title: [Influence of alcohol on the behavior of dose and effect indicators in workers exposed to inorganic lead: unexpected behavior of ZPP].
abstract: A study was carried out on 65 male workers heavily exposed to lead in the ceramic tile manufacturing industry in order to assess the effects of alcohol on the biological indicators of lead (PbB, ALA-D, ALA-U, ZPP). All subjects selected for the study had PbB levels greater than or equal to 60 micrograms/dl, normal levels of serum iron and no haemoglobin disorders. The subjects were divided into three groups according to alcohol intake checked by anamnestic investigation, mean corpuscular volume (MCV) values and liver function parameters, as follows: Group A--27 subjects, controls, with daily alcohol intake less than 80 ml, MCV less than or equal to 95 mu 3, normal GGT, AST and ALT levels; Group B--20 subjects, heavy drinkers, with daily alcohol intake greater than or equal to 80 ml, MCV greater than 95 mu 3, occasionally high GGT, but normal AST and ALT values; Group C--18 subjects, heavy drinkers, with daily alcohol intake greater than or equal to 80 ml, MCV greater than 95 mu 3, abnormal GGT, AST and ALT levels. The length of lead exposure did not significantly differ in the three groups. The well-known effects of ethanol intake on PbB, ALA-D and ALA-U values were confirmed, with the following mean values in the three groups: Group A: PbB = 66.0 (micrograms/dl), ALA-D = 10.3 (mU/ml r.c.), ALA-U = 8.4 (mg/l); Group B: PbB = 68.3 (micrograms/dl), ALA-D = 6.7 (mU/ml r.c.), ALA-U = 9.1 (mg/l); Group C: PbB = 71.5 (micrograms/dl), ALA-D = 4.6 (mU/ml r.c.), ALA-U = 12.7 (mg/l).(ABSTRACT TRUNCATED AT 250 WORDS)
