Although the general characteristics of estuarine chemical behaviour can be deduced from distributional data, there is an urgent need for greater understanding of the mechanisms and kinetics of the processes involved to assist the development of precise geochemical cycling models and to allow accurate predictions of the consequences of waste disposal into estuaries and inland waters. Manganese is of particular importance in this respect because, as well as exhibiting pronounced reactivity within estuaries, the highly absorptive properties of particulate and colloidal manganese oxide phases may contribute significantly to the estuarine behaviour of many other trace metals5. We show here how measurements of the effects of suspended particles and salinity on the rate of precipitation of dissolved manganese can lead to an explanation of the temporal and geographical variability in the distribution of dissolved manganese in an estuarine system.
