摘要

The primary reason for conducting ecotoxicology research is to obtain information that can be used by regulators to protect the environment from the many chemicals accidentally or intentionally released into the environment. Hence, to be maximally useful to regulators, ecotoxicology research should address environmentally relevant concentrations of chemicals. Recent advances in analytical chemistry, such as the development of tandem mass spectrometry, have enabled accurate measurements of the concentrations of most chemicals present in the environment. Advances in modeling have also improved our knowledge of the likely concentrations of chemicals in the environment. Thus, we now have a good idea of what the environmentally relevant concentrations of most chemicals are. Researchers interested in whether or not chemicals harm wildlife should be able to conduct their research using concentrations of test chemicals that are representative of those experienced by wildlife. Judging by the frequency that the words "environmentally relevant" seem to be appearing in the titles of ecotoxicology publications, it might be assumed that this was indeed occurring; that we are moving from research that determined lethal concentrations of chemicals to research that was much more realistic. But is that opinion correct? To shed light on whether or not ecotoxicology research is progressively becoming more environmentally relevant, we assessed the use of the words "environmentally relevant", combined with exposure or level or concentration or dose (and variants thereof), in the titles of publications in Web of Knowledge (Figure 1).
