Wildfire ashes: evaluating threats on the Pantanal wetland reserve (Mato Grosso, Brazil) using ecotoxicological tests.

In 2020, the largest continuous wetland area on the planet, the Brazilian Pantanal, experienced an unprecedented fire that affected the entire ecosystem. Our goal was to elucidate the effects of ash presence following the fire events. We quantified the impact of ashes, collected in four Conservation Units, on soil, water, and atmosphere.
