Atmospheric Pollutants and the Occurrence of Bromeliads in Electric Power Distribution Network

Abstract

-The occurrence of atmospheric bromeliads (Tillandsia spp. -Bromeliaceae) in the structures of electric power distribution networks is a problem for energy concessionaires. A research project is underway to investigate possible factors contributing to bromeliad occurrence in these structures. One stage of the project is to evaluate the correlation between atmospheric pollutants and the occurrence of bromeliads in urban electric network cables using atmospheric dispersion modelling. The results indicate a correlation between pollutants and infestation of bromeliads in regions with higher vehicular than industrial emissions in the study area (Ponta Grossa city, Paraná State, Brazil).
