    Abstract : Vattendragen i Nicaraguas centrala bergsområden är utsatta för hög miljöpåverkan. I över hundra år har kvicksilver använts för att utvinna guld i dessa områden, vilket förorenat vattenresurserna. Det har gjorts få undersökningar av områdets vattenkvalité, vilket främst beror på avsaknaden av infrastruktur. READ MORE
