A requirement of the Construction Products Regulation (CPR) in the European Union states that construction materials and works must be designed in a way that throughout their entire life cycle, they have no exceedingly high impact on the environment. The objective of the current work was to evaluate the environmental risk of stormwater runoff from plasters and mortars using the Groundwater Risk Assessment (GRA). The source term eluates are based on the results obtained by a model for leaching prediction of inorganic substances for vertical test panels (VTPs) coated with plasters and mortars. During the evaluation, it was determined that vanadium, chromium, lead and zinc are relevant substances leached by plasters and mortars during rain events due to the high magnitude of concentrations, which can lead to a significant alteration in the chemical status of groundwater. The evaluation showed that chromium is the only leached substance that invalidates the applicability of one of the materials for a particular scenario of a selected technical construction application.

欧盟建筑产品法规 (CPR) 的一项要求指出，建筑材料和工程的设计方式必须确保在其整个生命周期内不会对环境产生极大的影响。当前工作的目标是使用地下水风险评估 (GRA) 评估来自石膏和砂浆的雨水径流的环境风险。源项洗脱液基于对涂有灰泥和砂浆的垂直试验板 (VTP) 的无机物质浸出预测模型获得的结果。在评估过程中，确定钒、铬、铅和锌是雨天期间石膏和砂浆浸出的相关物质，因为浓度很高，这会导致地下水的化学状态发生重大变化。评估表明，铬是唯一一种使一种材料在选定技术建筑应用的特定场景中的适用性无效的浸出物质。
