摘要：为了评估碱式硫酸镁水泥对环境的影响，采用生命周期评价（LCA）方法，定量分析了碱式硫酸镁水泥的3种原材料在15项中点类别（致癌物质、非致癌物质、可吸入无机物等）和4项终点类别（人类健康、生态系统质量、气候变化、资源消耗）上的影响，并对比分析了不同镁质水泥的环境影响。结果表明：碱式硫酸镁水泥在水生生态毒性上的影响值最高，在臭氧层破坏上的影响值最低；氧化镁在致癌物质、非致癌物质和水生生态毒性上的影响占比较大，均超过85.00%；七水硫酸镁在电离辐射上的影响占比（53.67%）较大；柠檬酸在土地占有上的影响占比（68.80%）较大；在4项终点类别上，氧化镁的环境影响最大，七水硫酸镁次之，柠檬酸最小；与活性氧化镁水泥、磷酸镁水泥、氯氧镁水泥相比，碱式硫酸镁水泥在9项中点类别（致癌物质、非致癌物质、可吸入无机物等）和2项终点类别（气候变化、资源消耗）上优势明显。 Abstract: In order to evaluate the impact of basic magnesium sulfate cement on the environment, life cycle assessment (LCA) method was used to quantitatively analyze the impact of three raw materials of basic magnesium sulfate cement on fifteen midpoint categories (carcinogens, non-carcinogens, inhalable inorganic substances, etc.) and four endpoint categories (human health, ecosystem quality, climate change, resource consumption). The environmental impact of different types of magnesia cement was discussed. The results show that basic magnesium sulfate cement has the highest impact value on aquatic ecotoxicity and the lowest impact value on ozone depletion. Magnesium oxide has a relatively large impact on carcinogens, non-carcinogens and aquatic ecotoxicity, with the impact ratio exceeding 85.00%. The influence of magnesium sulfate heptahydrate on ionizing radiation is relatively large, with the impact ratio of 53.67%. The influence of citric acid on land possession is relatively large, with the impact ratio of 68.80%. In the four endpoint categories, magnesium oxide has the largest environmental impact, followed by magnesium sulfate heptahydrate, and citric acid is the smallest. Compared with the active magnesium oxide cement, magnesium phosphate cement and magnesium oxychloride cement, the basic magnesium sulfate cement has obvious advantages in the nine midpoint categories (carcinogens, non-carcinogens, inhalable inorganic substances, etc.) and two endpoint categories (climate change and resource consumption).
