The use of leaves of Rosmarinus officinalis L. as samplers for polycyclic aromatic hydrocarbons. Assessment of air quality in the area of Palermo
The quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) in vegetables and animals allows us to evaluate the quality of air, in a determined geographic area, without the need of making long samplers with complicate instrumentation. In this work, Rosmarinus officinalis leaves have been used as passive samplers. In particular, this plant was chosen because it is widespread in the Mediterranean area and it is commonly found both in the metropolitan and in the peripheral areas of the city of Palermo. Results for the concentration of total polycyclic aromatic hydrocarbons (the sum of the 22 compounds) and the PAHs distribution in leaves from Rosmarinus officinalis are presented. Puri…
Sand clams of Ganzirri marine coastal lagoon in Messina (Italy). Extraction and ICP-MS analysis
This paper studies the possible forms or phases of heavy metals in sediments of a marine coastal lagoon, called Ganzirri, located in the Sicilian coast of the Messina’s strait by using sequential extraction. To reduce the extraction time of the Tessier method, the last step of speciation was carried out by mineralization in a microwave oven. Here we report the results of the distribution of As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, Se, Tl, V and Zn, in four fractions of sediments samples and the concentration of the same metals in clams. This study looked at three bivalve mollusc species, Tapes decussates, Chamelea gallina and Cardium edule, raised in the sediment considered and discussed the…
Adsorption of polyciclic aromatic hydrocarbons (PAHs) by pine barks and their use for environmental pollution monitoring in the Palermo (ITALY) area
Pelargonium leaves as bioaccumulator of polynuclear aromatic hydrocarbons: Analysis and evaluation of sources and air quality in Palermo area
The leaves of Pelargonium zonale have been chosen because this plant is widespread in both the Mediterranean metropolitan and peripheral areas. The paper describes the analytical method, and the results concerning the determination of PAHs in Pelargonium leaves collected in the Palermo area, and their possible origins. The GC-MS method was applied, since identification of all the different compounds with spectra libraries is possible. Samples were analyzed for 22 PAHs. The reported analytical method is complete within 2 hours, and more convenient than that of other researches. Total PAH concentrations in leaves varied between 24-357 g/kg d.w. The relative abundance of the analyzed PAHs can …
