Abstract
The Yangtze River Delta (YRD), which is the most developed region in China, suffers from atmospheric polycyclic aromatic hydrocarbons (PAH) pollution. However, the long-term spatiotemporal variation of atmospheric PAHs and the lung cancer risk caused by PAH exposure in the YRD remain unclear. Herein, we simulated the daily atmospheric concentration of benzo[a]pyrene (BaP, the most carcinogenic PAH) from 2001 to 2016 using an atmospheric transport model. During this period, the atmospheric BaP concentration showed a general trend of first increasing and then decreasing (average BaP concentration = 0.50 ± 0.12 ng/m3) and was highest in 2005 (0.72 ng/m3). Moreover, the BaP concentration in Jiangsu and Shanghai was 5.17- and 4.98-fold higher than that in Zhejiang. BaP pollution was severe in Jiangsu during the winter. The average area proportion of BaP exceeding the national standard in winter in Jiangsu was 69.09%. The population-weighted incremental lifetime cancer risk from 2001 to 2016 ranged 6.67 × 10-6-1.50 × 10-5, and the excess lung cancer cases ranged 1054-2130. Compared with 2005, excess lung cancer cases in the YRD decreased by 49.49% in 2016. Reducing BaP pollution in winter in Jiangsu is crucial for reducing lung cancer risk in the YRD.

BIOMED RESEARCH INTERNATIONAL 2021; 2021:1978434. [PMID: 34337001 PMCID: PMC8314042 DOI: 10.1155/2021/1978434] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 07/05/2021] [Indexed: 01/06/2023]
Abstract
Lung cancer is one of the most serious leading cancers with high incidence globally. Identifying molecular markers is key for disease diagnosis and treatment. Coal dust might be important triggering factors in disease development. Here, we first performed RNA-seq-based screening in coal dust treated and nontreated RAW264.7 cell lines. PHLDB2 was found to be the top differentially expressed gene. By retrieving TCGA lung cancer dataset, we observed that PHLDB2 showed upregulations in males and smoker patients. Patients with lower PHLDB2 expression survived longer than those with higher expressions. Furthermore, PHLDB2 was negatively correlated with EMT makers, and a total of 2.74% mutation rate were observed in 1,059 patients. This finding highlights the critical role of PHLDB2 in lung cancer development. PHLDB2 might be a molecular maker for disease diagnosis or treatment.

Abstract
This article reviews evidence for the public health impacts of coal across the extraction, processing, use, and waste disposal continuum. Surface coal mining and processing impose public health risks on residential communities through air and water pollution. Burning coal in power plants emits more nitrogen oxides, sulfur dioxide, particulate matter, and heavy metals per unit of energy than any other fuel source and impairs global public health. Coal ash disposal exposes communities to heavy metals and particulate matter waste. Use of coal in domestic households causes public health harm concentrated in developing nations. Across the coal continuum, adverse impacts are disproportionately felt by persons of poor socioeconomic status, contributing to health inequities. Despite efforts to develop renewable energy sources, coal use has not declined on a global scale. Concentrated efforts to eliminate coal as an energy source are imperative to improve public health and avert serious climate change consequences.
