Methane fluxes were measured, using closed chambers, in the Crater of Solfatara volcano, Campi Flegrei (Southern Italy), along eight transects covering areas of the crater presenting different landscape physiognomies. These included open bare areas, presenting high geothermal fluxes, and areas covered by vegetation, which developed along a gradient from the central open area outwards, in the form of maquis, grassland and woodland. Methane fluxes decreased logarithmically (from 150 to -4.5 mg CH4 m(-2)day(-1)) going from the central part of the crater (fangaia) to the forested edges, similarly to the CO2 fluxes (from 1500 g CO2 m(-2)day(-1) in the centre of the crater to almost zero flux in the woodlands). In areas characterized by high emissions, soil presented elevated temperature (up to 70 degrees C at 0-10 cm depth) and extremely low pH (down to 1.8). Conversely, in woodland areas pH was higher (between 3.7 and 5.1) and soil temperature close to air values. Soil (0-10 cm) was sampled, in two different occasions, along the eight transects, and was tested for methane oxidation capacity in laboratory. Areas covered by vegetation mostly consumed CH4 in the following order woodland>macchia>grassland. Methanotrophic activity was also measured in soil from the open bare area. Oxidation rates were comparable to those measured in the plant covered areas and were significantly correlated with field CH4 emissions. The biological mechanism of uptake was demonstrated by the absence of activity in autoclaved replicates. Thus results suggest the existence of a population of micro-organisms adapted to this extreme environment, which are able to oxidize CH4 and whose activity could be stimulated and supported by elevated concentrations of CH4. 相似文献

Contamination by microscopic fungi and mycotoxins in different bee pollen samples, which were stored under three different ways of storing as freezing, drying and UV radiation, was investigated. During spring 2009, 45 samples of bee-collected pollen were gathered from beekeepers who placed their bee colonies on monocultures of sunflower, rape and poppy fields within their flying distance. Bee pollen was collected from bees’ legs by special devices placed at the entrance to hives. Samples were examined for the concentration and identification of microscopic fungi able to grow on Malt and Czapek-Dox agar and mycotoxins content [deoxynivalenol (DON), T-2 toxin (T-2), zearalenone (ZON) and total aflatoxins (AFL), fumonisins (FUM), ochratoxins (OTA)] by direct competitive enzyme-linked immunosorbent assays (ELISA). The total number of microscopic fungi in this study ranged from 2.98 ± 0.02 in frozen sunflower bee pollen to 4.06 ± 0.10 log cfu.g?1 in sunflower bee pollen after UV radiation. In this study, 449 isolates belonging to 21 fungal species representing 9 genera were found in 45 samples of bee pollen. The total isolates were detected in frozen poppy pollen 29, rape pollen 40, sunflower pollen 80, in dried poppy pollen 12, rape pollen 36, sunflower 78, in poppy pollen after UV radiation treatment 54, rape 59 and sunflower 58. The most frequent isolates of microscopic fungi found in bee pollen samples of all prevalent species were Mucor mucedo (49 isolates), Alternaria alternata (40 isolates), Mucor hiemalis (40 isolates), Aspergillus fumigatus (33 isolates) and Cladosporium cladosporioides (31 isolates). The most frequently found isolates were detected in sunflower bee pollen frozen (80 isolates) and the lowest number of isolates was observed in poppy bee pollen dried (12 isolates). The most prevalent mycotoxin of poppy bee pollen was ZON (361.55 ± 0.26 μg.kg?1), in rape bee pollen T-2 toxin (265.40 ± 0.18 μg.kg?1) and in sunflower bee pollen T-2 toxin (364.72 ± 0.13 μg.kg?1) in all cases in frozen samples. 相似文献

Goal, Scope and Background One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking
water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle
waste water into high quality water. It seems timely to discuss alternative water remediation technologies that are fit for
industrial as well as less developed countries to ensure a high quality of drinking water throughout Europe.
Main Features The present paper discusses a range of phytoremediation technologies to be applied in a modular approach to integrate and
improve the performance of existing wastewater treatment, especially towards the emerging micro pollutants, i.e. organic chemicals
and pharmaceuticals. This topic is of global relevance for the EU.
Results Existing technologies for waste water treatment do not sufficiently address increasing pollution situation, especially with
the growing use of organic pollutants in the private household and health sector. Although some crude chemical approaches
exist, such as advanced oxidation steps, most waste water treatment plants will not be able to adopt them. The same is true
for membrane technologies.
Discussion Incredible progress has been made during recent years, thus providing us with membranes of longevity and stability and, at
the same time, high filtration capacity. However, these systems are expensive and delicate in operation, so that the majority
of communities will not be able to afford them. Combinations of different phytoremediation technologies seem to be most promising
to solve this burning problem.
Conclusions To quantify the occurrence and the distribution of micropollutants, to evaluate their effects, and to prevent them from passing
through wastewater collection and treatment systems into rivers, lakes and ground water bodies represents an urgent task for
applied environmental sciences in the coming years.
Recommendations Public acceptance of green technologies is generally higher than that of industrial processes. The EU should stimulate research
to upgrade existing waste water treatment by implementing phytoremediation modules and demonstrating their reliability to
the public. 相似文献
