We examined the flow of mercury (Hg) from benthic invertebrates to fishes in lakes with contrasting fish community structure. The study was carried out in two whole lakes in southcentral Ontario in 1992. Both were remote from direct sources of contamination and were chosen because of their physical and chemical similarities. Although the fish communities in the two lakes were qualitatively similar, the total number of fishes in Ranger Lake was an order of magnitude smaller than that in Mouse Lake. As a result of the lower net predation from benthivorous fishes, documented in earlier studies, Ranger Lake benthic invertebrate populations were significantly higher. However, benthic invertebrate taxa in Mouse Lake were generally larger and had higher Hg concentrations. This was partly attributed to the stunted growth of Mouse Lake fishes, which did not allow them to prey on larger benthos as a result of gape limitations. Despite the lower Hg concentrations in Ranger Lake benthos, total benthic invertebrate Hg pools were higher in this lake as a result of its higher total benthic invertebrate biomass. However, the transfer of total Hg from benthic invertebrates to fishes was higher in Mouse Lake due to the higher consumption rates of benthivorous fishes.

Combined Sewer

Abstract Urban wet-weather sources of pollution such as Stormwater and combined sewer overflows (CSOs) can contribute significantly to the contamination of receiving waters, particularly in sediment depositional areas near outfalls. Analyses of sediment chemistry alone are not sufficient to fully assess the effects of these discharges. Toxicity testing and evaluations of benthic invertebrate communities, in conjunction with chemical analyses, provide a more complete characterization. This study assessed relationships among three separate aspects of the benthic environment:sediment chemistry (metals, PAHs and nutrients) and particle size, sediment toxicity (ten endpoints with four benthic taxa), and benthic invertebrate community structure. In this initial survey, ten sites in five different study areas, representing a range of receiving water environments exposed to Stormwater and CSO discharges, were sampled in October 1998. Results of analyses indicated that while contaminant (metals and PAHs) concentrations were relatively high in sediments, biological effects were not evident Toxicity of sediments was low and altered benthic communities were not detected. Neither toxicity endpoints nor benthic community descriptors were related to sediment contaminant levels. To improve the power of these assessments, future investigations of Stormwater and CSO discharge impacts should use “upstream/downstream” sampling designs and study sites with minimal variability of habitat conditions.

Southern Tyrrhenian Sea

Fish assemblage in a surf zone of the southern Tyrrhenian Sea was investigated for the first time. Samples were collected during four surveys by a modified beach-seine, from June 2005 to May 2006. Overall, 42 species belonging to 19 families were recorded. Among them, Sardina pilchardus showed the highest abundance values, while Mugilids (Oedalechilus labeo and Liza aurata) were the most frequently caught species. The fish community was dominated by pelagic and gregarious species using this habitat as a foraging ground and recruitment area. Juveniles and early adults made up the largest proportion of the ichthyofauna. Fishes inhabiting the surf zone were mainly strictly benthic invertebrate feeders and invertivorous/piscivorous fish; strictly planktivorous were represented by few species but strongly dominant in terms of catch per unit effort; strictly piscivorous fish were poorly represented. Fish composition varied over the study period with the greatest abundance in May and December, and the highest richness and diversity in October.

ABSTRACT The beach of Ediz Hook, Port Angeles, Washington, was heavily oiled by Alaska North Slope (ANS) crude oil spilled subsequent to the grounding of the Arco Anchorage on December 21, 1985. Intertidal crude oil concentrations measured in beach sediments ranged from less than 50 to 20,000 ppm, with an average of 2,240 ppm. Beach reclamation efforts, concluded in April 1986, reduced average crude oil concentrations to 670 ppm. An intertidal and subtidal sediment chemistry and benthic invertebrate monitoring program was initiated at Ediz Hook in 1986 and was concluded in early 1988. Sediment chemistry data indicated a decline in mean intertidal concentrations from 670 to 110 ppm between April 1986 and July 1987. Shallow subtidal concentrations decreased from a mean of 460 to 110 ppm in the same time period. Benthic invertebrate population indices, developed with core and box sampler data, generally demonstrated a negative correlation with sediment crude oil concentrations. Organism density, taxonomic diversity and biomass increased significantly at numerous stations during the course of the monitoring studies. Successful bivalve population recruitment and growth were evident for several hardshell clam species by the fall of 1987. There was no evidence of petroleum-derived hydrocarbons in the edible tissues of salmonids (rainbow trout and Atlantic salmon) which were gathered for several months after the spill from a net-pen culturing facility in Port Angeles. Despite vigorous bird rehabilitation efforts, approximately 80 percent of the 1,917 oiled birds perished. Pre- and post-spill population census data indicate, however, that population level impacts did not occur. Various reconnaissance, monitoring and damage assessment investigations conducted during and after the spill have documented the environmental value of a rapid and effective spill response and cleanup effort. Significant impacts associated with the spill were short-term in nature and generally limited to the immediate spill area.
