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.

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

Fine particles and human health: a review of epidemiological studies
TL;DR: In this paper, the role of particle size and particle composition was discussed, and the effect of particle number and composition on health effects of exposure to ultrafine particles was investigated in numerous epidemiological studies.

Excitotoxic and excitoprotective mechanisms: abundant targets for the prevention and treatment of neurodegenerative disorders.
TL;DR: Considerable evidence supports roles for excitotoxicity in acute disorders such as epileptic seizures, stroke and traumatic brain and spinal cord injury, as well as in chronic age-related disorderssuch as Alzheimer's, Parkinson’s, and Huntington's disease and amyotrophic lateral sclerosis.

TL;DR: The response of RAW264.7 cells to ambient PM was markedly different using samples collected at various sites in the Netherlands that differed in their local PM emission sources, in support of other investigations showing that the chemical composition as well as oxidative potential are determinants of PM induced toxicity in vitro.
