“…However, grazers influence the system not to the extent shredders do. Also, the results show a clear increase in element fixation along with only low remobilization potential contrasting predicted effects on metal/metalloid fixation/remobilization mentioned before (Schaller et al, 2011) (Fig. 4).…”

“…Nonetheless, invertebrate grazers activity during aquatic litter decomposition leads to a metal/metalloid fixation into leaf litter as part of sediment organic matter rather than to an enhanced mobilization into water. In conclusion, the effect of invertebrate grazers on metal/metalloid fixation/remobilization contrasts in parts former assessments (Schaller et al, 2011) revealing the facility of metal/metalloid fixation.…”

“…These invertebrates literally graze on the organic structures and thereby harvesting biofilm. An effect of invertebrate grazers on metal/metalloid accumulation/remobilization during aquatic litter decomposition was postulated by Schaller et al (2011) to be an increased remobilization, but has not been validated since then.…”

“…However, several studies have reported that addition of AC may have negative impacts on the habitat quality of the benthic organisms, reducing their activity (Janssen and Beckingham 2013;Kupryianchyk et al 2013). On the other hand, many invertebrate species associated with metals and metalloids polluted sediments in aquatic systems and some of them accumulated metals through diet (Geffard et al 2010;King et al 2006;Schaller et al 2011) Therefore, addition of AC and other sorbents to sediment may affect the metal accumulation in organisms. Shen et al (2012) reported that BSAF values for polycyclic aromatic hydrocarbons (PAHs) were elevated when MWNT-2 addition to sediment was greater than 1.5 %.…”

Adding activated carbon (AC) to sediment has been proposed as an in situ sediment remediation technique. To date, it is not clear whether this technique is effective in the treatment of heavy metal-contaminated sediment in the presence of bioturbators. In the present study, we compare the ability of granular-activated carbon (GAC) and powderactivated carbon (PAC) to reduce Cu, Zn, and Pb pore water concentrations at environmentally relevant concentrations in the absence and presence of Chironomid larvae. Compared to untreated sediment, PAC and GAC addition in the absence of Chironomid larvae resulted in reductions of free Cu concentrations of 78 and 66 % just below the sediment-water interface after 28 days, respectively. While for Pb and Zn these concentration reductions were only 40 and 38, 19 and 25 %, respectively. The presence of Chironomid larvae in untreated, and GAC sediment generally increased the free heavy metals concentrations in pore water, especially in the deeper layers. In comparison with untreated sediment, the coexistence of AC enhanced the accumulation of heavy metals, especially for PAC. This increased bioaccumulation may decrease the survival of Chironomid larvae. The result indicated that ACs may not be suitable for the remediation of heavy metalcontaminated sediments.

“…A specific oligochaete, Tubifex tubifex, have been the focus of systematic (Beauchamp et al 2001;Sjölin et al 2005;Crottini et al 2008;Doumen 2010), ecological (Coto and Szostak 1995;Sturmbauer et al 1999;Schaller et al 2011), toxicological (Bouché et al 2000;Rathore and Khangarot 2002;Maestre et al 2009;O'Connor et al 2012) and parasitological (Baxa et al 2008) studies. This worm is one of the most abundant oligochaete present in the European springs, where it plays a pivotal role in the detritus food chain.…”

The cosmopolitan freshwater oligochaete Tubifex tubifex is an important health indicator of the aquatic environment. Water pollutants can affect the intraspecific biodiversity grade of local Tubifex colonies. A genetic profile of specimens collected in an environment with reduced anthropic presence is particularly important to define genetic variability in unperturbed Tubifex populations, and it is still missing in the international literature. Therefore, it has been performed the analysis of lineage composition in a T. tubifex colony from high mountain spring ponds in Central Italy, characterized by a very low concentration of heavy metals. The sampling was performed during spring 2010 and 2011, in the Sett'acque valley (1,900 m above mean sea level), within the township of Lucoli. Data presented in this work depicted a peculiar composition of the population, characterized by a reduced complexity compared to other urban environments, and with no specimens belonging to the lineage I, largely described in many European populations. Interestingly, lineage 2e, previously discovered only in a natural reserve, results to be the most common lineage in this population. Considerations on environmental health and genetic evolution are discussed.
