Their data showed mercury contamination from informal gold mining making its way into the biodiversity hotspot's mammals — from rodents to ocelots to titi monkeys. Leaders from the eight countries around the Amazon meeting in Brazil next week will discuss how to end illegal gold mining. While the scientists began testing for mercury at Los Amigos in 2021, some of the samples were gathered as early as 2018. During Reuters' visit to Los Amigos, scientists caught rodents in metal traps baited with peanut butter and snagged birds and a bat in mist nets floating through the forest. In 2021, mining arrived on Los Amigos' doorstep.
