大型无脊椎动物的葡萄牙指数在葡萄牙的地表水研究中用作污染指数。其他污染源的结合可能会导致生态损失。生态完整性，有必要应用复杂的模型，并可能在社会科学中使用彻底的统计工具（SEM）。在本文中，将SEM用于环境研究。 Sabor为了理解哪些是其主要污染源，哪些污染物限制了每个盆地的应用模型。水质水平。
The Portuguese Index of Macroinvertebrates is used as a pollution index in the study of surface water in Portugal. From an environmental perspective, it is necessary to determine the pollution sources affecting surface water. Not only direct discharges of industrial and urban effluents are the cause; possibly the combination of other pollutions sources could result in ecological loss. To comprehend all the cause and effect relationships between pollution sources, water contamination and ecological integrity, it is necessary to apply complex models and possibly apply the use of thorough statistical tools. Structural Equation Modelling (SEM) has been used in the social sciences for a long time. Due to the present environmental concern and awareness of the phenomenon’s complexity, SEM was used for environmental studies. In this paper are present SEM-PLS models that are applied to collected data from two different river basins, that of the Ave and the Sabor, in order to understand which are their main pollution sources and which contaminants are restraining biodiversity. The applied models from each basin reproduced different realities, as expected, since the river Ave has has the notorious impact of industry, while the Sabor basin has a higher level of water quality.
