Hubungan Kadar Pb dalam Darah dengan Profil Darah pada Petugas Operator Stasiun Pengisian Bahan Bakar Umum di Kota Semarang Timur.

Background, Lead (Pb) constitutes as main pollutant in the air of the cities besides the pollution of sulphur dioxide (SO2), suspended particulate matte (SPM)r, nitrogen oxide (NOX ), and carbon monoxide (CO). The impacts of lead (Pb) exposure on health are kidney disorder, hypertension, anemia, central nerve disorder, behaviourial changes, fertility disorder, miscarriage, childs IQ decrease, and the disorder in formation of hemoglobin. Objective, to find out the correlation between the level of lead (Pb) exposure and the blood profiles of gas station workers located in the eastern part of Semarang City. Method, the research used a cross sectional design with the number of samples were 39 worker. Independent variable was the level of lead content in blood, while the dependent variable was blood profile and confounding variables were health history, intake of energy and protein , vitamin B12 , folic acid , vitamin C , the habit of drinking tea, drug use, use of self protective device, smoking habit, and alcohol consumption. Results, the average of blood lead concentration were measured 13,35 µg/dl, the blood profile that including the level of haemoglobin, leucocyte, hematocrit, erytrocite, MCV, MCH, MCHC, still in normal limits, variable of blood lead concentration had significant correlation with the level of hemoglobin and the level of hematocrit, with OR = 1,388; 95 % CI= 1,094 1,761 for haemoglobin and OR= 1,358 ; 95 % CI= 1,095 1,685 for hematocrit respectively. Conclusion, the level of lead content in blood which is above normal act as risk factor of decreasing the level of hemoglobin and hematocrit by 1,388 times and 1,58 times respectively, compared with that of normal level of lead content in the blood. It is recommended that the gas station worker wear the self protective devices (masker) while working in the gas station in order to reduce the exposure of lead (Pb) from the motor vehicle exhaust and perform regular medical checkup with certain interval (at least once a year).
