Heavy metal and PCB contamination of Bryozoan colonies in the River Meuse (Belgium)

  title={Heavy metal and PCB contamination of Bryozoan colonies in the River Meuse (Belgium)},
  author={Val{\'e}rie Henry and J. C. Bussers and J. M. Bouquegneau and Jean Pierre Thom{\'e}},
In the Meuse River (Liège area, Belgium), large amounts of three species of Bryozoans, Fredericella sultana (BLUM.), Plumatella emarginata ALL. and Plumatella fungosa (PALL.) occur. They cover 3 to 40% of the bank walls and their biomass ranges from 12 to 293 g m−2 (dry weight). In the heated waters of a nuclear power plant (Tihange) and of industries lined up along the river, colony development occurs 3 to 4 weeks earlier than at an upstream station. The heavy metal content of living colonies… Expand

Relative importance of the trophic and direct pathways on PCB contamination in the rotifer species Brachionus calyciflorus (Pallas)
Results show that in zooplankton living in polluted ecosystems, PCBs are likely to accumulate via the trophic pathway to concentrations up to 30 times higher than by direct contamination. Expand
Heavy metal contamination and antioxidant response of a freshwater bryozoan (Lophopus crystallinus Pall., Phylactolaemata).
Monthly variations of total glutathione content, catalase, and glutATHione peroxidase activities, were related with the highest metal concentrations in L. crystallinus from Lake Piediluco. Expand
Importance of substrate material for sustaining the bryozoan Pectinatella magnifica following summer rainfall in lotic freshwater ecosystems, South Korea
The substrate type on which P. magnifica grows plays an important role in resisting physical disturbances such as rainfall, and it is found that the structure of different substrates sustains P. Magnifica following rainfall. Expand
Environmental tolerances of resting stages of plumatellid bryozoans at Southern Reservoir, Dunedin, New Zealand
Germination trials were conducted to assess the effect of temperature, dry storage, and various chemicals on floatoblast germination, and Sodium hydroxide, acid clean in place (CIP) and sulphuric acid were most successful of those chemical treatments tested in preventing germination of P. vaihiriae floatoblasts.

Bacterial feeding by the freshwater bryozoan Plumatella fungosa (Pallas, 1768).
The present study demonstrates for the first time the capacity of a bryozoan to feed on bacteria and indicates the ecological role of bryozoans in water purification. Expand
Food selection by Plumatella geimermassardi Wood and Okamura, 2004 (Phylactolaemata, Bryozoa)
An experimental design was performed in order to investigate the clearance rate, food selection and efficiency of assimilation by the freshwater bryozoan species Plumatella geimermassardi, collected from the Colfiorito Marsh, Italy, during summer. Expand
The zooplankton of the lower river Meuse, Belgium: seasonal changes and impact of industrial and municipal discharges
Between 1991 and 1993, samples were collected upstream and downstream of the industrial basin and urban centre of Liège, and the zooplankton was dominated by rotifers; crustaceans (cladocerans and copepods) were less abundant; and the faunal spectrum and biomass varied with sampling location.

Patterns of higher taxon colonisation and development in sessile marine benthic assemblages at Casey Station, Antarctica, and their use in environmental monitoring
Higher taxa assemblage patterns of colonisation on settlement panels are potentially useful as a medium- to long-term monitoring tool for sheltered Antarctic nearshore waters. Expand
Phyla Ectoprocta and Entoprocta (Bryozoans)
The Phylum Bryozoa is a diverse group of benthic, suspension feeding invertebrates occurring in both freshwater and marine habitats, which includes entoprocts, which have similar features but are now considered to belong in a separate phylum. Expand
Identifying bryostatins and potential precursors from the bryozoan Bugula neritina
Extracts of 14 marine species of the Gulf of Mexico, from the sand trout to chicken liver sponge, all recently collected, are examined, to raise the question if the bryozoans are the original source of bryostatin. Expand


Impact of the Tihange nuclear power plant on the periphyton and the phytoplankton of the Meuse River (Belgium)
A survey was made from 1976 to 1981 of the possible effects of Tihange nuclear power plant on the Meuse river. Phytoplankton and periphyton were affected only during low water flow. Both decreasesExpand

Studies of herbicide toxicity in some freshwater fishes and ectoprocta
The results of studies on herbicide toxicity to fish and freshwater Ectoprocta are reported and S. mossambicus was more susceptible to Tafazine toxicity and Puntius ticto had the maximum tolerance. Expand

The Growth of Plumatella repens and P. fungosa (Bryozoa Ectoprocta) in Relation to External Factors in Danish Eutrophic Lakes

Baseline toxicity data for freshwater bryozoa exposed to copper, cadmium, chromium, and zinc
Four heavy metals were used to determine baseline toxicity data for three species of phylactolaemate bryozoa and available data indicate that bryozoans are more sensitive to these metals than many other invertebrates and fish. Expand
