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.

对用于构建耐热和防火个人防护装备 (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、分析和优先考虑潜在的职业、健康和环境风险。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，以识别整个产品生命周期中与石墨烯基材料 (GBM) 相关的潜在危害。一般来说，石墨烯纺织品的风险较低。在已制定的暴露场景中，原材料和产品制造过程中的职业吸入暴露排名最高。该分析确定了石墨烯纺织品在整个产品生命周期中对人类和环境的主要潜在危害和暴露。减少不确定性的优先研究差距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特征。
