Study on Air Pollutant Emission Inventory for Offshore Fishery Resources Survey

Abstract

With the promotion of reform in various fields and the release of vitality of fishery development, Chinese fishery has achieved sustained and rapid development. Today, China has become one of the largest fishing countries, with abundant offshore and pelagic fishing routes, and a large number of vessels. The result is more and more pollutants emitted by vessels, which seriously affects the air quality of the surrounding environment. In this paper, a survey of offshore fishery resources in the East China Sea in 2020 was selected as the research object. The emission factors were summarized combined with the existing research results. The operation status of the survey was divided, and the calculation flow chart of air pollutant emissions was established, finally the emission inventory was estimated. The sharing rate of main/auxiliary engine and different operation status was discussed. The research data is the basement for the green, energy-saving, low-carbon and sustainable development of fishery in the future.
