Abstract
In a total number of 275 dogs of various ages, sex and breed, blood lead concentrations (BLC) and erythrocyte ALAD activity were measured. Sixty-six of the dogs were living in lead mining areas (Group A), 157 in urban areas (Group B) and 52 in rural areas (Group C) of Greece. Mean BLC differed significantly (P < 0.05) between locations and were 326,97 and 68 micrograms/L, respectively. Mean ALAD activity was significantly different (P < 0.05) only between Groups A and B as between groups A and C. A significant (P < 0.05) negative correlation existed between BLC and ALAD activity. A normal range of erythrocyte ALAD activity of 807-992 mumol/PBG/LRBC/h was established for dogs. None of the 33 Group A dogs and 2 of the Group B dogs that had a BLC of 350 micrograms/L presented clinical signs indicating acute or chronic lead intoxication. No erythrocyte basophilic stippling or large number of nucleated red blood cells were seen in the 30 dogs of Group A with BLC > 350 micrograms/L.
