Artisanal and small-scale gold mining (ASGM) has generated high concentrations of mercury (Hg) in the vicinity of mining operations in Madre de Dios. Mercury is a toxic pollutant that upon entering a water body can be transformed into its organic, bioavailable and bioaccumulative form: methylmercury (MeHg). Research efforts and public attention have focused mainly on the presence of mercury in fish since its consumption is the main route of exposure for humans. However, monitoring fish, especially in locations that are remote and difficult to access, can be costly and logistically complex. Given this problem, this study evaluates the feasibility of using zooplankton and aquatic macroinvertebrates as alternative bioindicators of mercury contamination in aquatic ecosystems impacted by ASGM in the Madre de Dios region. The study proposes a standard operating procedure for collecting, preparing, and analyzing zooplankton and macroinvertebrate samples for monitoring mercury contamination in artificial ponds formed by gold mining. The results show that, considering the proposed methodology, macroinvertebrates of the family Belostomatidae and of the order Odonata are appropriate bioindicators to monitor mercury bioaccumulation in the study area. In contrast, the results for zooplankton were not satisfactory. This is the first study of this nature conducted for the Peruvian Amazon and highlights the need for environmental monitoring methods suitable for working conditions in the tropics.
