Vertical distribution of ambient air pollutants (PM_2.5, PM₁₀, NO_X, and NO₂); A systematic review.

ABSTRACT:

Background

Numerous investigations have explored variations in vertical air pollutant concentrations, yielding diverse findings. So, we have conducted this systematic review to gain a more comprehensive understanding of the vertical distribution of air pollutant concentrations (PM_2.5, PM₁₀, NO_X, and NO₂) and the influencing factors.

Methods

Relevant studies were identified by searching the three central electronic databases, PubMed, Web of Science, and Scopus, from the beginning of 2000 to the end of 2023. This study included original articles published in English that examine the pollutant concentration variations below 500 m.

Finding

Of 3614 articles, 57 studies met our criteria. Our findings showed a decline in PM_2.5
