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）要求建筑材料和工程的设计方式，应确保在整个生命周期内，其对环境的影响不会过高。本工作的目的是使用地下水风险评估（GRA）评估灰泥和砂浆的雨水径流的环境风险。源项浸出液基于用灰泥和砂浆涂覆的垂直测试板（VTP）的无机物质浸出预测模型获得的结果。在评估过程中，确定了在暴雨事件期间，由于浓度极高，灰泥和砂浆浸出的钒、铬、铅和锌是相关物质，这可能导致地下水化学状态发生重大变化。评估表明，铬是唯一浸出物质，使所选技术建筑应用特定场景下的一种材料的适用性失效。
