In order to study the wall corrosion processes induced by visitors in the Altamira Cave (northern Spain), a multidisciplinary study was conducted in the cave. For a period of 1 year, a microclimate monitoring system, measuring the temperature, relative humidity, CO2 and 222Rn concentrations was operated. Host rock samples were collected as well as indoor and outdoor atmospheric particulate matter. These data are used for a quantitative assessment of the wall corrosion processes. The presence of visitors was found to enhance the corrosion processes up to 78 times in comparison with the natural processes. Outdoor air pollution did not have a significant affect.
为了研究西班牙北部阿尔塔米拉洞穴中游客引起的洞壁腐蚀过程，在该洞穴开展了一项多学科研究。在一年的时间里，运行了一个测量温度、相对湿度、二氧化碳和氡-222浓度的微气候监测系统。采集了母岩样本以及室内和室外大气颗粒物。这些数据用于对洞壁腐蚀过程进行定量评估。结果发现，与自然过程相比，游客的存在使腐蚀过程增强了78倍。室外空气污染没有显著影响。
