渤海湾如同其他许多海域一样,也经受铅、汞、铬、镍、镉等重金属污染。一些研究表明,相应耐重金属菌数量等指数的变化可反映某一环境污染状况,它将为监测、评价和防治海洋污染提供依据,故了解本湾耐重金属菌等数量变动规律很有必要。 1979年,我们对渤海湾耐重金属菌等数量分布作了两航次调查,本文就所得资料作一分析。
Like many other seas, the Bohai Bay is also subject to heavy metal pollution such as lead, mercury, chromium, nickel and cadmium. Some studies show that the change of the index of the corresponding heavy metal-resistant bacteria can reflect a certain environmental pollution situation. It will provide the basis for monitoring, evaluating and preventing marine pollution. Therefore, it is necessary to know the quantitative changes of heavy metal-resistant bacteria in this Bay. In 1979, we made two voyages surveys on the quantity distribution of heavy metal-tolerant bacteria in Bohai Bay. This paper analyzes the data obtained.
