Pendahuluan: Benzo(a)pyrene merupakan salah satu golongan PAH yangdiklasifikasikan sebagai senyawa yang bersifat karsinogen (probably carcinogenic)pada manusia dan hewan. Setelah terpajanan, benzo(a)pyrene yang masuk kedalamtubuh manusia melalui jalur inhalasi, langsung terabsorpsi didalam tubuh danterdistribusi dalam paru, kulit dan hati, lalu berikatan dengan DNA, RNA dan protein. Setelah memasuki tubuh manusia dan biotransformasi, Benzo(a)pyrene diekskresikan dalam bentuk metabolit terhidroksilasi dalam urin atau feses. 1-hydroxypyrene (1-OHP) dalam urin merupakan metabolit yang paling umum digunakan sebagai biomarker pajanan dari senyawa benzo(a)pyrene. Pengukuran konsentrasi benzo(a)pyrene dilakukan pada tiga titik di setiap sekolah menggunakan sorben tube dengan filter charcoal, dan dianalisis menggunakan metode fluoresensi. Analisis 1-hydroxypyrene dalam urin dilakukan menggunakan HPLC dengan detektor fluoresensi. Tujuan: untuk melihat hubungan paparan benzo(a)pyrene terhadap konsentrasi 1-hydroxypyrene pada urin. Metode: Penelitian ini merupakan penelitian kuantitatif dengan desain cross sectional, sampel dalam penelitian ini berjumlah 76 orang, pembagian sampel di buat secara probability proportional to size (PPS), pengambilan sampel menggunakan purposive sampling. Hasil: Rata-rata konsentrasi BaP di udara indoor sekolah dasar negeri di sekitar ruas jalan utama Jakarta Barat sebesar 0,0059 mg/m3, dan rata-rata konsentrasi BaP di udara outdoor yaitu 0,0031 mg/m3. Rata-rata konsentrasi BaP di udara indoor pada sekolah terpajan tinggi yaitu 5,6 kali lebih tinggi (0,0102 mg/m3) di bandingkan sekolah yang terpajan terpajan rendah (0,0018 mg/m3). Rata-rata konsentrasi 1-OHP pada urin siswa sekolah dasar negeri di sekitar ruas jalan utama Jakarta Barat adalah 12,146 μmol/mol kreatinin. Rata-rata konsentrasi 1-OHP pada urin siswa sekolah terpajan tinggi 1,2 kali lebih besar (13,363 μmol/mol kreatinin) di bandingkan sekolah terpajan rendah (10,929 μmol/mol kreatinin). Kesimpulan: Hubungan pajanan BaP di udara indooor terhadap konsentrasi 1-OHP pada urin siswa berpola positif dimana terdapat korelasi positif antara pajanan BaP di udara indoor terhadap peningkatan konsentrasi 1-OHP pada urin siswa (r=0,229) artinya semakin tinggi pajanan BaP di udara indoor maka semakin tinggi konsentrasi 1-OHP pada urin siswa. Hasil uji statistik menjelaskan ada hubungan yang signifikan antara pajanan BaP di udara indoor dengan konsentrasi 1-OHP pada urin siswa (p=0,046). ...... 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 crosssectional 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).

Konsentrasi 1-Hydroxypyrene di dalam urin dipengaruhi beberapa faktor pajanan, salah satunya adalah konsentrasi pajanan Benzo (a) Pyrene di udara. Didalam penelitian ini selain meneliti hubungan BAP dan 1-OHP juga diteliti faktor lain yang dapat menpengaruhi konsentrasi 1-OHPu, yaitu : karakteristik individu (Jenis kelamin, berat badan dan IMT), lama pajanan, dan sumber pajanan lain (makanan bakar/panggang, bahan bakar memasak, perokok dirumah). Penelitian ini bertujuan untuk mengetahui hubungan pajanan BAP dan konsentrasi 1-OHPu dan faktor lain yang mempengaruhi. Penelitian cross-sectional ini dilakukan dengan mengambil sampel udara dilingkungan SMPN 16 Bandung, dan memeriksa 36 sampel urin siswa kelas 2 SMPN 16 untuk pemeriksaan 1-OHPu, dan dilakukan wawancara terstruktur dengan kuisioner. Hasil penelitian ini menunjukkan tidak adanya hubungan antara BAP di udara dan 1-OHPu siswa kelas 2 SMPN 16. Kesimpulan penelitian ini : faktor paling mempengaruhi konsentrasi 1-OHPu siswa kelas 2 SMPN 16 secara berurutan adalah : bahan bakar memasak dirumah, adanya perokok dirumah, makanan bakar/panggang, IMT, dan lama pajanan. ......

