The influence of environmental conditions on the lifespan of mosses under long-term active biomonitoring
2021
Abstract Biomonitoring with living organisms is most often used in order to gather quick information about environmental quality – for example the level of heavy metals polluting the air. Experiments are not often performed when the bioindicator is exposed to pollutants over the long time (6 months and more) because this period required to obtain credible results and the risk not yet studied of physiological changes and of degeneration of the living material which would undoubtedly affect the biomonitoring results. The aim of study was to evaluate the physiological condition of Pleurozium schreberi moss species subjected to continuous exposure for a year, using the moss-bag method, under va…
High activity mesoporous copper doped cerium oxide catalysts for the total oxidation of polyaromatic hydrocarbon pollutants
2012
The doping of mesoporous ceria with copper significantly enhances activity for naphthalene total oxidation, the enhanced performance is controlled by the increased concentration of surface oxygen defects.
Geographical and ecological outline of metal(loid) accumulating plants in Italian vascular flora
2018
The decontamination of heavy metal polluted soils is one of the major challenges that our industrialized world has to face. Remediation technologies are being developed and employed in order to reduce the potential hazards of metal and metalloid contamination. Plants capable of uptaking metals and metalloids in their tissues can be an effective tool to remove such pollutants from contaminated soils. The use of this plant-driven process (Phytoremediation) requires the knowledge of the right phytoextractors to use when facing different types of contamination. The aim of this paper is to provide an inventory of phytoextractors that can be used in Phytoremediation procedures in Italy. The check…
Leaf Biosorbents for the Removal of Heavy Metals
2018
The presence of heavy metals in waters is a global concern. Among various remediation technologies, biosorption is an attractive and promising process since in many cases, it is fast, selective, and highly efficient. Other advantages, such as applicability for various types of pollutants, simplicity, low cost, ease of operation, and the potential reusability of the adsorbents, make it beneficial. Nowadays, more and more green materials, raw or modified, are inclined to be explored instead of conventional adsorbents, within concept of Green Chemistry. This review focuses on the use of leaves-based biosorbents in raw or modified forms to sequestrate heavy metals from waters and wastewaters.
Recent advances on portable sensing and biosensing assays applied for detection of main chemical and biological pollutant agents in water samples: A …
2021
Abstract The quality analysis of water, pharmaceutical and environmental compounds is a basic subject for human health. The presence of low-quality drugs, biological toxins and chemical compounds in water or forbidden additives in the nourishments lead to irreversible problems in human health. Hence, multiple analytical approaches have been presented for investigating the quality of environmental, pharmaceutical, and food compounds and monitoring the detection of toxic compounds and pollutants in water. Sensing tools based on analytical strategies are required for identifying and quantifying the different pollutants including biological and chemical contaminants in water samples. Among diff…
THE IMPACT OF WARFARE ON THE SOIL ENVIRONMENT
2013
Abstract One of the most dramatic ways humans can affect soil properties is through the performance of military activities. Warfare-induced disturbances to soil are basically of three types – physical, chemical, and biological – and are aimed at causing direct problems to enemies or, more often, are indirect, undesired ramifications. Physical disturbances to soil include sealing due to building of defensive infrastructures, excavation of trenches or tunnels, compaction by traffic of machinery and troops, or cratering by bombs. Chemical disturbances consist of the input of pollutants such as oil, heavy metals, nitroaromatic explosives, organophosphorus nerve agents, dioxins from herbicides, …
Soil Heavy Metals Patterns in the Torino Olympic Winter Games Venue (E.U.)
2008
International audience; The city of Torino (45°N, 7°E NW Italy) has a long history of heavy industry. Additional sources of potential pollutants originate from transport such as car emissions. We selected an area potentially at high risk of contamination: it is sandwiched between roads, the circular Turin highway and the motorway which connects to France, and a landfill where special and hazardous solid wastes from industry are disposed of. Our main aim was i) to discriminate between these sources of heavy metals (HM) and ii) to assess a simplified HM transfer scenario. We started with air diffusion models (inputs were meteo and chemistry of the particulate), then we described topsoils (12 …
