Geostatistical models have been widely used in the exposure assessment of ambient air pollutants. However, few studies have focused on comparisons of modeling approaches and their prediction results. Here, we collected the NO and PM monitoring data from 55 sites in Shanghai from 2016 to 2019 and the geographic variables, such as road network, points of interest of emission locations, and satellite data were included.

Short-term prediction of urban air quality is critical to pollution management and public health. However, existing studies have failed to make full use of the spatiotemporal correlations or topological relationships among air quality monitoring networks (AQMN), and hence exhibit low precision in regional prediction tasks. With this consideration, we proposed a novel deep learning-based hybrid model of Res-GCN-BiLSTM combining the residual neural network (ResNet), graph convolutional network (GCN), and bidirectional long short-term memory (BiLSTM), for predicting short-term regional NO and O concentrations.

SUMMA canisters were used to collect the exhaust gas from eight coating manufacturers in East China. A total of 106 VOCs was determined by gas chromatography-mass spectrometry (GC-MS) method to identify the emission characteristics of volatile organic compounds (VOCs) and the contribution of VOCs emitted by various companies to ozone generation, and the source profiles of solvent-based and water-based coatings were established. The results show that the characteristic components of VOCs in the coating manufacturing industry are mainly aromatic hydrocarbons and oxygenated hydrocarbons.

In this study, long-term continuous monitoring of atmospheric new particle formation was conducted from 2015 to 2017 in the Shanghai suburbs using a scanning mobility particle sizer (SMPS). Combined with meteorological parameters, gaseous pollutants, and PM chemical composition data, the characterization of new particle formation was analyzed. The results of data analysis showed there were 172 new particle formation (NPF) days in the Shanghai suburbs, accounting for 18.

To investigate the pollution characteristics of volatile organic compounds (VOCs) in the vicinity of a petrochemical park, the composition and concentration of VOCs was successively monitored by application of a gas chromatography-flame ionization detector in the residential area surrounding a petrochemical park in Shanghai in October 2017. Moreover, the maximum incremental reactive method was employed to estimate the O-formation potential contributed by VOCs, and health risks were assessed. Results showed that during the observation period, TVOCs concentrations ranged from 16.

Online GC was adopted to monitor VOCs of high pollution process near a chemical industrial area in winter. PMF model was used to identify the major sources of VOCs and evaluate their contributions. The result showed that the main components during the period of observation were toluene, xylene, C3-C4 hydrocarbon and chloroform, etc.

Objective: This study aimed to systematically assess the relevant risk factors of positive lateral margin (LM) after en bloc resection of early gastric adenocarcinoma.

Methods: A total of 242 patients who had undergone endoscopic submucosal dissection (ESD) due to early gastric lesions from January 2009 to March 2015 were included in the study. Clinicopathological features of the lesions and the risk factors related to positive LM were analyzed.

Analyses of diurnal patterns of PM10 in the downtown of Pudong, Shanghai have been performed in this study at different daily ozone maximum concentrations (O(3,max)) from May to October, 2010. In order to evaluate secondary aerosol formation at different ozone levels, CO was used as a tracer for primary aerosol, and 0(3, max) was used as an index for photochemical activity. Results show that along with increasing of O3 concentration, the concentration of primary and secondary aerosol was increased respectively from 0.

We developed an air pollutant emission inventory for marine vessels in the Shanghai Port in 2003. We estimated emissions under cruising and maneuvering conditions based on two categories of vessels: (1) vessels in the Outer Port, which enter the area following notification of the Shanghai Maritime Safety Administration, a division of the Ministry of Communications of P.R.

Article Synopsis
  • - The study aimed to analyze how ambient air pollution impacts human health and the disability-adjusted life years (DALYs) lost in Shanghai.
  • - Using epidemiology-based methods, researchers found that in 2000, air pollution in Shanghai resulted in a loss of 103,064 DALYs, primarily due to premature deaths and chronic bronchitis.
  • - The findings highlight that high levels of air pollution negatively affect public health, reinforcing the need for stricter pollution control measures in Shanghai.

Objective: To obtain the exposure-response functions that could be used in health-based risk assessment of particulate air pollution in China.

Methods: Meta analysis was conducted on the literatures on air particulate matter and its adverse health outcomes in China and worldwide.

Results: For each health outcome from morbidity to mortality changes, the relative risks were estimated when the concentration of air particulate matter increased to some certain units.
