Summary |
 |
| The relationship between metal exposure
concentration and effect in plants and aquatic organisms is not straightforward, because
the bioavailability of metals from the environmental compartment in which the organisms
are exposed is situation-specific. Both aquatic organisms and plants are exposed to metals
in solution, which are in dynamic equilibrium with the soil solid or sediment phase; in
addition, aquatic organisms are also exposed to metals in prey. In this project, we
propose to explore the linkages between metals that are "available" in various
soil and aquatic compartments and their accumulation in the organisms that occupy those
compartments. Parallels between terrestrial and aquatic systems will be sought, towards
the goal of harmonious regulations for metals in both situations. The organisms to be
considered include herbaceous and woody monocots and dicots, bryophytes and benthic
invertebrates. |
