对加热废水影响海洋和河口环境的方式进行了非常简短的回顾。描述了苏格兰艾尔郡亨特斯顿发电站的一些影响。该站以约 91000 立方米/小时的速率排放冷却海水，温度比环境温度高出约 10°C。在发电站投入运营之前和之后对邻近沙滩进行了数年的长期生态调查表明，最常见的生物体——双壳类Tellina tenuis——的密度变化并不是由热效应造成的。相比之下，Tellina 年轻阶段的生长速度似乎有所增加。亨斯顿的潮间带沙穴端脚类 Urothoë brevicornis 的繁殖和生长情况与 3 公里外米尔波特的对照种群进行了比较。与米尔波特动物相比，亨斯顿片脚类动物的繁殖季节更早，生长期更长。建议在公海情况下，在温带水域，目前的电站废水影响相对较小。然而，不应认为未来增加的废热处理不会对环境产生更严重的影响。
A very brief review is given of the way in which heated effluents can affect marine and estuarine environments. Some of the effects of the Hunterston Generating Station, Ayrshire, Scotland are described. This station discharges cooling seawater at about 10ºC above ambient at a rate of about 91000 m3/h. A prolonged ecological survey of the adjacent sandy beach for several years before and after the power station came into operation suggests that changes in the densities of the commonest organism, the bivalve Tellina tenuis, are not attributable to thermal effects. By contrast, the growth rates of young stages of Tellina appear to have increased. Breeding and growth at Hunterston of the intertidal sand-burrowing amphipod Urothoë brevicornis has been compared with a control population 3 km away, at Millport. Hunterston amphipods show an earlier breeding season and a more prolonged growth period compared with Millport animals. It is suggested that in open sea situations, in temperate waters, present power station effluents have relatively small effects. However, it should not be assumed that the increasing future disposals of waste heat will not have more drastic effects on the environment.
