A diatom quality index to assess diatom community impairment in the nearshore wetlands of the Laurentian Great Lakes was developed from a diatom-based total phosphorus (TP) weighted average inference model. The index is calculated with a weighted average equation using species optima standardized to a 1–10 scale and species tolerance standardized to a 1–3 scale. Multiple regression analysis revealed a moderate fit (R 2 = 0.63) between site scores of the selected index and GIS derived watershed characteristics (agriculture, soils, and industrial facilities). These index scores more closely fit watershed characteristics than the diatom inferred TP (R 2 = 0.59). In a regression tree analysis, soil permeability separated higher index scores from lower scores identifying this variable as an important interaction factor in the analysis. The diatom quality index can be a powerful tool for analyzing habitat quality in the Great Lakes and can communicate the link between quantifiable diatom assemblage response with watershed-level disturbance.

Editors' note: Research Notes is a new section now being added to the EBI format. Its purpose is to provide a forum for the publication of short research communications that provide important information but, due to their restricted focus, are not formatted in the manner of full research papers. All papers published under this heading will be peer reviewed. In order to follow the effects of pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorobenzenes (PCBs), and dioxins upon the European eel, we have developed an assay that quantifies hepatic cytochrome P4501A1 (CYP1A1) mRNA levels using real-time reverse transcription polymerase chain reaction (real-time RT-PCR). In this study, European eels were exposed to a diesel water soluble fraction (DWSF) in order to mimic environmental exposure to a mixture of organic pollutants. CYP1A1 mRNA levels were measured after 3, 6, 12, 24, 48, 72 and 156 h of exposure. The 7-ethoxyresorufin O-deethylase (EROD) activity was measured in parallel to confir...

Biomarker responses at the histological level to xenobiotics are gaining a priority research interest. The 96h LC50 of copper sulfate to Esomus danricus is found to be 5.5 mg/L and its toxic effects on fish gills are critically examined in situ. Gills (pair III) of fish exposed to 5.5 mg/L and 0.55 mg/L of copper sulfate and control without toxicant were placed in normal saline medium and, after rinsing, placed on a glass slide and observed under a Polyvar, Reichert-Jung light microscope attached to Ethovision-version 2.3 (Noldus Information Technology, Netherlands) through a Sony CCD IRIS camera (Model No: SSC-M370CE). Damage to secondary gill lamellae with loss of shape, necrosis, clubbing and fusion, shaft breakage, atrophy, curvature of tips, thick mucous sheathing and degeneration of rakers are observed in fish exposed to 5.5 mg/L of copper sulfate. Primary and secondary gill lamellae are affected with loss of original shape, loss of alignment in rakers with hyper secretion of mucous in fish exposed ...

Editors' Note: At the 14th International Conference on Environmental Bioindicators (14th ICEBI) held in Linthicum Heights, Maryland, USA on 24–26 April 2006, the Conference Chairs and Program Committee initiated the Roundtable Discussion Groups as a regular feature of this and future conferences. The Discussions are designed to generate focused debate around key topic areas, led by academic, government and industry experts, and are structured to produce definitive papers for peer review and publication in EBI's first-quarter issue of each publication year, albeit this year the papers will be published over the first two issues of 2007. The three Roundtables of the 14th ICEBI posed questions revolving around the chosen topic areas of Mercury Bioindicators, Marine Ecosystem-level Indicators, and Regulatory and Policy Uses of Bioindicators, and moved from “what we know” to “where we need to go” and “what are the policy implications from our discussions and conclusions.” The following paper on coral reef indi...

Two novel biomarker of response assays were developed and compared for use with bivalves. Bivalve mollusks are often used as bioindicators to monitor contaminant body burdens and are employed globally in pollution monitoring and as sentinels of environmental quality. The prevalence of proliferating cells in tissues of the eastern oyster, Crassostrea virginica, (n = 10) was investigated by using immunohistochemical staining of proliferating cell nuclear antigen (PCNA) and by flow cytometric analysis of DNA in cell cycle phases. The PCNA protein is highly conserved and central to DNA synthesis in dividing cells. This protein was detected by using a commercial antibody in the histological staining of gills, mantle, digestive gland, stomach, and labial palps. Cells obtained from these same organs and from the hearts of the oysters were used for flow cytometry (FCM). The proportions of nuclei in the S plus G2/M and G2/M fractions were compared with percentages of PCNA-positive cells scored through microscopy. ...

Organisms are continuously exposed to a great variety of xenobiotics via food and environment. Evolution has equipped the body with a plethora of protecting systems to defend itself against the potentially harmful effects of these compounds. One of the important defense mechanisms include the active extrusion of xenobiotics by commonly shared transport proteins, mainly located in kidney, liver and intestine. An attempt has been made to understand the structural and functional properties of organic anion transporters (OAT1, OAT2, OAT3) and organic cation transporters (OCTN1, OCTN2, OCT1, OCT2, OCT3). These transporters share a predicted 12-transmembrane domain (TMD) structure with a large extracellular loop between TMD1 and TMD2, carrying potential N-glycosylation sites. Conserved amino acid motifs revealed a relationship to the sugar transporter family within the major facilitator superfamily. Following heterologous expression, most OATs transported the model anion p-aminohippurate (PAH). OAT1, but not OA...

The concentrations of Cd, Cu, Fe, Pb and Zn were measured in holothuroids Holothuria tubulosa collected during different seasons and at several depths in three N W Mediterranean Posidonia oceanica meadows (Calvi, Corsica; Ischia, Italy; Marseille, France). Metals were found to be selectively distributed among the holothuroid body compartments (i.e. body wall, gut, and haemal system). Among the sources of variation taken into account, the major part of the variability observed in metal concentrations was associated to the body compartment factor, then to the seasonal one and, finally, to the geographical and bathymetric factors. Our results suggest that, if one uses H. tubulosa as a bioindicator species for surveying and monitoring metal contamination in the Mediterranean P. oceanica meadows, attention should be paid to compare only concentrations measured in the same body compartments of individuals collected during the same period of the year. Body compartments that should be preferably considered for me...

Objective. The effect of cadmium exposure on serum amylase activity has been monitored in cadmium plating workers of Bangalore City (India).Methods. Fifty subjects using cadmium during electroplating formed the study group. An equal number of age–sex matched subjects working in administrative sections formed the control group. Urinary cadmium levels were determined by using a flameless atomic absorption spectrophotometer. Serum amylase activity was determined by using spectrophotometric method. Results. A significant increase of urine cadmium and serum amylase activity was noted in the subjects of the study group as compared with the subjects in the control group. The level of serum amylase activity was positively and significantly associated with cadmium levels in urine. Multiple regression analysis was used to assess the effect of cadmium exposure on serum amylase activity. The analysis showed that the study subjects who had urine cadmium levels greater than 5-μg/ g of creatinine and cadmium exposure we...
