Assessing the Combined Roles of Natural Organic Matter and Black Carbon as Sorbents in Sediments
Abstract
We hypothesized that two mechanisms, absorption into natural organic matter and adsorption onto combustion-derived black carbon (BC), act in parallel to bind polycyclic aromatic hydrocarbons (PAHs) to Boston Harbor sediments. To focus on BC-adsorption, we removed the non-BC fraction by combusting near shore sediments at 375 degrees C for 24 h under air, leaving ca. 16% of the reduced carbon. The isotherm for pyrene sorption onto our combusted sediment was nonlinear with a Freundlich exponent of 0.62+/-0.12 and a BC-normalized distribution coefficient (microg/ kgBC)/(microg/L)n of 10(6.25)+/-0.14. Pyrene sorption to untreated sediment was reasonably estimated using Kd = f(oc) 10(4.7) + fBC 10(6.25) Cw(0.62-1) where f(oc) was the non-BC organic carbon content, 10(4.7) was the organic carbon-normalized absorption coefficient for pyrene (L/kg(oc)), fBC was the BC content, and Cw was the dissolved pyrene concentration (microg/ L). C/H/N ratios indicated that our environmental BC differed substantially from NIST diesel soot, possibly due to inclusion of larger BC particles from near source atmospheric fallout and urban runoff. The impact of BC on total PAH sorption may explain reports of nonlinear isotherms, Koc values for PAHs that exceed their respective Kow values, and discrepancies in bioavailability between planar and nonplanar sorbates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
