“…The state of Espírito Santo (Brazil) has the largest iron production of the country, being the biggest mining harbor in Brazil (IBEF, 2011). Levels of iron in sediments of this area reach 23 mg g À1 (Arrivabene et al, 2015), which are above levels found in other polluted mangrove areas (Defew et al, 2005;Lacerda et al, 1989;Sadiq and Zaidi, 1994;Sarangi et al, 2002;Sherman et al, 1998;Silva et al, 1990).…”

Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle were experimentally exposed to increasing levels of iron (0, 10, 20 and 100 mg L(-1) added Fe(II) in Hoagland's nutritive medium). The uptake and translocation of iron from roots to stems and leaves, Fe-secretion through salt glands (Avicennia schaueriana and Laguncularia racemosa) as well as anatomical and histochemical changes in plant tissues were evaluated. The main goal of this work was to assess the diverse capacity of these plants to detect mangroves at risk in an area affected by iron pollution (Vitoria, Espírito Santo, Brazil). Results show that plants have differential patterns with respect to bioaccumulation, translocation and secretion of iron through salt glands. L. racemosa showed the best environmental sensing capacity since the bioaccumulation of iron in both Fe-plaque and roots was higher and increased as the amount of added-iron rose. Fewer changes in translocation factors throughout increasing added-iron were observed in this species. Furthermore, the amount of iron secreted through salt glands of L. racemosa was strongly inhibited when exposed to added-iron. Among three studied species, A. schaueriana showed the highest levels of iron in stems and leaves. On the other hand, Rhizophora mangle presented low values of iron in these compartments. Even so, there was a significant drop in the translocation factor between aerial parts with respect to roots, since the bioaccumulation in plaque and roots of R. mangle increased as iron concentration rose. Moreover, rhizophores of R. mangle did not show changes in bioaccumulation throughout the studied concentrations. So far, we propose L. racemosa as the best species for monitoring iron pollution in affected mangroves areas. To our knowledge, this is the first detailed report on the response of these plants to increasing iron concentration under controlled conditions, complementing existing data on the behavior of the same plants under field exposure.

“…Other stressors, such as road construction and the deposition of black dust on leaves and sediment (Personal observation), may explain the mortality at point 1B. The presence of iron ore dust on tree leaves in the study area was tested by ARRIVABENE et al (2015), who observed no morphological or structural damage. However, decreased energy from light incident on plant tissues may reduce photosynthetic performance (NAIDOO;NAIDOO, 2005).…”

The structural heterogeneity of an urbanised mangrove forest area in southeastern Brazil: Influence of environmental factors and anthropogenic stressors

et al. 2016

The objective of this study is to evaluate the characteristics of the forest in an urbanised mangrove using vegetation structure and abiotic conditions to distinguish habitat heterogeneity/quality. A total of 16 points in Vitória Bay were selected in the fringe and basin forests. The variables evaluated were height and diameter of the individual trees, basal area, density, dominance, interstitial water, litter mass, grain size, organic matter and anthropogenic influences. The results indicated that the mangrove area, due to suffering intensely from various anthropogenic effects, forests with varying degrees of maturity. Areas more distant from direct human effects had a higher degree of development and environmental quality relative to points closer to urban pressures. Intermediate development levels were also observed, which indicated pulses of environmental change. Human interventions caused alterations in the development of the forest which increased the mortality rate and reduced the diameter and height of the trees. The environmental variables of salinity, organic matter, litter mass, grain size and anthropogenic stressors contributed to the structural patterns. Our data suggest that an analysis of the vegetation structure and the abiotic factors are useful indicators to evaluate habitat quality, thus providing a basis for future management.

“…4(d)). Iron concentrations, measured in a previous study in leaves of Avicennia schaueriana (up to 332.7 µg g -1 ) and Laguncularia racemosa (up to 300.9 µg g -1 ) collected from mangrove areas with high particulate iron pollution (Arrivabene et al, 2015), were still lower than those obtained at the current roadside sites. There are various inorganic elements in atmospheric aerosols, among which iron is one of the highest content (Li et al, 2005).…”

As the capital of China, Beijing is continuously exposed to high amount of airborne dust, thus it is necessary to find improvement methods. Taking advantage of phytoremediation, an ecological and friendly way to improve air quality, this study investigates the role of urban plant leaves in removing airborne dust and its associated metals by analyzing leaf samples of 32 plant species in autumn. Results showed that leaves could remove dust from 0.510 to 23.0 g m -2 with an overall mean of 7.50 g m -2 on Beijing roadside sites. Some species removed certain metals more efficiently than others.
