“…No entanto, pouco se conhece sobre a relação entre os estressores ambientais e a suscetibilidade dos organismos em responder a esta exposição (Koeman et al, 1993). A utilização de plantas como bioindicadores e/ou biomonitores há muito vem sendo desenvolvida com o objetivo de detectar o impacto e a poluição ambiental causados pelas diversas atividades industriais e urbanas (Wiersma et al, 1980;Sant'Anna et al, 2008), seja em programa de biomonitoramento passivo, quando as espécies já se encontram no ecossistema, ou ativo, quando os organismos são introduzidos (Klumpp, 2001;Oliva & Figueiredo, 2005). De acordo com Jones & Heck (1980), as plantas são excelentes monitores biológicos de poluentes atmosféricos, pois apresentam uma sensibilidade relativamente maior em relação aos animais, possuem uma grande variabilidade genética entre e dentro das espécies, o que facilita a seleção do cultivar, da variedade e/ou do clone mais sensível, exibem sintomas foliares característicos de exposição a poluentes.…”

Resumo O presente estudo objetivou avaliar o potencial das espécies Anacardium occidentale L., Miconia albicans (Sw.) Triana e Byrsonima sericea DC. como acumuladores de alumínio (Al), arsênio (As), cobre (Cu), níquel (Ni), zinco (Zn) e enxofre (S), provenientes das emissões atmosféricas do Pólo Industrial de Camaçari (PIC). As concentrações dos elementos foram determinadas nos tecidos foliares de três indivíduos adultos por espécie. Os dados mostraram que M. albicans é uma espécie acumuladora de Al, Cu e S. Esta espécie apresentou sintomas de danos causados pela poluição atmosférica com cloroses e necroses sobre as folhas. Por outro lado, em A. occidentale e B. sericea a acumulação dos poluentes nos tecidos foliares foi, via de regra, menor. Em geral, os teores de Zn foram semelhantes em todas as espécies, enquanto as concentrações de As e Ni apresentaram valores abaixo do limite de quantificação. M. albicans demonstrou ser uma espécie com potencial para ser utilizada como biomonitor da poluição atmosférica no PIC.

“…The rising O 3 level in the atmosphere affects the growth rate of plants and induces visible foliar injury. It is well known that plants such as tobacco (Saitanis et al 2001;Pasqualini et al 2001;Sant'Anna et al 2008), (Finnan et al 1996;Meyer et al 2000;Pleijel et al 2003), soybean (Morgan et al 2003;Booker and Fiscus 2005;Bulbovas et al 2007), potato (Enyedi et al 1992;Pleijel et al 2003), grape (Grantz et al 1995), and others have their growth and physiology adversely affected by exposure to ozone. However, the interaction between O 3 and carbon dioxide (CO 2 ) in plant uptake has been also investigated as an important issue related to global climate change (Lawson et al 2001).…”

An experimental laboratory was designed and assembled at the Botanical Institute of São Paulo, Brazil, in order to research atmosphereplant interactions through the use of a system of fumigation chambers. A system of three "closed" fumigation chambers was designed to be used inside or outside the laboratory. The system was built to be used with a single pollutant or a mix of them. The innovation in this system is to allow chemical reactions inside the chambers that simulate atmospheric chemistry, especially photochemical processes involving high levels of ozone. Assessment of the performance and applicability of the system was based on the response of Nicotiana tabacum Bel W3 exposed to ozone produced alternatively by a generator and inside the chamber by reactions of its precursors. The results showed that the system can be well applied to the study of atmospheric chemistry interactions and the effects on plants.

“…Although Bel-W3 bio-monitoring systems have been used worldwide (Alves et al 2011; Calatayud et al 2007; Heggestad 1991; Klumpp et al 2006; Lorenzini 1994; Sant'Anna et al 2008), there is little information about the effects of chronic O3 exposure on Bel-W3. Some studies have shown that pre-exposing Bel-W3 to low doses of O3 predisposes the plant to O3 damage (Heagle and Heck 1974; Steinberger and Naveh 1982).…”

BackgroundSince 1962, the tobacco variety Nicotiana tabacum cv. Bel-W3 has been used worldwide as an ozone (O3) bio-indicator. The use of indicator plants to monitor O3 pollution has proven problematic when trying to correlate the severity of injury to ambient O3 concentration. The aim of the present study was to study factors affecting the O3 sensitivity of Nicotiana tabacum cv. Bel-W3 seedlings.ResultsIn chronic O3 pre-exposure tests, tobacco plants were cultured from seeds in charcoal-filtered air (CF) and noncharcoal-filtered ambient air (NF) for 21 days. During these periods, the mean O3 concentrations of the CF and NF treatments were 5.5 ± 0.2 and 14.7 ± 0.4 ppb h-1, respectively (p < 0.001). At the end of the culturing period, no O3-induced foliar injury was observed in any of the plants. The O3 sensitivity of the tobacco plants was determined by exposing the plants to 150 ppb O3 for 8 hours in a fumigation chamber. The leaf injury index percentages (LII%) of indicator plants via the CF and NF treatments were 58.0 ± 3.2% and 43.1 ± 4.0%, respectively (p < 0.01). Twenty-one-day-old tobacco seedlings grown in NF air were used to test the effects of exposed leaves on O3 sensitivity. After removing the cotyledons and all true leaves, the NF seedlings with their apical buds intact were transferred to CF air. After another 7 days of culturing, the newly developed leaves were approximately 1 cm in length. After O3 treatment, the LII% values of the newly developed leaves from the untreated and defoliated seedlings were 2.5 ± 1.7% and 27.6 ± 1.3%, respectively (p < 0.001). In acute O3 exposure tests, 21-day-old seedlings grown in CF air were fumigated with 150 ppb O3 for 8 hours in one day or for 4 hours/day in two consecutive days. The LII% values for the two groups were 63.5 ± 7.4% and 20.1 ± 4.3%, respectively (p < 0.001).ConclusionsThe present findings suggest that plant pre-exposure to O3 is a critical factor influencing O3 sensitivity and that exposed leaves obtain acquired tolerance against O3 injury later on.Electronic supplementary materialThe online version of this article (doi:10.1186/1999-3110-54-21) contains supplementary material, which is available to authorized users.
