520 |a"Ultra-small particles in aquatic ecosystems are responsible for much of the transport and transformations of contaminants. These colloidal particles (0.001 to 1.0 um least diameter) are physically unstable, by virtue of their being ultra-small, thus causing electrical phenomena to dominate their aggregation/disaggregation behaviour. They tend to aggregate spontaneously when perturbed by physico-chemical changes in nature, thus altering their own settling properties and chemical activities. It is generally accepted that ultra-small particles must be characterized better than they have been, for an improved understanding of their important roles in aquatic ecosystems. The state-of- the-art technology for characterizing these particles has just been established, much of it by NWRl. This article reviews the new technology, and its "tunable" nature for use in a great variety of water types"--Abstract.
