What The Sources Report

  • For example, Zhang et al.found that 22% of the 3.45 million mortalities caused by PMin the year 2007 resulted from trade among the 13 global regions they studied. [Wang Shiyuan (2026); evidence level 4]
  • We connect the MRIO models to an inventory of air pollutant emissionsand to a reduced-complexity model of air pollution transport, transformation, and removal. [Wang Shiyuan (2026); evidence level 4]
  • Recently, lichens have also been found to be highly responsive to rising air temperatures associated with global warming, offering promise to detect biological impacts of climate change in the natural environment on these slow-growing, long-lived organisms (Aptroot and van Herk ; Sancho et al. ; Stapper and John ). [Colesie Claudia (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

For air quality, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
