Abstract

ABSTRACT 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, child’s 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 profile’s 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). Key words :Blood lead content, blood profile, gas attendants.

Abstract

Well water is one of the main water sources to meet the needs of the community, especially in rural areas. However, the quality of well water often does not meet health standards because it contains heavy metals such as iron (Fe). Therefore, a simple and environmentally friendly alternative technology is needed that can be utilized by the community. One method used is filtration using natural adsorbent media, one of which is coffee shell charcoal. This study aims to determine the effectiveness of coffee shell charcoal in reducing Fe levels in well water. The research design used was a true-experimental with a one-group pre-test and post-test. Well water samples were tested for Fe levels before and after filtration using coffee shell charcoal with varying media thicknesses (40, 50 & 60 cm) and contact times (30, 45 & 60 minutes). Laboratory analysis was carried out using the Atomic Absorption Spectrophotometry (AAS) method. The results showed that the average percentage of Fe reduction reached 75,36%. Media thickness and contact time significantly affected the effectiveness of Fe reduction with p values ​​of 0,03 and 0,01, respectively (p < 0,05). A medium with a thickness of 60 cm and a contact time of 60 minutes provided the most optimal results, with final Fe levels below the threshold set by Minister of Health Regulation No. 32 of 2017 (≤ 1 mg/L). In conclusion, coffee husk charcoal has proven effective as a simple filtration medium for reducing Fe levels in well water.
