Considering the linguistics aspects present in the poem,

      A formação freqüente de grandes volumes de pirita (FeS₂) em uma variedade de depósitos minerais favorece a formação de soluções ácidas ferruginosas, conhecidas como “drenagem ácida de minas” . Esse fenômeno tem sido bastante pesquisado pelos cientistas e representa uma grande preocupação entre os impactos da mineração no ambiente. Em contato com oxigênio, a 25 º C, a pirita sofre reação, de acordo com a equação química:
