygen con-sumption of the fish remained practically the same in a medium of 3.52 mg/L as in the bl-ank test; marked increase occurred when the concentration of the test solution was raised to6.07 mg/L. On the other hand, concentration up to 1.58 mg/L was sufficient to clicit an avo-iding reaction on the part of the fish. Growth rate of another Cyprinid, Ctenopharyngodonidella, was adversely affected even at a concentration of 0.05 mg/L. In view of these find-ings the authors propose that in evaluating the disposal index of phenolic wastes routine bio-assay method alone seems inadequate and should be supplemented by more refined toxicolog-ical research methods.
