Abstract
The estuarine modifications of zinc during its transport through the tropical Cochin estuary was evaluated by speciation studies. The fractions of zinc reported include Chelex‐100 labile and organically bound metal in the aqueous phase and exchangeable and total metal in the particulate phase. The behaviour of each of the above fraction in relation to the environmental factors such as salinity, suspended solids load and DOC is presented. The behavioural profile indicates the removal of all the fractions in the saline region of this tropical estuary. The mass balance indicated accumulation of zinc in the estuarine regions.Keywords
