“…Indeed, 93% of sample stations in Trenton Channel exceed threshold effect level sediment quality guidelines for PAHs and PCBs ) and more than 16% of sample stations in the Detroit River exceed the severe effect level for heavy metals, with the maximum concentrations being confined to the Trenton Channel (Szalinska et al 2006). Average hydrocarbon levels in the Detroit River are 1,195 parts per million (ppm) whereas these levels are only 77 ppm in the Belle River (Nagy et al 1984).…”

Aquatic ecosystems are major sinks for pollutants which can have adverse effects on biodiversity. Thus, it is important to understand the nature of pollution-induced change in aquatic ecosystems. We show that brown bullheads (Ameiurus nebulosus) may have evolved in response to chronic pollution exposure. We collected adults from the Detroit River (polluted site) and Belle River (control site). Both adults and common-garden raised juveniles were tested for aggression, locomotion, and escape response using consecutive unchallenged (clean) and challenged (polluted) trials. Detroit River fish were more aggressive than Belle River fish when challenged. Furthermore, Belle River fish showed increased locomotion when exposed to pollutants, whereas Detroit River fish were unaffected. The consistent difference in adult and juvenile behaviour across trials suggests a genetic response to pollution. Escape response on the other hand, showed inter-population differences, but no consistency between adults and juveniles, indicating that this behaviour is influenced by non-genetic factors. We discuss our data with respect to the potential adaptation of populations to pollution and the implications for prioritizing remediation efforts.

“…Petroleum hydrocarbons appear in general to be transported in association with suspended sediment particles in Lakes St. Clair, Erie, and Ontario. Highest concentrations are found in sediments close to major cities and in areas where fine-sized sediment particles can settle to the lake bottoms (Nagy et al, 1984). Western Lake Erie, which receives the discharge from the heavily industrialized and urbanized Detroit River, has the largest accumulation of petroleum hydrocarbons.…”

“…Western Lake Erie, which receives the discharge from the heavily industrialized and urbanized Detroit River, has the largest accumulation of petroleum hydrocarbons. The sediments of shallow Lake St. Clair (ca 6 m) contain low concentrations of petroleum hydrocarbons (Nagy et al, 1984), yet Meyers (1984) notes that UCM components constitute nearly 80% of the total hydrocarbons in a 20 cm core of sediment from this lake. The organic matter characteristics of this core closely resemble those of Core 58 from southern Lake Huron, which is made up of glaciolacustrine clay estimated to be 12 Kyr old.…”

The factors affecting the amounts and types of organic matter in lacustrine sediments are summarized in this review, and synthesis, of published studies. Biota hving in the lake and in its watershed are the sources of the organic compounds initially contributed to the lake system. Microbial reworking of these materials during sinking and early sedimentation markedly diminishes the total amount of organic matter while replacing many of the primary compounds with secondary ones. Much of the organic matter content of sediments is the product of this microbial reprocessing. Various organic matter components of lake sediments nonetheless retain source information and thereby contribute to the paleohmnological record. Carbon/nitrogen ratios of total organic matter reflect original proportions of algal and landderived material. Carbon isotopic compositions indicate the history of lake productivity and carbon recycling. Biomarker compounds provide important information about contributions from different biota. Sterol compositions and chainlength distributions of n-alkanes, n-alkanoic acids, and n-alkanols help distinguish different algal and watershed sources and also record diagenetic alterations. Stabilization of functional-group-containing biomarkers by conversion into saturated or aromatic hydrocarbons or by incorporation into bound forms improves their preservation and hence record of source information. Lignin components provide important evidence of watershed plant cover, and pigments reflect algal assemblages. The interplay of the factors influencing the organic matter content of lake sediments is illustrated by overviews of sedimentary records of four lake systems-Lake Biwa (Japan), Lake Greifen (Switzerland), Lake Washington (Pacific Northwest), and the Great Lakes (American Midwest).

“…Some pollutants, such as chlorinated benzenes, are metabolized only under aerobic conditions, while the mineralization of most halogenated aliphatic compounds requires an anaerobic environment (3,29). Aromatic hydrocarbons such as benzene, toluene, and xylenes are ubiquitous pollutants (7,19,20,21), and they are rapidly degraded under aerobic conditions (3,9,18). In anaerobic microbial cultures from lake sediments and sewage sludge (12,22), however, they have been found to be very recalcitrant.…”

Up to 0.4 mM 1,3-dimethylbenzene (m-xylene) was rapidly mineralized in a laboratory aquifer column operated in the absence of molecular oxygen with nitrate as an electron acceptor. Under continuous flow conditions, the degradation rate constant (pseudo-first order) was >0.45 h-1. Based on a carbon mass balance with [ring-14C]m-xylene and a calculation of the electron balance, m-xylene was shown to be quantitatively (80%) oxidized to CO2 with a concomitant reduction of nitrate. The mineralization of m-xylene in the column also took place after reducing the redox potential, E', of the inflowing medium with sulfide to <-0.11 V. Microorganisms adapted to growth on m-xylene were also able to degrade toluene under denitrifying conditions. These results suggest that aromatic hydrocarbons present in anoxic environments such as lake sediments, sludge digestors, and groundwater infiltration zones from landfills and polluted rivers are not necessarily persistent but may be mineralized in the absence of molecular oxygen.
