Nanotechnology is the science and practice of manipulating matter at or near atomic scale to create new materials of unique and novel properties for specific applications. Nanomaterials, including engineered nanoparticles (ENPs), have been used successfully for remediation since they are superior in technical performance and cost-effectiveness than traditional remedial technologies. Evidence indicates, however, that exposure to nanomaterials may lead to significant safety and health impacts. To protect human health against undesired risks from nanomaterials requires that safe and sustainable development of nanotechnology is in tandem with the availability of relevant information. State agencies responsible for the environment, safety, and public health were surveyed to understand their current and future information needs and capabilities to regulate nanomaterials. Because significant data gaps still exist on the toxicity and ecological impacts of nanomaterials, precautionary measures should be taken. Research to develop techniques for exposure assessments, surveillance and monitoring, databases, and characteristics of workplaces where ENPs are used is encouraged.
纳米技术是在原子尺度或接近原子尺度上操纵物质,以创造具有独特新颖特性的新材料用于特定应用的科学与实践。纳米材料,包括工程纳米粒子(ENPs),因其在技术性能和成本效益方面优于传统修复技术,已成功用于修复。然而,有证据表明,接触纳米材料可能会对安全和健康产生重大影响。为保护人类健康免受纳米材料带来的不良风险,需要纳米技术的安全可持续发展与相关信息的可得性同步。对负责环境、安全和公共卫生的国家机构进行了调查,以了解它们当前和未来的信息需求以及监管纳米材料的能力。由于纳米材料的毒性和生态影响方面仍存在重大数据空白,应采取预防措施。鼓励开展研究,以开发用于接触评估、监测和监视、数据库以及使用ENPs的工作场所特征的技术。