Emisi mesin diesel (diesel exhaust) merupakan bahan yang karsinogenik terhadap manusia (grup 1 IARC). Sektor transportasi merupakan penyumbang terbesar diesel exhaust di udara. Polisiklik Aromatik Hidrokarbon (PAH) merupakan komponen yang banyak ditemukan dalam diesel exhaust. 1-Hidroksipirena (1-OHP) merupakan metabolit pyrene yang digunakan sebagai penanda adanya pajanan PAH. Penelitian ini bertujuan untuk mengetahui konsentrasi 1-OHP dalam urin terkait dengan pajanan diesel exhaust pada pekerja uji mekanis di Pusat Pengujian Kendaraan Bermotor Cilincing. Pajanan diesel exhaust diukur melalui konsentrasi personal PM2,5, PM1, PM0,5, dan PM0,25. Penelitian dilakukan pada 19 petugas uji mekanis dan 18 orang pembanding. Pengukuran partikulat dilakukan menggunakan pompa Leland Legacy dengan Sioutas Cascade Impactor. Analisis 1-OHP dalam urin dilakukan menggunakan HPLC dengan detektor fluoresensi. Distribusi frekuensi 1-OHP dalam urin berkisar antara 11,72 - 61,88 µg/gr kreatinin urin. Hasil analisis menunjukkan terdapat rata-rata konsentrasi 1-OHP petugas uji mekanis signifikan lebih tinggi dibandingkan dengan kelompok pembanding (p=0,001). Terdapat korelasi positif dengan derajat keeratan kuat antara konsentrasi partikulat pada semua ukuran dengan konsentrasi 1-OHP dalam urin. Partikulat yang dihasilkan dari emisi mesin diesel merupakan kontributor utama terhadap peningkatan konsentrasi 1-OHP dalam urin petugas uji mekanis PKB Cilincing. ......Diesel engine exhaust is categorized as carcinogenic to human (group 1) by IARC in 2012. Transportation is the biggest contributor of diesel exhaust pollutant. Polycyclic Aromatic Hydrocarbons (PAHs) are the major compound of diesel exhaust that can be found on gas and particle phases. 1-Hydroxypyrene (1-OHP), a metabolite of pyrene, has been used extensively as a biological monitoring of exposure to PAHs. This study aimed to analyze the concentration of urinary 1-OHP related to diesel engine exhaust among vehicle testing mechanics at vehicle testing center Cilincing, Jakarta. Diesel exhaust exposure was measured by personal concentration of PM2,5, PM1, PM0,5, dan PM0,25. The subject was 19 vehicle testing mechanics and 18 non-mechanics as a comparator. Personal concentration of particulate matter collected using Leland Legacy pump and Sioutas Cascade Impactor and analyzed using gravimetric method. Urinary 1-OHP analyzed using High Performance Liquid Chromatography with fluorescence detector. Concentration of urinary 1-OHP ranging from 11,72 to 61,88 µg/gr creatinine. The result show that mean concentration of 1-Hydroxypyrene of mechanic group is significant higher than non-mechanic group (p=0,001). There is a positive correlation between particulate matter concentration in all size and urinary 1-hydroxypyrene concentration. In this study, particulate related to diesel engine exhaust is the main contributor of the increasing of urinary 1-hydroxypyrene concentration among vehicle testing mechanics.
