Abstract In order to refresh guidance on garden statuary maintenance conservation, 16 biocides available on the British and European markets were selected for testing in situ at 11 properties of the National Trust (NT) located in England and Wales. For the testing, a range of decorative items, statues and architectural features were chosen, made of various types of stone, including limestone, sandstone, marble, slate and granite, as well as cast concrete, terracotta and brick. Tests were preceded by evaluation of the local microclimate and visual examination of the condition of the objects, including assessment of the presence of any micro-organisms and salt efflorescence. The history of previous conservation works and their materials was also reviewed. Microbiological analysis was carried out in many cases, which identified various algae, lichens and mosses. The effectiveness of the biocides and any potential side effects were evaluated periodically for 24 months after application. Three of the most effective biocides were selected for further assessment. An adenosine triphosphate (ATP) luminometer was used to measure whether biological growth had recurred on the stone at 7 and 12 months after application. Observed side effects included an occasional brown discolouration of Carrara marble after application of three of the biocides tested. An important outcome of the project was not only to recommend which biocides to use where treatment was necessary but also to determine when their use would not be advisable.

国家信托基金会(英国)为雕像和砖石“消毒”选择杀菌剂的研究

摘要为了更新关于花园雕像维护的指南,选择了英国和欧洲市场上可用的16种杀菌剂,对位于英格兰和威尔士的国家信托(NT)的11个物业进行了现场测试。为了进行测试,选择了一系列装饰性物品,雕像和建筑特色,这些装饰性物品由各种类型的石材制成,包括石灰石,砂岩,大理石,板岩和花岗岩,以及浇铸混凝土,兵马俑和砖头。在进行测试之前,先评估当地的微气候并目测检查物体的状况,包括评估是否存在任何微生物和盐渍化。还回顾了以前的保护工作及其材料的历史。在许多情况下进行了微生物分析,发现了各种藻类,地衣和苔藓。施用后24个月内定期评估杀生物剂的有效性和任何潜在的副作用。选择了三个最有效的杀菌剂进行进一步评估。使用三磷酸腺苷(ATP)发光仪测量在施用后7个月和12个月时石头上是否恢复了生物生长。观察到的副作用包括在应用三种测试的杀生物剂后,卡拉拉大理石偶尔会发生棕色变色。该项目的重要成果不仅是建议在需要治疗的地方使用哪种杀菌剂,而且还确定什么时候不宜使用。选择了三个最有效的杀菌剂进行进一步评估。使用三磷酸腺苷(ATP)发光仪测量在施用后7个月和12个月时石头上是否恢复了生物生长。观察到的副作用包括在应用三种测试的杀生物剂后,卡拉拉大理石偶尔会发生棕色变色。该项目的重要成果不仅是建议在需要治疗的地方使用哪种杀菌剂,而且还确定什么时候不宜使用。选择了三个最有效的杀菌剂进行进一步评估。使用三磷酸腺苷(ATP)发光仪测量在施用后7个月和12个月时石头上是否恢复了生物生长。观察到的副作用包括在应用三种测试的杀生物剂后,卡拉拉大理石偶尔会发生棕色变色。该项目的重要成果不仅是建议在需要治疗的地方使用哪种杀菌剂,而且还确定什么时候不宜使用。观察到的副作用包括在应用三种测试的杀生物剂后,卡拉拉大理石偶尔会发生棕色变色。该项目的重要成果不仅是建议在需要治疗的地方使用哪种杀菌剂,而且还确定什么时候不宜使用。观察到的副作用包括在应用三种测试的杀生物剂后,卡拉拉大理石偶尔会发生棕色变色。该项目的重要成果不仅是建议在需要治疗的地方使用哪种杀菌剂,而且还确定什么时候不宜使用。
