Ecotoxicology
Biomarkers are being used to identify the effects of water contamination on aquatic organisms. Benthic macro-invertebrates reside in the sediment on the bottoms of streams, which is where many contaminants settle. These organisms have high exposure to the contamination, which makes them good study species when detecting pollutant concentrations and pollution impacts on an ecosystem [1]. There are a variety of biomarkers within an aquatic organism that can be measured, depending on the contaminant or the response in question. There are also a variety of contaminants within water bodies. To analyze the impact of a pollutant on an organism, the biomarker must respond to a specific contaminant within a specific time frame or at a certain concentration [2]. The biomarkers used to detect pollution in aquatic organisms can be enzymatic or non-enzymatic [3] [4].
Rachel Carson, the author of
Silent Spring, raised the issue of using organochlorine pesticides and discussed the possible negative effects that said pesticides have on living organisms.
[5] Her book raised ethical issues against chemical corporations that were controlling the general reception of the effect of pesticides on the environment, which pioneered the need for
ecotoxicological studies. Ecotoxicologial studies could be considered the precursors to biomarker studies.
[6] Biomarkers are used to indicate an
exposure to or the effect of
xenobiotics which are present in the
environment and in organisms. The biomarker may be an external substance itself (e.g.
asbestos particles or
NNK from tobacco), or a variant of the external substance processed by the body (a
metabolite) that usually can be quantified.
