Abstract
With the development of offshore and Pelagic Fisheries, the continuous expansion of fishing routes, the corresponding ship tonnages are increasing, and the air pollution of vessels is becoming more and more serious. An offshore fishery research vessel was selected as the object, the emission factors were obtained according to its basic data, the method based on fuel consumption was adopted to calculate the air pollutants emission (NOx, HC, CO and PM10) and the emission inventory was established. The inventory provides data for the establishment of the emission inventory of offshore pelagic fishery in the future, and has positive significance for the establishment of green fishing in the future.
Highlights
With the vigorous development of fishing equipment and technology, the promotion of economic benefits, offshore and pelagic fisheries have rapidly developed in China
Particulate matter is generally formed by the condensation of hundreds volatile and semi volatile substances on the carbon core[3], which can lead to body inflammation, asthma and cardiopulmonary disease[4,5]
Marine vessels are the main source of nitrogen oxides (NOx) emissions in the world[7]
Summary
With the vigorous development of fishing equipment and technology, the promotion of economic benefits, offshore and pelagic fisheries have rapidly developed in China. Marine vessels are the main source of nitrogen oxides (NOx) emissions in the world[7]. T S Jin et al investigated the overall situation of transport ships in Tianjin port, and reasonably selected emission factors according to their emission control level[9]; based on the method of fuel consumption, the NOx, HC, CO and PM10 emissions from transport ships in Tianjin port in 2006 were calculated, and the emission inventory of air pollutants from transport ships in Tianjin Port was established. The emission factors of the research vessel are selected according to the investigation situation. Based on the method of fuel consumption, the air pollutant emissions (NOx, HC, CO and PM10) of the research vessel in 2020 are calculated, and the emission inventory is established. The inventory provides data for the establishment of the emission inventory of offshore and pelagic fishery in the future, and has positive significance for the establishment of green fishing
