| 摘要: |
| 综合污水包括工业废水、生活污水和农业废水(含化肥、农药等)。据统计，每年排人渤海湾的工业废水达5.28亿吨，生活污水1.4亿吨，它们绝大部分经排污河汇流人海，造成了河口海域的污染。
鱼类等海洋生物具有敏锐的嗅觉和味觉，在体表上亦分布有许多化学感受器，能够感知许多低浓度的化学物质，并发生回避反应，这是海洋生物对水环境污染的一种保护性反应。我们利用梭鱼Mugil so-iuy、鲈鱼Lateolabrax japonicus、罗非鱼Tilapia mossambica和对虾Penaeus orientalis等几种河口生物对天津市南、北排污河综合污水及其主要有机污染物的回避反应进行了试验研究，探讨综合污水及其几种主要有毒组分对海洋生物的毒性效应，为海域环境管理提供科学依据。 |

| Abstract: |
| Avoidance reactions of Mugil so-iny, Lateolabrax japonicus,Tilapia mossambica and Penaeus Orientalis to sewage and some of its constituents. were investigated using channeled avoidance trough.
The results suggest that organism avoided markedly mixed sewage (industrial waste water and domestic sewage). Avoidance indexes of organisms to three organic pollutants were shown in table 1.
The results showed that avoidance indexes of estuarine organisms to three organic pollutants were significant. However, the avoidance reaction of the fish was more sensitive than that of the crustacean. |
