title: [Lead concentrations in the blood of residents of the city of Monterrey, Nuevo León].
abstract: Six hundred and seventy one inhabitants from Monterrey City, Mexico, were studied during an eight months period to know their blood lead (PbB) content, as a biological indicator of environmental lead exposure in that city. Thirty per cent of these population were males and 70 per cent were females. The group was divided by sex in workers and non-workers. Men were (81.6 per cent) both, blue and white collar, and showed non-occupational lead exposure. Students and housewives were considered as a non-workers group and accounting 18.3 per cent in that group. For men the mean value of blood lead in workers and non-workers was 14.38 and 14.08 micrograms/dl, and for women it was 13.11 and 13.35 micrograms/dl for workers and non-workers, respectively. The entire group was divided again in smokers; and non-smokers; while smokers had a mean PbB of 15.11 micrograms/dl, the non-smokers group had a PbB mean value of 12.92 micrograms/dl, which is 2.19 micrograms/dl more higher in those having the smoking habit. No significant differences were found between blood lead content and alcoholism as well as "lead grazed pottery" used as food ware. Statistical analysis for blood lead (PbB) and sex (t-Student), PbB and smoking habit (ANOVA) and PbB and place of residence were all significant (p < 0.05). An increment of 28 per cent in PbB was found in the group of less than 10 years of age (17.23 micrograms/dl) when compared to the mean value of PbB in the whole population (13.60 micrograms/dl).(ABSTRACT TRUNCATED AT 250 WORDS)
