Nanomaterials for environmental remediation: investigating the role of nanoinformatics in support of environmental, health, and safety oversight of nanotechnologies at the local level.

摘要

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.
