The serious fine particle (PM2.5) pollution in China causes millions of premature deaths. Driven by swift economic growth and stringent control policies, air pollutant emissions have changed significantly the last decade, but change source contribution PM2.5-related health impacts remains unclear. In this study, we develop a multi-pollutant emission inventory for 2005-2015, combine chemical transport modeling, ambient/household exposure evaluation impact assessment to quantify eight sectors...
Serious ambient PM2.5 and O3 pollution is one of the most important environmental challenges China, necessitating an urgent cost-effective cocontrol strategy. Herein, we introduced a novel integrated assessment system to optimize NOx volatile organic compound (VOC) control strategy for synergistic reduction pollution. Focusing on Beijing–Tianjin–Hebei cities their surrounding regions, which are experiencing serious in found that emission (64–81%) essential attain air quality standard no...
Efficient prediction of the air quality response to emission changes is a prerequisite for an integrated assessment system in developing effective control policies. Yet, representing nonlinear controls with accuracy remains major barrier quality-related decision making. Here, we demonstrate novel method that combines deep learning approaches chemical indicators pollutant formation quickly estimate coefficients functions using ambient concentrations 18 simulated comprehensive atmospheric...
Abstract. Quantification of emission changes is a prerequisite for the assessment control effectiveness in improving air quality. However, traditional bottom-up method characterizing emissions requires detailed investigation data (e.g., activity and other parameters) that usually takes months to perform limits timely assessments. Here we propose novel address this issue by using response model provides real-time estimation based on quality observations combination with emission-concentration...
Abstract Since 2013, China has taken a series of actions to relieve serious PM 2.5 pollution. As result, the annual concentration decreased by more than 50% from 2013 2021. However, ozone pollution become pronounced, especially in North Plain. Here, we review impacts anthropogenic emissions, meteorology, and atmospheric processes on ambient loading components O 3 China. The reported influence interannual meteorological changes during 2013–2019 ranged 10%–20% 20%–40%, respectively. During...
A big gap exists between current air quality in China and the World Health Organization (WHO) global guidelines (AQG) released 2021. Previous studies on pollution control have focused emission reduction demand but ignored influence of transboundary pollution, which has been proven to a significant impact China. Here, we develop an emission-concentration response surface model coupled with quantify for achieve WHO AQG. cannot AQG by its own high both PM2.5 O3. Reducing will loosen NH3 VOCs...
Emissions of organic compounds have strong influences on the environment. Most previous emission inventories only cover emissions particulate carbon and nonmethane volatile (NMVOC) but neglect semivolatile intermediate (S/IVOC), which considerably contribute to aerosol (OA) burden. Herein, we developed a full-volatility inventory in China from 2005 2019 analyzed OA formation potential (OAFP) each volatility bin source using two-dimensional basis set (2D-VBS) box model. The low/extremely...
From 2013 to 2019, a series of air pollution control actions significantly reduced PM2.5 in China. Control included changes activity levels, structural adjustment (SA) policy, energy and material saving (EMS) end-of-pipe (EOP) several sources, which have not been systematically studied previous studies. Here, we integrate an emission inventory, chemical transport model, health impact assessment scenario analysis quantify the contribution each action across range major sources concentrations...
Abstract. Designing effective control policies requires efficient quantification of the nonlinear response air pollution to emissions. However, neither current observable indicators nor based on surface modeling (RSM) can fulfill this requirement. Therefore, study developed new RSM-based and applied them ambient fine-particle (PM2.5) ozone (O3) in China. The performance these predicting O3 PM2.5 chemistry was compared with that indicators. H2O2 × HCHO∕NO2 total ammonia ratio, which exhibited...
Organic aerosol (OA) is a key component of fine particulate matter (PM2.5) and affects the human health leads to climate change. With strict control measures for air pollutants during last decade, OA concentration in China declined slowly, while its sources remain unclear. In this study, we simulate primary (POA) secondary (SOA) concentrations from 2005 2019 with state-of-the-art quality model, Community Multiscale Air Quality (CMAQ, version 5.3.2) coupled Two-Dimensional Volatility Basis...
ABSTRACT China currently has the highest acid deposition globally, yet research on its status, impacts, causes and controls is lacking. Here, we compiled data calculated critical loads regarding deposition. The results showed that abatement measures in have achieved a sharp decline emissions of acidifying pollutants continuous recovery precipitation pH, despite drastic growth economy energy consumption. However, risk ecological acidification eutrophication no significant decrease. With...
In the pursuit of carbon neutrality, China's 2060 targets have been largely anchored in reducing greenhouse gas emissions, with less emphasis on consequential benefits for air quality and public health. This study pivots to this critical nexus, exploring how neutrality aligns World Health Organization's guidelines (WHO AQG) regarding fine particulate matter (PM
Based on PM2.5 monitoring data, meteorological observation and a CMAQ-ISAM air quality model, the spatio-temporal variation, conditions, regional transport characteristics of 108 pollution events in Beijing from 2018 to 2022 were analyzed. The results showed that frequency, mean concentration, peak concentration demonstrated significant decrease degree moderate heavy was significantly larger than light events.
