A distinction between contamination and pollution is useful when we
wish to consider what strategies to adopt in researching the impact
of anthropogenic activities on the marine environment.
Contamination strictly refers to the chemical burden imposed on the
system and is evaluated in terms of the concentrations of chemical
compounds in various abiotic (e. g water, suspended particulate
matter, sediments) and biotic (plant and animal, pelagic and
benthic) components. The concept of pollution, on the other hand,
infers an assessment of biological response to the measured levels
of contamination. This response may be measured at various levels
of biological organisation, from molecular events within the cell
to changes in such ecosystem properties as nutrient flux and
biological productivity. Such measures of biological response need
not infer any value judgements regarding putative damage or
disturbance to the natural systems, although the biologist will
usually have in mind a reference point of normality with which to
compare the measured response; departure from this "normality" may
then provide a quantitiative index of disturbance. The challenge to
scientists engaged in research into marine contamination and
pollution is to weld the chemical and biological elements together
(always with reference also to the physical features of the
environment) so as to provide a coherent framework for the
quantitative evaluation of environmental response.
