The combination of acid water from mines, industrial effluents and sea water plays a determining role in the evolutionary process of the chemical makeup of the water in the estuary of the Tinto and Odiel rivers. This estuary is in the southwest of the Iberian Peninsula and is one of the estuarine systems on the northwest coast of the Gulf of Cádiz. From the statistical treatment of data obtained by analyzing samples of water from this system, which is affected by industrial and mining pollution processes, we can see how the sampling points studied form two large groups depending on whether they receive tidal or fluvial influences. Fluvial input contributes acid water with high concentrations of heavy metal, whereas industrial effluents are responsible for the presence of phosphates, silica and other nutrients. The estuarine system of the Tinto and Odiel Rivers can be divided into three areas--the Tinto estuary, the Odiel estuary and the area of confluence--based on the physical--chemical characteristics of the water.
来自矿井的酸性水、工业废水和海水的混合，在廷托河和奥迪尔河河口的水体化学组成演变过程中起着决定性作用。该河口位于伊比利亚半岛西南部，是加的斯湾西北海岸的河口系统之一。通过对受工业和采矿污染影响的该系统水样分析所获得的数据进行统计处理，我们可以看到，根据采样点受潮汐或河流影响的不同，所研究的采样点形成了两大组。河流输入带来了重金属浓度高的酸性水，而工业废水则导致了磷酸盐、二氧化硅和其他营养物质的存在。根据水体的物理化学特征，廷托河和奥迪尔河的河口系统可分为三个区域——廷托河口、奥迪尔河口和汇流区域。
