Abstract

Occupational exposure to benzene from fuel oil in workshop motorcycle workshop causes several health effects, depending upon the level and duration of exposure. Analysis of blood is important to access the status of worker’ health. The study aimed to assess the gather basic information required for protecting workers’ health and improve working conditions in the works sites by investigating the ESR levels. A comparative cross-sectional study conducted in Surabaya City, East Java-Indonesia, which involved 100 workers. The occupational data collected using a structured questionnaire while blood analysis parameters measured with an automated hematology analyzer. The result showed that leukocytes, erythrocytes, hemoglobin (HGB), hematocrit values (HCT), platelet, MCV, RDW, eosinophil, basophils, neutrophil rods, neutrophil segment, lymphocyte, monocytes were in normal value. Whereas, MCH, MCHC, ESR has shown in abnormal value as average 24.5 pg, 29.18 g/dL and 8.21 mm/h, respectively. Those value, especially in ESR value indicated the increasing concentration plasma viscosity. This is may cause by inflammation in the workers’ body. To prevent the hazardous effect of benzene exposure, occupational health should be implemented for workers in order to protect them from exposure to benzene.

Abstract

Pregnant women with high blood lead posed high risk to their fetus as placental transfer can occurs to the fetus. The objective of this study was to identify the relationship between blood lead and the neuropsychological score of women who were in their 3rd trimester of pregnancy. These respondents were undergoing a routine antenatal checkup at a teaching hospital located in Klang Valley areas. Blood lead concentrations were analyzed using graphite furnace Atomic Absorption Spectrophotometer (AAS). The neuropsychological scores were measured with WHO Neurobehavioral Core Test battery (NCTB). The test consists of 7 items, which made up of the Digit Symbol, Trail Making, Digit Span, Benton Visual Retention Test, Pursuit Aiming, Santa Ana Manual Dexterity, Reaction Time and Movement Time tests. The mean blood lead was 7.78±4.77 µg/dL. The mean score for the total NCTB test was 50.00±5.24. Statistical analysis showed blood lead concentrations were inversely correlated with the total NCTB score (r= –0.462, p≤0.01). The correlation was about 21.3%. The General Linear Model (GLM) showed that age (β= –0.15, p=0.017), weight (β=2.67, p=0.05) and height (β=–1.97, p=0.05) also influence the total neuropsychological scores. In conclusion, blood lead reduces the total neuropsychological scores. The scores for each of the 7 items were inversely and significantly correlated with blood lead concentrations except for the Trail Making and Santa Ana Manual Dexterity tests.
