Phthalate acid esters (PAEs) are one of the most widely used plasticizers globally, extensively employed in various decoration materials. However, studies on the impact of these materials on indoor environmental PAE pollution and their effects on human health are limited. In this study, forty dust samples were collected from four types of stores specializing in decoration materials (flooring, furniture boards, wall coverings, and household articles). The levels, sources, exposure doses, and potential health risks of PAEs in dust from decoration material stores were assessed. The total concentrations of ΣPAE (the sum of nine PAEs) in dust from all decoration-material stores ranged from 46,100 ng/g to 695,000 ng/g, with a median concentration of 146,000 ng/g. DMP, DEP, DBP, and DEHP were identified as the predominant components. Among all stores, furniture board stores exhibited the highest ΣPAE (159,000 ng/g, median value), while flooring stores exhibited the lowest (95,300 ng/g). Principal component analysis (PCA) showed that decoration materials are important sources of PAEs in the indoor environment. The estimated daily intakes of PAEs through non-dietary dust ingestion and dermal-absorption pathways among staff in various decoration-material stores were 60.0 and 0.470 ng/kg-bw/day (flooring stores), 113 and 0.780 ng/kg-bw/day (furniture board stores), 102 and 0.510 ng/kg-bw/day (wall covering stores), and 114 and 0.710 ng/kg-bw/day (household article stores). Particularly, staff in wall-covering and furniture-board stores exhibited relatively higher exposure doses of DEHP. Risk assessment indicated that although certain PAEs posed potential health risks, the exposure levels for staff in decoration material stores were within acceptable limits. However, staff in wall covering stores exhibited relatively higher risks, necessitating targeted risk-management strategies. This study provides new insights into understanding the risk associated with PAEs in indoor environments.
邻苯二甲酸酯（PAEs）是全球使用最广泛的增塑剂之一，广泛应用于各种装饰材料中。然而，关于这些材料对室内环境PAE污染的影响及其对人体健康的影响的研究有限。在本研究中，从四类装饰材料专卖店（地板、家具板、墙面材料和家居用品）收集了40个灰尘样本。评估了装饰材料店灰尘中PAEs的含量、来源、暴露剂量和潜在健康风险。所有装饰材料店灰尘中ΣPAE（9种PAEs的总和）的总浓度范围为46100 ng/g至695000 ng/g，中位数浓度为146000 ng/g。DMP、DEP、DBP和DEHP被确定为主要成分。在所有店铺中，家具板店的ΣPAE最高（159000 ng/g，中位数），而地板店的ΣPAE最低（95300 ng/g）。主成分分析（PCA）表明，装饰材料是室内环境中PAEs的重要来源。通过非饮食性灰尘摄入和皮肤吸收途径，各类装饰材料店工作人员PAEs的估计每日摄入量分别为60.0和0.470 ng/kg体重/天（地板店）、113和0.780 ng/kg体重/天（家具板店）、102和0.510 ng/kg体重/天（墙面材料店）以及114和0.710 ng/kg体重/天（家居用品店）。特别是，墙面材料店和家具板店的工作人员DEHP暴露剂量相对较高。风险评估表明，虽然某些PAEs存在潜在健康风险，但装饰材料店工作人员的暴露水平在可接受范围内。然而，墙面材料店的工作人员风险相对较高，需要有针对性的风险管理策略。本研究为理解室内环境中PAEs相关风险提供了新的见解。
