While these studies represent important contributions, especially given the paucity of data in the area, they are fairly narrow in terms of methodological approaches and geographical setting.
Also, meteorological and geographical parameters are recorded.
To do so, we quantify the effect of the different methodological approaches, and temporal and geographical coverage.
As such, it illustrates the complexities and many caveats inherent to research on the effective use of forensic science and identifies limitations pertaining to methodological approaches, opportunistic sampling, demographical and geographical circumscription of the research, among others.
As might be expected in a multi-site study, there were some differences observed between sites, and these are likely to be due to a combination of procedural and methodological differences, as well epidemiological and geographical variation.

In addition to the methodological differences noted above, differences in results across studies may also be explained by actual differences in PM2.5 composition over time and geographical area due to pollutant sources and meteorological conditions (Bell et al. 2007).
"Emotional, physical and geographical space".
This has two dimensions – temporal and geographical.
It is religious, generational, moral and geographical.
