The chemical and physical characteristics of the particles of the near-surface waters of polluted, hypereutrophic, Onondaga Lake, NY, were observed by individual particle analysis techniques for the spring to fall interval of 1987. Strong temporal variations were documented for the projected particle area per unit volume (PAV), and the relative contribution that six chemical groupings of particles made to the overall assemblage of particles. These dynamics were regulated largely by (1) the composition and level of phytoplankton growth, (2) tributary loading of particles, particularly after runoff events, and (3) the precipitation of calcium carbonate. Approximately 85% of the PAV was associated with in-lake processes and {approximately} 15% was derived from tributary transport. Approximately 25% of the internally produced PAV was related to calcium carbonate precipitation; the remainder was associated with biological production. A once in 7-year runoff event caused a 5-fold increase in the concentration of suspended particles. Much of the increase was due to calcium carbonate precipitation that coated various nuclei particles.
