“…Luoma et al (1983) showed that tolerance to Cu in populations of Macoma balthica and the copepod Acartia clausivaried as much as 10-fold over short distances. Rygg (1985) suggested that a Cu concentration of 200 pg g -' represented a threshold concentration for polychaete communities.…”

The Fa1 estuary system, southwest England, is an ideal site for a natural experiment on the effects of long-term contamination by heavy metals on intertidal mudflat meiofauna communities. Five creeks were chosen in which sediment concentrations of heavy metals differed by orders of magnitude, namely Restronguet (mean Cu concentration 2532 pg g -' ) , Mylqr (1272 pg g-'), Pill (697 pg g -l ) , St Just in Roseland (332 pg g-l) and Percuil (165 pg g-l). Univariate and multivariate analyses of the meiofauna1 community structure in these creeks suggest that nematodes are more responsive to sediment heavy metal concentrations than copepods, as indices of diversity and changes in nematode community structure as revealed by multivariate analyses were closely correlated with metal levels For copepods differences could only be detected in Restronguet creek, where endobenthic species were absent. Analyses suggest that some nematode species may have developed different tolerance mechanisms for survival in areas with high heavy metal concentrations.

“…The concentrations of copper in sediments have been inferred to be causally related to the species composition of infauna in Norwegian fjords (Rygg 1985a). Effects on infaunal species con~position were detected at sediment concentrations ranging from 5 to 10 times above presumed background concentrations.…”

The infauna of intertidal and subtidal marine sediments at 18 sites near a large lead-zinc smelter In Spencer Gulf, South Australia, was sampled twice about 6 mo apart. The sampled habltats were bare intertidal mudflats, intertidal seagrass [Zostera sp.) beds, subtidal seagrass (Posidonia spp.) beds, and unvegetated sedlments at 5 to 10 m depth. The Infauna consisted of 372 identifiable taxa, malnly polychaetes, molluscs and crustaceans. The number of taxa at each site and time showed no s~mple relationship with the concentrations of trace metals In sediments, habitat type or time of sampling. However, the patterns of distribution, analysed uslng frequencies of occurrence of taxa derlved from mult~variate classification and ordination techniques, were related to the sediment concentrations of As, Cu, Mn, Pb, Sb and Zn. The extremely high concentrations of these trace elements (probably mainly Pb and Zn) appeared to affect both the abundances and distribution of many infaunal species. The multivariate techniques could detect which species were affected in the most metal-polluted sites (the intertidal sites). However, in the less-polluted subtidal sites, patterns in species composition were detected but only a few individual species could be unambiguously correlated to the presence of the metals. The polluted intertidal sediments, which had some of the highest metal concentrations ever recorded in marine sediments (Pb up to 5270 pg g-' and Zn up to 16700 pg g-'), supported 42 taxa. The polychaetes Heteromastus filiformis, Capitella 'capitata' and Glycera americana, and the crustacean Tanais dulongii were very abundant in these sites; they apparently can selectively exploit the metalcontaminated conditions. C. 'capitata'and 7 dulongii were found almost exclusively in these sites. In contrast. 15 spccicb of polychaetes, 5 crustaceans and 4 molluscs found elsewhere in the study area. representing 26, 20, and 17"% of these intertidal taxa respectively, were not found in the metal-polluted sites. No tdxonomic select~vity in the effects of the metals was detected amongst the 3 major groupspolychaetes, molluscs dnd crustaceans. Future studies may, therefore, be able to sample indicator species from only one of these major groups to determine the spatial extent of ecological effects or to monitor metal effects in this area.

“…However, excessive amounts of heavy metals enter the coastal environment via anthropogenic industrial activities, mining activities, agriculture (run-off), and sewage disposal [33,34], are considered toxic and restrain the growth and propagation of macrobenthic organisms [35][36][37]. Rygg has found negative correlations between species diversity in macrobenthic community and copper concentrations and organic matter [38]. McLusky et al [39] also showed that higher concentrations of Cu were toxic to macrobenthos and lowered their diversity.…”

Laizhou Bay, located in the northwest of Shandong Peninsula, has complex transitional environments between terrestrial and marine ecosystems. In the present study, a total of 122, 131, and 139 species were collected in spring, summer, and autumn 2011, respectively. Species constitutions of macrobenthos were grouped into four phyla, of which annelida were the most abundant phylum, the average biomass proportion of echinodermata was the lowest, and the proportion of important species for mollusca was the highest. The structure of the macrobenthic community showed significant differences between sites, and greater divergence was observed between the third site (S03) and other stations. The ABC plots showed that the biomass curve lay below the abundance curve, and the W-statistic value was negative. The result of the BOPA index showed that two stations had moderate ecological status in spring and that there were two heavily polluted sites and one moderately polluted site in summer. The BIO-ENV analyses indicated that the grain-size fractions together with trace metals (Hg, Pb, Zn, Cu, and Cr) could be considered as the major environmental variables influencing the macrobenthic patterns. The results together demonstrated that the macrobenthic communities in Laizhou Bay were negatively affected, perhaps by the tremendous impact of heavy metals in the sediments.
