From: Particulate matter exposure shapes DNA methylation through the lifespan

Effects of PM on DNA methylation throughout the lifespan. PM affects DNA methylation with an impact on health during all the life stages, from preconception to the elderly. The most studied life stages are pregnancy and the adult age. The reported evidences indicate that pregnancy, childhood, and the elderly can be considered hypersusceptibility windows (reported as red in the heat bar; green represents less impacted time windows)
