The incorporation of discreet nucleation events into models for the current density has been reviewed by Scharifker et al. [111]. The current density is found by integrating the current over a large number of nucleation sites whose distribution and growth rates depend on the electrochemical potential field and the substrate properties. The process is non-local because the presence of one nucleus affects the controlling field and influences production or growth of other nuclei. It is deterministic because microscopic variables such as the density of nuclei and their rate of formation are incorporated as parameters rather than stochastic variables. Various approaches have been taken to determine the macroscopic current density to overlapping diffusion fields of distributed nuclei under potentiostatic control.

Assumption 5 states that the endpoints measured in the toxicity tests on which the SSD is based must be ecologically relevant. Mortality is the most frequently studied endpoint in laboratory tests. In chronic tests, endpoints such as reproduction and inhibition of growth are also studied. Forbes et al. (2001a) argued that individual-level endpoints like survival, fecundity, and growth may not reflect effects at the population level (Assumption 5). They recommended that additional consideration be given to the relative frequency of different life cycle types, to the proportion of sensitive and insensitive taxonomic groups in communities, and to the role of density-dependent influences on population dynamics (see also Forbes and Calow 2002).

Taking into account that the exchange current density depends on the concentration of reacting ion, it follows that the growth of dendrites12,21,22 inside the diffusion layer of the macroelectrode is in fact under mixed activation-diffusion control. Hence, it can be expected that the process on the microelectrodes placed on the surface of the inert macroelectrode can be under mixed control. This is because the charge transfer occurs on the microelectrodes, while the mass-transfer limitations are related to the diffusion layer of the macroelectrode.

Second, the populations of herring and sprat would decrease because of an increase in predation (Koster et al., 2001, 2003). As a consequence of their decrease in population size, the density-dependent competition within and among these species for zooplankton prey (Mollmann et al., 2005 Casini et al., 2006) would decrease. This should subsequently lead to an increase in their growth rates and condition (Mollmann et al., 2005 Casini et al., 2006). Given that the demand by humans for Baltic herring has partly decreased because of their lower condition, larger and better-conditioned herring would make these fish more attractive to human consumers.
