Toluene safe concentration for toll gate keepers at Kebon Jeruk Jakarta Indonesia

Toluene is one of the BTX compounds with a strong and distinctive aroma. When inhaled, this can affect the nervous system and body coordination and cause headaches. At constant exposure, toluene compounds can cause more serious health risks that can cause death. This study aims to determine the safe concentration of toluene in Kebun Jeruk toll gate officers, Jakarta. The population in this study were all 20 Kebun Jeruk toll gate keepers divided into two area points of toll gate 1 and toll gate 2. This study used manually calculated quantitative data analysis through safe concentration calculation in environmental toxicology concepts. Safe concentration data in Jakarta Kebon Jeruk toll gate keepers were obtained from experimental animals’ body weight (W animals), body area (BSA animals), workers’ characteristics including body weight (W), height (h), body surface area (BSA), breathing rate (BR) and working duration (t). In addition, data on the concentration of benzene (C), animal km, human km, NOAEL and the safe dose of toxin were also used. The concentration of toluene in air that enters the workers body through inhalation measured at two average points was 0.00125 mg/m3 (0.00033 ppm). The value obtained is still far below the toluene threshold value determined by the Minister of Manpower and Transmigration Regulation Number Per.13/Men/X/2011 of 2011. The calculated safe concentration of toluene shows a result of 0.0922 mg/m3 (0.0245 ppm) which is still in the safe category. This level must be maintained to assure its level does not increase.
