“…All these studies showed similar patterns, where urban zones have high concentrations of Cd, Cu, Pb and Mn [20,21,33,35,52]. However, the concentrations of these heavy metals in our control site (Forest) were relatively low [9,41,42,60]. This would suggest that the overall background contamination by heavy metals in Ecuador might generally be quite low; thus, the air in rural areas goes largely unaffected and an increased concentration is present only in the city itself [46].…”

We evaluated heavy metal deposition in Parmotrema arnoldii and Tillandsia usneoides in response to air pollution in Loja city, Ecuador. We assessed heavy metal (cadmium, copper, manganese, lead and zinc) content in these organisms at nine study sites inside Loja city and three control sites in nearby forests. Concentrations of all studied heavy metals (i.e., cadmium (Cd), copper (Cu), lead (Pb), manganese (Mn) and zinc (Zn)) were highest in downtown Loja. Our study confirms that passive monitoring using lichens and/or bromeliads can be an efficient tool to evaluate heavy metal deposition related to urbanization (e.g., vehicle emissions). We recommend these organisms to be used in cost-effective monitoring of air pollution in tropical countries.

The aim of this research was to determine the concentrations of calcium, iron, manganese, zinc, potassium and sodium in the water and leaves of Aechmea blanchetiana (Baker) L.B species collected between the cities of Ilhéus and Itacaré, Bahia, Brazil and verify if the metals found in the water can be absorbed by the leaves. Flame atomic absorption spectrometry (F AAS) and flame photometry were used for the determination of metals. pH measurements, dissolved oxygen and water temperature were also made. The results obtained were used in an exploratory analysis. Principal component analysis (PCA) showed clearly the distinct formation of two clusters and the correlation analysis indicated that the leaves of A. blanchetiana seem to absorb iron, calcium, manganese and zinc from the water tank.Keywords: Bromeliaceae; Aechmea blanchetiana; metals; water and leaves. INTRODUÇÃOA Aechmea blanchetiana (Baker) L.B é uma espécie da família Bromeliaceae Juss., um importante táxon vegetal, com 58 gêneros e 3.172 espécies.1 O embricamento das folhas em forma de roseta, em muitas espécies, forma um reservatório (fitotelma) onde se acumula água e nutrientes, por isso essas bromélias são conhecidas como bromélias-tanque. Este microhabitat é utilizado como abrigo e para reprodução por diversos organismos, como algas, bactérias, anfíbios, rép-teis e insetos, sendo inclusive o único ambiente onde algumas espécies podem sobreviver.2 Esses organismos deixam restos de suas atividades metabólicas no reservatório, tornando-o um local rico em nutrientes e um importante microhabitat nos ecossistemas dos quais fazem parte.3 Na família Bromeliaceae a captação de nutrientes também ocorre pelos tricomas foliares, especialmente as bromélias epífitas, que utilizam essas estruturas como única forma de obtenção de água e nutrientes. 4 Estes tricomas acabam absorvendo também poluentes atmosféricos e, por isso, são muito úteis para o biomonitoramento de contaminação atmosférica. 5,6 Essa característica faz com que esses organismos sejam bastante utilizados como uma ferramenta efetiva e de baixo custo para a avaliação da deposição de elementos traço. 7,8 Zampieri et al. avaliaram a absorção e translocação de Ca, Co, Fe, K e Zn em Aechmea blanchetiana com plantas cultivadas in vitro em meios de cultivo contendo diferentes concentrações de Zn. A espécie apresentou tolerância a altos níveis do metal, possibilitando a utilização no biomonitoramento de áreas contaminadas por Zn. Giampaoli et al. estudaram o crescimento e desenvolvimento de Aechmea blanchetiana com plantas in vitro na presença de Cu e Zn. Acúmulo significante ocorreu para os dois elementos, caracterizando a espécie como capaz de bioacumular esses metais.10 Além de absorver água e nutrientes, alguns autores citam as bromélias como fontes de criadouros de Aedes aegypti. 11,12O uso de organismos vivos na caracterização ambiental tem sido cada vez mais frequente, uma vez que estes auxiliam no mapeamento espacial e temporal da poluição atmosférica e das oscilações naturais ocorridas nos ecossiste...

“…Regarding the bioaccumulation capacity of atmospheric pollutants by epiphytic Tillandsia genus, Tillandsia capillaris has proved to be an excellent bioaccumulator of trace elements (TE) in the areas surrounding complex polymetallic mining/smelting in Oruro, Bolivia[141,142]. In Argentina, this species has been widely used to determine polycyclic aromatic hydrocarbons (PAHs)[140], physiological parameters and accumulation of trace elements in different contexts (urban, agricultural, industrial, and mining)[51,138,[143][144][145][146].…”

“…Biomonitoring air quality study has rapidly increased over recent decades as an inexpensive and efficient alternative where are used different bio-organisms such as lichen, mosses, tree bark, and Spanish mosses (bromeliad genus) methods, which have been widely used to estimate air pollution, especially of airborne elements during determined period time, low cost, and in several geographical areas simultaneously.Tillandsia genus or air plants are epiphytic plants of the Bromeliaceae family, which are widely distributed on their native habitat in the southern United States, Central, and South America, with a large number of species. These species grows slowly, has an extraordinary ability to obtain water and nutrients from the atmosphere through their leaves called trichomes and are resistant to hydric stress[169].Among all the species, Tillandsia usneoides and/or Tillandsia capillaris have been more employed as biomonitors of toxic trace elements in Argentina, Bolivia, Brazil, Italy, Mexico, USA, and Thailand[71,141,142,144,151,[170][171][172], and in Chile, Mexico and Paraguay were used Tillandsia recurvata[83,173,174].…”
