Extensive and long-term applications have resulted in global distributions of plastic additives (PAs). To facilitate the understanding of human exposure to PAs, the present study investigated the abundances and profiles of a broad range of PAs on human hands via hand wipe sampling. Sixty out of 160 PAs were detected in >50% of hand wipes collected from 30 children and 45 adults, among which a number of organophosphate esters (OPEs) and synthetic antioxidants that have rarely or never been investigated in prior studies. The total masses of PAs ranged from 650 to 87 030 ng (median: 6110 ng) and 1230 to 19360 ng (median: 5600 ng) in adults’ and children’s hand wipes, respectively. By categories, phthalates (PAEs) represented the most abundant group of PAs, followed by non-PAE plasticizers, UV stabilizers, OPEs, antioxidants, and bisphenol analogues. Children exhibited greater PA levels per square centimeter of hand surface, indicating elevated exposure compared with adults. Strong correlations existed for many PAs between adults and children or within each subpopulation, indicating close connections between the two subpopulations in the exposure profiles. The great complexity of plastic additives on hands raises the need for future investigations on human exposure pathways and potential health risks from the “cocktail” effects.

手巾中塑料添加剂的高度复杂性

广泛和长期的应用导致了塑料添加剂 (PA) 的全球分布。为了便于了解人类对 PA 的暴露，本研究通过擦手采样调查了人类手上各种 PA 的丰度和分布。在从 30 名儿童和 45 名成人收集的超过 50% 的手巾中检测到 160 种 PA 中的 60 种，其中一些有机磷酸酯 (OPE) 和合成抗氧化剂在之前的研究中很少或从未被研究过。成人和儿童擦手纸中 PA 的总质量分别为 650 至 87 030 ng（中值：6110 ng）和 1230 至 19360 ng（中值：5600 ng）。按类别划分，邻苯二甲酸酯 (PAE) 是最丰富的 PA，其次是非 PAE 增塑剂、紫外线稳定剂、OPE、抗氧化剂、和双酚类似物。儿童每平方厘米手表面的 PA 水平更高，表明与成人相比暴露水平更高。成人和儿童之间或每个亚群内的许多 PA 存在强相关性，表明暴露概况中的两个亚群之间存在密切联系。塑料添加剂在手上非常复杂，因此需要对人类接触途径和“鸡尾酒”效应的潜在健康风险进行未来调查。
