With present-day scientific evidence challenging the efficiency of artificial aeration as an effective restoration method for eutrophicated lakes, our sociohistorical investigation traces the reasons for the persistent support for this method in Finland, where about one hundred lakes are subject to this treatment. Our study employed the concepts of technological path and aeration frame to analyze the extensive restoration and aeration history of the hypertrophic Tuusulanjärvi in southern Finland. Continuously aerated since 1972, it has the longest history of aeration in Finland. Qualitative analysis of documentary and archival sources revealed that the longstanding preference for aeration in the context of increasing scientific controversy was based on its functional versatility and seemingly unproblematic applicability in regard to shifting emphasis and goal setting of restoration. Additionally, the stability of the aeration frame has been supported by the practical and emotional attachment of local residents to lake restoration, particularly aeration, and finally the problems and contradicting interests related to alternative restoration methods.
鉴于当今科学证据对人工曝气作为富营养化湖泊有效修复方法的效率提出质疑，我们的社会历史调查追溯了芬兰持续支持该方法的原因，芬兰约有100个湖泊接受这种处理。我们的研究采用技术路径和曝气框架的概念，分析了芬兰南部富营养化的图苏兰耶尔维湖广泛的修复和曝气历史。自1972年以来一直持续曝气，它拥有芬兰最长的曝气历史。对文献和档案资料的定性分析表明，在科学争议不断增加的背景下，对曝气的长期偏好基于其功能的多功能性以及在修复重点和目标设定不断变化方面看似毫无问题的适用性。此外，曝气框架的稳定性得到了当地居民对湖泊修复，特别是曝气的实际和情感依恋的支持，以及与替代修复方法相关的问题和相互矛盾的利益的支持。
