“…An element is defined as soluble if it can pass through a 0.45 p pore size membrane filter. Using this definition, several workers (1)(2)(3) have reported the analysis of fresh waters with specific reference to the distribution of trace metals between particulate and soluble fractions. Stiff (I), for example, found that the fraction of total copper in particulate form varied from 43 to 87% depending on the river water under study.…”

. Can. J. Chem. 53, 661 (1 975).A simple chemical model was used to investigate the mechanisms controlling the distribution of metals between soluble and particulate fractions in natural waters. The model particulates used were potassium bentonite, hydrous MnOz, and solid humic acid. The soluble species in natural waters were modelled by soluble humic acid, tannic acid, and bicarbonate. The sorption curves for Cu(II), Cd(II), and Zn(I1) onto humic acid and Mn0z obeyed Langrnuir adsorption isotherms whereas the sorption of the above ions onto bentonite followed a Freundlich isotherm. Chemical analysis of the total model using atomic absorption spectroscopy and differential pulse anodic stripping voltammetry indicated that copper distribution depends on the pH of the suspension: above pH 6.0,50% of the copper is sorbed onto the particulates whereas the copper in solution is in a complexed form; between pH 6 and 3.8 the soluble copper is distributed between organic complexes and "free" copper ion; between pH 4.2 to 2.5 copper is being desorbed from the particulates; and below pH 2.5 all the copper is present in solution as "free" copper ion.ROBERTD. GUY, C. L. CHAKRABARTI et LAURIERL. SCHRAMM. Can. J. Chern.53.661(1975). On a utilise un modele chimique simple pour Ctudier les mCcanismes contr8lant la distribution des metaux entre les fractions solubles et particulaires des eaux naturelles. On a utilise le bentonite de potassium, le MnOz hydrate et I'acide humique solide comme rnodeles de particule. Les especes solubles dans les eaux naturelles etaient representees par I'acide humique soluble, I'acide tannique et le bicarbonate. Les courbes de sorption du Cu(II), Cd(I1) et Zn(I1) sur l'acide humique et l e M n 0~ obkissent aux isothermes d'adsorption de Langrnuir alors que la sorptiondes ions mentionnes plus haut sur la bentonite suit une isotherme de Freundlich. L'analyse chimique du modele total, utilisant la spectroscopie d'absorption atomique et la redissolution anodique par impulsions diffkrentielles indique que la distribution du cuivre depend du pH de la suspension: au dessus d'un pH de 6.0,50% du cuivre est absorbe par les particules alors que le cuivre en solution est sous forme complexte; entre les p H de 3.8 et de 6, le cuivre soluble se distribue entre les complexes organiques et des ions cuivre "libres"; entre des pH de 2.5 et d e 4.2, le cuivre est desorbt des particules; aux pH plus bas que 2.5, tout le cuivre est present en solution sous forme d'ions cuivre "libres".[Traduit par le journal]

The impact of an industrially contaminated lake on heavy metal levels in its effluent stream

Levels of cadmium and zinc in various components of Williamson Ditch (an industrially contaminated stream flowing into Palestine Lake), Trimble Creek (a stream draining Palestine Lake) and the Tippecance River (a river receiving Trimble Creek) were determined. Water, sediment, plant, fish and clam samples were analyzed for cadmium and zinc content by atomic absorption spectrophotometry. Unweighted mean metal concentrations in Trimble Creek were the following: water, 51 sug Zn/ I and 4.2 g Cd/ 1; sediment, 592 g Zn/ g and 48.8 ug Cd/ g; plants, 375 MAm Zn/ g and 7.91 Mg Cd/g;, fish, 145 Mg Zn/g and 6.o2 Mg Cd/g. These concentrations were generally lower than those found in Williamson Ditch and higher than those found in the Tippecanoe River or background levels previously reported for other aquatic ecosystems.

Concentrations of Cd, Cr, Cu, Fe, Mg, Mn, Pb, Zn, Ca and K were examined in tissues of the troglobitic (obligatory cave-dwelling) crayfish Orconectes australis australis and troglophilic (facultative cave-dwelling) species Cambarus tenebrosus. These two species cohabit a stream in Merrybranch Cave, located in rural White Co., Tennessee. Tissue concentrations of essential metals did not exhibit any trends between species. In contrast, Cd and Pb concentrations were found to be significantly greater in O. a. australis for almost all of the tissues analyzed. The higher Cd and Pb concentrations in O. a. australis are thought to be due to the increased longevity of this troglobitic species. Because of the toxicity of Cd and Pb, chronic exposure to relatively low concentrations of these metals could cause changes in mortality, fecundity or behavior in aquatic organisms possessing long life spans. The bioaccumulation of metals from low level, non-point sources is discussed in relation to life history strategies.
