Abstract

A nanomaterial life-cycle risk assessment (Nano LCRA) of a graphene-enabled textile used in the construction of heat and fire-resistant personal protective equipment (PPE) was conducted to develop, analyze, and prioritize potential occupational, health and environmental risks. The analysis identifies potential receptors and exposure pathways at each product life-cycle stage and makes a qualitative evaluation of the potential significance of each scenario. A literature review, quality evaluation, and database were developed as part of the LCRA to identify potential hazards associated with graphene-based materials (GBMs) throughout the product life-cycle. Generally, risks identified from graphene-enabled textiles were low. Of the developed exposure scenarios, occupational inhalation exposures during raw material and product manufacturing ranked highest. The analysis identifies the key potential human and environmental hazards and exposures of the products across the product life-cycle of graphene enabled textiles. Priority research gaps to reduce uncertainty include evaluating long-term, low dose graphene exposures typical of the workplace, as well as the potential release and hazard characterization of graphene-acrylic nanocomposites.

消防装备中石墨烯纺织品的生命周期风险评估。

对用于制造隔热和耐火个人防护设备（PPE）的石墨烯纺织品进行了纳米材料生命周期风险评估（Nano-LCRA），以开发、分析潜在的职业、健康和环境风险，并确定其优先级。该分析确定了每个产品生命周期阶段的潜在受体和暴露途径，并对每个场景的潜在意义进行了定性评估。作为LCRA的一部分，开发了文献综述、质量评估和数据库，以确定石墨烯基材料在整个产品生命周期中的潜在危害。一般来说，石墨烯纺织品的风险很低。在已制定的接触情景中，原材料和产品制造期间的职业性吸入接触排名最高。该分析确定了石墨烯纺织品整个产品生命周期中的主要潜在人类和环境危害以及产品暴露。减少不确定性的优先研究缺口包括评估工作场所典型的长期低剂量石墨烯暴露，以及石墨烯-丙烯酸纳米复合材料的潜在释放和危害表征。
