Serum S-aminolevulinic acid as a marker of lead toxicity in bovine

A study was conducted in 30 adult female bovine exposed to the lead pollutant to analyse the blood lead level and serum delta (S)-aminolevulinic acid. Blood lead level was estimated by atomic absorption spectroscopy and (S)-aminolevulinic acid by calorimetric method. Result of the study indicated that serum S-aminolevulinicacid increased in correlation with mean blood lead level. Serum S-aminolevulinic acid appeared as promising marker of lead exposure in absence of specific instrument like atomic absorption spectroscopy (AAS) and inductive coupled plasma spectroscopy (ICP).
