Abstract

Face masks serve as protective measures against pathogens and environmental pollutants. However, microplastic and phthalate pollutants present in the structure of masks may enter the nasal passages, potentially leading to health issues. In this study, we quantified microplastics and phthalate acid esters in masks used by hospital employees in various departments and in the nasal lavage fluid of these personnel before and after mask use. There were 200 participants, and the number of used masks was 160. The results indicated that the highest levels of microplastics (861.21 MP/mask) and Σ phthalate acid esters (3578.99ng/mL) were found in used masks from the laboratory. The amount of microplastics and phthalate acid esters in both masks and nasal lavage samples in the hospital departments were ranked as Laboratory > Physiotherapy > Emergency > Endoscopy. In nasal lavage samples, the amounts of these two pollutants decreased after mask use compared to the no-mask condition. Among the target phthalate acid esters, DEHP was the most prevalent in all mask and nasal lavage samples. These findings can be used for health risk assessment purposes.

医院职工使用口罩后鼻灌洗液中微塑料和邻苯二甲酸酯的定量分析

口罩是防止病原体和环境污染物的保护措施。然而，口罩结构中的微塑料和邻苯二甲酸盐污染物可能进入鼻腔，可能导致健康问题。在这项研究中，我们量化了医院各部门员工使用的口罩以及这些人员使用口罩前后鼻灌洗液中的微塑料和邻苯二甲酸酯。共有200名参与者，使用的口罩数量为160个。结果显示，在实验室使用过的口罩中发现了最高水平的微塑料（861.21 MP/口罩）和Σ邻苯二甲酸酯（3578.99ng/mL）。医院科室口罩和鼻灌洗液样品中微塑料和邻苯二甲酸酯含量依次为实验室>；物理治疗>；急诊>；内窥镜检查。在洗鼻样本中，与不戴口罩的情况相比，戴口罩后这两种污染物的含量有所下降。在目标邻苯二甲酸酯中，DEHP在所有口罩和洗鼻液样本中最常见。这些发现可用于健康风险评估。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
