Abstract
Environmental Context. Elemental carbon in anthropogenic pollutants has been linked in a general way to adverse health effects. Carbon may be present in many forms, including charcoal, graphite, organic (such as fuel- and biomass-derived), and inorganic. However, the boundaries between the various forms of carbon are not clearly delineated, which impedes more precise carbon–health linkage. This paper points towards a straightforward, general method for quantifying elemental carbon in environmental samples. Abstract. A preliminary report is given of a nondestructive diffuse reflectance infrared Fourier transform spectra (DRIFTS) instrumental technique to quantify elemental carbon (EC) in marine sediments. Prolonged ball-milling produces a new IR absorption band at 1590 cm−1, whose intensity correlates well with the mass of EC in the sample.
