Based on the sensitivity analysis conducted during the modeling of hazardous chemicals in coastal environments, of influential factors and key processes were ranked based on chemical type, model type, and state variables. Advection and diffusion were found to have significant influences on the dissolved chemicals. For chemicals in particulate organic matter, the most influential factors has the following order: the partition coefficient of particulate organic carbon, adsorption rate, and settling velocity. It is also necessary to conduct a sensitivity analysis of the desorption rate in future studies. For chemicals in phytoplankton, the bioconcentration factor was the most critical parameter, and future studies should include a sensitivity analysis of the excretion rate. For polycyclic aromatic hydrocarbons (PAHs), both the photolysis rate constant and dissipation rate were identified as key influencing factors.
