“…In the Acadian province, metal ESBs could not be calculated, but no ER-Ms were exceeded for any metal, indicating that effects were not probable. This lack of correspondence between ERMQ and ESBs has been seen previously [36]. Burgess et al [36] suggested that the accuracy of the different approaches be assessed via sediment toxicity testing.…”

“…This lack of correspondence between ERMQ and ESBs has been seen previously [36]. Burgess et al [36] suggested that the accuracy of the different approaches be assessed via sediment toxicity testing. In the present study, toxicity testing indicated that amphipod survival was always high, with no biologically significant differences seen, more closely matching the ESB predictions and the direct examination of ER-Ls and ER-Ms.…”

Eutrophication (i.e., nutrient enrichment, organic enrichment, and oxygen depletion) is one of the most common sources of impairment in Clean Water Act 303(d)-listed waters in the United States. Although eutrophication can eventually cause adverse effects to the benthos, it may be difficult to diagnose. Sediment organic carbon (OC) content has been used as an indicator of enrichment in sediments, but the amount of surface area available for carbon adsorption must be considered. We investigated the utility of the relationship between OC and sediment grain size as an indicator of eutrophication. Data from the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program was used to test this relationship. However, anthropogenic contaminants are also capable of causing adverse effects to the benthos and often co-occur with elevated levels of OC. Contaminant analysis and toxicity tests were not consistently related to enrichment status as defined by relationship between total OC and grain size. Although variability in response occurred, reflecting the variance in the water column factors (dissolved oxygen, chlorophyll a, and nutrients) and limited sample sizes, the data supported the hypothesis that sites designated as enriched were eutrophied. Dissolved oxygen levels were reduced at enriched sites, whereas chlorophyll a and nutrients were higher at enriched sites. This suggests that the relationship of OC to grain size can be used as a screening tool to diagnose eutrophication.

“…Sevastopol Bay (8.3 km 2 ) was divided into 3 parts: inner, central, and outer, with conspicuously different environmental parameters such as depth, grain-size composition, pH, Eh, O 2 concentration in near-bottom layers, and the industrial pollution level of bottom sediments with trace metals and organic pollutants such as PCBs, PAHs, and pesticides [38]. Such spatial division of the bay bottom area was based on the earlier obtained results on the assessment of key abiotic factors impact on the diatom taxocene structure in different part of Sevastopol Bay [13].…”

Benthic diatoms species richness was analyzed based on 93 samples collected at 8 areas of Crimea (Black Sea) on sandy/muddy bottoms within depth range 6-48 m. Totally 433 species were found. Expected species richness exp was estimated by application of Jack-knife -1 and -2, Chao-2, and Karakassis-∞ estimators. Magnitude of exp , resulted from ∞ , displayed the most similar values to the observed species number ( obs ). Overestimation of obs (10-13%) occurred for small number of samples (<12), and slight underestimation (3-5%) occurred when sample numbers exceeded 40-43. The other estimators gave large overestimated results (Chao-from 21 to 70% higher than obs , Jack-knife-23-58%). The relationship between number of samples (X) and number of observed species (Y) was calculated considering all 93 samples: = 79.01 ln( ) + 34.95. Accordingly, not less than 10 samples are required for disclosing about 50% of the total species richness (433); to detect 80% (347 species) not less than 46 samples should be considered. Different configurations of ∞ method were applied to optimize its performance. The most precise results can be achieved when the calculation of the exp is based on sequences of randomized samples with sampling lags of 10 to 15.

“…The resulting array of evidence refers mainly to coastal zones of cities, the localities receiving river inflow and to some close-to-norm inshore seawater areas and discloses background contamination levels. Measurements were performed in the upper and nearbottom seawater layers in the relatively shallow sea and in standard hydrological horizons in the pelagic zone (Romankevich and Aibulatov, 2004;BSC, 1998;Korshenko et al, 2008Korshenko et al, , 2009Zonn et al, 2008;Burgess et al, 2009). These data do not cover hydrological structure of the studied seawater areas and therefore are of little use to hydrobiologists.…”

For the first time the integral scene of the toxicological field in the northern Black Sea as it was in the 1990s, with characteristic seasonal and spatial variations, was obtained by means of the integral indices. Priority pollutants during the investigation time were iron, chrome and copper, the registered concentrations of which exceeded maximum allowable concentrations (MAC). In the surface micro layer of the sea total petroleum hydrocarbons and chlorine organic compounds (PCB, HCCH and DDT and its products) were also found in quantities exceeding MAC.Most probably, the spring (March, May) peak of pollution observed in the pelagic zone developed as a result of the spring flood. In July, the relative well-being of the sea was owing to that spring-summer phase of plankton succession completed in a mass descent of dead plankton to the sea floor that, together with intensive sedimentation of pollutants by suspended matter, favored natural purification.
