Abstrak: Asbes merupakan nama yang diberikan untuk kelompok dari enam serat mineral berbeda yang terjadi secara alami di lingkungan. Dalam dunia industri, terkadang masih ada yang menggunakan Asbestos Containing Materials (ACMs) sebagai insulasi dan gasket. Penelitian ini dilakukan di PT X Tahun 2011. Tujuan penelitian ini adalah untuk mengetahui lokasi, kondisi ACMs, serta nilai risiko ACMs. Penelitian ini dilakukan dengan cara bulk sampling, dan diidentifikasi menggunakan Polarized Light Microscopy (PLM). Pengambilan sampel dilakukan dengan menggunakan core-cutter untuk memperoleh sampel dengan berdiameter 2-3 cm. Dari hasil bulk sample sebanyak 42 sampel, diketahui ada 18 sampel signifikan ACMs dan 24 sampel non-ACMs. Oleh karena itu, perlu dilakukan monitoring dan pengelolaan terhadap ACMs tersebut.

Asbestos is the name given to a group of six different mineral fibers that occur naturally in the environment. In industrial world, there are some industries that still use Asbestos Containing Materials (ACMs) as insulation and gaskets. This research was conducted in PT X at 2011. The purpose of this study was to determine location, condition of ACMs, and risk value of ACMs. The research was done by bulk sampling, and identificate used Polarized Light Microscopy (PLM). Sample had taken with core-cutter to get samples with diameter of 2-3 cm. From the bulk sample got 42 samples, 18 have significant ACMs and 24 non-ACMs. Therefore, have to monitoring and management for ACMs.

Abstrak: We employed the parametric G formula to analyze lung cancer mortality in a cohort of textile manufacturing workers who were occupationally exposed to asbestos in South Carolina. A total of 3,002 adults with a median age of 24 years at enrollment (58% male, 81% Caucasian) were followed for 117,471 person-years between 1940 and 2001, and 195 lung cancer deaths were observed. Chrysotile asbestos exposure was measured in fiber-years per milliliter of air, and annual occupational exposures were estimated on the basis of detailed work histories. Sixteen percent of person-years involved exposure to asbestos, with a median exposure of 3.30 fiber-years/mL among those exposed. Lung cancer mortality by age 90 years under the observed asbestos exposure was 9.44%. In comparison with observed asbestos exposure, if the facility had operated under the current Occupational Safety and Health Administration asbestos exposure standard of < 0.1 fibers/mL, we estimate that the cohort would have experienced 24% less lung cancer mortality by age 90 years (mortality ratio = 0.76, 95% confidence interval: 0.62, 0.94). A further reduction in asbestos exposure to a standard of < 0.05 fibers/mL was estimated to have resulted in a minimal additional reduction in lung cancer mortality by age 90 years (mortality ratio = 0.75, 95% confidence interval: 0.61, 0.92).
