  6. Sufre kopuru handiagaitik eta koltana ateratzean hortik ateratzen den erradiazioagaitik
  7. Enpresek umeak erabiltzen dituzte eta baldintza kaxkarretan egoten dira, euria egitean baldintzak kaxkarragoak dira. Egunean 15 ordu edo gehiago egiten dituzte lan.

  11. Misiletarako erabiltzen da gai elektronikoak egiteko, horrela euren egonkortasuna hobetu egiten da aluminioarekin lortzen dena baino.
  12. Koltanetik niobioa ateratzen da eta horrek burdina erdoiltzea eragozten du turbinetan eta horrela hobeto eusten diote tenperatura altuei. Hori dela eta iraupena eta gasolina aurrezpena hobetu egiten dira.
