A new scheme for biomonitoring heavy metal concentrations in semi-natural wetlands

Designing a reliable leak bio-detection system for natural gas pipelines

“…The decomposition/recomposition module proposed herein offers the benefit of greatly reducing the amount of effort required in the knowledge engineering task. The drawback of applying this scheme, however, is that if raw low-level data is used, due to its representational sparseness, it is generally necessary to collect a greater population sample in order to construct a case base with adequate coverage [46]. Alternatively, human experts, as employed herein for running the multicriteria analysis selections, or even automated induction, clustering or other techniques can be used to construct a more restricted description space that carries the most critical to the decisionmaker case information; certainly there exists a tradeoff in the extra effort required to construct these representations, an effort that should be repeated whenever it is desired to expand the role of the system.…”

“…In principle, the high selectivity of the device, presented inherently by the bioelement that is tailored-made to meet the specific analyte(s), excludes most interference problems and matrix effects. Furthermore, the versatility of this technology allows for experimenting with numerous combinations of arrayed bioelements and transducers as micro-detectors in order to detect multi-analyte levels and exclude interference and cross-reactivity; in theory, and to certain extent has been proven in practice [45,46], any bioelement can be coupled with any transducer, allowing for in-built device characteristics to meet any specification requirements or restrictions. Biosensors are worldwide considered as a niche technology in the environmental market, since they afford the desired detector capabilities at low cost, provided they have been properly designed/developed/customized/utilized and rationally placed/networked/maintained/replaced by the aid of operational research techniques [47][48][49].…”

“…This validation approach has been utilized successfully by the authors to a number of environmental systems, including underground mine fields [184], landfills [185], oil refineries [191], forestrated areas [45,192] and wetlands [46]. These projects addressed multi-elemental monitoring in both phases, the gas and the liquid, through a regional network around a pollution source in the form of a local area network (LAN), with on-line data collection and mining, as regards biosensoring.…”

Estimation of plant sampling uncertainty: an example based on chemical analysis of moss samples

“…Among the wide and spread group of organisms, some moss species, e.g., Pleurozium schreberi , Hylocomium splendens , Hypnum cupressiforme , and Pseudoscleropodium purum have successfully been used as bioindicators of trace elements (Kaasik and Liiv 2007; Batzias and Siontorou 2008; Dragović and Mihailović 2009; González-Miqueo et al 2010; Kłos et al 2011; Mariet et al 2011) including rare earth elements (Chiarenzelli et al 2001; Dołęgowska and Migaszewski 2013), organic pollutants (Chiarenzelli et al 2001; Orliński 2002; Ares et al 2009; Foan et al 2010; Dołęgowska and Migaszewski 2011), and isotopes (Wadleigh 2003; Liu et al 2008; Xiao et al 2010; Migaszewski et al 2010; Liu et al 2011; Castorina and Masi 2015). …”

Bioaccumulation of trace elements in different tissues of three commonly available fish species regarding their gender, gonadosomatic index, and condition factor in a wetland ecosystem

“…They can decline water and sediments quality and may adversely affect fish health and other biological attributes like taxonomic richness, trophic structure, and health of individual organisms will change (Fernandes et al 2007;Batzias and Siontorou 2008). They can also form a major hazard because of their toxicity, persistence, and bioaccumulation in the food chains (Feng Li et al 2008;Sekhavatjou et al 2010Sekhavatjou et al , 2011Murugesan et al 2008;Taghinia Hejabi et al 2010).…”
