The effect of small and medium scale shipyard operations on environmental pollutions related with public complaints in shipbuilding industry estate was estimated. The PM-10 concentrations of all sampling sites except 1 sampling point inside a shipyard were lower than the ambient air quality standard. Shipyard operations play negligible roles on the PM-10 concentrations in surrounding areas. However, shipyard operations were thought to affect the TSP concentrations in some region confined by the distance from shipyards. Paint particles emitted as vapors and then deposited as aerosols could affect much far regions than typicalch far regions thans. The odor in the research areas was estimated to be affected by the operations of shipyards. The combined odor intensities measured by air dilution sensory test were higher than the emission standards of stacks or border line of factories. Even though concentrations of specific odor compounds such as ammonia and methylmercaptan were higher than the emission standards, alint all odor compounds among 17 specific odor compounds analyzed were lower than the emission standards and odorous threshold values. The noise intensity generated from shipyards depend on the kind of works done in shipyards. The noise pollution of confined areas apart from shipyards were affected by the operations of shipyards. However, the affected areas were confined to some close regions from shipyards due to the distance decaying properties of noise.
