| Title | Assessment of atmosheric heavy metal deposition in the Taranto urban area using the moss biomonitoring techimique and ICP-MS analysis. |
| Abstract | Biomonitoring using mosses is a well-developed technique
employed in many parts of the world to assess the concentrations
of trace elements in the atmosphere and their potential sources.
The stability of metal organic complexes and chelates and the great
cation exchange capacity of the tissues are primarily conditions for
the sorption of heavy metals by mosses. The use of mosses as passive
biomonitors for analysis of atmospheric deposition has been
reported in a large number of studies in different parts of the world.
The moss technique is particularly favourable for estimation of
long-term temporal and spatial changes in metal deposition. Bioaccumulation
monitoring methods can be divided into two groups:
active and passive. Active monitoring includes the exposure of
well-defined species under controlled conditions, whereas passive
monitoring refers to the observation or chemical analysis of indigenous
bryophytes. Mosses are well suited to this purpose because
they receive metals directly from the atmosphere and efficiently
retain a number of elements. In this study, a biomonitoring of
heavy metal (Cd, Cr, Ni, Cu, Mn, Pd, Hg, V, As, Fe, Al, Mn) in the
urban Taranto area has been conducted through mosses belonging
to the autochthonous species, Pleurochaete squarrosa and Hypnum
cupressiforme. Active and passive monitoring methods were used
to evaluate air quality and metal contamination in the atmospheric
depositions. Samples of epigeouses mosses were taken in areas
exposed to different human impacts. Surveys were conducted in
different seasons in order to correlate metal contamination levels
with climatologic factors. The analyzed metals were those originated
both from industrial area (ILVA-Iron and Steel factory, ENIRefinery)
and from vehicular traffic. The results of air monitoring,
according to air quality indexes determined by automatic stations,
confirmed that Pleurochaete squarrosa and Hypnum cupressiforme,
are very good bioindicators for analysis of atmospheric metals contamination. |
