Arsenic can modify the urinary excretion of porphyrins in animals and
humans. Arsenic also interferes with the activities of several enzymes
of the heme biosynthesis pathway, such as aminolevulinate synthase (A
LA-S), porphobilinogen deaminase (PBGD), uroporphyrinogen In synthase
(Uro III S), uroporphyrinogen decarboxylase (URO-D), coproporphyrinoge
n oxidase (COPRO-O), ferrochelatase and heme oxygenase (H-O). This rev
iew deals with HPLC-based techniques for the analysis of porphyrins in
human and rodent urine and several heme enzymes with discussion on th
eir usefulness as early biomarkers of arsenic toxicity.
