Lead toxicity | Occupational Medicine | Oxford Academic
Lead is known to affect haem synthesis by poisoning enzymes at several stages in the haem synthesis pathway and this knowledge has led to methods used for biological effect monitoring. Raised urinary aminolaevulinic acid (ALA) levels and raised zinc protoporphyrin must be differentiated from acute porphyrias or sideroblastic anaemia .Chat Online
