Abstract Background Glyphosate is a broad-spectrum, non-selective systemic herbicide with commonly assumed low potential for accumulation in biota. Nevertheless, glyphosate has been shown to bioaccumulate the tissues of several organisms. To understand bioconcentration dynamics fish, brown trout ( Salmo trutta forma fario ) different age were exposed concentrations glyphosate, formulation Roundup® LB Plus, and major transformation product aminomethylphosphonic acid (AMPA) two, three, or four weeks at temperatures laboratory. Mortality rates determined, tissue samples collected end experiment ascertain AMPA residues by liquid chromatography coupled mass spectrometry (LC–MS/MS). Results Brown mortality during exposure was considerably higher 15 °C than 7 °C. Also, significant increase containing muscle, head, backbone, caudal fin increasing observed. Six-month-old fish contained more per kg wet weight after ten-month-old fish. The factors (BCFs) much °C, but both cases decreased concentrations. BCF formulated one parent compound. Approximately 30–42% organ-absorbed remained even when kept clean water lacking test substances three termination exposure. Conclusion Our study demonstrated that there an interaction between ambient temperature terms toxicity. Further it surrounding media lead significantly increased these tissues, although neither nor bioaccumulation animal expected due high solubility this chemical. As consequence, uptake humans through consumption contaminated edible very likely.
