TL;DR: This study suggests that year-specific model for 1991 and back-extrapolation of the 2009 LUR yield similar exposure assessment, with best performance from the subset of sites representing population exposures.

TL;DR: Land-use regression predictive ability in terms of holdout validation and cross–holdout validation rather than leave-one-out cross-validation was associated with the magnitude of health effect estimates in a case study.

TL;DR: In this paper, five different methods for measuring the concentrations of ambient air particles were compared in downtown and suburban areas of a medium sized Northern city in winter and spring: namely total suspended particulates (TSP) measured by HiVol and dichotomous samplers, particles < 10 μm (PM10) measured with a PM10 impactor and a dichotomyous sampler, black smoke (BS), and size fractionated particles measured by an electrical aerosol spectrometer (EAS).

TL;DR: Long-term exposure to PM2.5 was associated with increased levels of liver enzymes, especially ALT and GGT, especially in adults who participated in a standard medical screening programme in Taiwan.

TL;DR: The conclusion that in the Netherlands SO2 does not seem to be a causative factor for PM associated health effects is substantiated by further circumstantial evidence, in combination with biological arguments, indicating that a factor correlating with SO2 (probably PM) might explain the observed associations with total mortality.
