【摘要】 本文选择浙江省沿海典型油气码头、干散货码头、件杂货码头和集装箱专用码头作为监测点,在一个自然年中分别选取代表日进行空气质量监测。根据污染物浓度水平,结合气象条件参数和交通流量参数,对大气污染物进行影响因素分析。结果表明:码头空气质量优于当地整体情况;SO₂、NO₂、PM_2.5和PM₁₀浓度变化与气温、湿度、风速呈负相关关系,与气压呈正相关关系,CO浓度受气象条件影响较小;靠港船舶和码头内作业车辆尾气是码头空气污染物的重要来源。更多还原

【Abstract】 Four typical oil & gas terminal,dry bulk terminal,general cargo terminal,and container terminal in Zhejiang were selected as the air quality monitoring areas. The sampling was conducted during represent days in a natural year. The air pollutant levels were compared with the meteorological conditions and traffic flow parameters. The results suggested that the air quality in typical ports were better than the local situation. The relative analysis showed that the concentrations of SO₂、NO₂、PM_2.5 and PM₁₀ were negative with air temperature,humidity and wind speed,and positive with air pressure. No significant correlation was found between the concentrations of CO and meteorological factors. The exhaust gas from ships and vehicles was the important source of air pollutants.更多还原
