“…Mines in areas such as the Ystwyth valley, some 30 km SE of Borth Bog, continued to be heavily exploited from the eighteenth century and a record of pollution consistent with this evidence is recorded in local blanket peat (Mighall et al, 2002b). Furthermore, Lee and Tallis (1973), Livett et al (1979), Livett (1988) and Rothwell et al (2007) all record increases in Pb and Zn from Medieval times, then a dramatic increase during the late 1700s, followed by a reversal during the first half of the 1900s. However, no such record exists at Borth Bog.…”

“…The sedimentation of these particles then creates deposits which constitute micropollutant reservoirs with pollutant concentrations 1000 to 5000 times higher than those in water (Livett 1988). The remobilization of sedimentary micropollutants, either by natural processes (resuspension during tidal movements and periods of high water turbulence) or artificial means (management-related and dredging operations), has been demonstrated in numerous studies (e.g.…”

The bioavailability of Cd, Cu and Zn from a metal-contaminated sediment was studied using Mytilus galloprovincialis embryos and larvae exposed to sediment elutriates. The elutriate concentrations tested were always lower than the threshold at which abnormal larval development appears. The Cd, Cu and Zn contents of the sediment, of the elutriate and of the larvae, as well as the larval growth, the condition index (CI), and the induction of metallothionein (MT) in the larvae were measured. The CI was only affected after 96 h of exposure, principally at the highest elutriate concentration (25%, corresponding to 0.1435 µg Cd l -1 and 14 µg Zn l -1). Cd, Cu and Zn bioaccumulation was observed (48 and 96 h), in whole larvae as well as in the cytosolic fraction of their tissues. For the individual treatments (controls or different degrees of exposure), the lowest metal concentrations were observed in larvae after 96 h exposure, indicating biological dilution. Metallothionein induction in larvae was observed after 96 h exposure at the lowest elutriate concentrations tested, and was always strongly correlated with increasing metal contents in the cytosolic fraction. These relationships were significant for all 3 metals studied either individually or combined. The results indicate that these 3 metals are bioavailable to M. galloprovincialis larvae and that MT induction constitutes a more sensitive indicator of heavy metal pollution than embryotoxicity or larval growth experiments.

“…The latter characteristic was important for two reasons. Firstly, benthic organisms are more exposed to heavy metal contamination since it mainly accrues within the sediment (heavy metals have a tendency to adsorb to sediment particles) and their concentrations in marine sediments may be several orders of magnitude higher than in the overlying water column (Livett, 1988). Secondly, the association between pollutants and sediments can be of a very long duration and it may have critical deleterious effects on organisms living on and within the bottom sediments (His et al, 1999).…”

“…The respective experimental metal concentrations (given in Table 1) were decided upon, firstly, a comprehensive literature survey to establish the influences and respective concentrations of , 1988;McKenney and Neff, 1979;Ober et aldate?, Odendaal and Reinecke 1998), and secondly, test experimentation using the methodologies and concentrations, gleaned from the literature, for each respective metal solution on eggs and larvae of C.kraussi.…”

This investigation explored the effect of the heavy metals Pb (Pb 2+ ) and Zn (Zn 2+ ) individually and in combination (i.e. three metal solutions) on both the brood and larval development of the burrowing crustacean, Callianassa kraussi. Egg and larval mortalities at factorial (4x7) combinations of salinity (20, 24, 30, 35 mg/l) and seven respective metal concentrations were examined. The results provided various statistically significant trends. Individual concentrations of Pb and Zn at various salinities impacted negatively upon the brood and larval development of Callianassa kraussi. Increasing the specific concentrations of both metals further demonstrated a negative influence, especially on brood development and to a lesser extent on larval development of Callianassa kraussi. Comparing the toxicity of the three concentrations of metals to Callianassa kraussi brood and larval development, it was found that individual Pb concentrations exhibited the least mortality (LC 50 Pb-eggs-35ppm = 1.580 mg·l -1 whilst individual Zn concentrations displayed considerably higher mortality (LC 50 Zn-eggs-35ppm =0.066 mg/l) but that the combination of Zn and Pb concentrations produced the highest mortality =0.036 mg·l -1). Varying salinities in permutation with varying metal concentrations exhibited a significant detrimental influence on the brood and larval development of Callianassa kraussi, notably at the lowest salinities in combination with the highest metal concentrations.
