Составите 5 вопросов ! ENVIRONMENTAL HEALTH AND SAFETY Nanomaterials have unusual and useful properties. But their unique attributes make nanomaterials a double-edged sword: they can be tailored to yield special benefits but also can have unknown and possibly negative impacts, such as unexpected toxicological and environmental effects. The environmental, health, and safety implications of nanotechnology are of significant concern to and a topic of serious discussion by government agencies and commissions, nongovernmental organizations (NGOs), the research community, industry, insurers, the media, and the public. A host of meetings and published reports have addressed EHS issues relating to nanotechnology, some of which are discussed below. EHS research published to date has provided some data indicating the potential for risks to laboratory animals exposed to nanomaterials and has shown that much more work is needed to assess the potential risks involved. Since much of what is learned as a result of EHS research will have a direct impact on R&D and manufacturing personnel who are initially exposed to nanomaterials, occupational health and safety risks, specifically in a workplace setting, must be considered.
