越来越多地使用工程纳米材料与新的性能相对于他们的散装同行产生了需要定义他们的行为和对环境的影响。 纳米颗粒的高表面积与体积比导致环境介质中的高反应性和物理化学动态材料。在环境和生物系统中，可能发生许多转化，例如与生物大分子的反应、氧化还原反应、聚集和溶解。这些转化和其他转化将改变纳米材料的命运、运输和毒性。 这些转变的性质和程度必须先了解，然后才能在了解这些材料造成的环境风险方面取得重大进展。
Increasing use of engineered nanomaterials with novel properties relative to their bulk counterparts has generated a need to define their behaviors and impacts in the environment. The high surface area to volume ratio of nanoparticles results in highly reactive and physiochemically dynamic materials in environmental media. Many transformations, e.g. reactions with biomacromolecules, redox reactions, aggregation, and dissolution, may occur in both environmental and biological systems. These transformations and others will alter the fate, transport, and toxicity of nanomaterials. The nature and extent of these transformations must be understood before significant progress can be made toward understanding the environmental risks posed by these materials.
