Erythrocyte glucose-6-phosphate dehydrogenase (1.1.1.49) deficiency in Antalya province, Turkey: an epidemiologic and biochemical study.

Glucose-6-phosphate dehydrogenase (1.1.1.49) activity was assessed in 1986-1988 in blood samples from 1,521 individuals from 375 families living an Antalya city and adjacent villages by Beutler's fluorescence spot test. The families were randomly selected by the State Statistical Institute. Complete deficiency occurred in 7.4% of males and 1.8% of females. Mean enzyme activity was 6.77 +/- 1.07 IU/g Hb in normals and ranged between 0 and 0.48 IU/g Hb in those considered deficient. Kinetic measurements made with partially purified enzyme showed that GdB+ and GdB- variants were present in normal and in deficient subjects, respectively.

Lead, chromium, and cadmium exposure during abrasive blasting.

An evaluation of lead, cadmium, and chromium exposure was conducted during abrasive blasting of a steel bridge to remove paint in preparation for repainting. Airborne lead concentrations were measured at several locations inside the containment structure, as well as near the workers' breathing zones. Airborne cadmium and chromium were also measured in the containment area. Blood lead levels were monitored in each worker. Airborne lead and cadmium levels in containment exceeded the Occupational Safety and Health Administration's permissible exposure limits by factors of 219 and 3.1, respectively. The use of supplied air-blasting helmets will not effectively reduce workers' lead exposure to the permissible exposure limits when airborne levels are as high as were measured in this study. Studies are needed to evaluate additional engineering controls and alternative paint removal methods. Evaluation of workers' exposure to lead and other hazardous metals is needed for projects involving abrasive blasting. Medical surveillance for cadmium and lead may be necessary for similar projects.

Hemoglobinopathies in the district of Antalya, Turkey.

A screening program was conducted to ascertain the incidence of hemoglobinopathies in the district of Antalya, Turkey. The survey sample was selected from the household registration forms of health centers by systematic random sampling. Heparinized blood samples were collected from 1,616 subjects from 884 families. The prevalence of beta thalassemia traits with increased Hb A2 was 10.2%. This is higher than that found in previous studies performed in Antalya. The prevalence of abnormal hemoglobins (Hbs) was found to be 0.8%. Four subjects had Hb AS; five had Hb D-Los Angeles (B 121 [GH4] Glu-Gln); one had Hb Ube-2 (68 [E1] Ans-Asp), one had Hb P-Nilotic (fusion between B 22 and) and two had Hb D-like variants.
