Marine water pollution affects many recreational sites around the world. It has impacts not only on recreational activities but also on health risks for those who come into direct contact with the water. Few economic studies have explicitly considered the health risks of bathing in polluted marine waters and none have attempted to separate health benefits from other benefits of marine water quality improvements. This paper uses stated preference techniques to separately evaluate the multiple benefits of improving the quality of marine recreational waters at the Estoril Coast in Portugal. The results indicate that health risk reductions are only a small fraction of the total social benefits of water quality improvements.
海水污染影响着世界各地的许多休闲场所。它不仅对休闲活动有影响，而且对那些直接接触海水的人的健康风险也有影响。很少有经济研究明确考虑在受污染的海水中游泳的健康风险，也没有一项研究试图将健康益处与改善海水质量的其他益处区分开来。本文运用陈述偏好技术，分别评估了改善葡萄牙埃斯托里尔海岸海洋休闲水域质量的多重益处。结果表明，降低健康风险只是水质改善带来的总社会效益的一小部分。
