在两年内监测锌和镀锌钢的大气腐蚀过程（金属损失）和径流过程。金属样品暴露于热带潮湿的气候在两个环境（农村和城市）在梅西科湾（塔巴斯科，墨西哥）。降雨事件，作为促进剂的径流过程进行了登记和分析的离子组成，pH值和电导率。在每次暴雨事件后监测锌径流进程，从暴露的金属样品中收集径流溶液，以确定作为可溶性释放腐蚀产物的一部分的锌质量损失。锌的大气腐蚀与几个环境参数符合线性关系。还提出了在潮湿热带气候中检测到的锌大气腐蚀产物的示意图。
During two years atmospheric corrosion process (metal loss) and runoff progress of zinc and galvanized steel where monitored. Metal samples were exposed to tropical humid climate in two environments (rural and urban) in the Gulf of México (Tabasco, Mexico). The rain events, as promoters of runoff process were registered and analyzed for ionic composition, pH and conductivity. The zinc runoff progress was monitored after each pluvial event, collecting runoff solutions from the metal samples in exposure, in order to determine the zinc mass loss, as a part of soluble, released corrosion products. The atmospheric corrosion of zinc fits a linear equation that relates the zinc corrosion with several environmental parameters. A schematic representation of zinc atmospheric corrosion products detected in humid tropical climate is also presented.
