Dietary intake of persistent organic pollutants and potential health risks via consumption of global aquatic products
Authors: Yu Huan-Yun , Guo Ying , Zeng Eddy Y. 
Published: August 2010

AbstractThe concentration levels of typical persistent organic pollutants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) including dioxin-like PCBs (DL-PCBs) and non–dioxin-like PCBs, organochlorine pesticides (OCPs), and polybrominated diphenyl ethers (PBDEs) in global aquatic products from major producing countries were summarized. Daily intakes of these compounds via consumption of various aquatic products for global consumers were also estimated based on available literature data. Risk assessment based upon existing criteria for OCPs and PBDEs shows that there is minimal risk to global consumers from consumption of aquatic products, with the exception of products from specific regions located around known heavy-point sources. Exposure to dioxins through consumption of aquatic products, excluding marine fish, is also in the range of the acceptable level, lower than 4 pg World Health Organization toxic equivalent (WHO-TEQ)/kg bw/d; however, dioxin intake via marine fish may cause hazards to human health, especially for Europeans. Regarding PCBs, there is cancer risk for global consumers via consumption of aquatic products, especially marine fish, based on cancer and noncancer hazard ratio assessment. Generally, European consumers have higher exposure levels of PCDD/Fs and DL-PCBs, while Americans and Asians have relatively higher exposure levels of OCPs and PCBs. In contrast, all global populations are found to have lower exposure levels of PBDEs, which may be attributed to its relatively shorter history of use compared with PCBs and OCPs. Finally, the estimated total amounts of PCBs, OCPs, and PBDEs stored in global aquatic products constitute only a small portion of the total amount that has been used, and the majority obviously occurs in other environmental media or even remains in commercial products.

Determination and occurrence of retinoic acids and their 4-oxo metabolites in Liaodong Bay, China, and its adjacent rivers
Authors: Wu Xiaoqin , Hu Jianying , Peng Hui , Dong Zhaomin 
Published: August 2010

Abstract
Retinoic acids (RAs) and their metabolites play an important role in abnormal morphological development and are speculated to be a possible cause for the increased rates of deformities in wild frog populations. In the current study, a method using ultra-performance liquid chromatography-electrospray ionization tandem mass spectrometry was developed for simultaneously analyzing all-trans-RA (at-RA), 13-cis-RA (13c-RA), 9-cis-RA (9c-RA), and their 4-oxo metabolites, all-trans-4-oxo-RA (at-4-oxo-RA), 13-cis-4-oxo-RA (13c-4-oxo-RA), and 9-cis-4-oxo-RA (9c-4-oxo-RA) in wastewaters and surface waters. Method detection limits were matrix dependent, ranging from 0.02 to 0.37 ng/L. The method was used to investigate the occurrence of RAs and 4-oxo-RAs in Liaodong Bay and its adjacent rivers. Of these six retinoids, at-RA, 13c-RA, at-4-oxo-RA, and 13c-4-oxo-RA were detected in river waters at detection frequencies of 100%, 92%, 48.6%, and 21.6%, and concentrations of 0.05 to 1.23 ng/L, less than 0.03 to 0.41 ng/L, less than 0.02 to 1.00 ng/L, and less than 0.06 to 0.81 ng/L, respectively. Retinoic acids were detected for the first time in the aquatic environment and were found to be more persistent than 4-oxo-RAs. The hazard quotient for mortality of frog embryos caused by induction by retinoids detected in the current study was then estimated, and the value was calculated to be 0.09. No retinoid was detected in seawaters. Environ. Toxicol. Chem. 2010;29:2491–2497. © 2010 SETAC
Developmental toxicity of selenium to Dolly Varden char (Salvelinus malma)
Authors: McDonald Blair G. , deBruyn Adrian M.H. , Elphick James R.F. , Davies Martin , Bustard David , Chapman Peter M. 
Published: August 2010

Abstract
Gametes were collected from Dolly Varden char (Salvelinus malma) from waterbodies in a region exposed to mining-related selenium (Se) releases in British Columbia, Canada. Fertilized eggs were incubated in a laboratory and deformities were assessed on newly-hatched alevins using a graduated severity index. No effects were observed on egg or alevin survival or larval weight across the studied exposure range of 5.4 to 66 mg/kg dry weight in egg. Length of some larvae was reduced at the highest egg Se concentrations and a clear residue–response relationship was observed for larval deformity. The egg concentration corresponding to a 10% increase in the frequency of deformity (EC10) was 54 mg/kg dry weight, which is substantially higher than reported for other cold-water fish species.

