“…Natural inputs are also significant and include wind-blown soils from arid regions, agricultural soil emissions, forest fires and volcanic eruptions . Our findings showed a slight Ca enrichment in YOC, which is in agreement with Adejumo et al (1994) and Jasan et al (2004), who ascribed high Ca concentrations to cement plant emissions.…”

Purpose Heavy metals are especially dangerous because of their persistence and toxicity. Soil behaves as a sink of heavy metals by aerial deposition of particles emitted by different human activities. The aims of this work were to identify the levels and sources of heavy metal and trace elements in agricultural and residential areas in Argentina and to evaluate the enrichment of total and HCl-extracted heavy metals. Materials and methods Ninety-four topsoil samples were collected in Córdoba, Argentina (0-10 cm). The majority of the samples were subject to agricultural practices. The possible metal pollution sources were a cement plant and an industrial waste incinerator, a former open-cast uranium mine, petrochemical, and mechanical and metallurgical industries among others. The elements As, and Zn were measured by neutron activation analysis, and Co, Cu, Fe, Mn, Ni, Pb, and Zn were partially extracted by 0.5-M HCl and measured using atomic absorption spectroscopy. Several nonparametric statistics were performed to the dataset in order to accomplish the objectives of the study. Results and discussion The mean total Ba concentration exceeded soil quality guidelines for residential areas, with the maximum total As and Co concentrations surpassing the agricultural and residential limits stated in national and international legislations. The elements As and Ba were found to be controlled by parent factors, whereas Ca, Co, Cr, Cu, Mn, Ni, Pb, and Zn were controlled by both anthropogenic and pedogenic factors. A cement plant was the main source of Ca, Co, Cr, Cu, Mn, Ni, Pb, and Zn, whereas lanthanides, Fe, K, U, and also Zn were associated with a former open-cast operation uranium mine. A correlation analysis showed that soil organic matter and pH had strong associations with 0.5-M HCl-extracted Co, Cu, Mn, Ni, Pb, and Zn. Conclusions Fe-normalized enrichment factors calculated for 0.5-M HCl-extracted heavy metals are potentially significant for characterizing the element bioavailability, the anthropogenic contamination, and the anomaly assessment. According to soil quality guidelines for environmental health, the human and wildlife populations in Córdoba Province might be experiencing toxic As, Ba, Co, Cr, Ta, U, and Zn effects. Therefore, mitigation strategies should be performed on an abandoned mine (Schlagintweit Uranium Mine), Yocsina, Despeñaderos, and Oliva.

“…It has been successfully employed as a monitor of airborne lead and many other trace elements (Ward et al 1974;Laaksovirta et al 1976;Huhn et al 1995;Böhm et al 1998;Walkenhorst et al 1993). Some Argentine biomonitoring studies have used lichens, bryophytes and epiphytes in order to overcome the lack of suitable instrumental resources for the direct measurement of air quality (Graciano et al 2003;Jasan et al 2004;Pignata et al 2002;Carreras et al 2005), whereas bark has been used less frequently. Platanus acerifolia and Fraxinus pennsylvanica barks were employed to compare pollution levels in the city of Buenos Aires and nearby rural or periurban locations (Plá et al 2000;Perelman et al 2006).…”

Multi-elemental profiles in bark of green ash trees collected in three representative areas of Buenos Aires, Argentina and Montevideo, Uruguay, were assessed as potential air pollution indicators. Ten elements: Al, Ba, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Zn, were measured using inductively coupled plasma optical emissions spectrometry from 70 samples collected in different environments: central, residential and rural (reference site), in order to compare spatial patterns of metal concentration. The samples used as a control were collected from a nature reserve situated far away from any significant influences, not even a nearby road. The reference site (RF) exhibited the lowest concentrations of Al, Cr, Fe, Ni, Pb, and Zn. However, Ba and Mn showed similar concentrations in all measured sites. Magnesium is the only element that had a greater concentration in RF than at the other sites. Copper did not show any clear pattern. The Centre of Montevideo (MVD) showed higher concentrations of Al, Ba, Cr, Fe, Pb and Zn than the Centre of Buenos Aires (BA). In the A sectors, Montevideo (SAMVD) showed higher concentrations of Al, Cu, Mg, Ni, and Zn and lower concentrations of Ba, Cr, Fe, Mn, and Pb than Buenos Aires (SABA). In the B sectors, Montevideo (SBMVD) showed higher concentrations of Al, Ba, Cu, Fe, Pb, and Zn and lower concentrations of Cr and Mg than Buenos Aires (SBBA), but similar concentrations of Mn and Ni. The use of bark for biomonitoring metals allowed us to detect concentration differences related to the urban fabric and the different kinds of vehicles and their fuels. In the cities, the differences in metal concentrations detected in bark were more striking between the sectors than between centers, despite CBA being much larger than CMVD in population, extension and vehicular traffic.

“…INAA has been used for multiple applications: e.g., for the determination of Cr and Co in human serum (Versieck et al 1978) to investigate the absorption of Hg in algal biomass (Mosulishvili et al 2004), multielements in earthworms (Zheng et al 1997), the distribution patterns of rare earth elements and their binding species with proteins in humans (Chen et al 2001), heavy metals in different organs of fishes living in polluted environments (Wood et al 1990;Veado et al 2007), the impact of heavy metals from environmental tobacco smoke (Landsberger and Wu 1995), to characterize several biological reference materials and selected food items (Rao et al 1995), for air pollution research (Chung et al 1997;Jasan et al 2004;Wannaz et al 2008), and in the geological sciences, INAA is still considered the method of choice for multi-element studies requiring precision and accuracy (Koeberl 1993).…”

The objectives of this study were to determine the capacity of the freshwater calanoid copepod Argyrodiaptomus falcifer (Daday, 1905) to accumulate Cr from water, to know the bioconcentration factors in order to evaluate its potential as a biomonitor, and to compare this with data previously obtained with Daphnia magna Straus under identical conditions. By static bioassays using triplicates and a control, a pool of A. falcifer was exposed to three concentrations of Cr (VI): 150 μg/L (T1), 280 μg/L (T2), and 350 μg/L (T3) for 48 h to later determine by Instrumental Neutron Activation Analysis the amount of Cr accumulated. A. falcifer accumulated Cr in all the three concentrations tested. The comparison of T1, T2, and T3 and the control showed significant differences (p<0.05) but not between the treatments (p>0.05). On the other hand, A. falcifer accumulated more Cr than D. magna, but these differences were not significant (p>0.05). Almost no information is available about metal toxicity in freshwater copepods so the reported results are of high importance in order to detect good biomonitors of freshwater Cr-polluted environments.
