“…Possible explanations are that cadmium accumulates over longer time periods, or cockles are able to regulate tissue loads, or that it was present (in both aqueous media and in sediments) in a form unavailable to the cockles, or that the water or sediment concentration gradient was insufficient to produce a significant result. Further work would have to be done to differentiate between these alternatives and the contribution of pore waters (Adams et al 1992).…”

“…Elucidation of the cause of observed patterns is extremely important in situations such as the one described for Lake Macquarie where potentially costly management decisions may be based on the outcome of the study. Adams et al (1992) note that the testing of bulk sediment for trace metals has been shown to be an unreliable measure of bioavailability. The sediments used in the present study were tested for 'bioavailability' using EDTA and other chemical extraction procedures by Batley (1987).…”

“…This is somewhat in conflict with the studies described in the present paper. Further studies, along the lines of the methods suggested in Adams et al (1992), would be required to fully assess the toxicology (including bioavailability of metals) of the sediments at Cockle Creek and the role that sediments play in introducing metals into biological systems.…”

Trace metal contamination of waters, sediments and animals in northern Lake Macquarie has been identified as a matter of concern by regulatory authonties. Expenmental procedures using the benthic bivalve Anadara trapezium (Sydney cockle) were developed to examine hypotheses relating to whether the cockle accumulated trace metals free in the water or from the sediment in which it is partially buried. Experiments were done in 1989 and 1991 to determine whether the concentration of trace metals in cockles was related to the concentration of metals in surrounding water or sediments. Pilot experiments indicated that it was poss~ble to translocate tubs of sediments from impacted areas to unimpacted areas with no loss of trace metals from contarnmated sediments and conversely with no increase in metals in uncontaminated sediments. Other expenments showed clearly that the presence of elevated levels of lead, copper and zinc in the water led to much greater levels in the cockles, irrespective of the concentration in surrounding sediments. There were no significant trends for cadmium. It was concluded that the sediments in which a cockle was living had little bearing on the levels of zinc, copper and lead that were accumulated in the cockle, whereas the surrounding waters had a considerable effect.

“…*Corresponding author e-mail: tf.ediagbonya@gmail.com; tf.ediagbonya@osustech.edu.ng Recently, plethora of researchers have placed emphasis on the pitfalls of elements in the environment (Verep et al, 2012;Marchand et al, 2016;Mouvet et al, 1993;Erno and Gyula, 2003) due to their deleterious effect and capacity to concentrate in the food chain (Safaa, 2015;Agnieszka et al, 2012;Adams et al, 1992;Nsenga et al, 2016). A lot of elements have been fingered as essential elements to the health of both human beings and organisms at minute quantities but harmful at higher quantities.…”

Elements pollution in water bodies and sediment have becoming increasingly a catholic focus. The knowledge of hydrogeochemical processes affecting water quality is necessary in order to assess the potential changes that occur and identify possible abatement strategy. Fifteen elements were analyzed in the sediment using AMPTEX (R), X-ray fluorescence method. The highest average concentration was recorded for Fe with an average value of 19650 ppm and the lowest average concentration was recorded for Cu with an average value of 10.86 ppm. The average concentration values recorded in this study fell with the purview of the available regulatory limits. The highest enrichment value and geo-accumulation value was recorded for Se and the highest pollution index was recorded for Fe, Mn, K, and Ca correlated well with Ni.

“…Sediment is the primary sink for various heavy metals and could also act as a source of heavy metals in aquatic systems (Adams et al, 1992;Rowlatt and Lovell, 1994). It shows relative stability over space and time, which makes more consistent assessment of heavy metal pollution possible (Pekey, 2006;Tuncer et al, 2001).…”

Large amounts of heavy metals discharged by industrial cities that are located along the middle reach of Yellow River, China have detrimental impacts on both the ecological environment and human health. In this study, fourteen surface sediment samples were taken in the middle reach of the Yellow River. Contents of Zn, Pb, Ni, Cu, Cr, Cd, As were measured, and the pollution status was assessed using three widely used pollution assessment methods, including the single factor index method, Nemerow pollution index method and potential ecological risk index. The concentrations of the studied heavy metals
