From January to April 2009, samples of suspended particles (TSP) and particulate matters (PM10 and PM2.5) were collected from a well-characterized urban area that is highly impacted by vehicular traffic. The metal concentrations in these samples were determined using ICP-OES (inductively coupled plasma-optical emission spectroscopy). Ca, Mg, Fe and Al were the most abundant metals present in TSP and PM10, with concentrations higher than 427 ng m-3. In PM2.5, the most abundant metals were Fe and Ca (307 and 60 ng m-3, respectively), while the concentrations of Mg, Zn and Cu were approximately 20 ng m-3. For PM10 and PM2.5, high correlations were obtained for Ca, Mg and Al, while the correlation of Ca and Mg with Fe was poor, thereby indicating that Ca, Mg and Al probably originate mainly from the resuspension of dust, while Fe may also be originated from an additional source, such as brake wear. Anthropogenic elements (Zn and Cu) had low correlation factors, suggesting different emission sources. The presence of Cu may be linked to the abrasion of brakes, and Zn may be attributed to tire wear. In fine particles, Ca, Mn, Fe, Zn and Cu were present in higher ratios than in crustal material. Because these particles are mainly observed due to the combustion processes, they may be present in gasoline, oil and lubricants. Fe was correlated with Mn, while correlation factors between Ca and Mg were relatively lower. |

This work was carried out to evaluate the development of native species in degraded areas in Araripe region of Pernambuco State. The experiment was established in an area of an Experimental Station of the Instituto Agronômico de Pernambuco (IPA) in Araripina-PE. (Latitude: 7°27'50"S, Longitude: 40°24'38"W, height: 828m). The experimental area was previously subjected to plowing and harrowing in order to incorporate into the soil 2.0 t ha-1 of dolomitic limestone. Base fertilization was done with 100 g hole-1 NPK (10:80:30). The planting was done in hills of 30 x 30 x 30 cm, spaced 4 x 4 m. The experimental design was in randomized blocks with five replications and six treatments: angico [Anadenanthera colubrina (Vell.) Brenan], angico de bezerro [Piptadenia obligua (Pers.) Macbr.], aroeira [Myracroduon urundeuva Allemão], jurema preta [Mimosa tenuiflora (Willd.) Poiret.], pau d'arco [Handroanthus impetiginosus (Mart. ex DC.) Mattos] and sabiá (Mimosa caesalpiniifolia Benth.). ?Sabiá? species, with 1.68 m height, overcame all other species at twenty-four months of age, while ?aroeira? species showed the lowest growth (0.34m). There were no statistically significant differences among the studied species, showing that they are adapted to the environment for being native to the region. |
