Bromelias como indicadores de la calidad del aire, una revisión sistemática

Abstract

Abstract:Bromeliads have been widely used in active and passive monitoring of air quality. However, a systematic review providing this information is not yet available. The objective of this work was to generate information on how many articles were published between 2000 and 2020 and a listing of bromeliad species. Using an adaptation of the PRISMA methodology and systematic review methodology, 30 scientific articles were identified and subjected to a literature review. The neotropical region with 21 articles and the palearctic region with 5 articles were the most influential regions. Passive monitoring registered 16 articles compared to active monitoring with 14. A total of 18 species of the family bromeliaceae were found, predominating the genus Tillandsia. Tillandsia usneoides was the most common species used in active and passive monitoring while Tillandsia recurvata was for passive monitoring. The measurement of heavy metals was the preferred technique (93% of the studies) for air quality monitoring where Zn, Fe, Pb, Cr and Cu; and the non-essential elements K, Ca and Na were the most measured. Finally, a protocol was proposed to facilitate or standardize the choice of methodology for the development of air quality monitoring.
