The Blackstone River, which empties into the northernmost sector of the bay system, was the largest source of riverine PCBs, contributing ∼ 70% of the 12 kg of Ar 1254 transported by the evaluated rivers per year. An additional 2.5 kg, annually, may be coming from freshwater inputs not explicitly measured in this study, giving a total fluvial input of ∼ 14 kg Ar 1254 per year. A single wastewater treatment facility, the Fields Point plant, which also discharges into the northern sector of the bay, contributed 70% of the 5.9 kg year−1 of Ar 1254 attributable to municipal inputs. Therefore, an estimated 20 kg of particulate Ar 1254 enters the bay, annually, from these sources, under dry weather conditions. Ar 1254 inputs represented ∼ 70% of the total Aroclors present in the samples (i.e., Ar 1242, Ar 1254, and Ar 1260). Of note was the almost exclusive presence of decachlorobiphenyl in the river samples.

The petroleum products considered were No. 2 and No. 6 fuel oils, used and virgin crankcase oils, and gasoline. Source materials included street dust, roadside soil, roadside vegetation, and atmospheric fallout; and the land use categories were commercial, residential, interstate highway, and industrial areas. The samples were compared on the basis of hydrocarbon (saturated and aromatic) and trace metal (Cd, Pb, Mn, Cu, Fe, Zn) loadings and distributions. Results indicated that the hydrocarbon content in runoff at all four land use sites originated primarily from used crankcase oil, with a small amount of No. 2 fuel oil detected at the industrial site. Only a small portion of the crankcase oil component came from the sources surveyed, and the majority of this oil probably came from: (1) oil drops within the driving lanes on the road surfaces or deposits in parking areas, and/or (2) direct dumping of waste crankcase oil down storm drains.

Previous studies have characterized the inorganic and organic constituents in urban runoff (Pitt 1979 and Hoffman et al. 1982 and 1983), and it was shown that many of these pollutants are susceptible to quiescent settling and removal from the water column.

We are examining the utility of dinoflagellate cysts (or hypnozygots produced by dinoflagellates, which can be preserved in sediments) as high-resolution indicators of environmental conditions in estuaries. We measured chemical contamination and analyzed dinoflagellate cyst assemblages in surface sediments collected from three neighboring embayments of Buzzards Bay, Massachusetts ...

than three million liters of No. 2 fuel oil into Rhode Island Sound near Matunuck, Rhode Island. ... more than three million liters of No. 2 fuel oil into Rhode Island Sound near Matunuck, Rhode Island. The toxicity and chemistry of this oil in two subtidal sediments were followed for more than 9 months. Maximum concentrations of polycyclic aromatic hydrocarbons (PAHs) in the sediments reached 730 lgag dry weight (DW). Water samples taken immediately after the spill were phototoxic to embryos of the bivalve Mulinia lateralis. Total PAHs and toxicity to the amphipod Ampelisca abdita were high immediately after the spill, decreasing to background values (10 lgag DW and`20% mortality, respectively) after 6 months. Changes in toxicity to A. abdita related closely to changes of PAH concentrations in sediments. Weathering and degradation of the oil were followed by using ratios of PAHs, and alkanes as indicators. To distinguish eects of local boat trac from spill eects, these ratios plus distributions of PAHs in sediments from a nearby marina were used. Ó 1999 Published by Elsevier Science Ltd.
