摘　　要：分析2023年沈阳市工业企业燃料消耗、废气和主要污染物排放情况,并与环境空气质量进行相关性分析,讨论污染防治措施及环境空气提高措施的实施效果。结果表明,2023年,工业废气主要污染物为二氧化硫、氮氧化物、颗粒物和挥发性有机物,排放量分别为6,401.13吨、14,824.19吨、2,612.86吨、11,063.72吨。颗粒物、二氧化硫、氮氧化物主要排放行业为电力热力生产和供应业和非金属矿物制品业,挥发性有机物主要排放行业为医药制造业、汽车制造业。环境空气中二氧化硫浓度与二氧化硫排放量呈显著的正相关,可吸入颗粒物浓度与颗粒物排放量呈显著正相关,即随着污染排放量的减少而降低,且下降趋势明显,表明沈阳市大气污染防治及环境空气质量提高措施效果显著。The analysis of fuel consumption,exhaust gas,and major pollutant emissions from industrial enterprises in Shenyang in 2023,as well as the correlation analysis with ambient air quality,discusses the implementation effects of pollution prevention measures and ambient air improvement measures.The results show that in 2023,the main pollutants in industrial exhaust gas are sulfur dioxide,nitrogen oxides,particulate matter,and volatile organic compounds,with emissions of 6,401.13 tons,14,824.19 tons,2,612.86 tons,and 11,063.72 tons,respectively.The main emission industries for particulate matter,sulfur dioxide,and nitrogen oxides are the power and heat production and supply industry and the non-metallic mineral product industry,while the main emission industry for volatile organic compounds is the pharmaceutical manufacturing and automobile manufacturing industries.There is a significant positive correlation between sulfur dioxide concentration in ambient air and sulfur dioxide emissions,and a significant positive correlation between inhalable particulate matter concentration and particulate matter emissions,indicating that as pollution emissions decrease,so do the concentrations,and the downward trend is obvious.This suggests that the measures taken by Shenyang for air pollution prevention and ambient air quality improvement have achieved remarkable results.
