为了对建筑室内装修和使用过程产生的大量有害物质对人体健康构成的威胁进行合理的量化评价,基于生命周期清单分析(life cycle inventory,LCI)方法和社会支付意愿(willingness-to-pay,WTP)的货币化评价方法,结合病理学和环境卫生学的成果,建立了建筑装修过程与健康损害指标之间的量化模型,实现了建筑装修过程的量化评价。在案例评价涉及到的建筑装修材料中,硝基涂料中大量含有的二甲苯的社会支付意愿达到162.54元/a,其对人体健康的损害最为显著。案例结果证明:本评价体系能够有效地识别装修过程中的主要健康损害源,并用货币化的方法进行表征,对于完善建筑工程环境影响评价方法体系、实现建筑工程健康损害的事前预测与控制具有重要的理论价值和实际意义。
In order to rationally evaluate the threat posed to human health caused by the large amount of harmful substances generated during the interior decoration and use of buildings, based on life cycle inventory (LCI) method and willingness-to-pay (WTP) ), And combined with the results of pathology and environmental hygiene, a quantitative model between the building decoration process and health damage index was established, and the quantitative evaluation of the building decoration process was realized. Among the building decoration materials involved in the case evaluation, the xylene content contained in the nitro-coatings is expected to reach 162.54 yuan / a, which is the most significant damage to human health. The results of the case show that this evaluation system can effectively identify the main sources of health damage during the decoration process and use the method of monetization to characterize it, which is very important for improving the environmental impact assessment method system for construction projects and for ex ante prediction and control of the health damage of construction projects The theoretical value and practical significance.
