AN EMERGING BIOMONITORING APPROACH FOR DETECTING CHANGE IN AQUATIC ENVIRONMENTS
Biomonitoring tools that detect and assess change in aquatic environments quickly and reliably are needed. Metabolomics is an emerging approach that has the potential to overcome shortcomings of current biomonitoring approaches. However, metabolomics is not currently recognized by managers as an alternative for biomonitoring. Here we evaluate and review the strengths and weaknesses of metabolomics as a biomonitoring tool and present a case study investigating exposure of benthic macroinvertebrates (BMI) to municipal effluent. To determine the potential of metabolomics as a biomonitoring tool, published metabolomic studies were reviewed and results compared against criteria for an ideal biomonitoring tool. Metabolomics met a majority of the criteria, such as reliability, detection of human impact, and simple sampling methods. Results from the case study show that metabolomics of BMI was able to detect differences between affected and reference sites and the spatial extent of exposure to municipal effluent. Our findings further demonstrate that metabolomics could be immediately adopted as a powerful tool for conducting bioassessments similar to current approaches. However, metabolomics shows even more promise in its ability to detect diagnostic effects of stressors, but more research is needed in this area.
