The use of fuels with strong percentage of ethanol that is done in countries such as Brazil and Australia causes a more and more relevant presence of traces of ethanol in natural waters. The ethanol present in these fuels seems to contribute to increase, through various mechanisms, the concentration of hydrocarbons in the same waters and soil. The ethanol content in natural waters must therefore be monitored frequently. It was therefore proposed a very simple innovative method, based on a catalytic fuel cell with the alcohol dehydrogenase enzyme immobilized in the anodic compartment of the device. The analytical performances of this new device were then evaluated by checking traces of alcohol in different types of natural waters (rain, river, and groundwater), with a good degree of precision and with an acceptable level of accuracy.
在巴西和澳大利亚等国，使用乙醇含量较高的燃料导致越来越多的乙醇痕迹出现在天然水中。这些燃料中存在的乙醇似乎通过各种机制促进了相同水域和土壤中碳氢化合物浓度的增加。因此，必须经常监测天然水中的乙醇含量。因此，提出了一种非常简单的创新方法，该方法基于一种带有固定在设备阳极室中的醇脱氢酶的催化燃料电池。通过检查不同类型的天然水（雨水、河水和地下水）中的酒精痕迹，评估了该新设备的分析性能，具有良好的精密度和可接受的准确度。
