DETERMINATION OF LEAD IN THE BLOOD OF SOME CHILDREN IN THE TOWN OF BERAT, ALBANIA

Blood levels were determined in 145 blood samples with lead content ra nging fi om 3.5 to 551 mu g/100ml (38 samples are collected in 1992, t he balance in 1993). Lead was determined in samples collected in 1992 by two AAS methods: (1)Lead chelation and solvent extraction followed by flame AAS and (2) Dilution of sample with water followed by electro thermal atomization. In both methods deuterium source background corre ction was used. The concentration of lead in these samples were also d etermined in another laboratory. The three series of results for the 3 8 samples were compared by both one-way ANOVA and then by paired t-tes t techniques.
