“…The discrepancy in copper sensitivity between the results of this work and that of others may be because the previous work was done with pure cultures or activated sludge, and the copper tolerance for those biological systems may be much different from the biofilm grown in the reactors used in this project. Another possible explanation is that organic matter contains functional groups (Sarathy and Allen, 2005) that bind metals to form less bioavailable complexes (Loveless and Painter, 1968;Dodge and Theis, 1979;Crecelius et al, 1982) that are therefore less inhibitory (Kim et al, 2006). The humics used in this research may have acted in this capacity although the copper in the reactor water was detected in the ionic form.…”

Indigenous drinking water organisms were used to establish nitrification in glass reactors containing copper or polyvinyl chloride (PVC) surfaces. The reactors were fed soil-derived humics as the organic carbon source and ammonium sulfate as the nitrogen source in biologically treated tap water. Water in the reactors was stagnant for 8 h and then flowed for 5 min to simulate conditions in household plumbing. Following the establishment of complete nitrification (conversion of ammonia to nitrate) in both reactor types, various inhibitors of nitrification were tested followed by a period where recovery of nitrification was observed. In one PVC reactor, copper was gradually introduced up to 1.3 ppm. To ensure that most of the copper was in the ionic form, the pH of the influent was then gradually lowered to 6.6. No significant change in nitrification was observed in the presence of copper. Chlorite was introduced into copper and PVC reactors at doses increasing from 0.2 ppm to 20 ppm. There was limited effect on the PVC system and inhibition in the copper reactor only at 20 ppm. Chloramine was tested at chlorine to ammonia ratios ranging from 0.5:1 to 5:1. Nitrification activity was impacted significantly at a 5:1 ratio and ultimately stopped, with the fastest response being in the copper system. Whenever a control mechanism was tested, there was increased release of copper from the reactors with copper coupons. In all cases, nitrification recovered when inhibitors were removed but the rates of recovery differed depending on the treatment method and coupon surface.

“…the highest concentrations of Pb observed in the deposit feeding clam Scrobicularia plana are 500 yg g -', while concentrations never exceed 20 µg g -' in Macoma balthica, an ecologically similar animal within the same family (Bryan et al, 1980 ;. 7) Feeding strategy also influences bioaccumulation, as illustrated by differences in metal uptake between suspension feeders and deposit feeders exposed in the same metal-enriched system (Crecelius et al, 1982 ;Bryan, 1985 ;Loring & Prosi, 1986) . However, it is encouraging that a variety of benthic species seem to follow similar trends in response to enrichment in nature .…”

Can we determine the biological availability of sediment-bound trace elements?

It is clear from available data that the susceptibility of biological communities to trace element contamination differs among aquatic environments . One important reason is that the bioavailability of metals in sediments appears to be altered by variations in sediment geochemistry . However, methods for explaining or predicting the effect of sediment geochemistry upon metal bioavailability are poorly developed . Experimental studies demonstrate that ingestion of sediments and uptake from solution may both be important pathways of metal bioaccumulation in deposit/detritus feeding species . Relative importance between the two is geochemistry dependent . Geochemical characteristics of sediments also affect metal concentrations in the tissues of organisms collected from nature, but the specific mechanisms by which these characteristics influence metal bioavailability have not been rigorously demonstrated . Several prerequisites are necessary to better understand the processes that control metal bioavailability from sediments . 1) improved computational or analytical methods for analyzing distribution of metals among components of the sediments ; 2) improved computational methods for assessing the influences of metal form in sediments on sediment-water metal exchange ; and 3) a better understanding of the processes controlling bioaccumulation of metals from solution and food by metazoan species directly exposed to the sediments . Such capabilities would allow mechanistic explanations essential to the development of practical tools sought for determining sediment quality criteria for metals .

“…The species-specific aspects of bioaccumulation could result from difference in feeding mode (filter feeding vs deposit feeding), exposure routes (dissolved vs food or benthic vs pelagic food web) and duration of exposure, as well as internal processes such as storage, detoxification and loss (Jackim et al 1977, Roesijadi & Robinson 1994, Wallace & Lopez 1996, Reinfelder et al 1997. Experimental studies have shown, for example, differences in metal uptake between suspension feeding and deposit feeding bivalves exposed in the same metal-ennched system (Crecelius et al 1982, Bryan 1985 or between benthos that feed from the water column versus benthos that feed on the sediments (Hare et al 1994, Warren et al 1998. It is proposed that some organisms can internally maintain or regulate approximately constant tissue levels of selected elements (most commonly Zn), regardless of external metal concentrations (Rainbow et al 1990 and references therein).…”

Radiotracer studies were employed to quantitat~vely compare the biokinetics of uptake from the dissolved phase (influx rates) and loss (efflux) between 2 bivalves, Potamocorbula arnurensls and Macoma balthica, and among the metals Cd, Cr and Zn. Effects of salinity on influx rate were evaluated in these 2 highly euryhaline species as were effects of animal size on uptake and loss. Metal speciation and biological attributes interacted to differentiate bioaccumulation processes among metals and between species. Influx rates of the 3 metals (pg g-I [dry wt] d-') increased linearly with dissolved metal concentrations. Influx rates of Zn in both clams were 3 to 4x those for Cd and 15x those for Cr. However, influx on the basis of free ion activities would be faster for Cd than for Zn. Relative influx rates among the metals were similar in the 2 bivalves. But, absolute influx rates of all 3 metals were 4 to 5 x greater in P. arnurensis than in M. balthica, probably because of differences in biological attributes (i.e. clearance rate or gill surface area). As salinity was reduced from 30 to 5 psu, the influx rate of Cd for P. amurensis increased 4-fold and that for M. balthica increased 6-fold, consistent with expected changes in speciation. However the influx rates of Cr in both clams also increased 2.4-fold over the same range, indicating a biological contribution to the salinity effect. Influx rates of Zn were not significantly affected by salinity. Weight specific metal influx rates (pg g-' [dry wt] d-') \Yere negatively correlated with the tissue dry weight of the clams, but most rate constants determining physiological turnover of assimilated metals were not affected by clam size. The exception was the rate constant for Cd loss, which resulted in faster turnover in large M. balthica than in smaller clams. The rate constant of loss for P. arnurensis increased in the order of Cd (0.011 d-') < Zn (0.027 d-l) < Cr (0.048 d-l). This was different from the hierarchy of rate constants for M. balthica: Zn (0.012 d-l) < Cd (0.018 d-l) < Cr (0.024 d.').
