Objective: With the acceleration of industrialization, air pollution has become a global environmental issue, particularly in cold regions where unique climatic and geographical conditions give rise to distinctive types impacts. Considering economic evaluation damage is crucial for effective control policies, this study aims provide more precise assessment method through Improved Virtual Control Cost Method (IVCCM) optimize governance strategies regions. Method: This utilizes case major company producing methanol coal-based natural gas, emissions from boiler exhaust exceeded prescribed standards particulate matter, sulfur dioxide, nitrogen oxides during specific period. By employing segmented counting approach that accounts downtime, calculations were conducted actual periods excess emissions. Adjustments made calculation coefficients within accurately reflect ecological caused by pollution. Results: The IVCCM revealed total loss company’s excessive amounted USD 1.6844 million, significantly lower than original (USD 2.1885 million). Specifically, losses due 0.0032 0.3600 1.3212 respectively. Conclusions: enables prediction Compared traditional methods, it effectively reduces costs, mitigates disputes arising unclear parameter values facilitates development rational protection policies measures.

Particularly fine particulate matter (PM2.5) has become a significant public health concern in China due to its harmful effects on human health. This study aimed examine the trends all causes and cause specific morality burden attributable PM2.5 pollution China.We extracted data mortality exposure for period 1990-2019 from Global Burden of Disease 2019. The average annual percent change (AAPC) age-standardized rates (ASMR) years life lost (YLLs) were calculated using Joinpoint Regression Program. Using Pearson's correlation, we estimated association between trends, urban green space area, higher education proportions.During 1990-1999, there increases All (1.6%, 95% CI: 1.5% 1.8%), Diabetes mellitus (5.2%, 4.9% 5.5%), Encephalitis (3.1%, 2.6% 3.5%), Ischemic heart disease (3.3%, 3% 3.6%), Tracheal, bronchus lung cancer (5%, 4.7% 5.2%). In 2010-2019, still showed an increase rates, but at lower rate with AAPC 1.2% (95% 1% 1.4%). Tracheal smaller this period, 0.5% 0.3% 0.6%). terms YLLs, appear be similar.Our findings highlight increasing China, particularly diabetes mellitus, tracheal, bronchus, cancer.
