The Impact of Haze on Healthcare Utilizations for Acute Respiratory Diseases: Evidence From Malaysia

open access: yesFrontiers in Ecology and Evolution, 2021
Haze imposes a substantial disease burden on the human population especially in the Southeast Asia region due to the high frequency of haze episodes. The reduction of air quality levels by haze has resulted in a substantial disease burden and an increase

Coracoid process transfer and distal clavicle resection for chronic acromioclavicular separation

open access: yesJSES International, 2023
Background: Dewar’s procedure for transferring the coracoid process with the short head of biceps and coracobrachialis was reported in 1965 for treatment of both acute and chronic acromioclavicular (AC) joint separation, but little contemporary ...

Dense-Haze: A Benchmark for Image Dehazing with Dense-Haze and Haze-Free Images [PDF]

open access: yes2019 IEEE International Conference on Image Processing (ICIP), 2019
Single image dehazing is an ill-posed problem that has recently drawn important attention. Despite the significant increase in interest shown for dehazing over the past few years, the validation of the dehazing methods remains largely unsatisfactory, due to the lack of pairs of real hazy and corresponding haze-free reference images.

Dust emission reduction enhanced gas-to-particle conversion of ammonia in the North China Plain

open access: yesNature Communications, 2022
Liu et al. found that the formation rate of particulate ammonium is slower in the atmosphere than that observed in the laboratory, while it is sped up due to an increase in aerosol acidity driven by an emission reduction of dust in North China Plain.

The contribution of industrial emissions to ozone pollution: identified using ozone formation path tracing approach

open access: yesnpj Climate and Atmospheric Science, 2023
Wintertime meteorological conditions are usually unfavorable for ozone (O3) formation due to weak solar irradiation and low temperature. Here, we observed a prominent wintertime O3 pollution event in Shijiazhuang (SJZ) during the Chinese New Year (CNY ...

Regime‐Dependence of Nocturnal Nitrate Formation via N2O5 Hydrolysis and Its Implication for Mitigating Nitrate Pollution

open access: yesGeophysical Research Letters, 2023
The heterogeneous hydrolysis of dinitrogen pentoxide (N2O5) is an important pathway in nitrate formation; however, its formation rate and relative contribution to total particulate nitrate (pNO3‐) are highly variable.

Spatiotemporal Analysis of Haze in Beijing Based on the Multi-Convolution Model

open access: yesAtmosphere, 2021
As a kind of air pollution, haze has complex temporal and spatial characteristics. From the perspective of time, haze has different causes and levels of pollution in different seasons.

Variations in Levels and Sources of Atmospheric VOCs during the Continuous Haze and Non-Haze Episodes in the Urban Area of Beijing: A Case Study in Spring of 2019

open access: yesAtmosphere, 2021
To better evaluate the variations in concentration characteristics and source contributions of atmospheric volatile organic compounds (VOCs) during continuous haze days and non-haze days, hourly observations of atmospheric VOCs were conducted using a ...

The impact of FDI on haze pollution: “Pollution paradise” or “pollution halo?”--Spatial analysis of PM2.5 concentration raster data in 283 cities

open access: yesFrontiers in Environmental Science, 2023
This paper constructs a spatial econometric model based on the environmental Kuznets curve to examine the effect of foreign direct investment (FDI) on urban haze pollution in Chinese cities.
