Abstract: Fugacity concept is convenient in environmental chemical equilibrium. Mathematical model for simulation of chemical movement in the estuary consists of 3 compartments which are water, sediment, and seagrass. The influence factors at site location such as area, depth, volume, mass of water, mass of sediment, mass of seagrass, and current water flow were identified. The current water flow at Pulai River Estuary was measured in order to identify the allowable distance from mouth of Pulai River to Pulaiseagrass bed. The average wind speed can be found from World Weather and Climate information, 2015. The estimation method is practically used for getting the approximate estimation of concentration in each medium. The ratio of the concentration in each medium is called ‘concentration factor’. The ratio between seawater and sediment is 1: 1.439 x 10-3 ; ratio between sediment and seagrass is1: 4.25 x 10-9 ; and the ratio between seawater and seagrass is 1: 6.11x 10-12 C3. Thus, quantitative water, sediment and seagrass fugacity/ aquivalence mass balance model was developed for Pulai River Estuary is relevant.
