The cellular effects of PM2.5 collected in Chinese Taiyuan and Guangzhou and their associations with polycyclic aromatic hydrocarbons (PAHs), nitro-PAHs and hydroxy-PAHs
TLDR
In this paper, the effects of region and season-dependent differences of PM2.5 on cytotoxicity, and the contributions of PAHs, nitro-PAHs (N-PAHLs) and hydroxy-PAHSs (OH-PAHRs) to PM2., were examined by determining different toxicological indicators in three lung cell lines.About:

Air pollution and health
TL;DR: The effects of air pollution on health have been generating attention for years as mentioned in this paper, and a large number of pulmonologists have recently expressed concerns about this in an open letter to Dutch Members of Parliament.
Journal ArticleDOI

TL;DR: This review provides guidance to prepare and plan efficient sampling campaigns to collect sufficient PM mass for various purposes in a reasonable timeframe and highlights that predictive modelling can help to identify pollution hotspots in an urban environment for the efficient collection of PM mass.

Exposure to Atmospheric Particulate Matter-Bound Polycyclic Aromatic Hydrocarbons and Their Health Effects: A Review.
Lu Yang,Hao Zhang,Xuan Zhang,Wanli Xing,Yan Wang,Pengchu Bai,Lulu Zhang,Kazuichi Hayakawa,Akira Toriba,Ning Tang +9 more
TL;DR: In this paper, a review of personal exposure, and indoor and outdoor PM-bound PAH concentrations for different participants, spaces, and cities worldwide in recent years is presented, in which the main aims are to clarify the characteristics of PAHs under different exposure conditions, in addition to the health effects and assessment methods.

Oxidative Potential Induced by Ambient Particulate Matters with Acellular Assays: A Review
Lanfang Rao,Luying Zhang,Xingzi Wang,Tingting Xie,Shumin Zhou,Senlin Lu,Xinchun Liu,Hui Lu,Kai Xiao,Weiqian Wang,Qingyue Wang +10 more
TL;DR: Several typical OP measurement techniques, including the respiratory tract lining fluid assay (RTLF), ascorbate depletion assay (AA), dithiothreitol assay (DTT), chemiluminescent reductive acridinium triggering (CRAT), dichlorofluorescin assay (DCFH) and electron paramagnetic/spin resonance assay (EPR/ESR) are discussed and their sensitivity to different PMs species composition, PMs size distribution and seasonality

Proinflammatory effects and oxidative stress within human bronchial epithelial cells exposed to atmospheric particulate matter (PM(2.5) and PM(>2.5)) collected from Cotonou, Benin.

TL;DR: The findings showed the ability of both PM to induce oxidative stress and to cause inflammatory cytokines/chemokines gene expression and secretion, and PM were able to induce gene expression of enzymes involved in the xenobiotic metabolism pathway.

Particle size, chemical composition, seasons of the year and urban, rural or remote site origins as determinants of biological effects of particulate matter on pulmonary cells.

TL;DR: The first-time here reported biological responses induced by PM from a remote site at high altitude were associated with the high concentrations of metals and secondary species typical of the free tropospheric aerosol, influenced by long range transports and aging.

TL;DR: The results of the current study corroborate that short-term bioassays using lung human cells and abiotic assays, such as the DTT assay, could be relevant to complete the routine chemical analysis and to obtain a preliminary screening of the potential effects of PM-associated airborne pollutants on human health.
Journal ArticleDOI
Effects of ambient PM2.5 on pathological injury, inflammation, oxidative stress, metabolic enzyme activity, and expression of c-fos and c-jun in lungs of rats.
TL;DR: In this paper, the authors showed that PM2.5 exposure induced inflammatory cell infiltration and hyperemia in the lung tissues and increased the inflammatory cell numbers in bronchoalveolar lavage fluid.
