“…The concentrations of these elements in depot sludge, after multiplication with fresh to dry tissue mass ratio (1.42), were still manifold lower compared to regulations. In addition, based on the comparison with previously published concentrations of several metals (Cd, Cu, Fe, and Zn), depot sludge used in our study could be categorized as uncontaminated or weakly contaminated soil (Carpené et al, 2006). However, increased concentrations of ammonia, nitrate, phosphate, total nitrogen and phosphorus, as well as high total bacteria count were found in treated wastewater discharged from the same WWTP from which depot sludge used in this study was acquired (unpublished results).…”

“…Biosolids, such as active and depot sludge, are often used in agriculture as fertilizers, due to their ability to enhance growth of agricultural crops (Scheifler et al, 2003;Carpené et al, 2006;Braguglia et al, 2015). However, besides the obvious benefits of agricultural use of sludge, possible disadvantages should also be considered.…”

“…However, besides the obvious benefits of agricultural use of sludge, possible disadvantages should also be considered. As is well known, sludge can contain various organic, inorganic and microbiological contaminants, which could be transferred to soil or accumulated in crops, and consequently could have toxic effects on animal and human health (Scheifler et al, 2003;Carpené et al, 2006;Braguglia et al, 2015). Although the use of sewage sludge in agriculture is regulated by national and international directives (Minister of Environmental Protection, Physical…”

“…They can accumulate high levels of contaminants due to their feeding habits (Morgan and Morgan, 1998;Carpené et al, 2006;Hsu et al, 2006), as well as due to dermal exposure of their whole body (Lanno et al, 2004;Kamitani and Kaneko, 2007). The most commonly used earthworm species for biomonitoring is Eisenia fetida (Nahmani et al, 2007a), which is recommended for use in several international standard toxicity tests (OECD, 2004).…”

“…The specific aims of the study were: (1) to define the level of metal/metalloid contamination of depot sludge; (2) to establish a baseline for metal/metalloid elements in whole earthworm tissues, as well as for the first time in the soluble tissue fraction, based on the measured concentrations in non-exposed organisms; and (3) to study the patterns of metal/metalloid variability in earthworms after exposure to depot sludge. Commonly, only few selected elements are monitored in the earthworms, such as Cd, Cu, Fe, Pb, and Zn (Carpené et al, 2006;Kamitani and Kaneko, 2007;Suthar and Singh, 2009;Li et al, 2010;Giska et al, 2014). Only seldom studies extend on larger number of elements (Nahmani et al, 2007b;Nahmani et al, 2009;Nannoni et al, 2014).…”

Treated sewage sludge is commonly used in agriculture as fertilizer. It is, therefore, necessary to determine possible detrimental influences of sludge application on soil contamination and accumulation of contaminants in tissues of terrestrial animals, which in the long run could also have undesirable effects on humans. With that aim, the study was performed using earthworm Eisenia fetida as test organism and semi-solid depot sludge from wastewater treatment plant as exposure media. The concentrations of 26 metals/metalloids were determined in depot sludge, and their bioaccumulation was estimated in whole tissue of E. fetida, and for the first time in the soluble tissue fraction, which represents metal fraction available for metabolic requirements and toxic effects.Obtained results have revealed acceptable levels of several elements (Cd, Cr, Cu, Ni, Pb, Zn) in depot sludge, when compared to currently valid regulations, and only moderate accumulation of some elements (e.g. As, Ba, Cd, Co, Fe, Tl, V, and Zn) in earthworms, as a consequence of exposure to depot sludge. However, concentration increase after exposure to depot sludge was observed in E. fetida for several elements (Cd, Mo, and Zn), which were present in lower concentrations in the exposure mixtures than in soil. Contrary, concentration decrease was observed for Cs, Mn, and Rb, although they were present in higher concentrations in depot sludge than in soil. It was an indication of disturbance in metal homeostasis in earthworms, possibly caused by exposure to complex mixture of contaminants present in depot sludge. The cumulative effect of exposure to a number of various contaminants (inorganic, organic, microbiological and pharmaceutical), even if each of them was not present in very high concentrations, could have caused distress in earthworms exposed to depot sludge.

Across a large mountain area of the western Swiss Alps, we used occurrence data (presence‐only points) of bird species to find suitable modelling solutions and build reliable distribution maps to deal with biodiversity and conservation necessities of bird species at finer scales. We have performed a multi‐scale method of modelling, which uses distance, climatic, and focal variables at different scales (neighboring window sizes), to estimate the efficient scale of each environmental predictor and enhance our knowledge on how birds interact with their complex environment. To identify the best radius for each focal variable and the most efficient impact scale of each predictor, we have fitted univariate models per species. In the last step, the final set of variables were subsequently employed to build ensemble of small models (ESMs) at a fine spatial resolution of 100 m and generate species distribution maps as tools of conservation. We could build useful habitat suitability models for the three groups of species in the national red list. Our results indicate that, in general, the most important variables were in the group of bioclimatic variables including “Bio11” (Mean Temperature of Coldest Quarter), and “Bio 4” (Temperature Seasonality), then in the focal variables including “Forest”, “Orchard”, and “Agriculture area” as potential foraging, feeding and nesting sites. Our distribution maps are useful for identifying the most threatened species and their habitat and also for improving conservation effort to locate bird hotspots. It is a powerful strategy to improve the ecological understanding of the distribution of bird species in a dynamic heterogeneous environment.

Efforts have been made to evaluate the possible risks of metal bioaccumulation in composting earthworms during vermicomposting of hazardous wastes, e.g., sewage sludge. The sewage sludge was diluted by mixing cow dung in different proportions, and vermicomposted sludge as well as inoculated earthworms were analyzed for metal (Fe, Cu, Zn, Pb) contents. The sludge processed by worms showed a significant reduction in concentration of metals, Cu (29.4-51.6%), Fe (13.1-19.9%), Zn (15.2-25.8%), and Pb (4.6-46.9%), at the end. A considerable concentration of metals, total Cu (16.7-27.6 mg kg 21 ), total Fe (42.9-89.8 mg kg 21 ), total Zn (5.85-75.0 mg kg 21 ), and total Pb (1.79-12.4 mg kg 21 ), in composting earthworms was also recorded. The greater values of bioconcentration factors for metals suggested the possible risk of entering contaminants in higher food chains; since, earthworms are near to the terrestrial food chain, they can potentially mediate metal transfer from soil to a range of predators, including birds. Therefore, feasibility of vermitechnology in hazardous waste recycling needs close attention in respect to possible risk of environmental contamination. # 2008 Wiley Periodicals, Inc.
