“…The concentration of some potentially toxic elements (PTEs) (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn)) was analyzed in pore water of sediment, total sediment and SEM by inductively coupled plasmamass spectrometry (ICP-MS) (Roig et al, 2013). Blanks, controls and certified standard materials (Loamy clay soil, Resource Technology Corporation US, CRM 052) were used for quality control/quality assurance (QC/QA).The recovery percentage of the reference material ranged 71-95%.…”

“…Since the WFD implementation, some studies have observed that biological status is not always in coherence with physicochemical status (López-Doval et al, 2012;López-Serna et al, 2012;Roig et al, 2013). This trend may be explained by adaptation mechanisms of aquatic organisms under chronic chemical exposure or regional specificities of the communities that cause high tolerance under extreme conditions (Moss, 2007;Hering et al, 2010).…”

“…However, extrapolation of the results obtained from single species test batteries to ecosystems may be limited, and multiple tests at different trophic levels are needed for meaningful results (Ahlf et al, 2002;Allan et al, 2006;Schmitt-Jansen et al, 2008;Blasco and Picó, 2009). Since the eighties some authors have suggested the importance of integrated approaches combining ecological, chemical and ecotoxicological tools as a challenging task in environmental risk assessment (Long and Chapman, 1985;Chapman et al, 1997;Ahlf et al, 2002;SchmittJansen et al, 2008;Blasco and Picó, 2009;Roig et al, 2013). One example of these integrated evaluation tools is the sediment quality triad (SQT), that is based on combination of chemical analyses, experimental laboratory toxicity tests and field observations of sediments in marine or freshwater ecosystems (Long and Chapman, 1985;Chapman et al, 1997).…”

Due to the fact that chemical water analyses usually give punctual information, present high variability, and acute ecotoxicity of flowing water is sometimes non-detected due to the dilution factor (Allan et al, 2006;Roig et al, 2011Roig et al, , 2013; this study focuses on the sediment matrix. Sediment is able to integrate stream pollution for a long time, often presents higher pollutant concentrations than water and may actually act as both sink and source of contaminants for the water column (Voutsinou-Taliadouri and Varnavas, 1995;Roig et al, 2011Roig et al, , 2013.…”

This study is was designed to assess the ecological risk associated with chemical pollution caused by heavy metals and PAHs on the basis of their ecotoxicological properties in sediments collected from the Rzeszów dam reservoir (Poland). The sediment samples were collected from three sampling stations: S1—inlet, backwater station, S2—middle of reservoir, S3 outlet, near the dam. The sediments’ toxicity was evaluated using a battery of bioassays (Phytotoxkit, Phytotestkit, Ostracodtoxkit F, and Microtox). The highest content of metals (120.5 mg Zn; 22.65 mg Pb; 8.20 mg Cd ∙ kg−1 dw) and all PAHs (∑9361 μg ∙ kg−1 dw) in sediments was found at station S1. The lowest content of metals (86.72 mg Zn; 18.07 mg Cu; 17.20 mg Pb; 3.62 mg Cu; 28.78 mg Ni; 30.52 mg Cr ∙ kg−1 dw) and PAHs (∑4390 μg ∙ kg−1 dw) was found in the sediment from station S2. The ecological risk assessment of the six metals and eight PAHs revealed a high potential toxicity in sediments from stations S1 (PECq = 0.69) and S3 (PECq = 0.56) and a low potential toxicity in sediments from station S2 (PECq = 0.38). The studies also showed the actual toxicity of sediments for the test organisms. The sediment pore water was least toxic compared to the whole sediment: solid phases > whole sediment > pore water. The most sensitive organism for metals and PAHs in bottom sediments was Lepidium sativum, and in pore water—Sorghum saccharatum. The concentration of metals and PAHs in bottom sediments generally did not affect the toxicity for other organisms. Clay content and organic C content are likely to be important factors, which control heavy metal and PAH concentrations in the sediments. Data analysis by PCA found the same origin of metals as well as PAHs—mainly anthropogenic sources. The obtained information demonstrated the need to integrate ecotoxicological and chemical methods for an appropriate ecological risk assessment.

The importance of drying and grinding samples for determining mobile chromium fractions in polluted river sediments

A possible impact of sample preparation on the chemical fractionation results is generally underestimated in studies of forms of occurrence of heavy metals in river sediments. Our analysis of the recently published results of sequential extraction of chromium has revealed the effect of sample grinding on the result of determination of mobile chromium fractions in river sediments. This observation has been experimentally verified along with the analysation of potential effect of river sediment drying conditions on chromium distribution pattern. The studies were carried out on river sediments polluted with tannery effluents (Cr, 29.2–233 mg/kg). The determined content of chromium bound to carbonates in powdered samples was 2 to 7 times higher than those in raw river sediment samples. It was shown that the main reason was the different kinetic characteristics of chromium leaching in these sediments. Using the shrinking core model, it was found that diffusion through the “ash layer” was the rate-controlling step during the extraction of the carbonate fraction of chromium. It has been additionally confirmed that common air drying of sediment samples does not affect the results of chemical fractionation of chromium. The results of our studies are also vital for the assessment of environmental risk posed by river sediments polluted with heavy metals. In the case of sediment samples used in this study, powdering changed the risk category (RAC) from low risk to high risk . Hence, in order to achieve a realistic assessment of chromium mobility and environmental risk, it is advisable to use raw samples, despite their poorer homogeneity, and thus, lower precision of chemical fractionation results.
