The Role of Carbonaceous Materials in Pavement Dust, Soils, and Lake Sediments on the Fate of Organic Pollutants in Small Urban Watersheds
Abstract
dc:descriptionField samples were fractionated into light (LFr), heavy (HFr), and condensed CMs (CCMs) fractions with sequential physical and chemical treatment. These fractions and bulk samples were characterized with elemental analysis, Fourier transform infrared spectroscopy, specific surface area measurement, and solid state 13C nuclear magnetic resonance spectroscopy. Sorption isotherms of phenanthrene to these fractions and bulk samples fitted with Freundlich models are nearly linear (N = 0.90--1.00), suggesting a partitioning-dominated mechanism which likely is attributed to the sorption contribution from asphalt and coal tar. No statistically significant correlation was observed between CM properties and sorption parameters. The phenanthrene sorption to bulk samples is dominated by CCMs in HFr fractions.
