小议纳米材料的安全性评价问题

随着时间的推移，纳米科学和纳米技术的发展也在不断变化着，在其从被提出到现在的五十多年里，已经呈现出一个很好的应用前景。目前，人造纳米颗粒和纳米材料已经被应用于医药工业、染料、涂料、食品、化妆品和环境污染治理等行业中。然而，高科技是一把“双刃剑”，纳米材料在给人类带来巨大经济效益和科技革新的同时，其安全性评价也日益引起人们的重视。本文分析了纳米材料的发展史、性质、应用以及对畜牧兽医及人类的潜在威胁；综述了国内外对纳米材料安全性评价的态度；并重点提出了目前需要重点关注的纳米材料的毒性研究领域，同时呼吁大家高度重视纳米材料的安全性评估。

A Brief Analysis for Safety Evaluation of Nanomaterials

The development of nanoscience and technology has been changing with each passing day. During more than fifty years from they were put forward to now, its application has appeard a bright future. At present, artificial nanometer particles and nanometer materials have been used in medicine industry, dyes, paint, food, cosmetics and curbing environmental pollution. However, Technology is a double-edged sword. Indeed, the application of Nano- materials brings the huge social efficiency and the economic efficiency, meanwhile the safety evaluation of Nano- materials has attracted a great attention. This review discusses the science developmental histoI~, characters, appli- cation and potentiated risk to raise livestock and veterinarian and human of Nanomaterials . In addition, the atti- tudes towards safety evaluation of Nanomaterials and toxicology researches from home and aboard were reviewed. And we stress the toxicity research field of nanometer materials that we should especially keep a watchful eye on it, and call on the people to pay great attention to the safety evaluation of Nanomaterials.