Ökologische Bedingungen der Erscheinung der Weißbuche in den Quercus frainetto‐Beständen im Westen der rumänischen Ebene
Authors: Marcu Gheorghe 
Published: August 2010

AbstractDie ökologischen Untersuchungen über die forstliche Vegetation der rumänischen Ebene zwischen Olt und Teleorman in einer vergleichenden Analyse der Verbreitung der Weißbuche (Carpinus betulus L.) und der Ungarischen Eiche (Quercus frainetto Ten.) in Abhängigkeit von den Standortsbedingungen ergaben für die beiden Arten:Die Verbreitungsgebiete der Weißbuche und der Ungarischen Eiche durchdringen sich in der erforschten Gegend, jedoch infolge ihrer verschiedenen Eigenschaften finden sich diese beiden Holzarten sehr selten in Mischbeständen.Die Weißbuche wächst besonders in den Auen der Flachland‐Forstzonen, auf Terrassen, auf höheren Geländen, wo keine Überflutungen stattfinden und wo der Grundwasserspiegel unter 1,5–3 m liegt, neben Stieleiche, Feldulme, Eschenarten, Linde, Feldahorn und Spitzahorn. Sie bevorzugt reiche, neutrale Böden verschiedener mineralogischer Struktur mit ausreichend Wasser.Die Ungarische Eiche hat ihr Vegetationsoptimum auf Hochebenen und besonnten Abhängen. In den Waldtypen der Hügelzone erscheint sie mit geringem Anteil, während sie in Auenwäldern nicht gedeiht. Sie benötigt als Bestandsbildner vorwiegend trockenen Untergrund, Tongesteine mit niedrigem Calciumcarbonatspiegel, auf denen sich dichte Böden bilden.Zur Bodenverbesserung und biologischen Entwässerung wird eine künstliche Durchdringung der Quercus frainetto‐Bestände mit Weißbuche angestrebt.Die Weißbuche und die Ungarische Eiche (Quercus frainetto Ten.) gesellen sich infolge der verschiedenen ökologischen Eigenschaften im Westen der Rumänischen Ebene wie auch im ganzen Verbreitungsgebiet dieser Holzarten ziemlich selten.
Phytosociological and Ecological Studies of Maktila Sector of Sidi‐Barrani I. Sociology of the Communities
Authors: Migahid A. M. , El‐Sharkawi H. M. , Batanouny K. H. , Shalaby A. F. 
Published: August 2010

AbstractPhytososiological study of this area is based on the analysis of vegetation in 110 stands, using the Zurich‐Montpellier technique. The informations about all the stands were collected together in one tableau in which the stands were arranged in associations, making use of the classification of characteristic species made by previous authors in other parts of the Mediterranean littoral of Egypt. Such synthesis has led to the recognition of six associations. One of these, namely, the Ammophiletum arenariae covers the coastal sand dunes. The other five are grouped together in one alliance, named Thymelaeion hirsutae, which covers the broader strip behind the dunes that extend many kilometers inland.

Die Bärentrauben‐Lärchenwälder im Charchiraa‐Gebirge (Mongolei)
Authors: Sommer M. S. 
Published: August 2010

