Study to simulate the dispersion of air pollution and propose solutions to mitigate pollution from the Cat Lo Vung Tau fishing port, Ba Ria - Vung Tau province

Abstract

The formation and development of seaports are closely associated with regional and local economic development. However, in addition to their positive socio economic impacts, seaport operations also generate negative effects on air quality and public health. Besides commercial seaport activities, fishing ports significantly contribute to air pollution in port areas. Therefore, it is necessary to establish an emission inventory from port related activities, simulate the dispersion of air pollutants from the Cat Lo Vung Tau fishing port to surrounding areas, and propose solutions for air quality management at the port. The emission inventory results indicate that annual emissions from fishing vessels and trucks include 2.463 tons of NOx, 1.520 tons of SO₂, 0.377 tons of CO, 0.251 tons of PM₂.₅, and 0.273 tons of PM₁₀. Emissions from fishing vessel activities are mainly concentrated within the port area. Air quality simulations using the TAPM–AERMOD modeling system show that air quality in the port area is not polluted and does not adversely affect surrounding areas. The study also proposes mitigation measures to prevent and minimize air pollution, thereby supporting the sustainable development of the Cat Lo Vung Tau fishing port in the future.
