Abstract

Colloids are abundant in all natural aquatic environments. The size of colloids ranges between 1 and 1,000 nm, at least in one dimension. They can consist of inorganic material (e. g. clay, carbonates, silicates), organic material (e. g. soot or high-molecular-mass organic carbon), and "bio-colloids" (e. g. bacteria, viruses, spores, algae). Colloids may influence the transport and fate of contaminants, especially trace elements and hydrophobic organic substances. They may also cause a pore space reduction. In particular, drinking water quality can be adversely affected by the transport and relocation of "bio-colloids"; however, the behaviour of colloids is not fully understood. The aim of this paper is to contribute to the understanding of the physical properties of colloids, their occurrence in natural aquatic systems, and their relevance.
