“…Concentrations of metals in bottom sediments are highly correlated to particle size (Rickert, et a!., 1977;Kelly and Hite, 1981). Small particles, such as silt, clay, and organic particulates have large surface areas per unit volume, and act as chemical adsorbants (Feltz, 1980).…”

“…Bottom sediments record intermittant discharges and historical inputs of metals and other constituents that may not be detected by periodic water sampling (Rickert, et al, 1977;Feltz, 1980;Wahlen and Thompson, 1980). For example, 23 micrograms of mercury per kilogram of sediment were measured in a Lake Ellyn sediment sample collected near Main Inlet on May 29, 1981, but no mercury was detected in inflow or outflow samples collected on that day.…”

SUSPENDED SEDIMENT AND METALS REMOVAL FROM URBAN RUNOFF BY A SMALL LAKE¹

A small lake in the Chicago Metropolitan Area was from 91 to 95 percent efficient in removing suspended sediment and from 76 to 94 percent efficient in removing copper, iron, lead, and zinc from urban runoff. Sediments accumulated in the lake in the form of an organic‐rich mud at an average rate of 20 millimeters per year; this reduced lake storage and covered potential habitat for aquatic organisms. Copper, lead, and zinc concentrations were closely associated with suspended‐sediment concentrations and with silt‐ and clay‐sized fractions of lake sediment. Although concentrations of mercury and cadmium were near detection limits in runoff, measurable concentrations of these metals accumulated in the lake sediments.

“…The concentration of trace element on streambed sediment is strongly affected by the particle‐size distribution of the sample (Rickert et al 1977; Wilber and Hunter 1979). As particle size decreases, concentrations of trace elements generally increase (Horowitz and Elrick 1988).…”

Streambed-sediment samples were collected in the Sarbaz River Basin in Sistan and Baluchestan Province, east of Iran, to characterize the occurrence and distribution of lead in natural and anthropogenic sites of the basin. During June and July 2008, stream sediment was collected at 30 sites, and the samples were analyzed for lead. Sites sampled represented agricultural, mining, mixed, rangeland, recreation, and residential land uses and background conditions. Lead was detected in all collected stream-sediment samples of the basin. Most of the lead concentration was associated with the smaller part of the 2 grain-size fractions: 2000 to 43 microm and <43 microm. The range in concentrations of lead at urban/rural sites generally was higher than the range of concentrations at nonurban/rural sites. Sediment from 2 distinctly different rock types in urban/ rural areas were not significantly different (t = 0.1330, p = 0.8955) for concentrations of lead. Concentrations of lead were not significantly different (t = 0.0845, p = 0.6865) between main-stem sites and tributary sites. Concentrations of lead exceeded established sediment-quality guidelines for adverse effects on aquatic biota at most of the urban/rural sites in the study area.

“…Plot metal concentrations in fractionated fine materials (see HData Program") on normal probability paper according to the method described by Velz (1970, p. 522-542). Concentrations which follow a normal distribution are suggestive of natural background and all other concentrations are indicative of pollution (see Rickert, Kennedy, McKenzie, and Hines, 1976).…”

“…In contrast to the programs for the other three project elements, no attempt was made to collect the kinds and intensities of data required to define cause-effect relationships. By applying the two step screening process to the collected data, it was possible to detect several cases of trace-metal pollution and to identify the sources (Rickert, Kennedy, McKenzie, and Hines, 1976).…”
