AVALIAÇÃO DOS TEORES DE Pb, Cd, Sn, Co, Hg, Mo E As EM SOLOS DA PENÍNSULA FILDES - ANTÁRTICA
Antarctic Continent is one of the few places that has not been explored at all, but studies show that this place is suffering interference by human activities. Therefore, monitoring of this region becomes very important. After optimization and verification of the methodology, the concentrations of P...
