RESUMO
Hygienic and toxicological investigations of soil, plants, and animals have shown that the superphosphates made from Algerian phosphorites little differ from those made from the apatites of the Kola Peninsula. Superphosphates A and B should be referred to as hazard class IV and the superphosphates treated by ammonium should be classified as hazard class III.