AbstractIm Herbst 1995 wurden Untersuchungen zu Vegetation und Bodenverhältnissen sowie zu Physiognomie, Altersstruktur und Dynamik in Lärchenwäldern des Charchiraa‐Gebirges im Nordwesten der Mongolei durchgeführt. Dabei konnte eine Pflanzengesellschaft ausgegliedert werden, die nach der dominanten Pflanzenart „Bärentrauben‐Lärchenwald”︁ genannt wird. Sie wird als Subassoziation des Betulo rotundifoliae‐Laricetum HILBIG (1987) 1990 aufgefaßt. Bei den Böden handelt es sich um Paratschernoseme mit humosem, zum Teil auch anmoorigem Oberboden und meist mächtiger organischer Auflage. Die Böden sind basenhaltig, wobei der pH‐Wert mit steigender Tiefe zunimmt. Charakteristisch für die nur selten und kleinflächig vorkommenden Standorte ist ihre Lage in Hangbereichen mit nur geringer Hangneigung sowie ständige Wasserversorgung durch allmählich oberflächlich auftauenden Permafrostboden im Sommer mit Staunässe und einhergehender Bildung von kleinen Moorbereichen. Diagnostisch wichtige Arten sind Arctous alpina, Equisetum scirpoides, Carex microglochin, Trollius asiaticus, Claytonia ioanneana und das Moos Aulacomnium palustre. Die Wälder bestehen vorwiegend aus Bäumen der Altersklassen 180‐300 Jahre. Jungwuchs im Alter von 10–20 Jahren ist gering und physiognomisch nicht auffällig. Der Gesamtcharakter der Bestände ist daher weitständig und offen.

Beitrag zu einigen Araliaceae‐Blättern des Alttertiärs
Authors: Rüffle L. 
Published: August 2010

AbstractDie Verbreitung der Araliaceae im Alttertiär ist vor allem durch Samen belegt, die zumeist zu Schefflera J. R. & G. Forst, gestellt werden. Pollenfunde werden Brassaiopsis Decne. & Planch. zugerechnet. Die Bestimmung der häufigen handförmigen Blätter als Araliaceae erscheint in der älteren Literatur berechtigt (Saporta 1881). Hinzu kommen stark asymmetrische scharf gezähnte Einzelblätter mit unterschiedlichem Aussagewert. Viele von ihnen wurden trotz deutlicher Asymmetrie und starker Zähnung Myrica L. zugerechnet, soweit sie kürzer als 10 cm waren. In der vorliegenden Arbeit werden einige größere handförmige Blätter behandelt.

Framework for interpreting sediment quality triad data
Authors: Bay Steven M , Weisberg Stephen B 
Published: August 2010

Abstract
Integration of multiple lines of evidence (MLOE) data in a sediment quality triad assessment can be accomplished by means of numerous approaches, with most relying on some form of expert best professional judgment. Best professional judgment (BPJ) can be problematic in application to large data sets or in a regulatory setting where the assessment protocol needs to be transparent and consistently reproducible. We present a quantitative, objective framework for integrating the results of triad-based assessments and test its efficacy by applying it to 25 California sites and comparing the resulting classifications with those of 6 experts who were provided the same data. The framework is based on integrating the answers to 2 questions: 1) is there biological degradation, and 2) is chemical exposure high enough to potentially result in a biological response? The framework produced results that matched the median classifications of the experts better than did 5 of the 6 experts. Moreover, the framework was unbiased, with samples that differed from the median expert response evenly divided between those classified as more or less impacted. The framework was also evaluated by application to a set of sites from known degraded and reference areas, which the framework distinguished well. Although any framework needs to be flexible to supplemental data when they are available, the framework presented provides an objective means for using a triad-based approach in large-scale assessments for which relying on expert input for every sample is impractical.

A review of sediment quantity issues: Examples from the River Ebro and adjacent basins (Northeastern Spain)
Authors: Batalla Ramon J , Vericat Damià 
Published: August 2010

Abstract
Sediment flows naturally through the drainage network, from source areas to deposition zones. Sedimentary disequilibrium in rivers and coastlines is related to the imbalance within the fluvial system caused mostly by dams, instream mining, and changes in land use. This phenomenon is also responsible for ecological perturbations in rivers and streams. A broad need exists to establish comprehensive management strategies (soft measures) that would go beyond site-specific engineering practices (technical measures) typically taken to solve particular problems. Long-term programs are also required to monitor sediment transport in river basins, in order to assess the magnitude and variability of sediment transfer and potential deficits. This paper shows examples of rivers with important sediment disequilibrium in the Ebro and adjacent basins. These basins, like most in the Iberian Peninsula, experience sediment discontinuity in the catchment–river–coast system. Reservoir siltation is the main quantitative issue. Land use change and especially gravel mining downstream from dams accentuate the process. We also present and discuss recent developments on water and sediment management undertaken to improve the morphosedimentary dynamics of rivers.
