Abstract

The literature pertaining to the composition of produced waters and the fates and effects of these effluents in the marine environment has been reviewed. Discussions of lethal and sublethal effects have been complemented by considerations of data relating to crude oils, petroleum products, and individual constituents.

Two distinct strategies have been employed in attempts at discerning the ecological effects of produced water effluents: predictive and observational. The predictive approach involves determining the composition of the effluents and considering the toxicities of individual components in an attempt to deduce the overall toxicity of the effluent. The observational approach, although site-specific, provides direct and unequivocal information relating to ‘real-world’ effects.

By combining both the predictive approach and the observational approach, it can be concluded with a high degree of confidence that current practises for the disposal of produced waters are ecologically sound.

海上油气开采平台采出废水的生态效应
对有关生产水的组成以及这些废水在海洋环境中的命运和影响的文献进行了审查。在讨论致死和亚致死效应时,还考虑了与原油、石油产品和个别成分有关的数据。在试图辨别生产废水的生态影响时,采用了两种不同的策略:预测和观察。预测方法包括确定流出物的组成,并考虑个别成分的毒性,以试图推断流出物的总体毒性。观察方法虽然是针对特定地点的,但提供了与“现实世界”影响有关的直接和明确的信息。通过结合预测方法和观察方法,可以高度肯定地得出结论,目前处理产出水的做法在生态上是无害的。
