As the first step of methylmercury (MeHg) entry into aquatic food web, phytoplankton uptake MeHg is crucial in determining final human exposure risks. availability to plankton regulated by dissolved organic matter (DOM) water, while these impacts could vary largely among different DOM sources. In this study, we investigate sources bioconcentration three freshwater algae ( S. quadricauda, Chlorella and Microcystis ) a microcosm system. We found that algae-derived prohibit cellular percentage up 77‒93%, yet soil-derived didn't display similar inhibition effects. characterization excitation‒emission matrices, fourier transform infrared spectrum, ultra‒high performance liquid chromatography‒tandem quadrupole time flight mass spectrometry indicated molecular size S-containing compounds rather than thiol concentrations had played roles regulating algal uptakes. Climate change increasing nutrient loadings from activities may affect growth freshwater, ultimately changing qualities DOM. Potential changes on together with other fields should be integrated when exploring Hg cycling accessing their risks beings or wild life.
