TL;DR: In this article, matching biological and chemical data were compiled from numerous modeling, laboratory, and field studies performed in marine and estuarine sediments, and two guideline values (an effects range low and an effects range median) were determined for nine trace metals, total PCBs, two pesticides, 13 polynuclear aromatic hydrocarbons (PAHs), and three classes of PAHs.
Abstract: Matching biological and chemical data were compiled from numerous modeling, laboratory, and field studies performed in marine and estuarine sediments. Using these data, two guideline values (an effects range-low and an effects range-median) were determined for nine trace metals, total PCBs, two pesticides, 13 polynuclear aromatic hydrocarbons (PAHs), and three classes of PAHs. The two values defined concentration ranges that were: (1) rarely, (2) occasionally, or (3) frequently associated with adverse effects. The values generally agreed within a factor of 3 or less with those developed with the same methods applied to other data and to those developed with other effects-based methods. The incidence of adverse effects was quantified within each of the three concentration ranges as the number of cases in which effects were observed divided by the total number of observations. The incidence of effects increased markedly with increasing concentrations of all of the individual PAHs, the three classes of PAHs, and most of the trace metals. Relatively poor relationships were observed between the incidence of effects and the concentrations of mercury, nickel, total PCB, total DDT and p,p′-DDE. Based upon this evaluation, the approach provided reliable guidelines for use in sediment quality assessments. This method is being used as a basis for developing National sediment quality guidelines for Canada and informal, sediment quality guidelines for Florida.

TL;DR: In this paper, a seasonal sampling campaign was undertaken at an urban location in Birmingham, U.K., in which high-volume samplers were used to collect particulate and vapor-phase polycyclic aromatic hydrocarbons (PAHs) by means of filter papers and polyurethane foam plugs.
Abstract: Intensive seasonal sampling campaigns were undertaken at an urban location in Birmingham, U.K., in which high-volume samplers were used to collect particulate- and vapor-phase polycyclic aromatic hydrocarbons (PAHs) by means of filter papers and polyurethane foam plugs. Eighteen PAH species were determined by reversed-phase HPLC. Additionally, the suspended particle loading of the air was measured gravimetrically. Dichotomous stacked filter units (DSFUs) were run simultaneously with the high-volumes enabling the collection of particulate matter representative of fine (<2.1 μm) and coarse sized (2.1−10 μm) fractions. Filters from the DSFUs were analyzed for 19 metal species [by proton induced X-ray emission (PIXE)], ammonium, elemental carbon, and various anions. Metal and PAH concentrations were observed to be broadly in line with concentrations measured at other urban areas throughout the U.K. Chemical source apportionment studies took the form of principal component analysis (PCA) followed by multi-line...

TL;DR: The weight-of-evidence approach to the development of sediment quality guidelines (SQGs) was modified to support the derivation of biological effects-based SQGs for Florida coastal waters, which were demonstrated to provide practical, reliable and predictive tools for assessing sediment quality.
Abstract: The weight-of-evidence approach to the development of sediment quality guidelines (SQGs) was modified to support the derivation of biological effects-based SQGs for Florida coastal waters. Numerical SQGs were derived for 34 substances, including nine trace metals, 13 individual polycyclic aromatic hydrocarbons (PAHs), three groups of PAHs, total polychlorinated biphenyls (PCBs), seven pesticides and one phthalate ester. For each substance, a threshold effects level (TEL) and a probable effects level (PEL) was calculated. These two values defined three ranges of chemical concentrations, including those that were (1) rarely, (2) occasionally or (3) frequently associated with adverse effects. The SQGs were then evaluated to determine their degree of agreement with other guidelines (an indicator of comparability) and the percent incidence of adverse effects within each concentration range (an indicator of reliability). The guidelines also were used to classify (using a dichotomous system: toxic, with one or more exceedances of the PELs or non-toxic, with no exceedances of the TELs) sediment samples collected from various locations in Florida and the Gulf of Mexico. The accuracy of these predictions was then evaluated using the results of the biological tests that were performed on the same sediment samples. The resultant SQGs were demonstrated to provide practical, reliable and predictive tools for assessing sediment quality in Florida and elsewhere in the southeastern portion of the United States.
