Plant metabolism support for MRL determination
Record Type:Study
Plant metabolism support for MRL (Maximum Residue Levels) determination is a factor in establishing the highest amount of pesticide residue expected in food when pesticides are applied correctly. Typically, a labeled pesticide is applied to crop plants and various samples of the plant are analyzed for total radioactive residue (TRR) (via combustion and total 14C analysis) and metabolite identification. Plant studies leverage information such as translocation of residues from one part of the plant to another, or proportion of residues which can be removed by surface wash. The data can contribute to the OECD MRL calculator.
About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC.Learn more about our commitment to replacing, reusing and refining nonclinical research models.
