TL;DR: In this article, the authors measured mass concentrations of particulate matter with diameters ≤ 2.5 μm (PM2.5), ≤ 1.0 μm(PM1.0), and ≤ 0.5 µm (μm 0.1) and found significant associations of greater concentrations of PM in different size fractions within 5 days before blood collection with lower HDL-C and apolipoprotein A (ApoA1) levels, higher apoliprotein B (APoB) levels and lower ApoA1/ApoB ratios

TL;DR: In this paper, the authors conducted a study on the associations between particle size and constituents and blood pressure, and the results have been inconsistent, although the particle size was positively associated with blood pressure.

TL;DR: Wang et al. as discussed by the authors found that an interquartile range (45.9 μg/m3) increase in PM2.5 concentration was significantly associated with increments of 16.6, 3.4, 12.3, and 8.8% in C-reactive protein (CRP), monocyte chemoattractant protein-1 (MCP-1), soluble vascular cell adhesion molecule-1, and endothelin-1(ET-1).

TL;DR: This study demonstrated that short-term exposure to PM2.5 and PM1.0 was deleteriously associated with the HCY metabolism markers, especially in people with lower B vitamins levels.
