A ocorrência das bromélias atmosféricas (Tillandsia sp) nas redes de distribuição de energia proporciona um efeito visual negativo e custos de limpeza para as empresas. Apesar dos estudos existentes, as informações não explicam quais as condições propícias para o fenômeno. Para se obter dados sobre a qualidade do ar em Curitiba, tendo em vista que as bibliografias apontam este gênero como uma planta bioindicadora, foi realizada uma modelagem da dispersão de poluentes atmosféricos através do programa AERMOD, utilizado pela United States Environmental Protection Agency. Foram simuladas as concentrações dos poluentes: material particulado, óxido de nitrogênio, hidrocarbonetos totais, monóxido de carbono e dióxido de enxofre. Foram levantados 26 pontos dentro do perímetro urbano com a presença das bromélias nos cabos. Nestes pontos foram observadas as fontes emissoras atmosféricas, presença de vegetação e tipo de área do zoneamento municipal. Através da modelagem foi possível determinar os valores médios e máximos das concentrações dos poluentes medidos, entre 2007 a 2011. O tratamento estatístico utilizando a Análise de Componentes Principais indicou uma correlação entre fontes antrópicas, em sua maioria móveis e de emissões veiculares que combinadas a fatores atmosféricos propiciam condições para a presença das bromélias nos cabos. INTRODUÇÃOA Agência Nacional de Energia Elétrica (ANEEL) é a instituição que regula as questões relativas à geração e distribuição de energia no Brasil. A ANEEL realiza inspeções nas redes de distribuição em todo o país muitas vezes encontrando grandes quantidades de bromélias estabelecidas sobre os cabos dentro do perímetro urbano das cidades e em áreas rurais. A limpeza dos cabos é feita manualmente pelas concessionárias com elevados custos e sendo que novas infestações sempre são recorrentes. A solução deste tipo de problema passa pelo estudo das condições fisiológicas e de crescimento da planta e pela análise detalhada do ambiente do entorno destas ocorrências bem como da proposição de soluções preventivas que evitem a novas infestações.

Batteries have been increasingly used as energy storage tools associated with the generation of solar and wind energy, contributing to the reduction of negative environmental impacts. However, as much as there is a reduction in impacts, when compared to other forms of energy generation, it is still relevant to analyze the environmental risks and impacts that may be linked to Energy Storage Systems (ESS). This study presents an analysis of environmental risks and impacts related to ESSs, based on lithium-ion (Li-ion) batteries, of a photovoltaic plant located in the Northeast of Brazil. The applied methodology involved two techniques: the Bow Tie method, for the analysis of environmental risks, and the Interaction Matrix method, for the analysis of environmental impacts. Within the scope of the Bow Tie method, diagrams of the situations relevant to this study were generated, identifying causes and consequences, as well as prevention and mitigation actions for each risk. The main environmental risks found were of fire and/or explosions and environmental contamination. In the event that these risks occur, the environmental impacts associated with the physical, biotic and anthropic environments, as well as with the phases of the Li-ion ESSs (operation and decommissioning), were also identified through the Interaction Matrix, which confirmed the importance of applying preventive and appropriate measures for the listed risks, in order to, as much as possible, avoid a wide range of impacts on the environment. Through this study, it was possible to highlight both the importance of the appropriate care for the protection of the environment and for the safety of the plant's employees and the surrounding community.

-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).

The occurrence of atmospheric bromeliads (Tillandsia spp.-Bromeliaceae) in the structures of electric power distribution networks is a problem for energy concessionaires. It causes the impression of abandonment and energy distributors do not have enough information to understand the impacts caused by this infestation. 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. This was made by using principal component analysis to evaluate the correlation between atmospheric pollutants concentration obtained by dispersion modelling and field data of bromeliad abundance. 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).
