    The mean benthic flux of ammonia over the period of study was ab ± 13, kg-N/yr. Advective flux estimates from the external exchange over the tidal cycle ranged from −50 to kg-N/yr of ammonia. This difference of nearly two orders of magnitude suggests that benthic flux is a major source of ammonia to the water column for.

To understand the differences in metal exposure occurring between laboratory- and field-based bioassays, we investigated changes in metal.

The benthic flux calculations indicate that the sediment is generally a source of dissolved Zn, Cu, Mn, and, possibly, Pb to the overlying water column. These benthic fluxes are compared with two other major sources of metals to Coeur d'Alene Lake-the Coeur d'Alene and St. Joe Rivers.

This report presents porewater and selected water column data collected from Coeur d'Alene Lake in September of Despite probable oxidation of the porewater samples during collection Author: L.

Balistrieri. While these data and calculations provide preliminary information on benthic metal fluxes in Coeur d’Alene Lake, further work is needed to verify their direction and magnitude. The benthic flux calculations indicate that the sediment is generally a source of dissolved Zn, Cu, Mn, and, possibly, Pb to the overlying water column.

Benthic fluxes of metals, particularly zinc, are significant sources of metals to the water column of Lake Coeur d'Alene (Kuwabara et al., ) and presumably also in the chain lakes (which are.

Sediments are active recipients of anthropogenic inputs, including heavy metals, but may be difficult to interpret without the use of numerical models that capture sediment-metal interactions and provide an accurate representation of the intricately coupled sedimentological, geochemical, and biological processes.

The focus of this study is to present a benchmark problem on heavy metal. Benthic flux of metals and nutrients into the water column of Lake Coeur d'Alene, Idaho: Report of an August,pilot study.

Water-Resources Investigations Report   Calculated fluxes ranging from – × 10 8 atoms m −2 d −1 show that a completely independent estimate of benthic fluxes matches well with the average Ra flux derived from the water column Ra inventory ( ± × 10 8 atoms m −2 d −1), reinforcing the argument that benthic input is the primary source of Ra to the system.

The benthic flux calculations indicate that the sediment is generally a source of dissolved Zn, Cu, Mn, and, possibly, Pb.

Coeur d'Alene Lake in northern Idaho is fed by two major rivers: the Coeur d'Alene River from the east and the St.

Joe River from the south, with the Spokane River as its outlet to the north. Benthic flux of metals – Flux estimates from both lander deployments and core-incubations, when averaged over the affected lake area, were of similar magnitude as the dissolved-metal flux from the Coeur d’Alene and St.

Joe Rivers even with oxygenated bottom waters in the lake (Table 9; Metals discussion). This is consistent. Estimates of nutrient fluxes. The vertical diffusional flux of dissolved nutrients from sediments to the overlying water may be calculated from the pore water dissolved gradients (dC/dZ) Z=0 across the sediment–water interface, according to Fick's law in one dimension (Azcue et al., ) represented by Eq.

A survey of heavy metal concentration in the sediments was carried out in order to estimate the extent and degree of heavy metal contamination in the southern part of the Coeur d'Alene lake.

INTRODUCTION During recent years, increased interest in the environment has resulted in consider- able attention being given to pollution caused by industry. A field study was conducted between August, to provide the first direct measurements of the benthic flux of dissolved (micron filtered) solutes between the bottom sediment and water column at two sites in Lake Coeur d'Alene, Idaho.

Trace metals (namely, cadmium, copper, manganese, mercury species, and zinc) and nutrients (namely, ammonia, nitrate plus nitrite, oxygen. Water chemistry. The Coeur d’Alene river and lake waters near Harrison are dilute Ca–SO 4 waters typically with Ca and SO 4 2-concentrations ranging 5–20 mg/L, and with Mg, Na and Cl concentrations generally a few mg/L or less.

The studies of Balistrieri,Winowiecki,Toevs et al., provide most of the available pore-water chemical analyses from Lake Coeur d’Alene.The waters and sediments of the Coeur d’Alene River (CdAR) in northern Idaho have been impacted by decades of mining operations within the Coeur d’Alene mining district.
