“…The influence of hydrocarbons and heavy metals on nematode assemblages has been shown by many authors in both field and microcosm studies (e.g., Giere, 1979;Renaud-Mornant et al, 1981;Danovaro et al, 1995;Austen and Somerfield, 1997;Danovaro et al, 1999;Beyrem et al, 2007;Heininger et al, 2007;Boufahja et al, 2011a). As well as their direct effects on nematode assemblages, hydrocarbons also appear to influence nematodes indirectly through effects on sediments such as dissolved oxygen depletion and changes in sediment proprieties (Mahmoudi et al, 2005 and refs therein), while the accumulation of heavy metals in sediments may alter associated microbial communities which may influence the meiobenthos through alterations in food supply (Austen and McEvoy, 1997).…”

a b s t r a c tThe spatial distribution and structure of nematode assemblages in the area surrounding the harbour of Vado Ligure (Savona, NW Mediterranean) were studied in relation to the influence of natural and anthropogenic environmental factors. Stations were selected following an "anthropogenic gradient" from sites located near the city centre and its harbour to more pristine and distant sites. Sediment quality was determined by considering both sediment granulometric and chemical parameters (hydrocarbons, heavy metals, total organic matter, proteins, carbohydrates) as well as nematode abundance, diversity, life strategies, trophic structure and assemblage composition. A high correlation between environmental characteristics and the nematode response was found. On the basis of the comparison of these results, which identified three distinct sub-areas associated with different levels of environmental quality, a set of nematode indicator genera was selected for the future evaluation of quality status.

“…This maximal concentration was exceeded in the sediments taken from Calbe by approximately fivefold and at the sampling site Luppe even 34-fold. For a further assessment of possible effects caused by estrogenic compounds, in particular the 4-iso-nonylphenols, on sediment-dwelling organisms, a detailed analysis of, for example, the nematode community [41] at this sampling site should be performed. An analysis of the estrogenic potentials in corresponding surface waters was not performed.…”

Abstract-Sediments along the river Saale, one of the main tributaries of the river Elbe, were characterized with the yeast estrogen screen to elucidate possible sources of endocrine-disrupting compounds that might contribute to the downstream contamination of the river Elbe. At two sampling sites, elevated levels of estrogenic activity up to 55,000 ng ethinylestradiol equivalents per kilogram sediment dry weight were detected in the respective sediment extracts. Aliquots of the sediment extracts were analyzed for 4-nonylphenols and natural steroidal estrogens as possible candidates with an estrogenic potential. The maximal concentrations of 4-iso-nonylphenol and estrone were 115 mg/kg dry weight and 20 mg/kg dry weight at the sampling site Luppe, which showed in accordance the highest biological activity. Under consideration of compound concentration and compound specific estrogenic activity the 4-iso-nonylphenols contributed most to the observed estrogenic effect. A strong correlation between the measured estrogenic activity and the concentration of the sediment-associated 4-iso-nonylphenol underlines the relevance of this compound class as a xenoestrogen in the catchment area of the river Saale.

“…TA species found in this study are predators or mixotrophic (predator with algae symbiosis) in the microbial food web, and each species has a different diet (Gilbert et al, 2000). In soil, trophic groups of nematodes have been used for bioindication of pollution (Pen-Mouratov et al, 2008;Heininger et al, 2007). In the same way, trophic groups of TA living in bryophytes could be used in the bioindication of atmospheric pollution.…”
