Briófitos como indicadores de calidad de aire una revisión sistemática

Abstract

Abstract: Bioindicator organisms such as bryophytes are considered bioaccumulative, tolerant and to some degree sensitive to contaminated environments. Air quality assessment in urban areas can be performed by two types of biomonitoring: passive (native species) and active (transplanted species). The present study aims to develop a list of urban bryophyte species more suitable to measure air pollution and the elaboration of recommended protocols for airquality assessment, through a systematic review from 2000 to 2020 of 70 articles published in some virtual databases (Scopus, Isi Web, ScienceDirect). As a result of this systematic review 2 studies referring to active and passive monitoring, 51 studies of passive monitoring with representative species such as Scleropodium purum and Pleurozium schreberi were obtained and for active monitoring there were 17 studies where species such as Hypnum cupressiforme and Pseudoscleropodium purum were used, besides the metals that were mostly evaluated are Cr, Pb, Zn and Cu. The application of active and passive monitoring protocols can be of great help in establishing controls and reducing emissions of air pollutants.
