Analyzed metals in road sediments from the Manoa, Hawaii watershed. (Note: previous papers have noted that this watershed has elevated background copper levels). Measured total and extractable (dilute hydrochloric acid extraction) metals in samples, which were generally collected from curb areas on roads in the watershed. Copper levels in road sediments significantly exceeded background levels. About 55% of the copper in the roadside samples was "extractable", as compared to about 18% of the "background" copper. This data (indicating copper bioavailability) and the overall copper concentrations (well above sediment effect levels guidelines) lead the authors to suggest that adverse biological impacts in the watershed were probably from copper, lead, and zinc. Brake pads, tires, and asphalt are identified as possible copper sources. Elevated antimony concentrations in roadside soils (about 10 times background) are suggested to be due to antimony use in vehicle brakes.` |
