“…Simulation Base case simulation covers a period that goes from 1940 to 2020, considering that Acadia National Park (Maine, USA) was affected by a largescale wildfire in 1947. Initial values for the only existence of this first model in 1940, "Hg in atmosphere", are calculated considering 2•10 -7 g/m 3 (Vinogradova et al, 1985), so the amount of Hg present in the atmosphere in 1940 is 632 g. The length of time used -the time horizon-must be long enough to show the dynamic changes. The fire started in October 1947 and ended in November that same year; therefore, we selected a time step of 0.25 year, which will give a more accurate simulation.…”

Mercury (Hg) mobilization and accumulation in the environment is directly related to forest fires. Biomass burning accounts for about 13% of the total contribution of Hg from natural sources. The aim of this work is to contribute to the knowledge of how wildfires modify mercury compounds behaviour and the effects it has in the Hg cycle, based on a systematic bibliographic review and analysis. Systems dynamics is an adequate focus to analyze the mobilization of Hg due to wildfires, which meets all the requirements to be studied by multimedia modelling. The development and application for the first time of a dynamic multimedia model of Hg taking into account specifically the influences of wildfires is one of the novelties of this work. Different scenarios show that an increase in the number of fires will consequently increase the mercury emitted into the atmosphere, modifying its natural cycle, producing a long-term modification of Hg compositions and concentrations in the different media. Hg movement caused by wildfires can cause complications in living beings and alter the ecosystems. This study found that the Hg soil content could as well be an indicator to measure the impact of fire on the environment. This model can also be generalized to conduct additional studies under comparable conditions, helping to understand the importance of forest fires in global Hg cycles. Graphical abstract
