Introduction: Benzo(a)pyrene is a class of PAH which is classified as a carcinogenic compound (probably carcinogenic) in humans and animals. After exposure, benzo(a)pyrene which enters the human body through inhalation pathways, is directly absorbed in the body and distributed in the lungs, skin, and liver, then binds to DNA, RNA, and protein. After entering the human body and biotransformation, benzo(a)pyrene is excreted in the form of hydroxylated metabolites in urine or feces. 1-hydroxypyrene (1-OHP) in urine is the most common metabolite used as exposure biomarkers of benzo(a)pyrene compounds. Benzo(a)pyrene concentration measurements were carried out at three points in each school using tube sorbents with charcoal filters and analyzed using the fluorescence method. Analysis of 1-hydroxypyrene in urine is carried out using HPLC with a fluorescence detector. Objective: To see the relationship of exposure to benzo(a)pyrene to urine 1-hydroxypyrene concentration. Method: This study is a quantitative study with a cross-sectional design, the sample in this study amounted to 76 people, the sample distribution was made by probability proportional to size (PPS), the sampling used purposive sampling. Results: The average BaP concentration in the indoor air of public elementary schools around the West Jakarta's main road segment is 0.0059 mg/m3, and the average BaP concentration in outdoor air is 0.0031 mg/m3. The average BaP concentration in indoor air in high exposed schools is 5.6 times higher (0.0102 mg/m3) compared to schools exposed to a low exposure (0.0018 mg/m3). The average 1-OHP concentration in the urine of public elementary school students around the West Jakarta main road segment is 12.146 µmol/mol creatinine. The average concentration of 1-OHP in the urine of high-exposed school students was 1.2 times greater (13,363 µmol/mol creatinine) compared to low-exposed schools (10,929 µmol/mol creatinine). Conclusion: The relationship of BaP exposure in indoor air to the concentration of 1-OHP in the urine of students was positively patterned where there was a positive correlation between BaP exposure in indoor air to an increase in 1-OHP concentration in the urine of students (r = 0.229) meaning higher exposure to indoor air the higher the concentration of 1-OHP in the urine of students. The results of the statistical test explained that there was a significant relationship between exposure to BaP in indoor air and the concentration of 1-OHP in the urine of students (p = 0.046).
Penggunaan BBM di Indonesia masih didominasi oleh penggunaan bensin bertimbal, sehingga makin besar konsumsi energi BBM dari bensin bertimbal, maka makin tinggi tingkat pencemaran timbal (Pb) di udara ambien. Efek Pb terhadap sistem haemapoietic menyebabkan berkurangnya synthesis haemoglobin dan rnenyebabkan anemia. Di Kota Sukabumi saat ini penggunaan bahan bakar minyak (BBM) masih didominasi oleh penggunaan bensin bertimbal. Salah satu pekerja yang memiliki resiko tinggi terpapar Pb adalah pegawai UPTD Terminal Dinas Perhubungan Kota Sukabumi. Tujuan dari penelitian ini adalah untuk mengetahui Pb di udara ambien dan hubungannya dengan Pb dalam darah serta kejadian anemia pada pegawai UPTD Terminal Dinas Perhubungan Kota Sukabumi Tahun 2007. Desain penelitian yang digunakan adalah cross sectional. Populasi dan sampel adalah pegawai UPTD Terminal, dengan besar sampel sebanyak 44 pegawai yang diambil secara total sampling. Data yang diperoleh selanjutnya diolah secara statistik menggunakan teknik analisis distribusi frekuensi dan uji chi square. Dari hasil penelitian diperoleh bahwa : ada hubungan yang signifikan antara kadar Pb di udara ambien pada lingkungan kerja dengan kadar Pb dalam darah pada pegawai, ada hubungan yang signifikan antara kadar Pb dalam darah dengan kadar Hb darah pada pegawai, dan ada hubungan yang signiiikan antara umur dengan kadar Pb dalam darah pada pegawai UPTD Terminal. Selanjutnya, didapat bahwa tidak ada hubungan yang signifikan antara; kebiasaan merokok, memakai masker, dengan kadar Pb dalam darah pada pegawai UPTD Temainal. Hasil penelitian ini semakin memperjelas betapa pentingnya pengendalian pencemaran udara khususnya pencemaran Pb di udara Upaya penghapusan bensin bertimbal sudah tidak dapat ditunda lagi untuk mencegah dampak kesehatan dan kerugian biaya yang ditanggung oleh masyarakat.
BBM usage in Indonesia still dominated by lead gasoline, so that consumption of BBM energy from lead gasoline increasing, then lead (Pb) pollution level in ambient air is more and more increasing. Pb effect toward haemopoietic system caused the decreasing of hemoglobin synthesis and causing anemia. At Sukabumi recently, BBM usage still dominated by lead gasoline usage. One of the workers that has high risk of exposed to Pb is Terminal UPTD employee of Sukaburni City Transportation Department. The purpose of the study is to find out the relation between Pb in the ambient air and Pb in blood and anemia cases of transportation department a employees of UPTD terminal at Sukabumi 2007. Research design used is cross sectional. Population and sample are Tenninal UPTD employee, with total samples of 44 employees that gathered by total sampling. Further obtained data processed statistically using analysis technique of frequency distribution and chi square test. From research result, obtained that: there is significant relation between Pb level in ambient air of working environment with Pb level in employees blood, there is significant relation between Pb level in blood and blood Hb in employees, and there is significant relation between age and Pb level in employees blood of Terminal UPTD. Accumulation of Pb level could not define in those employees blood because exposed to Pb in ambient air of work environment Furthermore, obtained that there are no signiiicant relations between smoking behaviors along as well as using mask with Pb level in employees? blood of Terminal UPTD. The result of this research clarifies the importance of controlling air pollution especially from Pb contamination. The effort for elimination of gasoline containing Pb can not be delay to prevent the impact to health and the loss of expense that burden by the people.
